摘要
鉴于现有的精度分析方法多为针对相机参数对精度影响的定性分析而缺少针对特定系统的量化分析模型,建立了双目测量系统数学模型,推导出相机参数、摆放角度、摆放基线、加工装调精度与系统精度之间的解析关系。利用该解析关系可以根据系统的精度要求,确定相机的参数、光学系统的安装精度、加工精度等参数,从而实现了可量化的系统设计,同时给出了完整的示例计算。
The current precision analysis methods are mainly focusing on the qualitative analysis of the effects of the camera parameters on the precision instead of the quantitative analysis of the specif-ic system. In this paper, a model for the binocular vision measurement system was established and analytical relationship among the camera parameters, the fix angle, the base line, the machining precision and the system precision was derived. O n this basis, the camera parameters, the installa-tion precision and the machining precision of the optical system could be determined according to the precision requirements of the system. Thus the quantifiable system design could be realized and a complete calculation example was given.
