Paper Abstract

Focused on the problem of distortion correction for those images having simple contour, the synthetic method was described. In advance, without known camera parameters and any known world coordinates point in 3D space, the first order radial distortion coefficient can be estimated based on the fundamental property: a camera follows the pinhole model if and only if the projection of every line in space onto the camera is a line. Then the proposed distortion correction method, which characterized by its fast computing speed and good accuracy, maps not only pixel coordinates but also the grey values between the distortion image and non-distortion image. Several experiments and analysis were performed and presented on this paper. Finally, a comparative analysis about the accuracy and computational load with real data between this new method and the existed methods was put forward.
