So, what about camera distortion? For communicating the information in an unambiguous manner in 2D printouts, there are a few better ways than the raw matrix.
The first best way is to display a deformed grid. This is readily intuitive and obvious to a person who has worked with cameras.
The second way is to display a normal map. This is readily obvious to someone who has worked with computer graphics extensively. Also, this data is easier to import into your software.
Okay, great! We have some good choices going on here for standards-oriented data design.
- Yes, no trickery here. Although mere angles can be indicated using only two angular integers, the industry standard is to use three-component rectangular vectors. So, stick with that.
