We propose a new method which compensates optical axes misalignment along with stereo camera zooming automatically. Optical axes misalignment is modeled as image sensor center translation from the lens center. To match the image points of left and right image, right camera translation and rotation equation is devised. By using these equations we can easily get the rig calibration value. Then, we can compensate optical axes misalignment by saving and applying this rig calibration information when we change the zoom of stereo camera. The explanation of the proposed method and devised equation will be provided. And experimental verification results using stereo camera rig will be presented in the paper.
