Detecting Snow Covered Solar Panels Dataset

Data Owner: Jia Ying Lin, Costin Ograda-Bratu and S. Keshav Data Description: There are many anomalies that may affect a solar panel’s power production, including cloudiness, snow, dust, and shadows. Images of the solar panels are taken as input to detect snow, since it can be easily identified through images. This dataset contains a set of measurements from a solar installation on top of the ERC building at the University of Waterloo, and some photos of the system which could allow image recognition to identify snow on the panels. Data Size: The dataset is 172.2 MB in total. Data Field Description: In the Images folder, there are three folders: no_snow, partial, and all_snow containing images of the solar panels with no snow on it, partially covered by snow, and completely covered in snow respectively. Every jpg file is named with the timestamp that the image is taken. Images are taken at January 26th, 27th, 28th, February 2nd, 3rd, 28th, and March 1st, 2nd, 21st, 22nd, 23rd, 24th, 25th of 2019. In the Power_Measurements folder, each file is named after the date when the measurements are taken. Each entry consists of the timestamp, battery voltage and charging current. Power measurements are collected from February 27th 2019 to July 22nd 2019. Funding: Cisco Systems and the Natural Science and Engineering Research Council of Canada (NSERC).

数据说明：诸多异常因素可能影响太阳能光伏板的发电效能，包括云层遮蔽、积雪、灰尘与阴影。鉴于积雪可通过图像直观识别，本数据集以太阳能光伏板实拍图像作为输入，用于积雪检测任务。本数据集包含加拿大滑铁卢大学ERC大楼顶部太阳能装置的多组实测数据，以及该系统的多张实拍照片，可支持基于图像识别的光伏板积雪检测研究。
数据规模：本数据集总容量为172.2 MB。
数据字段说明：在Images文件夹中包含三个子文件夹：no_snow、partial与all_snow，分别存储无积雪、部分被积雪覆盖以及完全被积雪覆盖的太阳能光伏板图像。所有JPG格式图像均以拍摄时的时间戳命名。图像拍摄日期为2019年1月26日、27日、28日，2019年2月2日、3日、28日，以及2019年3月1日、2日、21日、22日、23日、24日、25日。
在Power_Measurements文件夹中，每个文件均以测量数据的采集日期命名。每条记录包含时间戳、电池电压与充电电流三项信息。电力实测数据的采集时段为2019年2月27日至2019年7月22日。
