Keypoints number issues #30

Open YHaooo-4508 opened 1 year ago

YHaooo-4508 commented 1 year ago

Hello, I have currently created an SMPL model using demo. Besides I would like to use this SMPL model to obtain the coordinates of the 3Dkeypoints of the human body, but I encountered two issues：

  1. Smpl_output.body_pose shape is [23, 3, 3]. What does this mean? Is it related to the coordinates of the 3Dkeypoints
  2. Smpl_output.joints shape is [44, 3]. I thought SMPL joint number is 23 or 24 and I learned from the code that this is 25+19, and 25 is the openpose point. So what is 19. Besides I visualized and found that the points are outside the grid model. Why is this happening. image
  3. How can I get the coordinates of SMPL 23keypoints?

I would greatly appreciate it if you could spare some time to answer my questions

In issue2，‘Besides I visualized and found that the points are outside the grid model. Why is this happening.’ I forgot that i scaled the human mesh, and this is no problem. But I am still troubled by several other issues.
