随着轨道交通行业的发展，对轨道车辆的制造要求越来越高。轨道车辆内饰件装配是轨道车辆生产的重要质量控制项点。采用基于多视相移框架的结构光快速三维测量技术，可以将多视约束与相移原理有机结合，解相完成后每个像素可以独立地进行立体匹配与三维重构，无需相位展开过程，从而快速重构出密集三维轮廓数据。相比现有的结构光测量技术，该方法使测量速度与相机图像采集的速度一致，能实现任意复杂形状物体的全时间分辨率、全空间分辨率的快速三维测量。%With the booming development of rail transit industry,there is more requirement to the manufacturing of rail-way vehicles.The assembly of interiors plays an important role of deciding the quality of railway vehicles production.The rapid three-dimensional measurement technology of structured light based on multi-view phase-shift framework is used.This technique combined multi-view constraint with phase-shift and each pixel can explore its corresponding point independently only in the wrapped phase-map and reconstruct a 3D point in space,so arbitrary shape including the discontinuous surfaces or step-like surfaces can be measured with full spatial resolution and full time resolution.
