Three-Dimensional Visual Monitoring System of Airport Runway Based on Digital Twins
In response to the requirements of promoting the transformation and upgrading of airports in the Action Outline for Promoting the Construction of Four Types of Airports issued by the Civil Aviation Administration in 2020,and in order to solve the problems of low efficiency of runway monitoring in traditional artificial airports and the ina-bility to achieve all-round real-time monitoring of airport runways and real-time communication of monitoring data,in this paper,the airport runway monitoring architecture is designed based on digital twinning technology.Through the use of 3D visualization technology,the airport runway sensors and monitors are summarized into the platform data for processing and mapping in the virtual model.The digital model is used to restore the airport 3D model,and the light-weight of the airport 3D model is studied.At the same time,the aircraft trajectory is real-time located and mapped through optical fiber sensors.The virtual twin is generated to map the real-time state of the airport runway to the vir-tual space,and realize the virtual and real mapping of the digital twin.So as to meet the requirements of multi-dimen-sional observation,full data analysis and visualization of the airport runway,and visually and dynamically display the real-time status of the airport runway.
