摘要

为了准确标定超广角红外相机, 从超广角红外相机的泰勒多项式标定模型出发, 提出了一种基于主动红外辐射标定板的标定方法。该标定板克服了以往超广角相机标定板制作困难的问题, 可用于标定超广角红外相机。实验结果显示, 角点平均重投影误差(MRE)和角点重投影方均根(RMS)分别为0.30和0.34像素。

Abstract

In order to accurately calibrate the ultra-wide angle infrared camera, a calibration method based on the active infrared radiation calibration checkerboard is proposed based on the Taylor polynomial calibration model of the ultra-wide angle infrared camera. The calibration checkerboard overcomes the difficulty of making a ultra-wide angle camera calibration checkerboard and can be used to calibrate ultra-wide angle infrared camera. The experimental results show that average reprojection error (MRE) and reprojection root mean square (RMS) of the corners are 0.30 and 0.34pixels, respectively.
