一种IGPS测量系统外参标定方法研究

Study on External Parameter Calibration Method for IGPS Measurement System

采用LM优化方法对IGPS测量系统的外参计算方法进行了详细的理论分析,建立IGPS测量系统统一坐标系和测量目标在指定参考坐标系下的位姿——三维位置坐标和转角进行精准计算,从而实现测量系统快速建场,完成对目标物测量等功能。

By using LM optimization method, the external parameter calculation method of IGPS measurement system is analyzed in detail, and the unified coordinate system of IGPS measurement system is established. Under the specified reference coordinates, the measuring target＇s position and posture—three-dimensional coordinates and rotation angle is precisely calculated, so as to realize the rapid construction of the measurement system and complete functions like measurement of the target object.
