if I have a camera that has known interior parameters. is it possible to determine camera orientation (Yaw, pitch, roll) against an imaged rectangle without knowing the rectangle's size and width/length ratio?

I found a paper titled " determining camera parameters from the perspective projection of a rectangle" at here but it turned out i cannot get correct answers using their methods. I tried openCV's function "solvePnP" but that seems to need to know the width and length ratio of the rectangle, or it needs to shape to be a square....

i searched google for a while but could not figure out how to do this.a solid method
