Target identification and positioning method based on computer vision

The invention relates to a target identification and positioning method, in particular to a target identification and positioning method based on computer vision. The invention discloses a target identification and positioning method based on computer vision. The method structurally comprises an original image unit, a steady-state background unit, a transient-state background unit, a steady-statetarget unit and an activeness evaluation unit. Each unit executes the following steps: the original image unit: obtaining an original image; the steady-state background unit: acquiring a steady-statebackground; the transient background unit: acquiring a transient background; the steady-state target unit: acquiring a moving target; and the activeness evaluation unit: calculating an activeness weight. The method has the advantages: 1, the target in the visual field can be automatically subjected to screening recognition, and meanwhile, the position of the selected target in the visual field isoutput; 2, the method has t
