The Orientation And Measure Of Dimensional Point Based On Stereo Projection

Following the development of computer technology, Graphics has wider developable space than past times. Especially the application field, has been more and more wide, and also the application frequency has been bigger. Thereinto, CAD/CAM is the most abroad and active area that the Computer Graphics has been used, one of the important study fields in CAD is three-dimensional rebuild based on planar engineering-drawing. Three-dimensional rebuild is picking-up three-dimensional information from planar image, and then by classify, integration to build solid in space, resume body's point, line, plane and their logical relation.The focus idea of the object that we studied is based on stereo projection, carrying out the space points' exact position and the distance between them. The main method is using a couple of camera to simulate person's eyes, by the left and right images to achieve the result of dimensional points' position and distance's measurement.To achieve this aim, there are two work, camera calibration and correlated points matching, must be accomplished at first. Using the Vision Sensor that designed by ourselves, we get the inside and outside parameters of the camera we used, and compare to formerly study model, the sensor we designed is more concise. Image matching is also the important and difficulty problem, this paper puts forward a complex matching method contain module matching and epipolar line restricting, and simulated this arithmetic by Matlab software.To the end of this article, we validated the idea by experiment, compare and analyses this theoretic' merit and defect, and bring forward the further study of this object. At the last, a suggestion to further study about the object is put forward, hopefully helpful to those who bend on this useful academic corner.Written By WANG Fu-Jun Directed By Professor YOU Bu-Dong...
