[0090] In order to better understand the technical solutions of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0091] The principle block diagram of the present invention is as figure 1 Shown, the specific implementation steps of the present invention are as follows:
[0092] Step 1: Since the symmetry of pedestrians needs to be used in the improved algorithm, the first thing to do is to detect the position of the symmetry axis of the pedestrian target in the infrared image. The detection method of pedestrian symmetry axis is as follows:
[0093] 1) First use the saliency method to determine the approximate position of pedestrians. The present invention adopts Xiaodi Hou and JonathanHarel et al.
