基于单目视觉几何构建的三维扫描系统
A 3D Scanning System Based on Monocular Vision Geometry Construction
摘要
Abstract
In order to construct a convenient and fast 3D scanner based on monocular vision , a high-precision monocular visual geometric projection of scene modeling method is proposed and a high-precision 3D scanning system is developed .Firstly, we ob-tain the coordinates of calibration points by image processing , and convert them into 3D camera coordinate system by the projec-tive transformation, and then construct the plane equation of Mesa and Base .Secondly, we calculate translation vectors through moving Mesa to obtain the translation vector , and get the laser plain equation by the camera center and the laser line which fell on the Mesa and Base.Finally, we extract the line center of laser light strip , and obtain the 3D point cloud data of object surface af-ter projection transformation and translation transform .Experiment results indicate that through the geometry projection transfor-mation method to construct the plane equation error is less than 0.2%, and the error of 3D scan results is less than 0.05 mm.关键词
