The accuracy of 3D measurement using stereo method depends strongly on the accuracy of calibration. But, its very difficult to keep optical systems exactly the same with the calibration condition. For this reason, the measuring system that uses stereo method needs calibration work again and again. To solve this problem, we proposed “relative stereo method” so far. Relative stereo method shows an impressively high accuracy in relative distance, and has a good tolerance to calibration error. However, relative stereo method needs enough length between the camera and measuring objects, so relative stereo method has errors in close range measuring. Therefore, this paper presents a new 3D measurement method which solves the problem of relative stereo method and has a good tolerance to calibration error.
