According to the noise of the background light detected by the image sensor, the eigenvalue of the light background is defined, which is used to describe the effect of the optical background noise of the satellite link on the aiming, capturing and tracking of the satellite optical communication. The effect of optical signal identification and capture is analyzed under the optical background noise of the terrestrial link. At the same time, a path optimization algorithm of the captured optical spot is proposed. According to this algorithm, the characteristics of the optical background noise in the terrestrial laser link can be obtained Law, and expounds the rapid recognition method of optical signal in the case of optical background noise. The simulation results show that this algorithm can quickly recognize and capture optical signals under light background noise, meet the requirements of real-time image processing and enhance the anti-interference ability of image processing systems. Therefore, The reference meaning.
