HI about 1 and 2 ,
About the first one what is marked as True,The intrinsic parameter matrix is not typically converted camera coordinates into pixel coordinates and not image corresponds to pixels?
Secondly, the camera projection matrix represents the mapping from 3D points in the world to 2D points in an image. It is the product of the intrinsic and extrinsic matrices, and it indeed has 12 elements, so is it representing 12 degrees of freedom? according the answers is it False
