2018-12-08 09:29:49 -0600 | marked best answer | Calculate robot coordinates from measured chessbaord corners ( hand-eye calibration) Hello guys, for my project I am trying to calibrate my depth camera with my robot-arm (hand-eye calibration). Therefore, I measured 8 corners of the cheassboard and got 8 pixel vectors and their corresponding robot 3D coordinates (using the gripper to point exactly at the corner). Then, I tried to calculate the transformation matrix. But the result is way off. Where's the mistake? Thank you very much! Edit: Added the camera matrix ------------------------------------- Edit ---------------------------------------------------------- I think I might be on to something. According to this: Stackoverflow I have to calculate the scaling factor. So i tried to do this in python: Looks like I am pretty close. But its still way off in the Y direction. Is this the correct approach? Thank you! |
