Problems solved by technology

[0002] The tracking of moving objects has always been a research hotspot in the field of scientific research. There are many factors that affect the effect of object tracking in real life. At present, most of the object tracking algorithms can only be applied in specific environments. Traditional moving object tracking algorithms The lack of biological intelligence cannot adapt to complex environmental changes, making the tracking effect unsatisfactory, and there are great limitations in use. It has always been a challenge in the direction of target tracking to achieve the effect of biological tracking targets.

Embodiment Construction

[0016] 1. Construct the target template, and convert the biological probability characteristic coefficient W of the target into the target probability map. In the target probability map, we can clearly find the target features. Use the target probability map to calculate the center of gravity position of the target probability map,

[0017] That is, the center of the maximum probability in the target template. The coordinate position of the x pixel in the target template area is {x i * ,i=1...n},

[0018] The target pixel probability value is

[0019] Amount of target probability:

[0020]

[0021] Target Probability Center:

[0022]

[0023] Target biological probability characteristic coefficient:

[0024]

[0025] 2. Build candidate target templates. The candidate target template is similar to the target template, that is, select the target position area y of the previous frame in the next frame, and the coordinate position of the pixel point in the area ...

Abstract

The invention discloses a method of target tracking based on bionic technology. The invention uses the bionic technology in the process of tracking the target, the eye movement mode and search strategy and five visual characteristics of the biological visual system, including light and dark characteristics, color characteristics, Sensitivity characteristics, visual residual and memory characteristics, use these characteristics to change the characteristics of the target to design a search algorithm suitable for target tracking. It includes three steps: constructing target templates, constructing candidate target templates, and updating target templates. The target tracking method based on bionic technology combines the intelligent processing method of biological visual characteristics on the target, and proposes a method of replacing the color feature center of gravity with the maximum probability center of gravity.
