摘要
论文介绍了在三维轮廓光切法中提取二维轮廓光带中心线的传统方法,针对传统方法依赖于对轮廓光带精确分割的问题,提出了一种直接使用DOG(DifferenceofGaussian)线条检测器提取轮廓光带中心线的新方法。实验结果表明该方法具有好的准确性及较强的抗噪声能力。
The traditional methods of extracting Lighting-Zone center axis in 3D profile measurement by Light-Sectioning method are introduced in this paper.A new method based on DOG（dlfference of Gaussian） line-detector for extracting Lighting-Zone center axis is proposed to avoid precise segmentation of Lighting-Zone such as that in the traditional methods.Experiment results show the good function of the new method in noise restraint and the precision of profile outline.
