I see the official document that the matlab r2019a version already supports estimating the camera projection matrix, the condition is that at least 6 sets of points in the same plane can be solved, but the problem is whether the camera matrix p can be inferred to obtain the camera intrinsics k, the rotation matrix r, and the translation. These coordinates can be transformed into normalized camera coordinates by multiplying by the inverse of k, thus obtaining points that lies on a plane at f=1 distance from. This perspective projection is modeled by the ideal pinhole.
