摘要/Abstract

摘要： 物体轮廓无接触测量与重构在工业中有广泛应用，然而目前市场上低端设备价格至少数万元。基于激光三角法搭建一套经济型三维无接触扫描仪，结合数据处理和几何重构等算法实现了对物体扫描、几何重建、测量功能。相比于对照的商用扫描仪，该系统在视野范围、数据质量、重构结果与测地距离估计方面都有一定优势。同时我们的算法能有效处理金属物体反光的问题，在极端情况下具有较好表现。实验结果表明，本文的无接触扫描平台流程适用于经济型扫描式数字化测量系统的实现与评估，可用于构建性价比较高的数字化测量系统。

Abstract: The non-contact measurement and reconstruction are widely used in industrial applications, however, the price of low-end equipment in the market is expensive. In this paper, an economical 3D non-contact scanner is built based on laser triangulation method, and the methods of object scanning, geometric reconstruction and measurement are implemented by combining data processing and geometric reconstruction. Compared with the comparative commercial scanners, the system in this paper has certain advantages in the range of view, data quality, reconstruction results and geodesic distance estimation. At the same time, our algorithm can effectively deal with the reflection of metal objects and has good performance in extreme cases. The experimental results show that the proposed non-contact scanning platform process is suitable for the implementation and evaluation of economical scanning digital measurement systems, and can be used to build cost-effective digital measurement systems.

Key words: laser scanning, image processing, point cloud reconstruction, geodesic distance
