双目PMP视觉测量中立体匹配方法的设计与实现
Design and Implementation of a Stereo Matching Method in Binocular PMP Vision Measurement
摘要
Abstract
In order to resolve the mismatching problems caused by the large change in the depth of the obj ects or the complex surface shape in the field of PMP visual measurement,this paper proposed a stereo matching method based on region segmentation and parallax correction.The basic principle of four-step phase shift method and the multi-frequency heterodyne were investigated,and stereo rec-tification method in OpenCV software package was used to rectify the raster image.The field of view of the cameras was analyzed according to the characteristics of the PMP vision measurement system. Using the characteristics of the phase information in the field of view and the parallax constraint,the principle and the method of region segmentation were proposed based on the mixed threshold.Fur-thermore,the valid parallax maps were obtained by parallax solving and parallax correction,and sev-eral test experiments were carried out to demonstrate the effectiveness of the proposed stereo matc-hing method in PMP visual measurement system.关键词
