| 摘 要： | 文章通过对摄影测量学中基于空间前方交会的点投影系数法进行分析,建立了摄影测量的高程误差方程,重点分析了传输型测绘相机内方位元素误差对高程精度的影响。以1∶50 000比例尺地图产品为例,分析了某测绘相机的相机主距、主点位置、畸变等内方位元素对高程精度的影响程度,提出在测绘相机研制过程中在保证高程精度方面应注意的问题。

| Abstract: | This paper analyzed the point-projection-coefficient method which based on spatial forward intersection of photogrammetry and built the elevation error equation.The influence of real-time transmission mapping camera interior orientation on elevation precision was determined.Taking 1：50 000 scale mapping production as an example,calculated the interior orientation including focus,position of main point and distortion influence on elevation precision,and also proposed some issues which should be well considered during the developing process of the camera. |
