About dataset annotation #127

Open Followmeczx opened 4 months ago

Followmeczx commented 4 months ago

I looked at the annotated json files for the MSCOCO, MPII, Human36M datasets. I noticed that none of the camera parameters had extrinsic parameters for rotation and translation, but only intrinsic parameters for focal length and principal point. Why is that? What if I want to get the camera calibration parameters? Can you give me some advice

Hi, we use the weak perspective camera model. You can refer to this paper for more detail.
