Moreover , aiming at the location of inclined license plate , we have proposed the algorithm based on gray changing characteristic and orientation field . in this section , we discussed in detail the application of mathematical morphology operator in rough locating objective region and introduced the theory and realization method of orientation field . then we used it to detect inclined angel of objective region , finally we can precisely locate and emendate the inclined license plate based on detection result , and so we provided the favorable foundation for segmenting character 此外针对倾斜车牌区域的定位分割问题，提出了基于灰度变化特性和方向场计算的定位算法，其中详细讨论了数学形态学算子在目标区域粗定位中的应用，重点介绍了方向场计算理论和实现方法，并将其应用于目标区域倾斜角度的检测，根据检测得到的结果进行了倾斜车牌区域的准确定位和校正，为后续的字符分割打下良好的基础。

This dissertation is dedicated to the algorithm research of image registration applied to navigation . information such as attitude angle of aircraft is used to emendate the large - geometry - distorted image , so the research of this dissertation is based on the hypothesis that images used have small geometry distortion 针对图像匹配在导航中的应用，提出了对于存在大的几何失真的图像利用飞行器本身信息进行几何校正的方法，所以本文算法的研究都是基于小的几何失真这一假设的。
