Camera Calibration Method Based on Laser Ranging

To the limitations of the existing camera calibration methods, a new camera calibration method Based on laser ranging was presented. This method is to calculate the three dimensional coordinates of target point by use of the distance measured by laser ranging sensor, and extract laser spot from the acquired image with the spot of target point, and then calculate the sub-pixel coordinates of laser spot center, at last calculate the interior and exterior parameters of the camera through the projective transformation, thereby realize the camera calibration. The experimental results show that after the camera is calibrated by the method presented by this paper, the various distortions are overcome, and the acquired images are basically no deformation (warp), and the visual effect is better.
