The main issue of this task is find all necessary point and their world plane positions automatically. To reach this aim, we make some assumtions, such the X,Y plane checkerboard should be 7x6 points, Y,Z plane checkerboard should be 8x6 points, and X,Z plane checkerboard should be 6x8 points. In this way we … See more Assume we say ith point’s real world coordinate is [xi,yi,zi] and its camera image plane pixel locations is [pxi,pyi].According to Hall algorithm the camera model should be represented by 3x4 matrix A, whose … See more According to our test we took following R , T, and K values for left camera; For right camera, we took following output.
