| 摘 要： | 本文介绍了一种被称作有限元法的补偿系统误差方法,即将每张象片的象主点坐标和象点的“焦距”作为待定的补偿参数参予全区整体平差。实例计算表明,方法不但可行。而且有效地提高了加密精度,特别是高程精度。

| Abstract: | This paper is devoted to introduce a new approach of the compensation of systematic essors named the Finite Element Approach, in which the photogrammefric coordinates of the principal point of each photograph and the focal length at the each point of the photograph are treated as unknown parameters into block adjustment. The results of the practical tests show that the approach by proposed is correct and feasible, and also show that the adjustment precision has raised considerably. |
