Abstract

The invention discloses a moving target tracking method based on Mean Shift and block matching. The moving target tracking method is characterized by comprising the following steps of: I, determining a primary target model and a secondary target model; II, solving a secondary target model position in a current frame by utilizing a Mean Shift algorithm; and III, obtaining an optimal position of the primary target model in the secondary target model range by utilizing the block matching according to the secondary target model position obtained in the step II. According to the moving target tracking method, the tracking accuracy of the Mean Shift algorithm is improved, some conditions which can not be tracked by the Mean Shift algorithm are tracked accurately; and the moving target tracking method based on the Mean Shift and the block matching can be applied to the fields, such as intelligent video monitoring systems, man-machine interaction, robot visual navigation, image compression, intelligent traffic systems, military guidance and navigation and the like.
