基于弧面映射的图像桶形几何失真的校正方法

An Adjustment Method of Image Barrel Geometry Distortion Based on Arc Surface Mapping

提出了一种新的三维映射几何建模方法,即通过弧面映射变换,先获取目标图与原图的像素一一映射关系,再采用四点线性插值方法,实现了对原图像的桶形几何失真校正。同时,对一幅实拍的家居图像进行了桶形几何校正实验,取得了比采用Photoshop软件处理更为理想的效果。

This paper puts forward a kind of new 3-dimension mapping geometry modeling method:first we obtain the one by one mapping relations between the object picture and its original one,and then use the 4-point linear interpolation method so that we realize the barrel geometry distortion adjustment of the original picture.We implement the barrel geometry distortion adjustment of an actual furniture picture,and the results show that our method has a much more ideal effect than that of using the Photoshop software.
