The invention relates to the technical field of traffic management equipment. A device disclosed by the invention is composed of three steering indicator lamps installed at the top end of each runningvehicle, a data acquisition camera installed on the side edge of an intersection and a front-end processor connected behind the camera. The data acquisition camera installed on the side edge of the intersection normally outputs standard video signals, and leads out red (R), green (G) and blue (B) color component signals and sends the color component signals to the front-end signal processing part. The front-end signal processing part carries out useless signal elimination on the shot image by analyzing the image signal waveform on each row of scanning lines in the shot video image, measures avehicle of which the steering lamp is turned on to calculate the distance between the vehicle and the stop line, identifies the color of the steering lamp turned on by the vehicle, judges the turningrequirement, sorts the information of the vehicle approaching the intersection and sends the information to an intersection computer host for intelligent management.

    技术领域:交通管理设备本装置是由每辆行驶车辆顶端安装的三只转向指示灯、路口侧边安装的数据采集摄像机及连接在摄像机之后的前端处理器三部分所组成。在路口侧边安装的数据采集摄像机除正常输出标准视频信号之外还从机内分别引出红(R)、绿(G)、兰(B)三种彩色分量信号送入前端信号处理部分。前端信号处理部分通过对所摄的视频图像中各行扫描线上图像信号波形进行分析可以对所摄图像进行无用信号排除;对打开转向灯的车辆进行测量计算出该车辆距停车线距离;识别车辆所开转向灯的颜色,进而判定出其转向要求,再将驶近路口车辆信息整理后送入路口计算机主机进行智能化管理。
