摘要
光条纹中心提取是线结构光三维视觉测量中的关键技术.把影响光条纹中心提取精度的主要因素归纳为工作环境、激光平面、被测物体和图像采集系统,并对其进行了对比分析.根据提取算法的理论基础、对图像信息的利用及计算思路特点的差异,将其分为几何中心方法和能量中心方法两大类.针对每类方法的计算思路、优缺点、改进方法、适用工况等在细分类方法中进行了对比分析和归纳总结.最后结合两大类方法的发展特点,提出了光条纹中心提取方法的进一步发展方向.
Extracting the center of a light stripe is one of the key techniques of the linear structured light for three-dimensional （3D） visual measurement .According to the influence of the accuracy in extracting the light stripe centers, the four key factors, which are the work environment , laser planes, measured ob-jects and image acquisition systems , are summed up and analyzed .On the basis of the differences be-tween the use of the image information and the characteristics of the calculated algorithms in the extraction methods, a new idea is proposed that they are classified into two different methods , which are the geomet-rical center method and the energy center method .Based on the differences between the two methods in algorithm thoughts, merits and demerits, ways of improvement, applicable conditions, they are subclassi-fied, compared, analyzed and summarized .At last, with the developing features of the two methods com-bined , it proposes the development trend of the light stripe extraction method .
