The embodiment of the invention provides a target tracking method and device. The method comprises the following steps: acquiring zoom coefficients and translation amounts of a first frame image and acurrent frame image of a tracking target; if it is judged that the second maximum value of the correlation operation of the current frame image and the first frame image is greater than the first preset threshold value; If the zoom coefficient is greater than the preset zoom coefficient and the translation amount difference between the current frame image and the previous frame image is less thana second preset threshold, obtaining the position and size of the tracking target in the current frame image based on the zoom coefficient and the translation amount, otherwise, taking the position and size of the tracking target of the previous frame image of the current frame image as the result of the current frame image. The position of the current frame of target and the size of the target are calculated according to the scaling coefficient and the translation amount, and a scaling calculation module is added, so that the target can be tracked more stably for a scaled scene; the performance is high, a target can be tracked more quickly, and the requirement of high frame rate is met; a confidence judgment strategy is added, and the drift condition is reduced.
Description
technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for object tracking. Background technique [0002] Object tracking is an important research direction in the field of vision. With the popularity of deep learning, performance has become more and more a limiting factor. Target tracking is a comprehensive application technology that integrates various technologies such as image processing, pattern recognition, artificial intelligence and automatic control, and is widely used in various fields. Target tracking refers to the detection, identification and tracking of moving targets or single-characteristic objects in the image sequence, and further processing by obtaining parameters such as the position and speed of the target or features such as the shape and color of the target, so as to realize Accurate tracking of moving objects. [0003] In the research field of target tracking,...
