Abstract
In case of short range photogrammetry, the uneliminated vertical parallax often exists in order about a few ten microns and also no good precision results can be obtained. One of the most occurable cause is unsuitable interior orientation elements of the used camera. In photogrammetry, I hope the camera to be used in its best condition. In this paper I show the method for measuring the interior orientation elements analitically. It is based on the central projective relationship between the XYZ coodinate value in object space and the corresponding xy coordinate value in its image space.
And also this method is confirmed by using the simulation model mathematically.
