A python package for the evaluation of the cloud coverage in all sky camera images. The images are searched for stars as bright blobs and compared to a star catalog. Matching positions between detected stars in the image and catalog stars suggest a starry night sky, while catalog stars without matches in the image implay an overcast sky.
The package can be downloaded and installed with following commands:
$ git clone git@github.com:tudo-astroparticlephysics/all_sky_cloud_detection.git
$ cd all_sky_cloud_detection/
$ pip install .
Currently, cameras.py provides information of all sky cameras located on La Palma and at the South Pole.
Code for the analysis of test images can be found here.
