一种新型检校场下的POS系统视准轴误差检校研究

Research on the Boresight Calibration of Integrated DGPS/IMU System in the New Calibration Field

机载POS航空摄影测量系统在数字城市建设、地面导航等方面得到广泛的应用,为满足测图精度要求,作业前对该系统的视准轴误差进行检校是十分必要的。传统的检校方法具有场地维护不便、检校过程繁琐、后期数据处理任务重的缺陷,基于此,本文提出一种新型检校方法,经实验验证,该检校方法精度高,操作简便,能够满足测图规范的要求,具备一定的应用价值。

DGPS/IMU photogrammetry system has been widely used in digital city construction, ground navigation. It is necessary to do boresight calibration for meeting the requirement of the mapping accuracy. The traditional calibration method has some bad aspects of inconvenience to maintain the site, calibration process cumbersome, data processing defects of heavy task. This paper raises a new calibration method , this method has the characteristic of high accuracy, simple operation, it can satisfy the mapping requirements and has the certain application value.
