一种基于最小二乘法的摄像机非线性校正方法

摄像机线性化技术是机器视觉研究中的关键技术之一。本文针对高速彩色摄像机的非线性特性导致的图像畸变问题，分析其产生原因并给出了基于线性化校正的具体实现方法。在Visflal C＋＋6．0环境下实现了此算法，并应用异性纤维清除系统当中。试验结果表明，该方法能够提高系统性能并有效检测皮棉中的异性纤维。

The Linear Correcting Method About Non-linear Question of the Camera

The linear technology of the camera is the key technology in the research of machine vision, In this paper, to solve picture distortion problem, we analyze the non-linear characteristic of the colored camera of high speed, and provide the concrete implementation method based on that linear method of camera calibration. The algorithm have been realized under the environment of Visual C＋＋6.0 and applied to inspecting system for removal of the hetero fibers..The experiment result indicates that the method improves the system performance, and most of the hetero fibers can be detected.
