Embodiment Construction
[0058] Please also see Figure 1 to Figure 6 , the present invention provides a kind of posture recognition method based on near-infrared TOF camera depth information, and it comprises the following steps:
[0059] S1: Get a depth image. In this embodiment, the depth image is acquired by a near-infrared TOF camera SR4000.
[0060] S2: Extract the human target from the depth image, as well as the centroid and skeleton of the human target. Specifically, the following steps are included:
[0061] S21: sequentially perform background difference processing and image binarization processing on the depth image to obtain a target binary image;
[0062] S22: Perform hole filling, opening operation processing, and connected domain marking on the target binary image in sequence to obtain the centroid of the connected domain;
[0063] S23: performing zhang fast parallel thinning operation on the target binary image to realize the extraction of the human target skeleton and its coordin...
