Abstract

The invention is applicable to the field of image processing and provides a moving target tracking method, a moving target tracking system and a moving target tracking terminal. The moving target tracking method comprises the following steps that: a current frame reference template is obtained, and a new target is detected on the current frame according to the current frame reference template; a target template is determined according to the detection result of the new target; a target template observation model is constructed according to the target template; a quasi target corresponding to the target template is sampled on the current frame, and a quasi target observation model is constructed according to the quasi target; the similarity of the target template observation model and the quasi target observation model is calculated, and the target position is predicted according to the similarity of the target template observation model and the quasi target observation model; and a target prediction observation model is constructed according to the target position, the similarity of the target template observation model and the target prediction observation model is calculated, and a next frame reference template is determined according to the similarity of the target template observation model and the target prediction observation model. With the adoption of the moving target tracking method, the moving target tracking system and the moving target tracking terminal, the tracking of a moving target in a complex background is real-timely and accurately realized.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a moving target tracking method, system and terminal. Background technique [0002] Moving target tracking is the basis of modern vision technology, and has important practical value in industrial process control, medical research, imaging guidance and other fields, and is widely used in military, security and transportation. [0003] In the prior art, there are many difficult problems in the tracking of moving objects in video images, mainly including: [0004] 1) Due to the translational or rotational movement of the target during the tracking process, the distance and viewing angle from the camera change, which will cause the scale change and deformation of the target image. These changes will cause the nonlinear change of the target image expression, resulting in tracking. failure; [0005] 2) Occlusion is also a major problem in motion tracking, that is, in the two frames b...
