摘要
扫描变形在图形处理与目标识别中有非常不利的影响,如何确定扫描变形和减少扫描变形的影响并没有一般的方法,该文通过对比几何定位符的位置关系来确定扫描变形,并通过图形膨胀来消除扫描变形的影响。实验证明这种方法可以有效地除去图形处理中扫描变形引起的误差。
The scanning distortion of image processing and pattern recognition is very troublesome.The general method of checking up the scanning distortion and eliminating isn't good.We develop one method to check up the scanning distortion through the position relation of geometry anchor point and to eliminate the scanning distortion through the image dilation.Experimental results show that the proposed method can effectively eliminate the image distortion.
