摘　　要：由于光学镜头加工和装配误差的存在,数字相机拍摄图像常会出现非线性的几何畸变。针对这一常见问题,通过研究镜头畸变的数学模型和摄像机模型以及参数标定方法,在VC++环境下调用OpenCV库函数,实现了图像畸变校正。实验结果表明,该方法能够在保证无颜色失真的条件下获得理想的校正结果,并且实现简便、准确。Non-linear image distortion is an general problem in digital camera design because of the existence of processing and assembly error of optical lenses.In this paper,the non-linear digital image distortion rectification is implemented using the library function of OpenCV under the environment of VC＋＋ by analyzing the math model of the lens distortion,the camera model and the parameter calibration method.The experiment results indicate that this method is simple,efficient and accurate.
