Abstract

The invention discloses an object tracking method, an object tracking device, a storage medium and electronic equipment, and relates to the technical field of computer vision. The target tracking method includes: extracting the global features of the target area image; wherein, the target area image is the area image containing the target object predicted in the previous frame image of the current frame image; The global features of the current frame image are used for attention calibration, and the calibrated feature is used as the target calibration feature of the previous frame image; combined with the target calibration feature of the previous frame image, the target judgment feature of the current frame image is determined; the current frame image is determined. feature, determine the feature part that matches the target judgment feature from the global feature of the current frame image, and determine the image area corresponding to the feature part as the predicted area containing the target object in the current frame image, so as to realize the tracking of the target object . The present disclosure can improve the accuracy of target tracking.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular, to an object tracking method, an object tracking device, a storage medium, and electronic equipment. Background technique [0002] Visual Object Tracking (Visual Object Tracking, VOT), as an important research direction in the field of computer vision, can be widely used in video surveillance, human-computer interaction, unmanned driving, drones and other fields. [0003] At present, when determining the position of the target object in the current frame image, only the first frame image is often used for comparison. It can be considered that the first frame of image is the template used for tracking. However, the first frame of image does not clearly indicate the position of the target object, but only places the target object in the center of the picture. If the template contains non-target objects, and the non-target objects happen to appear in the center, ...
