Paper Abstract

Sun is used as light source for spectrum analysis of atmosphere material with light through atmosphere. The stronger sunlight enters the detector, the more accuracy can be achieved. However, due to the inhomogeneity of the atmosphere, the gray image of sun is not only irregular, even the interference of clouds will divide sun into different parts. A novel method for gray centroid of sunlight based on image recognition is presented. This method aiming at accurately obtaining the strongest sunlight through the atmosphere for detector uses the gray image of sun to calculate the actual gray centroid of sunlight.
