The invention relates to a vehicle type classification method based on double-laser-point cloud data analysis and traffic investigation equipment. The vehicle type classification method based on double-laser-point cloud data analysis comprises the following steps: acquiring data of vehicles: acquiring three-dimensional point clouds, instantaneous speeds and instantaneous time corresponding to the instantaneous speeds of n sections of passing vehicles by using two lasers; a high-definition camera is used for acquiring videos shot in real time, and a real-time watching tool is used for assisting verification of workers; data analysis: establishing a three-dimensional information model of the vehicle by detecting the industrial personal computer, calculating vehicle speed, vehicle flow, time headway and interval headway parameters, and analyzing through a neural network to obtain the vehicle type of the vehicle; performing data statistics and uploading: performing statistics on the data analysis result and a video shot in real time, and uploading the data analysis result and the video to a server; and data display: calling the data analysis result on the server through a display, or verifying a detection result through a video shot in real time.

    本发明涉及一种基于双激光点云数据分析的车型分类方法及交通调查设备,基于双激光点云数据分析的车型分类方法包括如下步骤:获取车辆的数据:利用两个激光器均获取所经过车辆的n个截面的三维点云、瞬时速度和瞬时速度对应的瞬时时间;利用高清摄像机获取实时拍摄的视频,用于给工人辅助验证的实时观看的工具;数据分析:通过检测工控机构建车辆的三维信息模型,计算车速、车流量、车头时距和车头间距参数,并通过神经网络分析得出车辆的车型;数据统计及上传:将所述数据分析结果及实时拍摄的视频进项统计并上传至服务器;数据显示:通过显示器调用所述服务器上的所述数据分析结果,或通过实时拍摄的视频验证检测结果。
