Safety helmet detection system for intelligent construction site

The invention provides a safety helmet detection system for an intelligent construction site. The safety helmet detection system comprises a server and a camera in communication connection with the server, the camera is used for acquiring a second video frame of the working face and transmitting the second video frame to the server, and the server detects a pedestrian bounding box from the second video frame and acquires a rectangular image area Qi in the corresponding pedestrian bounding box according to a stored position-height mapping relation (TY, TH); and when it is detected that no safety helmet exists in the Qi, giving an alarm. In a complex construction site, whether the helmet is worn on the head or not is judged through a mature pedestrian detection technology, and interference of the environment on helmet judgment is reduced. 本发明提供了一种用于智慧工地的安全帽检测系统，包括服务器、与服务器通信连接的摄像头；摄像头用于获取工作面的第二视频帧，并传输给服务器，服务器从第二视频帧中检测行人包围盒，并根据存储的位置-高度映射关系（TY，TH）获取对应行人包围盒中的矩形图像区域Qi；当检测到Qi中不存在安全帽时，进行报警。在复杂的施工现场，通过成熟的行人检测技术判断是否头戴安全
