Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] The present invention proposes a method for drawing an airport label by a synthetic visual system, and the specific steps of the method are as follows:

[0016] Step (1), obtain aircraft attitude, position and heading information from the aircraft's inertial reference system, GPS receiver and flight management computer respectively through the aircraft bus.

[0017] According to the obtained current attitude, position and heading information of the aircraft, the airport information within a certain range in front of the aircraft is retrieved through the navigation database, and transmitted to the synthetic vision system through the aircraft bus. The synthetic vision system belongs to the prior art. The system can provide the pilot with a view of the terrain outside the aircraft and improve the pilot's perception of the surrounding envir...

Abstract

The invention relates to a method for drawing an airport label in a synthetic vision system. The method comprises the following steps: acquiring a flying posture, position and heading of an aircraft according to a sensor on the aircraft, searching airport information in a set range of the aircraft, transmitting the information to the synthetic vision system on the aircraft, and converting the searched airport information to three-dimensional scene coordinates; arranging a Billboard on the airport three-dimensional scene coordinates to enable a normal vector of the Billboard to always point to the aircraft, and then sticking an airport label position draw onto the Billboard; when the aircraft changes the posture and the heading in real time, enabling the Billboard to always point to the aircraft by adjusting the normal vector of the Billboard to enable a pilot to clearly sense the position of the airport on the synthetic vision system. Through adoption of the method, the pilot can quick, accurately and clearly sense the airport label from the synthetic vision system, so that the possibility that the pilot misses a target airport or an alternate airport is lowered, and the pilot workload is reduced.

Description

technical field [0001] The invention relates to a method for drawing an airport label by a synthetic visual system, and belongs to the technical field of aircraft navigation and positioning. Background technique [0002] With the opening of my country's low-altitude airspace, there will be more and more private jets. As a result, the use of the airport is becoming more and more busy. If there is another bad weather, more aircraft will need to temporarily decide to land at the alternate airport. At this time, the pilot must clearly understand the airport conditions around the aircraft. At present, the synthetic vision system of the aircraft is mainly used to search the surrounding airports, but the synthetic vision system in the prior art only draws terrain information, and the pilot also needs to check the navigation information to determine the information of the destination airport and the alternate airport. This increases the pilot's workload, and it is easy to miss the ...
