Missing build_lost_in_space_catalogue interface #8

Open janeabad opened 4 months ago

janeabad commented 4 months ago

The is no method available to build the lost-in-space catalog from the stars catalog.

When the user attempts to resolve the stars on an image without a priori data, it raises the following error: ValueError: The lost in space catalogue has not been loaded. Cannot solve lost in space problem.See build_lost_in_space_catalogue interface for details.

I couldn't find any script or method to build the lost-in-space catalog.

Hi @janeabad

Sorry, the LIS was a work in progress that wasn't functional, so that's why the build_lost_in_space_catalogue tool is not included. I've still not had time to work on the LIS solver so its unlikely to be chanced anytime soon, and I'll likely remove reference to it in an upcoming release. If you do need a LIS solver, I've had success with using astrometry.net to get an initial solution and then using GIANT to refine the solution/do camera calibration. There's also a sister project from NASA https://github.com/nasa/COTS-Star-Tracker which I believe has a LIS solver.

Hi @aliounis ,

Thanks for your answer and no worries for the LIS. I have used astrometry.net in the past and I will use as you suggested.
