摘要
交通流检测技术是实现城市交通现代化管理的核心技术之一,是智能交通系统的重要组成部分。使用基于激光扫描和视频技术融合的检测方法,利用激光扫描的测距高精度和视频信息的丰富度,使用数据坐标转换矩阵将多源交通流信息进行数据融合,实现对车辆速度,流量,和密度的高精度检测。实验表明,该方法有较高准确性和很强的鲁棒性,具备推广价值。
Traffic flow detection technology is one of the core technology to realize modem management of city transportation. It is an important component of intelligent transportation system. Based on the fusion of laser scanning and video technology detection method, we make good use of the precision of laser scanning and the richness of video information. By using data transform matrix of multi-source to reach traffic information data fusion, we can precisely detect the vehicle speed, flow, and density. Experimental result shows that, the method has high accuracy and better robustness, and can be promoted.
