基于特征匹配的螺柱视觉识别方法研究

摘要

Recognizing and localizing a stud is the core part of the automatic stud sorting system .A visual recognition method of stud based on feature matching was proposed .The recognition and location process was divided into two stages :training stage and recognition stage .In the training stage ,a database of features of the stud samples was established .In the recognition stage ,the type and pose information of the stud were detected ,and it would be used to sort out the stud .Experimental results show that the method is able to recognize and localize the studs that are in arbitrary poses .%提出了一种基于特征匹配的螺柱视觉识别方法。该方法将螺柱识别与定位过程分为两步：训练和识别。在训练阶段，完成螺柱样本特征库的建立；在识别阶段，检测待识别图像中螺柱的类型和位姿数据，为分拣提供准确的螺柱类别及抓取位置信息。实验结果表明，该方法能够对视场范围内任意摆放螺柱实现准确识别与定位。
