短焦距图像非线性变换研究与实现

Short focal length image nonlinear transformation Research and Implementation

随着科技发展,视频图像技术已经融入现代生活。通常,在相机拍摄过程中图像会发生形变,影响输出结果,不能达到图像质量要求。本文是针对短焦距摄像机镜头的畸变进行数字校正,通过建立镜头畸变模型,找出径向畸变算法,并利用光学成像的基本规律计算关键点值,从而对原始图像进行校正。最后利用MATLAB对研究内容进行验证。验证结果表明,该方法具有简单、实用的特点。

With the development of science and technology,the video and image technology has been integrated into modern life.Typically there will be deformed during shooting,it will affect the output results and the quality of the image requirements can not be reached.In this context,the short focal length of camera lens distortion will be corrected.Radial distortion algorithm can be found through establish the model of lens distortion,and calculate the key point value by the basic law of the optical imaging.Finally,using MATLAB to verify the research content,and the results show that the method is simple and practical.
