Navigation airport low-altitude navigation chart based on AR display technology and implementation system thereof

Abstract

The invention discloses a navigation airport low-altitude navigation chart based on an AR display technology and an implementation system thereof. When the aircraft is close to an airport or takes offfrom the airport, the navigation airport low-altitude navigation map is displayed in a visual screen with AR glasses worn on the head, and the navigation airport low-altitude navigation map display comprises a three-dimensional geographic space and a navigation map element three-dimensional data model associated with geographic data of the three-dimensional geographic space; the aerograph elementthree-dimensional data model comprises: an aerograph element three-dimensional data model, the system comprises a flight program data model, an airport data model, an obstacle data model, a conduction device data model and a special ground object data model. The flight program data model is a continuous navigation channel and track line displayed on a descending navigation channel or an ascendingnavigation channel of an airfield runway from the upper limit of a low-altitude three-dimensional geographic space of an aircraft, and a hollow-square-shaped closed transparent cavity is formed around the navigation channel and the track line. According to the invention, visual approach and departure three-dimensional chart elements and attribute information are provided for pilots as flight guidance.

Description

technical field [0001] The invention belongs to the technical field of general aviation, and relates to a low-altitude aerial chart of a general aviation airport based on AR display technology and a system for its realization. Background technique [0002] At present, there is no complete professional chart for general aviation. The "National General Aviation Airport Information Compilation" only contains the airport plan, and the visual flight chart does not include flight procedures and other important chart elements and navigation information, and there is no electronic flight bag for low-altitude charts. (EFB) and 3D products. [0003] At present, the electronic flight bag (EFB) or "electronic chart" and "flight procedure" used by civil aviation pilots are essentially "electronic paper charts". Although it is a professional chart software, the drawing method of the chart is exactly the same as that of the paper version. The most important flight procedures (including in...

AI Technical Summary

Problems solved by technology

Although it is a professional chart software, the drawing method of the chart is exactly the same as that of the paper version. The most important flight procedures (including instrument flight procedures and visual flight procedures) are two-dimensional and divided into: Horizontal section diagram and vertical section diagram, part of the chart is not drawn to scale due to reasons such as the chart size, part of the flight procedures and route navigation points, and each chart is stored in a separate file, there is : Retrieval of navigation information needs to be manually clicked one by one, the display screen is easy to reflect light, and the pilot needs to slide the screen by hand, which is inconvenient to operate. Different runway takeoff and landing directions and different navigation methods are divided into different chart displays, which distracts the pilot. In flight control and monitoring, the signal of the built-in positioning and navigation module is easily interrupted
