The invention provides a high-precision positioning method for road traffic potential safety hazards, and the method comprises the steps: constructing a dynamic coordinate system based on a laser radar according to the induction range of the laser radar; acquiring traffic image data according to a camera device, and performing hidden danger positioning on the traffic image data through a traffic hidden danger recognition model; determining traffic hidden danger real-time coordinate data according to hidden danger positioning and the dynamic coordinate system; and according to the real-time coordinate data, determining the relative position data and the safe distance data of the traffic hidden danger distance vehicle. According to the invention, when the vehicle runs, based on real-time detection and judgment of the potential safety hazard, the potential safety hazard area is accurately positioned through judgment of the potential safety hazard, and the relative safe position and the distance measurement safe position are determined through positioning of the potential safety hazard, so that a user is accurately reminded.

    本发明提供了一种道路交通安全隐患的高精度定位方法,包括:根据激光雷达的感应范围,构建基于激光雷达的动态坐标系;根据摄像装置获取交通图像数据,将交通图像数据通过交通隐患识别模型进行隐患定位;根据隐患定位和动态坐标系,确定交通隐患实时坐标数据;根据实时坐标数据,确定交通隐患距离车辆的相对位置数据和安全距离数据。本发明能够在车辆进行行驶的时候,基于实时检测和判断安全隐患,通过对安全隐患的判定,精确得对安全隐患得区域进行定位,通过对安全隐患定位,进而确定相对安全得位置和测距安全得位置,进而对用户进行精确的提醒。
