The invention provides a road network dynamic data acquisition method and a road network dynamic data acquisition system, and belongs to the technical field of aviation, and the road network dynamic data acquisition method comprises the steps: obtaining road network data and aircraft network data of an airport flight area; taking the position of a vehicle position sensor as an original point of a coordinate system, and taking the vehicle driving direction as an x axis; establishing a dynamic coordinate system according to the real-time position relationship between the basic coordinate system and the lane line; vehicle position data and vehicle surrounding object position data are collected and converted to the basic coordinate system; converting the vehicle position data and the position data of the objects around the vehicle to a dynamic coordinate system; and converting the vehicle position data in the dynamic coordinate system and the position data of the objects around the vehicle into a specified coordinate system, and performing data correction to obtain corresponding road network data. According to the invention, road network data can be dynamically updated in real time for emergencies outside tasks in an airport flight area, and potential safety hazards caused by lagging of road network data acquisition can be avoided.

    本发明提供一种路网动态数据采集方法及路网动态数据采集系统,属于航空技术领域,路网动态数据采集方法包括获取机场飞行区域的道路路网数据和航空器路网数据;以车辆位置传感器的位置为坐标系原点,车辆行驶方向为x轴;根据基础坐标系与车道线的实时位置关系建立动态坐标系;采集车辆位置数据和车辆周围物体位置数据,并转换至基础坐标系下;将车辆位置数据和车辆周围物体位置数据转换至动态坐标系下;将动态坐标系下的车辆位置数据和车辆周围物体位置数据转换到指定坐标系下,并进行数据修正,得到对应的路网数据。本发明能对机场飞行区域内任务外突发情况实时动态更新路网数据,能避免路网数据采集滞后所带来的安全隐患。
