摘要
城市的交通路口往往是交通管理的重点难点,传统的基于图像处理和模式识别技术的交通流信息检测系统,由于其安装简单、获取的信息丰富、便于维护等优点,已经成为交通检测的主要发展方向,但在实际应用中还存在许多不足之处。提出了一种新的车辆检测技术,利用地面三维激光扫描系统获取道路车流量点云数据,从而对车流量进行检测,实现全天候交通信号控制系统适应不同的交通流,优化交通路口管理,提高道路通行能力。
The urban traffic intersections are usually the focus and nodus of the traffic management.As the advantage of the simple installation and access to the rich-information and easy maintenance,the traditional traffic flow information detection system based on image processing and Pattern Recognition has been the main trends of the traffic detection.However,there are many shortcomings in practice.This paper proposed a new vehicle detection to detect the traffic flow by the LiDAR to get the point cloud data of the vehicles flow,which could help the traffic signal control system adapt to the different traffic flow and optimized the management of the traffic intersection.
