摘要
回归反射球基准尺广泛应用于数字近景摄影测量系统的标定。提出了一种回归反射球基准尺校准方法,建立了由三路激光干涉仪、高分辨率双远心成像瞄准模块、高精度直线气浮运动机构等组成的测量系统。对名义值为500mm、1000mm、1500mm、2000mm的4种规格回归反射球基准尺进行了长度测量实验,结果表明该方法可以满足回归反射球基准尺的校准要求。
A calibration method of the retro⁃reflective ball scale⁃bar is proposed.The calibration instrument is composed by three⁃channel laser ranging device,high resolution bi⁃telecentric optical aiming module and air floating translation stage.Four fix⁃length retro⁃reflective ball scale⁃bars,which the nominal values are 500mm,1000mm,1500mm and 2000mm,are measured by the calibration device.The result shows that the retro⁃reflective ball scale⁃bar can be calibrated precisely by the the method proposed in this paper.
