[transportation applications] license_orientation DL : 0: 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-

[transportation applications] TEST1 DL : 0: 停车场管理系统：停车场拥有M个车位和一条进入停车场的便道，便道上最多停放N辆汽车。汽车要想进入车位，首先进入便道等候。若有空闲车位，则停车入位，否则在便道继续等候，直至有车位空出。若便道已经停满等候的汽车，后到达的汽车只能离开，选择其他停车场。设计一个停车场管理系统，模拟停车场的运作，并统计停车场的收入。 M=30，N=5，以1小时为时间的最小单位，每小时停车费30元，每小时到达的车辆数目在0-20辆之间均匀分布，车辆停留1小时后离开的概率是25 ，每多停留1小时后离开概率增加25 ，4小时后一定要离开。一天以24小时计算。-Parking Management System: parking spaces and one with M the sidewalk into the parking lot, parked up on the sidewalk N cars. To enter the car parking spaces, first into the pavement waiting. If free parking, the parking into place, or in the sidewalk to wait until the needed spot. If the sidewalk is already full of parked cars waiting, after the arrival of the vehicle to leave, choose a parking lot. Designing a car park management systems, simulation parking operations and parking revenue statistics. M = 30, N = 5, with 1 hour smallest unit of time, the hourly parking fee $ 30 per hour reach the number of vehicles in the 0-20 evenly distributed between the vehicles, the vehicle left the residence after 1 hour the probability is 25 , 1 hour per stay away more than 25 probability, 4 hours after going to leave. One day in 24-hour calculation.
