Embodiment 1
[0043] Example 1, such as image 3 As shown, the method of 3D human pose estimation based on video stream is as follows:
[0044] For the first frame of the video, 1) input the two-dimensional image of the current frame, use the hourglass network module to extract the two-dimensional posture of the human body, and generate a heat map of the two-dimensional joint points of the human body in the first frame; The heat map is output to the 3D joint point inference module, and the 2D to 3D spatial mapping is performed to generate the 3D joint point heat map of the human body;
[0045] In the second frame of the video, 1) input the two-dimensional image of the current frame, and use the shallow neural network module to generate a shallow image; Input it to the LSTM module to generate a deep feature map; 3) The deep image feature map generated by the current frame is output to the residual module to generate the heat map of the two-dimensional joint points of the human body in the c...
