cvFindExtrinsicCameraParams2 strange behaviour
I use cvFindExtrinsicCameraParams2 function for determinate rotation matrix and translation vector.
I have a strange situation.
When my pattern close to camera, everything is OK, but when it so far from camera, i have (look at picture) trouble.
It appears when i look at the pattern from angle 90* between optical axis and marker's plane
My question is why this appears and how can i solve it?
