| 摘 要： | 大多数现有的主流结构光测量装置在被测物体的表面上投射单条激光,通过移动装置实现物体表面的扫描重建。为了实现物体表面的在线快速重建,将多线结构光和双目立体视觉理论相结合,设计了一种新的三维测量方法。提出了一种结合形态滤波和Zhang-Suen细化算法的光条骨架提取方法和基于光条序列关系的光条匹配算法,并通过极线约束实现光条上特征点的精确匹配。通过实验验证了方法的有效性,相对误差在3%以内。

| Abstract: | Most existing mainstream structured light measuring devices project a single laser on the surface of the object to be measured,then,the reconstruction of the surface of the object is finished by the moving device.To do the online measurement of the system,the method is used with multi-line structured light and binocular stereo vision theory to design a new online three-dimensional measurement method.A light strip skeleton extraction method based on morphological filtering and Zhang-Suen thinning algorithm and a light strip matching algorithm based on light strip sequence relationship are proposed.Then,the polar line constraint is used to achieve an exact matching of the feature points on the strip.The effectiveness of this method is verified in the experiment.The relative error is with in 3%. |
