广角摄像机标定及畸变图像修正方法研究

Study on Calibration of Wide-angle Camera and Distorted Image Correction

广角摄像机可获取大视角的景物视频信息,但是成像后图像畸变较大,为后期图像处理与分析带来困难。利用摄像机标定技术,通过求解广角摄像机内参数和畸变系数,对畸变图像进行了修正,消除图像几何畸变。文中的标定与修正方法具有通用性,适用于现有工程应用中各类摄像系统的光学畸变修正,有利于事后数据处理与分析工作。

Wide-angle camera can obtain the large angle view information,but the image distortion is larger after imaging,which makes it difficult for image processing and analysis later. The camera calibration technique is used to solve the distortion image by solving the parameters distortion coefficients of the wide-angle camera. This calibration and correction method is widely used,which is applicable to the optical distortion correction of various camera systems in engineering applications,and which is good for the post data processing and analysis.
