2017-06-25 12:28:47 -0600 | asked a question | Real World Coordinate of Rotary table in Stereo Calibration I have implemented stereo camera calibration and I can get the extrinsic and intrinsic camera parameter. For calibration I have captured the calibration board with 6-DOF. But now calibration board is mounted on the rotary table and I need to calculate the position (XZ) of rotary table respect to the origin point which is camera 0. My idea to get the XZ position of rotary table is: 1- capturing some calibration board images by rotating the table 2- calculating the normal vector of calibration board 3- finding the cross sections of those normal vectors (at least two) My question is how can I calculate the normal vector of calibration board? or maybe someone has better solution to get the world coordinate of the rotary table. I googled it but couldn't find something relevant. |
