2.1.1.1 Rotation matrix for aerial photos

The x' axis lies approximately in the flight direction. In this case the matrix R is:

(2.1.1/4)

For photos in zenith direction either ϕ or ω may be set to 200 gon in equation (2.1.1/1).

The image vector in the aerial case is .

The original rotation angles ϕ ω κ can be recalculated from the elements of the rotation matrix here as follows:
