The present invention provides a traffic light control method with edge computing and ambient edge intelligence, comprising a data center and an edge computing component. The data center component first uses a service discovery module to discover available devices that can serve as edge servers and converts the discovered devices into edge servers. After a camera captures a video frame, each frame is transmitted via two paths: one for local detection and the other for remote detection. The edge computing component performs initial object detection on the local device and extracts objects that cross the boundary. The data center component captures video using a surveillance camera, and the client sends the video frames to the corresponding edge device via an established WiFi connection. The edge computing component's edge server decodes data in a receiving queue and then sends the objects to the client. The data center client integrates the results of local and remote object detection to derive a final result, which is then used to control the traffic light.
