Abstract
The geometry between the horizontal and the vertical shifts of the lens to the CCD plane is introduced for the automatic vergence control of the parallel stereo camera. Under the condition that the disparity of stereo image remains constant, the horizontal shift of camera lens causing stereo disparity and the vertical shift causing focus have linear geometry. With this geometry, a simple auto-focusing algorithm is applied to the stereo camera lens for the vergence control of the parallel stereo camera.
