| 英文摘要: |
| The projection method, that is a method of 3D surface profile detection based on the combination of linear structured light scanning measurement and stereoscopic vision measurement, can detect the surface profile of optical component online quickly and accurately. In this paper,an image processing algorithm is presented including pre-processing, area-based stereo matching, curve fitting and surface characterization testing, to recover the surface profile model of optical component. The results of the experiments show that this method can reconstruct the three-dimensional exterior characteristics of the optical component truly and accurately. Therefore, the research is feasible and has research value. |
