A method of acquiring 3-D data of an object from stereo images

A method of acquiring 3-D data of an object via binocular technique is presented in this paper. It attempts to improve the accuracy of 3-D measurement of the passive technique and the main feature of this method are: 1) accurate (subpixel) location of the noisy image edge segments by parameterization; 2) using generalized cones for 3-D measurement with an accuracy beyond resolution limit of the digital sensor.
