| 摘 要： | 提出了一种基于分形盒维数与投影法的汽车牌照定位的方法，通过计算分形盒维数搜索到包含车牌的矩形区域，然后对此区域二值化，最后使用投影法精确得到其中车牌的边界坐标，从而将车牌完全从背景中分割出来．仿真实验取得了满意的结果，表明了此方法是可行的、有效的。

| Abstract: | A method of automobile license plate based on fractal box dimension and projection is presented. We search the rectangle area by calculating fractal box dimension, and then binarize the area, the precise edge coordinate of automobile license plate location is confirmed by using projection method, thereby we segment the plate entirely from background. The experiment obtains a satisfied effect, so the proposed method is feasible and effective. |
