Abstract :
This paper presented an improved self-calibrate method based on active vision system. The camera was controlled to move directly in a plane and rotated around the x-axis in the camera coordinates in five times or more, then we calibrated the camera by the epipoles in the images. This method improved the accuracy and robust of the epipoles, compared with other method.
