What coordinates of ground control points are needed for photogrammetry?

Surface control points are used to obtain the mapping.

Using photogrammetry indoors, with the help of a few ground control points, the ground coordinates of control points needed for surveying and mapping are obtained.

The coordinate systems commonly used in photogrammetry include image plane rectangular coordinate system, image space rectangular coordinate system, image space auxiliary coordinate system, ground photogrammetry coordinate system and ground photogrammetry coordinate system.
