摘要:

为了提高相机标定结果的准确度,文中就相机内参和畸变参数的优化方法进行了研究。在建立准确的相机成像及标定模型基础上,根据模型参数估计的具体推导步骤,利用最大似然估计法对得到的参数进行结果优化,然后通过修改镜头畸变模型重新计算参数得到最终结果。实验证明,应用文中提出的流程求解相机内参和畸变参数,简单快速、准确度高且实用性强。

Abstract:

Study on the optimization method of camera internal and distortion parameters is conducted in order to improve the accuracy of the results for camera calibration. On the basis of camera imaging and calibration model, we optimize the parameters by the method of maximum likelihood following the specific steps, and get the final result by recalculating parameters through the lens distortion model. Experiment results show that application of the proposed process to solve the camera internal and distortion parameters, simple and fast, with high accuracy and strong practicability.

Key words: camera calibration, internal control, distortion parameters, optimization
