Abstract
A construction site safety monitoring system based on computer vision is provided. It includes a data acquisition system for collecting video information of personnel and operation platforms on construction site in real time; an information processing system for detecting and distinguishing the personnel and the operation platforms in the video information, intercepting personnel feature images and video of tilted operation platform whose personnel facial temperature and inclination angles after calculation are greater than or equal to preset values as a personnel safety incident and a platform safety incident respectively; and a terminal reminder system for receiving information of at least one the personnel safety incident and the platform safety incidents and providing a reminder. It can more accurately capture feature information of personnel and operation platform, analyze and calculate the feature information, realize personnel temperature measurement and detect the safety of operation platform, and has a wider application range.
