The omega, phi, kappa angles are defined as the angles used in order to rotate the (X,Y,Z) geodetic coordinate system and align it with the image coordinate system.
- Omega (ω) is the rotation around the Χ-axis.
- Phi (φ) is the rotation around the Y-axis.
- Kappa (κ) is the rotation around the Z-axis.
|Rotation around the X-axis (omega)||Rotation around the Y-axis (phi)||Rotation around the Z-axis (kappa)|
|Figure 1. Exterior orientation rotations/angles.|
The omega, phi, kappa are in degrees and can be positive or negative. This means, for example, that the value 350 degrees can be expressed also as -10 [0-(360-350)] degrees.
