Correcting Distortion of Images from Non-Metric Camera

Abstract

Photogrammetric calibration methods for digital CCD cameras are usually capable of acquiring explicit distortion parameters. However, it would cause the correcting results to be less accurate due to irregular array with explicit image correction method. In order to produce images with less distortion, an implicit model was proposed in this paper. Moreover, the model was applied to correct images from a non-metric camera. The real tests with images indicate the improvement is more obvious in eliminating distortion on images.
