Abstract:

The determination of the center of mass of the light spot is a key step in the refraction based measurement of atmospheric temperature gradient. The algorithm for a light spot image’s center of mass calculation is introduced. The calculation is used in the refraction based atmospheric temperature gradient measurement. An adaptive auto thresholding method is used in the algorithm which can be adapted to various ambient environments. Experiment shows that the algorithm can be implemented easily and run in real-time; it is suitable to be used in the refraction based atmospheric temperature gradient measurement.

Key words: atmospheric temperature gradient, image processing, light spot center of mass calculation
