Abstract

The invention discloses a target tracking method based on Vibe and Camshift algorithms and relates to the field of computer visions. The method comprises the steps of firstly, detecting a moving target by use of an improved Vibe algorithm; then, tracking an external rectangle of an acquired target by use of Kalman filter to initialize a Camshift-tracking search window; and finally, performing target tracking by use of the Camshift, judging whether the shielding and the shielding degree exists in the target according to a target area obtained by tracking calculation and a Bhattacharyya coefficient, and performing corresponding target tracking according to the tracking shielding situation. The method is an automatic tracking method, the exact moving target is extracted, a ghost occurring inthe detection process is eliminated, the interference of a background color is eliminated for target tracking, the situation of deformation of the target can be adapted in the target tracking processand the correct tracking can be performed when the target is shielded.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a target tracking method based on Vibe and Camshift algorithms. Background technique [0002] Moving target tracking is widely used in military affairs, industrial production and daily life, such as military target tracking. The fully automatic moving target tracking includes two steps of moving target detection and target tracking. [0003] Among them, there are three kinds of moving target detection algorithms: optical flow method, frame difference method and background subtraction method. The optical flow method requires special hardware support, and the calculation is complex and computationally intensive, so it is generally seldom used. The principle of the inter-frame difference method is simple, and it is not sensitive to noise and light changes, but the target detection results are prone to holes. When the moving object changes slowly to fast motion, the background subtr...
