摘要
双目定位跟踪系统涉及到的关键技术有摄像机标定、立体匹配和三维重建等.在三维重建阶段,利用匹配的结果采用最小二乘法计算定位标靶上标记的三维坐标.实验结果表明,在现有条件下,双目定位跟踪系统的定位精度比较高,相对误差在1%以内;基于此定位跟踪系统,能够初步准确完成对经络的三维定位和实时显示,为临床诊断治疗和基础教学提供直观的分析依据.
The key technique of binocular stereo vision is composed of camera calibration,stereo matching and 3D coordinates computing.The 3D coordinates of tag on OPT are given by least square method through the results of stereo matching.The experiment has shown that the tracking system based on binocular stereo vision can position in a high precise level with small error under the current experiment condition.The relative error is less than 1%.Using this tracking system,the method presented in this paper can position and display human meridian in real-time at the primary level and provide more direct analysis foundation for clinical diagnosis treatment and basic education.
