The invention discloses a vehicle-road cooperation system and a road pedestrian detection method, and the system mainly comprises an image collection subsystem, a vehicle-mounted subsystem, an intelligent signal lamp subsystem, and an edge server subsystem, and the image collection subsystem, the vehicle-mounted subsystem, and the intelligent signal lamp subsystem provide data to the edge server subsystem. After the edge server subsystem processes the data, BSM and RSM data packets are sent to the vehicle-mounted subsystem, and SPAT data packets are sent to the intelligent signal lamp subsystem; wherein the image acquisition subsystem acquires and processes pedestrian images of an intersection, analyzes pedestrian flow, forms a data packet and sends the data packet to the edge server subsystem; the edge server subsystem processes an image based on an image processing technique using an improved edge detection algorithm, a machine learning algorithm, and a deep learning algorithm. According to the system, the advantages of each algorithm are fully utilized, the consumed time of pedestrian and vehicle identification procedures is shorter, the accuracy is higher, and the real-time performance and accuracy of information in the whole system are improved.
