AQPDCITY

AQPDCITY数据集是由北京工业大学信息科学与技术学院创建，包含1500张在大城市不同地点和时间拍摄的照片，用于基于图片的PM监测。数据集涵盖了广场、寺庙、湖泊、街道等多种场景，照片分辨率从500×261到978×550不等。创建过程中，使用智能手机和单反相机等设备进行拍摄，并通过中国国家环境监测中心的历史记录获取每张照片的PM值。该数据集主要用于解决城市空气质量监测问题，特别是在PM浓度实时监测方面。

The AQPDCITY dataset was created by the School of Information Science and Technology, Beijing University of Technology. It consists of 1500 photographs taken at various locations and times across major urban areas, and is intended for image-based PM monitoring. The dataset covers diverse scenarios including squares, temples, lakes, streets and more, with image resolutions ranging from 500×261 to 978×550. During its development, photos were captured using devices such as smartphones and DSLR cameras, and the PM values corresponding to each photograph were obtained from the historical records of the China National Environmental Monitoring Centre. This dataset is primarily designed to solve urban air quality monitoring issues, with a particular emphasis on real-time PM concentration monitoring.
