摘要
基于多项式校正方法,建立了针对图像坐标的公式模型,利用MATLAB中的曲面拟合工具(Surface Fitting Tool)得到了多项式参数,实现了对紫外探测器成像畸变的校正。本文介绍了楔条形阳极紫外探测器的畸变产生原因以及多项式校正的原理,设计了一个应用于Lab VIEW的dll模块,通过小孔掩模板实验求得多项式并应用于分辨率板的成像,实现了对分辨率板成像的畸变校正。
In order to correct ultraviolet detector＇s distortion, the formula model of polynomial correction method is established. And the parameters of polynomial are computed through using the Surface Fitting Tool of MATLAB. The causes of distortion of the wedge-strip anode are analyzed and the principle of polynomial correction method is introduced.A dll for LabVIEW is designed which can correct distortion. The experiments show that the method can correct distortion effectively.
