摘 要: | 提出一种基于特征面片的复杂型面轮廓三维视觉测量方法.该方法包括多模式局部特征检测与匹配、特征面片集初始化、膨胀、滤波等重构过程,其输入是已标定的立体图像,输出是覆盖表面的可视稠密面片集.该方法不需要目标和场景的任何初始边界信息,能够自动检测和抛弃外部点和缺失部分;不需要对邻域特征进行任何平滑处理,仅需通过局部单演特征一...

Feature Patch-Based Vision Measuring Technique for Complex Surface and Silhouette |
| |
Abstract: | A feature patch-based three-dimensional vision measuring technique for complex surface and silhouette is proposed.There are several procedures for the proposed method including detecting and matching multi-modal local features,initializing,expanding and filtering patch sets.The algorithm outputs a dense set of rectangular patches covering the surfaces visible in the input calibrated images.The first step of the proposed algorithm is implemented as a matching,expanding,and filtering procedure.It starts from ... |
