camera calibration without checkerboard

I have a picture with a 4x4 object of known siye inside. I do not know the cameraParams. Is it possible to estimate them using 4 points sampled from the image (imagepoints) and 4 points in world coordinates from the object (world points). I do not have a checkerboard.

Thanks

Hi Rupert,

may i know how you compute the imagepoint and world point from your object?
