In the test course of static transfer function of TDI CCD camera  because of the influence that gets environmental and artificial etc. factor  the value of static transfer function measured at any time is between unceasing fluctuation  so  make accuracy reduce. To solve this problem  a kind of accurate measurement technique of static transfer function is put forward. First  before carrying out the measure of static quiet of transfer function  the best test point of transfer function of the TDI CCD camera must be determined  it is parallel to guarantee the rectangle target surface of parallel optical pipe and camera focal plane maintenance parallel  and again guarantee target strip in rectangle target and TDI CCD in camera focal plane maintenance vertical. TDI CCD catches rectangle target image  per 1000 lines of target mark image as a measures sample of static transfer function  exclude because of atmosphere tremble twisted  vague rectangle target mark image  retain 500 distinct and steady target mark image as measure sample set. Then  calculate the static transfer function of each measure sample respectively  take the average of all static quiet transfer function in measure sample set as the static transfer function of camera. Finally  the measure of the static transfer function for TDI CCD camera makes error analysis. Experimental results indicate that the value of the static transfer function of TDI CCD camera measured with this kind of method is 0.2923  with before measurement technique comparison  the value of static transfer function has raised 0.02  makes the accuracy of the measure of static transfer function have gotten raising.  
Analysis of atmospheric pressure and temperature changes on the image quality of aerial camera (EI CONFERENCE) 会议论文  OAI收割

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. 2011 IEEE.
