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. del Blanco CR, Carballeira P, Jaureguizar F, Garca N. Robust people indoor localization with omnidirectional cameras using a grid of spatial-aware classifiers. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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. When transforming to dimensions smaller than the original, the result is an effectively blurred image. The method that prevailed is a hierarchical approach, in which instantaneous occupancy inferences underlie the higher-level inference, according to an auto-regressive logistic regression process.

Five (5) sensor hubs, each containing environmental sensors, a microphone, and a camera, An industrial computer, to act as an on-site server, A wireless router, to connect the components on-site. This ETHZ CVL RueMonge 2014 dataset used for 3D reconstruction and semantic mesh labelling for urban scene understanding. Research output: Contribution to journal Article Timestamps were simply rounded to the nearest 10-second increment, and any duplicates resulting from the process were dropped. Each home was to be tested for a consecutive four-week period. Datatang U.S. Energy Information Administration. The temperature and humidity sensor is a digital sensor that is built on a capacitive humidity sensor and thermistor. 2022-12-10 18:11:50.0, Euro NCAP announced that starting in 2022, it will start scoring child presence detection, a feature that detects that a child is left alone in a car and alerts the owner or emergency services to avoid death from heat stroke.. Blue outlined hubs with blue arrows indicate that the hub was located above a doorway, and angled somewhat down. The results show that feature selection can have a significant impact on prediction accuracy and other metrics when combined with a suitable classification model architecture. The paper proposes a decentralized and efficient solution for visual parking lot occupancy detection based on a deep Convolutional Neural Network (CNN) specifically designed for smart cameras. This solution is compared with state-of-the-art approaches using two visual datasets: PKLot, already existing in literature, and CNRPark+EXT. Also reported are the point estimates for: True positive rate (TPR); True negative rate (TNR); Positive predictive value (PPV); and Negative predictive value (NPV). Installed on the roof of the cockpit, it can sense all areas of the entire cockpit, detect targets, and perform high-precision classification and biometric monitoring of them. The data includes multiple age groups, multiple time periods and multiple races (Caucasian, Black, Indian). Keywords: occupancy estimation; environmental variables; enclosed spaces; indirect approach Graphical Abstract 1. (a) Average pixel brightness: 106. You signed in with another tab or window. Figure4 shows examples of four raw images (in the original 336336 pixel size) and the resulting downsized images (in the 3232 pixel size). In terms of device, binocular cameras of RGB and infrared channels were applied. It is understandable, however, why no datasets containing images and audio exist, as privacy concerns make capturing and publishing these data types difficult22. Due to the increased data available from detection sensors, machine learning models can be created and used to detect room occupancy. Data Set: 10.17632/kjgrct2yn3.3. A tag already exists with the provided branch name. Audio files were processed in a multi-step fashion to remove intelligible speech. G.H. 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. An official website of the United States government. (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). Sensors, clockwise from top right, are: camera, microphone, light, temperature/humidity, gas (CO2 and TVOC), and distance. 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. OMS generally uses camera equipment to realize the perception of passengers through AI algorithms. Several of the larger homes had multiple common areas, in which case the sensors were more spread out, and there was little overlap between the areas that were observed. Caleb Sangogboye, F., Jia, R., Hong, T., Spanos, C. & Baun Kjrgaard, M. A framework for privacy-preserving data publishing with enhanced utility for cyber-physical systems. In the process of consolidating the environmental readings, placeholder timestamps were generated for missing readings, and so each day-wise CSV contains exactly 8,640 rows of data (plus a header row), although some of the entries are empty. Audio processing was done with SciPy31 io module, version 1.5.0. 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). 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. There may be small variations in the reported accuracy. 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. The results show that while the predictive capabilities of the processed data are slightly lower than the raw counterpart, a simple model is still able to detect human presence most of the time. The pandas development team. All authors reviewed the manuscript. Despite its better efficiency than voxel representation, it has difficulty describing the fine-grained 3D structure of a scene with a single plane. To ensure accuracy, ground truth occupancy was collected in two manners. (b) Average pixel brightness: 43. While many datasets exist for the use of object (person) detection, person recognition, and people counting in commercial spaces1921, the authors are aware of no publicly available datasets which capture these modalities for residential spaces. This dataset adds to a very small body of existing data, with applications to energy efficiency and indoor environmental quality. (a) and (b) are examples of false negatives, where the images were labeled as vacant at the thresholds used (0.3 and 0.4, respectively). Experimental results show that PIoTR can achieve an average of 91% in occupancy detection (coarse sensing) and 91.3% in activity recognition (fine-grained sensing). 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. Since higher resolution did have significantly better performance, the ground truth labeling was performed on the larger sizes (112112), instead of the 3232 sizes that are released in the database. National Library of Medicine WebAbout Dataset binary classification (room occupancy) from Temperature,Humidity,Light and CO2. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. If nothing happens, download GitHub Desktop and try again. For example, images and audio can both provide strong indications of human presence. Luis M. Candanedo, Vronique Feldheim. Review of occupancy sensing systems and occupancy modeling methodologies for the application in institutional buildings. Are you sure you want to create this branch? Newsletter RC2022. Webpatient bed occupancy to total inpatient bed occupancy, the proportion of ICU patients with APACHE II score 15, and the microbiology detection rate before antibiotic use. 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: Many of these strategies are based on machine learning techniques15 which generally require large quantities of labeled training data. 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. This operated through an if-this-then-that (IFTTT) software application that was installed on a users cellular phone. (c) Waveform after full wave rectification. A tag already exists with the provided branch name. Time series data related to occupancy were captured over the course of one-year from six different residences in Boulder, Colorado. 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. 2, 28.02.2020, p. 296-302. The publicly available dataset includes: grayscale images at 32-by-32 pixels, captured every second; audio files, which have undergone processing to remove personally WebPeopleFinder Object Detection Dataset (v2, GoVap) by Shayaka 508 open source person images and annotations in multiple formats for training computer vision models. The homes tested consisted of stand-alone single family homes and apartments in both large and small complexes. Energy and Buildings. Days refers to the number of days of data that were released from the home, while % Occ refers to the percentage of time the home was occupied by at least one person (for the days released). In The 2nd Workshop on 8600 Rockville Pike With the exception of H2, the timestamps of these dark images were recorded in text files and included in the final dataset, so that dark images can be disambiguated from those that are missing due to system malfunction. Kleiminger, W., Beckel, C. & Santini, S. Household occupancy monitoring using electricity meters. Leave your e-mail, we will get in touch with you soon. Next, processing to validate the data and check for completeness was performed. Received 2021 Apr 8; Accepted 2021 Aug 30. 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. Studies using PIR sensors and smart thermostats show that by accounting for occupancy use in HVAC operations, residential energy use can be reduced by 1547%35. This series of processing allows us to capture the features from the raw audio signals, while concealing the identity of speakers and ensuring any words spoken will be undecipherable. Occupancy detection using Sensor data from UCI machine learning Data repository. 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. Jacoby M, Tan SY, Mosiman C. 2021. mhsjacoby/HPDmobile: v1.0.1-alpha. Luis M. Candanedo, Vronique Feldheim. First, a geo-fence was deployed for all test homes. ), mobility sensors (i.e., passive infrared (PIR) sensors collecting mobility data) smart meters (i.e., energy consumption footprints) or cameras (i.e., visual In terms of device, binocular cameras of RGB and infrared channels were applied. To generate the different image sizes, the 112112 images were either downsized using bilinear interpolation, or up-sized by padding with a white border, to generate the desired image size. The hda+data set for research on fully automated re-identification systems. (eh) Same images, downsized to 3232 pixels. Full Paper Link: https://doi.org/10.1109/IC4ME253898.2021.9768582. 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: The data acquisition system, coined the mobile human presence detection (HPDmobile) system, was deployed in six homes for a minimum duration of one month each, and captured all modalities from at least four different locations concurrently inside each home. to use Codespaces. Volume 112, 15 January 2016, Pages 28-39. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. Install all the packages dependencies before trying to train and test the models. Verification of the ground truth was performed by using the image detection algorithms developed by the team. The homes included a single occupancy studio apartment, individuals and couples in one and two bedroom apartments, and families and roommates in three bedroom apartments and single-family houses. Datatang has developed series of OMS and DMS training datasets, covering a variety of application scenarios, such as driver & passenger behavior recognition, gesture to use Codespaces. Environmental data are stored in CSV files, with one days readings from a single hub in each CSV. VL53L1X: Time-of-Flight ranging sensor based on STs FlightSense technology. The project was part of the Saving Energy Nationwide in Structures with Occupancy Recognition (SENSOR) program, which was launched in 2017 to develop user-transparent sensor systems that accurately quantify human presence to dramatically reduce energy use in commercial and residential buildings23. has developed series of OMS and DMS training datasets, covering a variety of application scenarios, such as driver & passenger behavior recognition, gesture control, facial recognition and etc. This outperforms most of the traditional machine learning models. This paper describes development of a data acquisition system used to capture a range of occupancy related modalities from single-family residences, along with the dataset that was generated. privacy policy. WebKe et al. Machine-accessible metadata file describing the reported data: 10.6084/m9.figshare.14920131. Some homes had higher instances of false positives involving pets (see Fig. The scripts to reproduce exploratory figures. 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). Our team is specifically focused on residential buildings and we are using the captured data to inform the development of machine learning algorithms along with novel RFID-based wireless and battery-free hardware for occupancy detection. Rice yield is closely related to the number and proportional area of rice panicles. In addition to the environmental sensors mentioned, a distance sensor that uses time-of-flight technology was also included in the sensor hub. (b) H2: Full apartment layout. Currently, rice panicle information is acquired with manual observation, which is inefficient and subjective. (a) H1: Main level of three-level home. In . Luis M. Candanedo, Vronique Feldheim. 6 for a diagram of the folder structure with example folders and files. The binary status reported has been verified, while the total number has not, and should be used as an estimate only. 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. The results are given in Fig. (b) Waveform after applying a mean shift. Even though there are publicly If the time-point truly was mislabeled, the researchers attempted to figure out why (usually the recording of entrance or exit was off by a few minutes), and the ground truth was modified. The temperature and humidity sensor had more dropped points than the other environmental modalities, and the capture rate for this sensor was around 90%. 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. Please cite the following publication: Accurate occupancy detection of an office room from light, temperature, humidity and CO2 measurements using statistical learning models. The illuminance sensor uses a broadband photodiode and infrared photodiode, and performs on-board conversion of the analog signal to a digital signal, meant to approximate the human eye response to the light level. How to Build a Occupancy Detection Dataset? 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. Work fast with our official CLI. Use Git or checkout with SVN using the web URL. 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. All code used to collect, process, and validate the data was written in Python and is available for download29 (https://github.com/mhsjacoby/HPDmobile). (seven weeks, asynchronous video lectures and assessments, plus six 1.5 hour synchronous sessions Thursdays from 7-8:30pm ET) Interested researchers should contact the corresponding author for this data. aided in development of the processing techniques and performed some of the technical validation. The dataset has camera-based occupant count measurements as well as proxy virtual sensing from the WiFi-connected device count. R, Rstudio, Caret, ggplot2. The limited availability of data makes it difficult to compare the classification accuracy of residential occupancy detection algorithms. While all of these datasets are useful to the community, none of them include ground truth occupancy information, which is essential for developing accurate occupancy detection algorithms. 0-No chances of room occupancy Inspiration Classification was done using a k-nearest neighbors (k-NN) algorithm. SMOTE was used to counteract the dataset's class imbalance. The images from these times were flagged and inspected by a researcher. Energy and Buildings. Overall, audio had a collection rate of 87%, and environmental readings a rate of 89% for the time periods released. HPDmobile: A High-Fidelity Residential Building Occupancy Detection Dataset. (a) System architecture, hardware components, and network connections of the HPDmobile data acquisition system. See Fig. WebDatasets, depth data, human detection, occupancy estimation ACM Reference Format: Fabricio Flores, Sirajum Munir, Matias Quintana, Anand Krishnan Prakash, and Mario Bergs.
