飞机订票系统设计： 要求： 假定民航机场共有n个航班，每个航班有一航班号、确定的航线（起始站、终点站）、 确定的飞行时间（星期几）和一定的成员订额。试设计一飞机订票系统，使之能提供下列服务： 1、航班信息录入功能(航班信息用文件保存) 2、航班信息浏览功能 3、查询航线：（至少一种查询方式） 1按航班号查询 2按起点站查询 3按终点站查询 4按飞行时间查询-Aircraft booking system design: requirements: the assumption that there are n Civil Airport flights, each flight has a flight number to determine the route (the starting station, terminal), to determine the flight time (several weeks) and a member of a certain set amount. Test design one aircraft booking system so that it can provide the following services: 1, flight information entry function (flight information using file) 2, 3 flight information browsing, query routes: (at least one query mode) one by flight number Query 2 Query 3 points according to the starting point for inquiries by the terminal 4 in accordance with time-of-flight inquiry

车牌定位－－－VC++源代码程序 1.24位真彩色->256色灰度图。 2.预处理:中值滤波。 3.二值化:用一个初始阈值T对图像A进行二值化得到二值化图像B。 初始阈值T的确定方法是:选择阈值T=Gmax-(Gmax-Gmin)/3,Gmax和Gmin分别是最高、最低灰度值。 该阈值对不同牌照有一定的适应性,能够保证背景基本被置为0,以突出牌照区域。 4.削弱背景干扰。对图像B做简单的相邻像素灰度值相减,得到新的图像G,即Gi,j=|Pi,j-Pi,j-1|i=0,1,…,439 j=0,1,…,639Gi,0=Pi,0,左边缘直接赋值,不会影响整体效果。 5.用自定义模板进行中值滤波 区域灰度基本被赋值为0。考虑到文字是由许多短竖线组成,而背景噪声有一大部分是孤立噪声,用模板(1,1,1,1,1)T对G进行中值滤波,能够得到除掉了大部分干扰的图像C。 6.牌照搜索:利用水平投影法检测车牌水平位置,利用垂直投影法检测车牌垂直位置。 7.区域裁剪,截取车牌图像。 -positioning plates-- VC source code procedures 1.24 true color-
