I am confused about the opencv camera calibration coordinate transformation. I used the example code to calibrate my camera, and I got this result:
When I use this camera matrix to multiply a point in camera coordinate system, say P = [50, 50, 1.35], the output result is too big which is impossible to be a pixel coordinate. What's is wrong here ? Did I miss something ?
