Sun position computation in a sample sky/cloud image

This repository is a minimalist working version of computing the position of sun in an image. This is inspired from the research performed in the following publications:

F. M. Savoy, S. Dev, Y. H. Lee, S. Winkler, Geo-referencing and stereo calibration of ground-based whole sky imagers using the sun trajectory, Proc. IEEE International Geoscience and Remote Sensing Symposium (IGARSS), July 2016.

summary

Usage

  • Please store the sample input image inside the image folder.
  • Run the script python2 find_sun.py. This computes the position of the sun in the image. Please note the definition of the reference axis in the image.
