Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples, but not as a limitation of the present invention.
[0035] figure 1 It is a schematic flow chart of the optical marking-free three-dimensional human body motion capture method of the present invention. In this embodiment, the method includes the following parts:
[0036] 1. Use Zhang Zhengyou's calibration method to perform stereo calibration on the two cameras used in the system, and obtain the internal and external parameter matrices of the two cameras, as well as the rotation matrix and translation matrix between the two cameras;
[0037] 2. Using the positions of different joint points and their corresponding relationship with the real human body, and according to the actual direction of human body limbs, determine the number and connection relationship of the extracted 18 human joint points;
[0038] 3. Using the deep convolutional neural n...
