Embodiment Construction

[0026] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings and in combination with implementation manners.

[0027] The traditional headroom analysis method usually needs to consume a lot of labor costs to map the obstacles one by one and judge the relationship with the headroom restriction surface. After the analysis is completed, it needs to consume further economic costs to carry out the removal of obstacles. The headroom analysis method is not only inefficient, but also difficult to control the cost.

[0028] Based on the above problems, the present application provides an efficient and low-cost clearance assessment scheme for airport runways, so as to shorten the average time-consuming work of non-instrument runway clearance analysis and improve work efficiency. Such as figure 1 As shown, the clearance assessment method of the airport runway of the present application includes: first, importing ...

Abstract

The invention discloses a clearance evaluation method for an airport runway. The evaluation method comprises the steps of establishing a terrain model according to terrain data of an area where an airport is located; establishing a runway model in the terrain model according to the runway parameters, and establishing a clearance limit surface model according to the runway model; establishing an artificial obstacle model in the terrain model according to the artificial obstacle parameters; and judging an interference relationship between the clearance limiting surface model and the terrain model and the artificial obstacle model so as to generate a clearance analysis result. According to the technical scheme provided by the invention, an efficient and low-cost clearance evaluation scheme for the airfield runway is provided.

Description

technical field [0001] The application relates to the field of airport construction, and more specifically, relates to a method for assessing clearance of an airport runway. Background technique [0002] Whether the airport can operate safely and effectively is closely related to the terrain and artificial structures inside and outside the site. It is necessary to put forward requirements for the airspace within a certain range along the take-off and landing routes near the airport (for example, the airspace required for aircraft take-off and climb, landing and descent, and visual circling at both ends of the runway and on both sides), that is, the clearance requirement, to ensure When flying at a low altitude for takeoff and landing, there must be no obstacles on the ground to hinder navigation and flight. Therefore, in the construction process of the airport runway, it is very important to evaluate the clearance. [0003] Traditionally, the clearance analysis steps of ai...
