一种无标记点三维点云自动拼接技术
AN UNMARKED 3D POINT CLOUD AUTOMATIC REGISTRATION TECHNOLOGY
摘要
Abstract
The phase projection and binocular vision based 3D optical measurement system is widely applied to many fields. Due to the limitation of projection light measurement system's single measurement range size along with there being a drawback that it requires time and again pastes of circular markers on the surface when measuring a large object, an unmarked automatic registration technology based on SIFT is explored. The technology uses SIFT method to gain feature points for twice measurements;next,by combining RANSAC, works out the matching relation among image feature points; then, according to the corresponding relation between the image feature points in the stereo match and the 3D point cloud,maps the 2D feature points' corresponding relation onto the 3D point cloud;finally depends on SVD algorithm to solve for the rotation and translation matrix to realize registration. Experiments prove that the method can avoid pasting markers on the measured object;as a result,it can quickly and accurately achieve automatic registration.关键词
