Analysis of atmospheric pressure and temperature changes on the image quality of aerial camera

This paper starts from the study of the aerial camera´s work environment, analyzes the temperature and atmosphere pressure changes on aerial camera´s imaging quality of influence. Point out that when the altitude of the camera changes, atmospheric pressure and temperature of constant change, so the camera´s optical focal surface position changes, thus affecting the image quality of the camera, causing changes in the camera´s focal surface optical, and affecting the camera´s image quality. Summarize the rules that the temperature and pressure influence the image quality of the camera in aerial environment. Analyze the various environmental conditions on the impact of camera´s image quality. For different types of camera, put forward the corresponding convergence compensation method, and provides a reference value to the development of the aerial camera.
