Method and system for guiding airplane docking and identifying airplane type based on machine vision

Abstract

The invention discloses a method and a system for guiding airplane docking and identifying an airplane type based on machine vision. The method comprises the steps of S1, setting an airplane docking scene, dividing a monitored scene into different information processing functional areas; S2, image pre-processing for performing preprocessing on a photographed image; S3, capturing the airplane, confirming a fact that the airplane appears in the image through identifying the engine and the front wheel of the airplane in the image; S4, tracking the airplane, performing continuous tracking real-time updating on the captured images of the engine and the front wheel of the airplane; S5, positioning the airplane, realizing real-time positioning on the airplane and accurately determining the deviation degree of the airplane relative to a guiding line and a distance between the airplane and a stopping line; and S6, displaying information, outputting and displaying the deviation degree of the airplane relative to the guiding line and the distance between the airplane and the stopping line in the step S5. The method and the system have advantages of realizing airplane docking guiding in a visual manner and effectively accuracy in an airplane docking process.

Description

Technical field [0001] The invention relates to a method for aircraft docking guidance and model recognition, in particular to a method and system for aircraft docking guidance and model recognition based on machine vision. Background technique [0002] Aircraft docking berth guidance refers to the process of guiding the arriving aircraft from the end of the taxiway to the parking position on the apron and parking accurately. The purpose of aircraft berth guidance is to ensure the safe and accurate parking of docked aircraft, which can facilitate the accurate docking of aircraft with various ground handling interfaces, and enable the boarding bridge to effectively dock the aircraft doors, thereby improving airport operation efficiency and safety. [0003] Automatic aircraft parking guidance systems are mainly divided into different types of sensors used: [0004] (1) Buried coils; (2) Laser scanning distance measurement; (3) Visual perception. [0005] Since laser scanning ranging an...
