THE METHOD OF DISTANCE MEASUREMENT USING STEREO CAMERA

The paper proposes the method of using image processing to determine the distances
between autonomous vehicle, where stereo vision is installed, and the observed objects. Purposely, a stereo camera Minoru is used. The stereo camera uses two different 2D images, which are the two horizontally different views of the same object, to get the depth information. The complete process includes of three steps which are image acquisition, camera calibration and camera rectification. The accuracy of measurement depends on the image resolution, the distance between the two cameras, and the characteristics of the image. The result of paper will also be presented to prove the relationship between the accuracy and the resolution of stereo images
