Abstract

The measurement precision of camera inner orientation elements and distortion parameters directly affects the mapping accuracy. Especially for the mapping camera, the inner orientation elements and distortion parameters should be accurately measured and verified. There exists a lot of challenge in long focal length and large caliber camera aspects for the reasearch because the method solely relying on the size and precision of the test equipment is difficult to meet the testing requirements. With an eye to the trend of international development, we will explore a new calculation method of the inner orientation elements and distortion, which is proposed on the basis of the theory of the self-calibration for computing camera interior orientation elements and distortion. The initial value of the inner orientation element values are acquired by the solution of the different target images. Then,constructing reasonable distortion model to iterate the images, the high-precision inner orientation elements and calculation results can be achieved. This article is important to exploring the precision test approach of the inner orientation elements and distortion for the aerospace plane array camera.
