[0030] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0031] The whole process of the present invention is: firstly, a pedestrian image in the detection area is acquired by a vertically placed camera, a background model is performed on the acquired depth image, and then a simulated random dripping operation is performed according to the acquired foreground size, and each point is based on The size of the surrounding points determines its running direction and staying position. Finally, the gathering place of all the points is counted, and the area size filtering is performed to obtain the number of people in the scene.
[0032] Such as figure 1 with figure 2 As shown: the human head detection method of the present invention includes the following steps, respectively:
[0033] a. Set up a vertically distributed camera 1 and an active light source matching the camera 1, and use the camera 1 to obtain a depth image of the ...
