摘要
本文针对数字近景工业摄影测量系统的单相机模式下测量笔参数标定问题,提出一种"替代法"进行测量笔标定实验,并对标定方法的精度、可行性分别进行"外附和精度"和"单点重复性"验证。实验结果表明,该方法标定精度能够达到0.1mm,标定后的测量笔文件在系统中具有良好的实际使用效果,满足工业生产对精密工业测量的要求。
In order to solve the problem of measuring pen parameter calibration in single camera mode of digital closerange industrial photogrammetry system,a"substitution method"is proposed to carry out the calibration experiment of measuring pen,and the accuracy and feasibility of the calibration method are verified by"attachment and accuracy"and"single point repeatability",respectively.The experimental results show that the calibration accuracy of this method can reach0.1 mm,and the calibrated pen file has a good practical application effect in the system,which meets the requirements of industrial production for precision industrial measurement.
