Ongoing project: Automatic star and planet detection + labelling

[danteffm]

Hi everybody,

I'm in the process of developing a script which is able to identify and lable the 50 brightest stars and planets automatically from my allsky camera.
Step 1 is a manual calibration by picking 4-6 stars on one of my allsky pictures using a python script
Step 2 is using equisolid projection based on the values calculated from the manual calibration
Step 3 is the labeling process - at the moment, I'm able to generate this result...
My plan is to do this automatically - upload a picture, script detects date and time by the filename and starts the processing. A bit like astrometry but for indi-allsky ;-)

That is very cool! I have considered adding a feature like this to indi-allsky, but nothing beyond just considering the idea.

I had played around with slicing/segment the image and using local astrometry.net to platesolve. Sliced/segment the image so astrometry.net is able to handle the fisheye projection better, and the coordinates more match each image segment.

equisolid projection based on calibration is a neat idea.

New results! The detection now is working in 3 steps:

1. Equisolid projection and labelling + json
2. Peak identification and correction of circles + json
3. Processing ofd final result with image + json

Next step: Build a backend based on html/javascript stuff and have an frontend available via apache...

That's the Debug view of the refinement-script - it uses the results of the first overlay, checks for white peaks and plots the distance between the first overlay and the peaks. Tbh: The first overlay is really, really good imho.

Very very cool project. Do you envision doing this for every frame or select frames, or intervals? I think for every frame would be problematic for the timelapse, but one, or few at intervals, could be very interesting for the timelapse to highlight sources for the traces, while still having specific single images that show their position at specific times...

Phew... you’re putting wild ideas in my head. I already have a script for batch processing which is running quite well. With the results it should be possible to generate a timelapse with labels. Even with traces... woah... 💯 nice idea!
