The invention discloses a vehicle overspeed automatic detection method and system based on a thunder-vision all-in-one machine. Obtaining timestamp information and vehicle distance information of a target vehicle corresponding to each frame according to the radar detection data; obtaining a plurality of vehicle speeds according to the timestamp information and the vehicle distance information of the target vehicle corresponding to the adjacent frames; sorting the plurality of vehicle speeds to obtain a plurality of preprocessed vehicle speeds, and averaging the preprocessed vehicle speeds to obtain a target speed of the target vehicle; if the target speed is greater than the threshold speed, determining that the target vehicle is an overspeed vehicle, and obtaining vehicle position center point coordinates of the overspeed vehicle according to radar detection data; performing coordinate system matrix conversion on the coordinates of the vehicle position center point to obtain the coordinates of the vehicle position center point under an image coordinate system; and according to the video image data, obtaining an overspeed vehicle image taking the vehicle position center point coordinate in the image coordinate system as a center, and carrying out vehicle identification on the overspeed vehicle image to obtain vehicle information of the overspeed vehicle.

    本申请公开一种基于雷视一体机的车辆超速自动检测方法以及系统。根据雷达探测数据,获得每一帧对应的目标车辆的时间戳信息与车辆距离信息;根据相邻帧对应的目标车辆的时间戳信息与车辆距离信息,获得多个车辆速度;对多个车辆速度进行排序,获得多个预处理车辆速度进行均值处理,获得目标车辆的目标速度;若目标速度大于阈值速度,则目标车辆为超速车辆,根据雷达探测数据,获得超速车辆的车辆位置中心点坐标;对车辆位置中心点坐标进行坐标系矩阵转换,获得图像坐标系下的车辆位置中心点坐标;根据视频图像数据,获取以图像坐标系下的车辆位置中心点坐标为中心的超速车辆图像,对超速车辆图像进行车辆识别,获得超速车辆的车辆信息。
