航摄机检定主点坐标的使用问题

The Application of the Coordinate of Principal Point of Camera

在航测内业生产过程中存在一个困扰多年的航摄机主点偏移问题 ,即是否使用航摄机检定主点坐标以及该如何使用检定的坐标。本文通过论述两种航摄机检定主点坐标 (PPA和PPS)的含义及区别 ,并在广泛调研的基础之上 。

There is a problem about the offset of principal point of camera in photogrammetric measurements. The operators always do not know if they should input the value of the principal point or not and how to input it. The paper introduces the meaning and difference of two kind of coordinate of principal point of camera(PPA & PPS).
