A size feature-oriented binocular vision re-measurement guiding method

By using a binocular vision-guided retesting method oriented towards dimensional features, a confidence evaluation mechanism is established for specific measurement features to identify and adjust the causes of low confidence, thus solving the problem of unstable dimensional measurement results in existing technologies and improving measurement accuracy and efficiency.

Abstract

本申请涉及双目视觉测量技术领域，公开了一种面向尺寸特征的双目视觉复测引导方法。该方法包括通过双目视觉系统采集被测物的左图像和右图像，并根据左图像和右图像通过双目视觉算法生成被测物的三维点云；确定至少一个待测尺寸及其对应的尺寸特征，尺寸特征为用于计算待测尺寸的几何特征；根据每个待测尺寸的尺寸特征区域内各点的可靠性，计算每个待测尺寸的尺寸置信度；尺寸特征区域为尺寸特征在左图像和右图像中对应的像素点的集合，以及在三维点云中对应的三维点的集合；在尺寸置信度不满足置信度要求的情况下执行复测，直至待测尺寸的尺寸置信度满足置信度，输出待测尺寸的测量结果。采用本方法能够提高双目视觉尺寸测量结果的可靠性。
