The invention provides a traffic flow detection method and device based on a video virtual coil. The method comprises the steps: configuring at least one virtual coil for detecting the traffic flow in a video image to obtain the position information and number information of each virtual coil; acquiring a real-time video stream, and decoding the real-time video stream to obtain a video frame image; processing the video frame image by using a vehicle detection tracking algorithm to obtain detection tracking information of each vehicle, wherein the detection tracking information of each vehicle comprises detection frame information and ID information of each vehicle; determining the current state of each virtual coil according to the detection tracking information of each vehicle and the position information of each virtual coil; wherein the current state of each virtual coil reflects the traffic flow of the road area corresponding to each virtual coil. According to the scheme, a geomagnetic coil does not need to be installed below the road surface, accurate detection of the road traffic flow is achieved through the video virtual coil, and the method has the advantages of being high in real-time performance, accurate in detection and low in cost.
