METHOD AND DEVICE FOR MEASURING ABSOLUTE COORDINATE POSITION BY STEREO MATCHING METHOD

摘要

PROBLEM TO BE SOLVED: To easily measure an absolute coordinate position when it is difficult to correlate feature points with each other since an object to be measured has a repeated similar shape and even when there is an obstacle between a camera and the object to be measured.SOLUTION: The method for measuring an absolute coordinate position by a stereo matching method using a camera (left) Ofor photographing an object P to be measured and a camera (right) Ofreely movably in a predetermined direction to the camera (left) Oand photographing the object P to be measured comprises: positioning the camera (right) Oin front of the object P to be measured; positioning the camera (left) Oso as to satisfy a predetermined condition to be as a reference point; moving the camera (right) Oso as to satisfy a predetermined condition; and calculating an absolute coordinate position (X, Y, Z) of the object P to be measured on the basis of information on an image photographed by the camera (left) O.
