Multi-target real-time tracking method and device based on AR interactive game scene

The embodiment of the invention discloses a multi-target real-time tracking method and device based on an AR interactive game scene, and the method comprises the steps: carrying out the target association of a same target point in different target frames in a to-be-detected video stream with a plurality of target points; for at least one target point, tracking by using a multi-target tracking algorithm according to the position information of the target point in the previous frame of the target frame and the similarity of the target point in the next frame of the target frame; and under the condition of determining that the target is lost in the next frame, storing the position information, the feature information and the associated information of the target point in the previous frame, and marking the loss state in the previous frame. According to the method, the current state of the lost person can be timely stored and marked, so that similarity matching with the lost target can be carried out when the appe
