摘要
对几种常用的阈值选取方法进行了理论分析与比较 ,并以基于面结构光投影法的三维物体形状检测技术研究为背景 ,从实验角度对类间方差法。
In this paper,a theoretic analysis and comparison is made for several thresholding methods in common use.And then,basing on the research of three dimensional object shape measurement, experimental results are shown to certificate performance of those methods.
