The invention relates to the technical field of road traffic state detection, and particularly relates to a road running state detection method and system based on radar and video fusion. The method comprises the following steps: 1, carrying out the data collection of a moving target through a millimeter-wave radar and a video detector, and carrying out the preprocessing of the data; 2, converting millimeter wave radar data coordinates into video pixel coordinate system coordinates, and registering the time of the millimeter wave radar and the time of a video detector to realize mapping of a redundant vehicle region of interest of the millimeter wave radar to a video image and completing fusion of space and time; 3, performing vehicle identification on the region of interest by using a convolutional neural network obtained through historical image data training, determining the region of interest of a vehicle, and eliminating radar false alarm information; and 4, carrying out traffic statistical data calculation according to a vehicle identification result, and acquiring traffic operation state parameters in a certain time period, wherein the parameters comprise a flow, an average speed and a queuing length.
本发明涉及道路交通状态检测技术领域,尤其涉及一种基于雷达与视频融合的道路运行状态检测方法及系统,包括如下步骤:步骤一:通过毫米波雷达和视频检测器对运动目标进行数据采集,对数据进行预处理;步骤二:将毫米波雷达数据坐标转换至视频像素坐标系坐标,并将毫米波雷达与视频检测器的时间进行配准,实现毫米波雷达的冗余车辆感兴趣区域对视频图像的映射,完成空间与时间上的融合;步骤三:采用经历史图像数据训练得到的卷积神经网络对感兴趣区域进行车辆识别,确定存在车辆的感兴趣区域,剔除雷达虚警信息。步骤四:根据车辆识别结果进行交通统计数据计算,得到一定时间段内交通运行状态参数,包括流量、平均速度和排队长度。
