Convert pinhole model to optical bar #233

Closed oleg-alexandrov closed 1 year ago

oleg-alexandrov commented 5 years ago

Historical images from declassified KH spy satellites are modeled in ASP using the optical bar model. This model has some parameters (e.g, tilt, scan speed, etc), that are not documented and can vary a lot. If the wrong numbers are used, or numbers copied from a different mission, the DEMs can show up very wrong.

It is very easy to model things with the pinhole model though. All that is needed is the focal length, and the optical center can be assumed at image center if nothing is known. It would be nice if the best fit optical bar model can be generated from an initial pinhole model once that one is validated. Our tool convert_pinhole_model could be expanded to do that.

No funding for optical bar work for the foreseeable future.
