| Abstract: | The reasons of an image distortion from infrared electroviewer are analyzed and a calibration model is set up for the nonlinear distortion. The model can be used in any imaging system which has a nonlinear radial distortion. The experimental result of calibrating the image distortion for the IR electroviewer is shown in this paper, the maximum position error is less than 1 pixel. The model can be expanded and grafted. |
