Very good and illustrative explanation of DORI zones. I would mention that DORI comes from international standard IEC / EN 62676 part 4. There there is explanation of different operator tasks such as Detection, Observation, Recognition, Identification. I use free camera lens calculator from ipica to calculate DORI zones for different lens sizes and camera model. Their calc has a camera database with exact angles that is important for wide-angle cameras.
