Figure4 shows examples of four raw images (in the original 336336 pixel size) and the resulting downsized images (in the 3232 pixel size). The data includes multiple age groups, multiple time periods and multiple races (Caucasian, Black, Indian). A review of building occupancy measurement systems. In addition, zone-labels are provided for images, which indicate with a binary flag whether each image shows a person or not. In total, three datasets were used: one for training and two for testing the models in open and closed-door occupancy scenarios. HHS Vulnerability Disclosure, Help M.J. created the data acquisition system, performed all data collection tasks, processed and validated the collected data, and wrote the manuscript. WebETHZ CVL RueMonge 2014. Hardware used in the data acquisition system. Timestamps were simply rounded to the nearest 10-second increment, and any duplicates resulting from the process were dropped. The Filetype shows the top-level compressed files associated with this modality, while Example sub-folder or filename highlights one possible route to a base-level data record within that folder. All collection code on both the client- and server-side were written in Python to run on Linux systems. This website uses cookies to ensure you get the best experience on our website. While the individual sensors may give instantaneous information in support of occupancy, a lack of sensor firing at a point in time is not necessarily an indication of an unoccupied home status, hence the need for a fusion framework. More than 100 million people use GitHub to discover, fork, and contribute to over 330 million projects. binary classification (room occupancy) from Temperature,Humidity,Light and CO2. occupancy was obtained from time stamped pictures that were taken every minute.

Multi-race Driver Behavior Collection Data. sign in The development of a suitable sensor fusion technique required significant effort in the context of this project, and the final algorithm utilizes isolation forests, convolutional neural networks, and spatiotemporal pattern networks for inferring occupancy based on the individual modalities. Timestamp format is consistent across all data-types and is given in YY-MM-DD HH:MM:SS format with 24-hour time. 7a,b, which were labeled as vacant at the thresholds used. In order to confirm that markers of human presence were still detectable in the processed audio data, we trained and tested audio classifiers on pre-labeled subsets of the collected audio data, starting with both unprocessed WAV files (referred to as P0 files) and CSV files that had gone through the processing steps described under Data Processing (referred to as P1 files). Machine-accessible metadata file describing the reported data: 10.6084/m9.figshare.14920131. The SBCs are attached to a battery, which is plugged into the wall, and serves as an uninterruptible power supply to provide temporary power in the case of a brief power outage (they have a seven hour capacity). Due to some difficulties with cell phones, a few of residents relied solely on the paper system in the end. The mean minimum and maximum temperatures in the area are 6C and 31C, as reported by the National Oceanic and Atmospheric Administration (NOAA) (https://psl.noaa.gov/boulder). Seidel, R., Apitzsch, A. However, simple cameras are easily deceived by photos. WebOccupancy Detection Computer Science Dataset 0 Overview Discussion 2 Homepage http://archive.ics.uci.edu/ml/datasets/Occupancy+Detection+ Description Three data sets are submitted, for training and testing. WebRoom occupancy detection is crucial for energy management systems. Because data could have been taken with one of two different systems (HPDred or HPDblack), the sensor hubs are referred to by the color of the on-site server (red or black). Because of size constraints, the images are organized with one hub per compressed file, while the other modalities contain all hubs in one compressed file. The fact that all homes had cameras facing the main entrance of the home made it simple to correct these cases after they were identified. Overall the labeling algorithm had good performance when it came to distinguishing people from pets. Audio files are named based on the beginning second of the file, and so the file with name 2019-10-18_002910_BS5_H5.csv was captured from 12:29:10 AM to 12:29:19 AM on October 18, 2019 in H6 on hub 5 (BS5). WebThe publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally identifiable In some cases this led to higher thresholds for occupancy being chosen in the cross-validation process, which led to lower specificity, along with lower PPV.

Candanedo, Vronique Feldheim. From these verified samples, we generated point estimates for: the probability of a truly occupied image being correctly identified (the sensitivity or true positive rate); the probability of a truly vacant image being correctly identified (the specificity or true negative rate); the probability of an image labeled as occupied being actually occupied (the positive predictive value or PPV); and the probability of an image labeled as vacant being actually vacant (the negative predictive value or NPV). The temperature and humidity sensor had more dropped points than the other environmental modalities, and the capture rate for this sensor was around 90%. In the last two decades, several authors have proposed different methods to render the sensed information into the grids, seeking to obtain computational efficiency or accurate environment modeling. Jacoby M, Tan SY, Henze G, Sarkar S. 2021. However, we believe that there is still significant value in the downsized images. Described in this section are all processes performed on the data before making it publicly available. OMS perceives the passengers in the car through the smart cockpit and identifies whether the behavior of the passengers is safe. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. The data from homes H1, H2, and H5 are all in one continuous piece per home, while data from H3, H4, and H6 are comprised of two continuous time-periods each. Overall, audio had a collection rate of 87%, and environmental readings a rate of 89% for the time periods released. WebAbout Dataset binary classification (room occupancy) from Temperature,Humidity,Light and CO2. The binary status reported has been verified, while the total number has not, and should be used as an estimate only. to use Codespaces. U.S. Energy Information Administration. See Table3 for a summary of the collection reliability, as broken down by modality, hub, and home. The scripts to reproduce exploratory figures. Note that the term server in this context refers to the SBC (sensor hub), and not the the on-site server mentioned above, which runs the VMs. This method first False positive cases, (i.e., when the classifier thinks someone is in the image but the ground truth says the home is vacant) may represent a mislabeled point. The goal was to cover all points of ingress and egress, as well as all hang-out zones. In one hub (BS2) in H6, audio was not captured at all, and in another (RS2 in H5) audio and environmental were not captured for a significant portion of the collection period. Energy and Buildings. Currently, rice panicle information is acquired with manual observation, which is inefficient and subjective. The proportion of dark images to total images each day was calculated for all hubs in all homes, as well as the proportion of missing images. van Kemenade H, 2021. python-pillow/pillow: (8.3.1). To ensure accuracy, ground truth occupancy was collected in two manners. This process works by fixing the pixel values at the edges of the image, then taking weighted averages of the inner pixels, in order to transform from the original size to the target size. How to Build a Occupancy Detection Dataset? Images were captured at a rate of 1 frame per second, while all environmental readings were captured every ten seconds. WebPeopleFinder Object Detection Dataset (v2, GoVap) by Shayaka 508 open source person images and annotations in multiple formats for training computer vision models. 10 for 24-hour samples of environmental data, along with occupancy. WebUCI Machine Learning Repository: Data Set View ALL Data Sets Check out the beta version of the new UCI Machine Learning Repository we are currently testing! (a) Raw waveform sampled at 8kHz. and S.S. conceived and oversaw the experiment. Each audio minute folder contains a maximum of six CSV files, each representing a processed ten-second audio clip from one hub, while each image minute folder contains a maximum of 60 images in PNG format. Please Environmental data processing made extensive use of the pandas package32, version 1.0.5. The system used in each home had to do with which was available at the time, and most of the presented data ended up being collected with HPDred. Additionally, radar imaging can assess body size to optimize airbag deployment depending on whether an adult or a child is in the seat, which would be more effective than existing weight-based seat sensor systems. Due to the increased data available from detection sensors, machine learning models can be created and used to detect room occupancy. This repository hosts the experimental measurements for the occupancy detection tasks. Terms Privacy 2021 Datatang. The climate in Boulder is temperate, with an average of 54cm of annual precipitation, in the form of rain in the summer and snow in the winter. In 2020, residential energy consumption accounted for 22% of the 98 PJ consumed through end-use sectors (primary energy use plus electricity purchased from the electric power sector) in the United States1, about 50% of which can be attributed to heating, ventilation, and air conditioning (HVAC) use2. and transmitted securely. As part of the IRB approval process, all subjects gave informed consent for the data to be collected and distributed after privacy preservation methods were applied. (a) H1: Main level of three-level home. Images include the counts for dark images, while % Dark gives the percentage of collected images that were counted as dark with respect to the total possible per day. The on-site server was needed because of the limited storage capacity of the SBCs. Datatang Figure3 compares four images from one hub, giving the average pixel value for each. Fisk, W. J., Faulkner, D. & Sullivan, D. P. Accuracy of CO2 sensors. Test subjects were recruited from the testing universitys department of architectural engineering graduate students and faculty in the front range of Colorado. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. The https:// ensures that you are connecting to the The released dataset is hosted on figshare25. For each hub, 100 images labeled occupied and 100 images labeled vacant were randomly sampled. The occupants cover a range of ages and relationships and consisted of couples, roommate households, and one family with adult children who were home during part of the testing duration. (c) Waveform after full wave rectification. The limited availability of data makes it difficult to compare the classification accuracy of residential occupancy detection algorithms. This operated through an if-this-then-that (IFTTT) software application that was installed on a users cellular phone. All image processing was done with the Python Image Library package (PIL)30 Image module, version 7.2.0. Performance of a k-nearest neighbors classifier on unprocessed audio (P0), and audio data as publicly available in the database (P1). Due to the presence of PII in the raw high-resolution data (audio and images), coupled with the fact that these were taken from private residences for an extended period of time, release of these modalities in a raw form is not possible. Learn more. Energy and Buildings. Learn more. If nothing happens, download Xcode and try again. Reliability of the environmental data collection rate (system performance) was fairly good, with higher than 95% capture rate for most modalities. Weboccupancy-detection My attempt on the UCI Occupancy Detection dataset using various methods. The ten-second sampling frequency of the environmental sensors was greater than would be necessary to capture dynamics such as temperature changes, however this high frequency was chosen to allow researchers the flexibility of choosing their own down-sampling methods, and to potentially capture occupancy related events such as lights being turned on. Summary of the completeness of data collected in each home. Datatang has developed series of OMS and DMS training datasets, covering a variety of application scenarios, such as driver & passenger behavior recognition, gesture sign in The two sets of images (those labeled occupied and those labeled vacant by the YOLO algorithm) were each randomly sampled in an attempt to get an equal number of each type. Testing of the sensors took place in the lab, prior to installation in the first home, to ensure that readings were stable and self consistent. At the end of the collection period, occupancy logs from the two methods (paper and digital) were reviewed, and any discrepancies or questionable entries were verified or reconciled with the occupants. Are you sure you want to create this branch? Datasets, Transforms and Models specific to Computer Vision I just copied the file and then called it. In each 10-second audio file, the signal was first mean shifted and then full-wave rectified. Images had very high collection reliability, and total image capture rate was 98% for the time period released. Note that these images are of one of the researchers and her partner, both of whom gave consent for their likeness to be used in this data descriptor. To solve this problem, we propose an improved Mask R-CNN combined with Otsu preprocessing for rice detection and segmentation. & Bernardino, A. Databases, Mechanical engineering, Energy supply and demand, Energy efficiency, Energy conservation. The sensor fusion design we developed is one of many possible, and the goal of publishing this dataset is to encourage other researchers to adopt different ones. STMicroelectronics. All data is collected with proper authorization with the person being collected, and customers can use it with confidence. All images in the labeled subsets, however, fell above the pixel value of 10 threshold. WebOccupancy grid maps are widely used as an environment model that allows the fusion of different range sensor technologies in real-time for robotics applications. Temperature, relative humidity, eCO2, TVOC, and light levels are all indoor measurements. G.H. In addition to the digital record, each home also had a paper backup that the occupants were required to sign-in and out of when they entered or exited the premises. WebAbstract. Webusetemperature,motionandsounddata(datasets are not public). Lists of dark images are stored in CSV files, organized by hub and by day. Additional IRB approval was sought and granted for public release of the dataset after the processing methods were finalized.

(c) Custom designed printed circuit board with sensors attached. Raw audio files were manually labeled as noisy if some sounds of human presence were audibly detectable (such as talking, movement, or cooking sounds) or quiet, if no sounds of human activity were heard. It is advised to execute each command one by one in case you find any errors/warnings about a missing package. 7d,e), however, for the most part, the algorithm was good at distinguishing people from pets. This dataset contains 5 features and a target variable: Temperature Humidity Light Carbon dioxide (CO2) Target Variable: 1-if there is chances of room occupancy. See Fig. National Library of Medicine OMS is to further improve the safety performance of the car from the perspective of monitoring passengers. Points show the mean prediction accuracy of the algorithm on a roughly balanced set of labeled images from each home, while the error bars give the standard deviations of all observations for the home. See Table2 for a summary of homes selected. Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the See Table6 for sensor model specifics. Abstract: Experimental data used for binary classification (room occupancy) from Temperature,Humidity,Light and CO2.

Please read the commented lines in the model development file. The sensor was supposed to report distance of the nearest object up to 4m. The actual range it can report, however, is subject to an internal mode selection and is heavily impacted by ambient light levels. Building occupancy detection through sensor belief networks. The YOLOv5 labeling algorithm proved to be very robust towards the rejection of pets. This Data Descriptor describes the system that was used to capture the information, the processing techniques applied to preserve the privacy of the occupants, and the final open-source dataset that is available to the public. Images with a probability above the cut-off were labeled as occupied, while all others were labeled as vacant. The sensor is calibrated prior to shipment, and the readings are reported by the sensor with respect to the calibration coefficient that is stored in on-board memory. Training and testing sets were created by aggregating data from all hubs in a home to create larger, more diverse sets. (a) System architecture, hardware components, and network connections of the HPDmobile data acquisition system. WebGain hands-on experience with drone data and modern analytical software needed to assess habitat changes, count animal populations, study animal health and behavior, and assess ecosystem relationships. Occupancy detection using Sensor data from UCI machine learning Data repository. Waymo is in a unique position to contribute to the research community with some of the largest and most diverse autonomous driving datasets ever released. (c), (d), and (e) are examples of false positives, where the images were labeled as occupied at the thresholds used (0.5, 0.3, and 0.6, respectively). Learn more. Sensors, clockwise from top right, are: camera, microphone, light, temperature/humidity, gas (CO2 and TVOC), and distance. Predictive control of indoor environment using occupant number detected by video data and co2 concentration. Keywords: occupancy estimation; environmental variables; enclosed spaces; indirect approach Graphical Abstract 1. Implicit sensing of building occupancy count with information and communication technology data sets. Despite the relative normalcy of the data collection periods, occupancy in the homes is rather high (ranging from 47% to 82% total time occupied). As necessary to preserve the privacy of the residents and remove personally identifiable information (PII), the images were further downsized, from 112112 pixels to 3232 pixels, using a bilinear interpolation process. These are reported in Table5, along with the numbers of actually occupied and actually vacant images sampled, and the cut-off threshold that was used for each hub. When transforming to dimensions smaller than the original, the result is an effectively blurred image. Carbon dioxide sensors are notoriously unreliable27, and while increases in the readings can be correlated with human presence in the room, the recorded values of CO2 may be higher than what actually occurred. To aid in retrieval of images from the on-site servers and later storage, the images were reduced to 112112 pixels and the brightness of each image was calculated, as defined by the average pixel value. Also reported are the point estimates for: True positive rate (TPR); True negative rate (TNR); Positive predictive value (PPV); and Negative predictive value (NPV). Ground truth for each home are stored in day-wise CSV file, with columns for the (validated) binary occupancy status, where 1 means the home was occupied and 0 means it was vacant, and the unverified total occupancy count (estimated number of people in the home at that time). Due to technical challenges encountered, a few of the homes testing periods were extended to allow for more uninterrupted data acquisition. Thus, data collection proceeded for up to eight weeks in some of the homes. Due to misclassifications by the algorithm, the actual number of occupied and vacant images varied for each hub. SciPy 1.0: Fundamental algorithms for scientific computing in Python. WebThe field of machine learning is changing rapidly. In light of recently introduced systems, such as Delta Controls O3 sensor hub24, a custom designed data acquisition system may not be necessary today. The time-lagged predictions were included to account for memory in the occupancy process, in an effort to avoid the very problematic false negative predictions, which mostly occurs at night when people are sleeping or reading. These labels were automatically generated using pre-trained detection models, and due to the enormous amount of data, the images have not been completely validated. Despite its better efficiency than voxel representation, it has difficulty describing the fine-grained 3D structure of a scene with a single plane. Audio processing was done with SciPy31 io module, version 1.5.0. Also collected and included in the dataset is ground truth occupancy information, which consists of binary (occupied/unoccupied) status, along with an estimated number of occupants in the house at a given time. The results are given in Fig. WebOccupancy Detection Data Set Download: Data Folder, Data Set Description. A tag already exists with the provided branch name. After training highly accurate image classifiers for use in the ARPA-E SENSOR project, these algorithms were applied to the full collected image sets to generate binary decisions on each image, declaring if the frame was occupied or vacant. The final distribution of noisy versus quiet files were roughly equal in each set, and a testing set was chosen randomly from shuffled data using a 70/30 train/test split. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch? Download: Data Folder, Data Set Description. Area monitored is the estimated percent of the total home area that was covered by the sensors. To achieve the desired higher accuracy, proposed OccupancySense model detects human presence and predicts indoor occupancy count by the fusion of Internet of Things (IoT) based indoor air quality (IAQ) data along with static and dynamic context data which is a unique approach in this domain. For the duration of the testing period in their home, every occupant was required to carry a cell phone with GPS location on them whenever they left the house. U.S. Energy Information Administration. The ECO dataset captures electricity consumption at one-second intervals. At present, from the technical perspective, the current industry mainly uses cameras, millimeter-wave radars, and pressure sensors to monitor passengers. This process is irreversible, and so the original details on the images are unrecoverable. It mainly includes radar-related multi-mode detection, segmentation, tracking, freespace space detection papers, datasets, projects, related docs Radar Occupancy Prediction With Lidar Supervision While Preserving Long-Range Sensing and Penetrating Capabilities: freespace generation: lidar & radar: For example, images and audio can both provide strong indications of human presence. 50 Types of Dynamic Gesture Recognition Data. Please First, minor processing was done to facilitate removal of data from the on-site servers. Luis M. Candanedo, Vronique Feldheim. Additionally, other indoor sensing modalities, which these datasets do not capture, are also desirable. The sensors used were chosen because of their ease of integration with the Raspberry Pi sensor hub. This paper describes development of a data acquisition system used to capture a The batteries also help enable the set-up of the system, as placement of sensor hubs can be determined by monitoring the camera output before power-cords are connected. The most supported model for detection and occupancy probabilities included additive effects of NOISE and EFFORT on detection and an intercept-only structure for We were able to accurately classify 95% of our test dataset containing high-quality recordings of 4-note calls. Keywords: Linear discriminant analysis, Classification and Regression Trees, Random forests, energy conservation in buildings, occupancy detection, GBM models. The authors declare no competing interests. Commercial data acquisition systems, such as the National Instruments CompactRio (CRIO), were initially considered, but the cost of these was prohibitive, especially when considering the addition of the modules necessary for wireless communication, thus we opted to design our own system. S.Y.T. Sun K, Zhao Q, Zou J. All authors reviewed the manuscript. Example of the data records available for one home. 2019. Thus, a dataset containing privacy preserved audio and images from homes is a novel contribution, and provides the building research community with additional datasets to train, test, and compare occupancy detection algorithms. Surprisingly, the model with temperature and light outperformed all the others, with an accuracy of 98%. VL53L1X: Time-of-Flight ranging sensor based on STs FlightSense technology.
