| 摘 要： | 在线结构光视觉测量系统中,光条中心的提取精度直接影响到整个系统的测量结果.由于光条宽度不同、光照不均匀及待测物体表面性质的差异,使得精确地提取光条中心存在一定难度.根据线结构光的特点提出了2种提取算法,分别为二值形态学细化算法和高斯分布的曲线拟合算法.实验结果表明,2种算法在测量中均具有可行性,且后者提取精度较高,更适合于光条中心线提取.

| Abstract: | In the vision measurement system of line-structed light,the extracting precision of light stripes center affects the precision of measurement system directly.It is quite difficult to extract light stripes center precisely because of different light-stripes widths,uneven illumination and differences in the nature of the objects surface.According to the characteristics of line-structured light,two extracting algorithms of light stripes center were proposed including two-value morphological thinning algorithm ... |
