A distortion correction method of lateral multi-lens video logging image

According to the principle of the acquisition of lateral multi-lens video logging images, the distortion correction method based on camera calibration model is proposed. The proposed method is consisted of two steps. Firstly, space conversion. According to the image model, transform three-dimensional space coordinate into 2D image plane coordinate, establish corresponding relation of distortion image coordinate and image coordinate, find out the corresponding lens distortion parameters and the camera parameters, then work out correction coordinates through the distortion imaging formula based on the camera image model. Secondly, grey correction. On the basis of bilinear interpolation method, compute image pixel value, and achieve the effect of corrected image. The experimental results show that the use of the proposed method makes it possible to correct image distortion with high resolution realize image distortion correction quickly, and improve the image accuracy.
