【Abstract】 This paper presents a stereo analysis technique for determining the 3-D co-orainates of an object.It includes:(1)camera calibration,(2)stereo image acquisition,(3)image preprocessing,(4)stereo matching,and(5)computation of the 3-D coor-dinates of sample points from an object.A simple and efficient method of camera cali-bration is proposed.The least square method and the Lagrange multiplier method aregiven for computing the 3-D coordinates.Experimental results indicate that satisfac-tory measurement accuracy has been obtained.更多还原
