Abstract

The embodiments of the invention provide a civil airport barrier restriction map three-dimensional modeling method and apparatus under a terrain constraint condition, and electronic equipment. The civil airport barrier restriction map three-dimensional modeling method under a terrain constraint condition includes the steps: based on a runway of an airport to be researched, establishing a three-dimensional coordinate system, and establishing a preliminary model for an airport barrier restriction map; according to the relationship between each restriction surface in the preliminary model, determining the main establishment points of the restriction surfaces, and according to definition parameters of the restriction surfaces and the altitude difference of the runway, calculating the coordinate values of the establishment points in the three-dimensional coordinate system under constraint of the terrain condition; and according to the coordinate values of the establishment points, obtaininga three-dimensional model of the restriction surfaces in the three-dimensional coordinate system, so as to further obtain a three-dimensional model of the airport barrier restriction map in the three-dimensional coordinate system. The civil airport barrier restriction map three-dimensional modeling method under a terrain constraint condition establishes the restriction surface model based on thethree-dimensional coordinate system, avoids the defect of the barrier restriction map in a two-dimensional mode in the prior art is hard to be visually understood and applied, and can improve accuracyof the airport barrier restriction map by using the practical altitude data to perform correction so as to be more close to the site environment.

Description

technical field [0001] This application relates to the technical field of three-dimensional modeling, in particular, to a civil airport obstacle restriction under terrain constraints Figure three Dimensional modeling method, device and electronic equipment. Background technique [0002] The clearance status of civil airports plays a decisive role in ensuring the safety of aircraft takeoff and landing, and is very important to the safe and efficient operation of the airport. The airport obstacle restriction map is an important basis for the airport management organization to manage clearance obstacle restrictions. At present, the airport obstacle restriction map is drawn based on the international standard <Convention on International Civil Aviation - Annex 14 Airport> and the domestic civil aviation industry standard <Technical Standards for Civil Airport Flight Areas> (MH 5001-2013). In the above-mentioned standards, the civil airport obstacle restriction map ...

AI Technical Summary

Problems solved by technology

Because the delineation of the eight obstacle-limiting surfaces is carried out with the entrances at both ends of the runway as the starting point, the elevation at the entrances at both ends of the runway has a great influence on the delineation range of the obstacle-limiting surfaces, while in the prior art When modeling the obstacle restriction map of civil airports, the terrain factors of the runway are not differentiated, so the deviation of the obstacle restriction surface range is caused, which in turn leads to the inaccuracy of the obstacle restriction map of civil airports. Considering the three-dimensional space factors, Reduce the accuracy of the environmental range of the protected airspace around the airport, and reduce the safety margin of the airport operation

At the same time, it may cause the clearance of super-high obstacles on the land around the airport and the unreasonable situation of land layout
