Abstract
A beacon image tracking algorithm during daytime is proposed. The camera view field noise reflected by sunlight and detector noise in the spatial and frequency domains are analyzed. Two frequency domain filters are used to detect candidate regions. The results show that the algorithm has high precision, high speed, and high reliability, and can be applied to the daytime satellite-to-ground beacon tracking.
