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.
