一种基于双线激光的三维测量方法
A 3D Measuring Method Based on Dual-beam Structured-lasers
摘要
Abstract
The 3D scanning system often encounters defects of reconstruction models during the scanning process, which is caused by the loss of scanning data due to the blocking of CCD' s viewing area by the object being measured. Aiming at this problem, this paper proposes an improved method, in which a laser is added at the CCD-centered symmetrical position to make the system enable to obtain two point clouds at two different angles. Then the two point clouds are stitched together to eliminate the defects of one single point cloud. Finally, distances of the upper, middle and lower parts of the object are measured respectively, as well as the distances of their 3D models. Meanwhile the mean squared error is calculated.关键词
