Abstract

The embodiment of the application discloses a target tracking method, device, equipment and medium. The method comprises the following steps of acquiring a first video stream and performing the following data processing operations on each video frame in the first video stream of firstly detecting a candidate region in the current video frame according to the target detection model and the currentvideo frame; then according to the feature extraction model and the candidate region, extracting the depth features corresponding to each candidate region; then according to the depth feature corresponding to each candidate region and the depth feature of the target tracked in the previous video frame, calculating the feature similarity corresponding to each candidate region; finally determining the target tracked in the current video frame based on the feature similarity of each candidate region. By using the object detection model to detect the object in the current video frame range and tracking the object based on the depth feature, the method can effectively prevent the tracking drift or tracking object lost, and ensures the accuracy of target tracking.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular to an object tracking method, device, computer storage medium and equipment. Background technique [0002] Object tracking is one of the hotspots in the field of computer vision research. Object tracking has a wide range of applications in many fields such as video surveillance, navigation, military, human-computer interaction, virtual reality, and automatic driving. In simple terms, object tracking is to analyze and track a given object in a video to determine the exact location of the object in the video. [0003] Most of the existing target tracking methods are classic tracking methods based on the principle of correlation filter tracking. This tracking method updates the correlation filter according to the target area tracked in the previous frame of the video, and then uses the updated correlation filter to update the current target area. The target is tr...
