摘要:
高铁白车身的腻子打磨质量对高铁列车运行时的风阻性能有较大影响,该打磨质量主要通过测量其表面平整度来评判,当前使用较多的是人工检测方式,存在质量不高、效率较低的缺点;因而具备高效率、高精度等优势的基于双目光的测量方法在对大尺寸工件测量手段上逐渐受到重视。文章介绍了对高铁白车身展开三维测量时使用双目结构光的测量方式,并基于多频外差展开算法进行相位展开;提出通过建立“极线斜率—相位”查找容器来进行快速匹配;最后进行了高铁白车身测量实验,验证了双目结构光测量方法的精度和速度。
Abstract:
Putty sanding quality of high-speed train body-in-white has a great influence on wind resistance of train. Sanding quality is mainly judged by the measurement of surface smoothness. Currently, manual detection method is widely used, which has the disadvantages of low quality and low efficiency. Binocular-based measurement method, which has the advantages of high efficiency and high-precision, has gradually been paid more attention to the measurement of large-sized workpieces. It proposed a binocular-based measurement method for high-speed train body-in-white, expanded phases based on the multi-frequency heterodyne expansion algorithm and established a "polar slope-phase" search container for fast matching. Finally, a high-speed white-body measurement experiment was carried out to verify the binocular structured light precision and speed performance of this method.
