摘要	Camera with wide angle can enlarge the field of view, but it can also introduce serious lens distortion at the same time. It is necessary to correct the distorted image obtained from the wide-angle camera. First, we extract the distorted lines from the image, and then we use the method based on the property that a straight line can be imaged into a circle, with the single parameter division model. In the process of distorted lines fitting to arcs, the method is used to calibrate the initial approximation of the distortion parameter and distortion center. And we propose an entropy function in the Hough space to measure the straightness of the undistorted curves. This entropy function is used to optimize the initial approximation, and then to calculate the accurate final distortion parameters and distortion center. Based on the engineering example, we respectively use the arc fitting method and the presented method to correct the target distorted image. The simulated and the experimental results show that the proposed method in this paper can use a single image to obtain high accuracy distortion calibration coefficient. At the same time, this method has high stability. 2015, Board of Optronics Lasers. All right reserved.
