一种考虑畸变的摄像机线性标定简化方法

A simplified linear camera calibration approach in view of distortion

根据视觉机器人系统结构特殊的特点,作了大量的简化,采用线性标定方法。但考虑到摄像机的视场仍然比较大,提出了基于拟合平面的线性畸变纠正方法,将畸变的图像坐标纠正到理想图像坐标,而后根据摄像机线性标定模型,计算出世界坐标,完成标定工作。实验结果表明,该方法简单、快捷,且精度也能达到较高的水准。

According to the special structure of our robot vision system, the linear calibration is employed with put forward. a lot of simplifications. But in view of camera distortion, a new linear rectification approach is Consequently the linear camera model can be used to realize calibration. The experimental validation shows the convenience and considerable precision of this approach .
