摘要
光切法是近十多年发展起来的一种三维曲面非接触测量方法。轮廓提取是光切法的关键。论文论述了轮廓提取的概念,给出了轮廓线提取前的预处理,提出了一种从理论上达到无限薄光平面的轮廓提取方法,并对此作了推导。
The Light-sectioning Method for the3-D curve as one of the non-touching measuring is developed more than decade.The key of the Light-sectioning Method is the outline extraction.In this paper,the conception of outline ex-traction is described,and the precondition of the outline extraction is given.Then,a kind of method for the outline ex-traction of a plane light ,which is indefinite thin theoretically,is presented,and the kind of method is derived.
