牌照字符分割
License plate character segmentation
完成牌照区域的定位后，再将牌照区域分割成单个字符，然后进行识别。字符分割一般采用垂直投影法。由于字符在垂直方向上的投影必然在字符间或字符内的间隙处取得局部最小值的附近，并且这个位置应满足牌照的字符书写格式、字符、流水槽钢模具 不锈钢铸件 扭王字块模具 井盖钢模具 标志桩模具 调匝式消弧线圈 风冷控制柜 烤漆龙骨尺寸限制和一些其他条件。利用垂直投影法对复杂环境下的汽车图像中的字符分割有较好的效果。
After the location of license plate area is completed, the license plate area is divided into single characters, and then recognition is carried out. Character segmentation generally uses vertical projection method. Because the projection of characters in the vertical direction must obtain the local minimum value near the gap between characters or within characters, and this position should meet the character writing format, character, size limit and some other conditions of license plate. The method of vertical projection has a good effect on character segmentation of automobile image in complex environment.
