轨道车辆内饰尺寸公差的快速测量方法及应用

摘要

随着轨道交通行业的快速发展，各界对轨道车辆的制造要求也越来越高。轨道车辆内饰件装配是轨道车辆生产的重要质量控制点。内饰件装配的控制综合反映了轨道车辆产品开发和质量控制水平。利用基于结构光的视觉测量方法，实现了车辆内饰公差的快速测量，并能够实时显示被测物体的空间几何尺寸(角度、圆度和平面度等物理量)，对于车体内饰的装配误差检测有着重要的意义。实时显示能够直观地显示配件或车体的误差，从而可以提高车辆的装配效率。%With the booming development of rail transit industry,there is more of a requirement to the manufacturing of railway vehicles.The assembly of interiors plays an important role of deciding the quality of railway vehicles production. Assembly control of interiors also reflects the level of product development and quality control.Rapid measurement of rail-way vehicles’interiors dimensional tolerances has been realized by a kind of visual measurement methods based on structured light.It also can display the objects’size,angle,roundness,flatness and other physical quantities in real time,which is of great significance to the vehicles’assembly error detection.The display in real time gives a chance to observe the error of re-placement or vehicles body directly and the assembly efficiency will be improved.
