Design and control of optical steady image system of aerial camera

Abstract

Abstract In order to solve the problem of aerial photography imaging blur, an aerial camera optical image stabilization system is designed. Based on the principle of optical image stabilization, a forward image stabilization system of aerial camera was designed by analyzing the imaging blur of aerial camera. The equivalent resolution of the system is 500-1000 l p/mm, and the corresponding pixel size is 1-2 μm. Aiming at the optical image stabilization system to establish its PID and corresponding adaptive PID control model, establish its closed-loop system transfer function, and use MATLAB to simulate and analyze the control system. The results show that the whole image stabilization system becomes stable after 0.01s and can achieve the goal of image stabilization. It solves the problem of forward image motion of aerial camera, and greatly improves the imaging effect of aerial camera when it works.
