摘要
桶形失真直接影响了对图像的分析理解,为了得到比较完好的图像,对拍摄到的图像进行几何校正是十分必要的。本文通过对图像中各象素作变换,采用多项式地址修正法实现了对图像桶形几何失真的校正,并对实拍的围棋棋盘图像进行了桶形几何校正实验,取得了比较理想的结果。
Barrel distortion affects image analysis and comprehension directly. In order to get a high quality picture, it is necessary for us to do some geometric correction on shot images. Through transforming pixels in the image,this paper adopts L muhinomial address correction to realize barrel distortion correction of images. An experiment of barrel distortion correction on real go board image is presented which has achieved a comparatively better effect.
