Abstract

The paper gives a scheme of the algorithm and the architecture of the information processing system of IR beacon image in the APT system. The CMOS image sensor gets the IR beacon's image in the optical antenna. The FPGA implements the IR image preprocessing and the DSP offers the possibilities of processing large high-resolution images. The wavelet transform is used in the image preprocessing, which can decompose the image in multi-scale to select the different frequency components. The IR beacon's position is detected based on gravity center, and the precision servo system finishes the tracking of the IR beacons. Thus the system can implement the acquisition, pointing, tracking and establish the FSO communication link in real time.
