摘要

提出了目前采用的脱靶量修正模型的适用条件，采用坐标变换推导经纬仪脱靶量修正公式，获得与球面三角学相一致的推导结果，并在此基础上推导出成像系统无照准轴平行约束条件的通用脱靶量合成公式。采用光学系统的物方焦点作为摄像机系统的投影中心，推导出投影中心与经纬仪回转中心不重合条件下摄像机投影中心在测量坐标系中的坐标值。经测量设备的实际验证，该修正方法突破了现有修正模型的局限性，适用于多传感器经纬仪成像系统

Abstract

The existing tracking error correction formula is derived from coordinate transformation compared with spherical trigonometry

which suitable conditions are proposed. A new tracking error correction model is deduced without its optical axis paralleling the collimating axis

and the coordinates of camera projection center in measuring coordinate system are calculated without regard to coincidence between the optical center and the theodolite rotation center. The approach breaks through the limitation of existing model

and which is suitable for multi-sensor imaging system theodolite
