摘　　要：摄像机标定是由二维图像获取三维空间信息过程中的重要步骤,是计算机视觉领域的研究热点。文中通过改进摄像机数学模型,提出一种快速精确的摄像机标定方法。该方法以平面标定法为基础,同时引入径向畸变和切向畸变以提高标定精度。在此基础上结合Open CV库,在Visual Studio 2015开发环境下实现了摄像机标定,并进行了实验验证,实验结果表明该方法具有较高的标定精度,计算速度快,过程稳定。Camera calibration is an important step in the process of acquiring three-dimensional spatial information from two-dimensional images. It is a hotspot in the field of computer vision. This paper proposes a fast and accurate camera calibration method by improving the camera mathematical model. The method is based on the plane calibration method, and the radial distortion and tangential distortion are introduced in order to improve the calibration accuracy. Based on OpenCV library, the camera calibration is realized in Visual Studio 2015 development environment, and the experimental results show that the method has high calibration accuracy, fast calculation speed and stable process.
