I am tryinig to use Openpose Demo for 3D keypoint detection. I am usinig different brand of cameras. For 2D keypoint detection, it was successful to use my camera. Also, I connected 4 cameras to my computer, and Openpose demo worked well with each one of them. Problem is that Openpose cannot detect even one of my camera when I try 3D keypoint detection.
For the command: bin\OpenPoseDemo.exe --camera 0
For the command: bin\OpenPoseDemo.exe --3d --number_people_max 1
