针对堆叠零件识别定位耗时长与精度低等问题,设计了一种高效的识别定位方法.在识别方面,提出了一种分类器融合方法.通过使用此方法训练出一个权重可动态调整的分类器模型,成功实现了对堆叠零件的分类识别.在定位方面,采用改进随机Hough变换的方法提取目标边缘.利用堆叠零件的边缘几何特征,重建出堆叠零件的空间姿态信息.最后,对单个特征分类器和组合特征分类器进行了分类识别实验和模型评估.实验结果表明,特征融合后的分类器展现出更高的识别精度和更稳定的准确率波动,表明其具有更好的分类鲁棒性.
Research on Recognition and Location of Stacked Parts Based on Binocular Vision
An efficient identification and positioning method was designed to address the issues of long time and low accuracy in identifying and positioning stacked parts.In terms of recognition,a classifier fu-sion method was proposed.In terms of recognition,a classifier fusion method was proposed.By using this method to train a classifier model with dynamically adjustable weights,the classification and recognition of stacked parts has been successfully achieved.In terms of localization,an improved random Hough transform method is used to extract target edges.Utilize the edge geometric features of stacked parts to reconstruct the spatial pose information of stacked parts.Finally,classification recognition experiments and model evalua-tion were conducted on individual feature classifiers and combined feature classifiers.The experimental re-sults show that the classifier after feature fusion exhibits higher recognition accuracy and more stable accu-racy fluctuations,indicating better classification robustness.
