摘要:

介绍了双目立体视觉原理,并利用该技术解决了电动汽车自动换电过程中对电池表面三维信息的定位要求。采用张正友标定法完成相机标定,利用区域匹配原则进行特征点匹配,完成电池的三维重建。实验结果表明,双目视觉的定位精度满足换电要求。

关键词: 双目立体视觉, 相机标定, 特征匹配, 换电

Abstract:

The principles of binocular stereo vision are introduced in this paper,and then binocular stereo vision technology is used to meet the localization requirements of the cell surface during the fully automatic changing cell for electric vehicle.Zhang Zhengyou calibration method is used to complete camera calibration and the regional matching principle to match feature points for the three-dimensional reconstruction of the cell.Experimental results show that the accuracy of binocular vision location meets the requirements for the changing cell.

Key words: binocular stereo vision;camera calibration;feature matching;changing cell
