红绿灯识别系统
摘要:红绿灯判别系统主要针对红绿色盲及色弱者或者长期驾驶疲劳的驾驶员设计的系统,帮助他们在交通中很有效率地分辨红绿灯信号灯,从而减少一些交通事故的发生。主要采用的方法:首先通过图像采集及图像预处理的方法获源图像,用边缘跟踪中的方法确定红绿灯的各个灯的位置,把颜色形式从RGB红绿蓝颜色表示法转变成另外一种适当的表示方法,选择标准的RGB颜色表示法来得到红绿灯颜色。最后通过显示器显示红绿灯倒计时输出,倒计时到零的时候播报语音信息,提示驾驶员直接在车内观察红绿灯倒计时变化进而安全驾驶。

Abstract:Discriminant system mainly aimed at the traffic light red green color blindness and lubricious weak or driving fatigue of the driver design system for a long time, to help them in the traffic very efficiently distinguish the traffic signal lamp, thereby reducing the occurrence of some of the traffic accident. Mainly adopts the method: first by image acquisition and image preprocessing method of source image, with the edge of the edge tracing method to determine the location of the traffic lights all light, the color form from red, green, blue RGB color representation into another appropriate representation method, choose standard RGB color representation to get traffic light colors. The final output through the display shows the traffic lights countdown, countdown to zero when the warning indicator will ring one to three, countdown to tip the driver in the car directly observe traffic lights change to safe driving.
