The invention discloses a road network dynamic data acquisition method for an airport flight area. The method comprises the following steps: acquiring airport flight area road network data and aircraft road network data; taking the position of a vehicle position sensor as an origin of a coordinate system and the vehicle driving direction as a y axis; establishing a dynamic coordinate system by utilizing the real-time position relationship between the basic coordinate system and the lane line; collecting vehicle position data and vehicle surrounding object position data and converting the datainto a basic coordinate system; converting the vehicle position data and the vehicle surrounding object position data into a dynamic coordinate system; converting the dynamic coordinate system into aspecified coordinate system; and carrying out compensation correction to obtain road network data. The invention also discloses a road network dynamic data acquisition system for the airport flight area. According to the method, the road network data can be dynamically updated in real time for the out-of-task emergencies in the airport flight area, and potential safety hazards caused by acquisition lag of the road network data can be avoided.

    本发明公开了一种用于机场飞行区域的路网动态数据采集方法,包括获取机场飞行区域道路路网数据和航空器路网数据;以车辆位置传感器位置为坐标系原点,车辆行驶方向为y轴;利用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;将动态坐标系转换为指定坐标系;补偿修正获得路网数据。本发明还公开了一种用于机场飞行区域的路网动态数据采集系统。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。
