[Graph Recognize车牌定位

Description: 车牌定位 使用时打开此例题目录下pic中的图片,然后依次单击按钮“转”、“1”、“2”、“3”、“4”和“5”,就可以实现精确的车牌定位。 具体步骤 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 used to break pic examples directory of images, and then click the button "turn", "1", "2", "3" and "4" and "5", can achieve precise positioning of the plates.

Description: PIC单片机散热器节能温度控制器的工作原理 最容易实现节能控器控制功能的改造方案就是由PIC单片机来完成控制功能,温度信号经过采样、信号调理之后再输入到单片机,在单片机中由软件编程对模拟信号进行 A∕D转换,转换为数字信号,与设定的温度相比较,得到偏差量,运用模糊控制算法对温度偏差进行模糊化和解模糊运算,控制输出量。在不同的实际温度下,通过偏差的大小来调节输出固态继电器开通与关断时间,输出占空比可调的PWM信号,控制散热器的实际加热功率,这样就实现了节能控制的目的。温度控制器原理框图如1.1。温度控制器的主要功能是由单片机进行软件的编程来实现的。 -Key words: radiator temperature SIM PIC fuzzy control automatic control energy-saving control
