Problems solved by technology

However, relying on machine vision systems alone is difficult to provide complete navigation guidance with high reliability
Therefore, the automatic take-off and landing technology that relies solely on the machine vision system to guide the aircraft has great reliability problems, which prevents it from being widely developed and applied like the automatic driving of cars.

Embodiment Construction

[0015] As mentioned above, the existing aircraft automatic navigation guidance technology has the following problems:

[0016] 1) The current blind landing guidance technology requires the installation of special navigation facilities on the ground to support the landing requirements of high precision and reliability. This technology relies heavily on the performance of ground facilities;

[0017] 2) When the weather conditions are poor, the visibility of the aircraft is low during take-off and landing, and the crew's situational awareness of the surrounding environment is poor, which is likely to cause safety accidents;

[0018] 3) Since the application of machine vision itself has certain defects (especially in terms of reliability), it is difficult to achieve high-reliability navigation guidance solely relying on this technology.

[0019] Therefore, the solution disclosed in this application is based on the existing traditional navigation and guidance system, by combining i...

Abstract

The application relates to a flight combination guidance system integrated with machine vision, the system includes: a legacy navigation system configured to determine a position of an aircraft and receive a guidance signal from the ground to provide legacy guidance information; a visual navigation system which is configured to collect image data related to an airport and perform image recognition on the image data to generate runway result information; a data fusion and guidance system which is configured to receive the traditional guidance information from the traditional navigation system and the runway result information from the visual navigation system and perform data fusion on the information; and an automatic flight control system which is configured to generate a corresponding flight guidance instruction according to the fused data from the data fusion and guidance system.

Description

technical field [0001] The application relates to the field of flight guidance for civil aircraft. More specifically, it relates to a flight combined guidance system, method and medium integrated with a machine vision system. Background technique [0002] At present, during the automatic take-off and landing process of civil aircraft, it mainly relies on various airborne systems such as flight management system, automatic flight control system, instrument landing system (ILS), global satellite landing (GLS) system, etc. During the automatic flight during the take-off phase, the flight crew still relies on the crew to manually control the flight. The above-mentioned onboard systems only provide reference data. In the approach and landing phase, it can be guided by ILS / GLS and the flight tube landing system (FLS), and the aircraft equipped with the automatic landing system can already guide the aircraft to achieve automatic landing. However, the current automatic take-off an...
