摘要
本文讨论了基于圆序列的具有径向畸变校正的整合图像问题 .由于相机旋转拍摄图片 ,可避免光源变化、遮挡和特征变化等出现在一般匹配中的问题 ,因此容易自动生成匹配点 .本文主要结果为 :(1)首次将径向畸变校对方法引入到图像整合问题 ;(2 )给出优化计算投影变换和径向畸变校正参数的目标函数并推导出目标函数线性化公式 ;(3)用非线性优化技术对投影变换和径向畸变校正参数同时迭代优化求解 .
The paper discusses the circle images-based image conformity with the lens-distortion correction.Due to finding matched points between images taken from the same point,it may avoid the problems of lighting changes and occlusion and aspect changes.It is easier than in the general point-matching problem.The paper has three main contributions:(1)At first we combine the radial distortion correction method with image conformity problem.(2)The paper presents the optimal objection function of projective transformation and lens-distortion parameters and derives the linear formulate of the optimal objection function.(3)The projective transformation and lens-distortion parameters are computed simultaneously with the nonlinear optimal method.
