A machine vision-based identification and verification method and system for docking aircraft models

Abstract

The invention provides a docking airplane model identification and verification method and system based on machine vision. The method comprises the following steps: airplane berth scene setting; airplane capturing: capturing a video image of an airplane to be berthed in the set airplane berth scene through a camera device; aircraft tracking and positioning: through continuous tracking and real-time updating of images of an airplane engine and an airplane nosewheel of the captured airplane to be berthed, realizing real-time positioning of the airplane to be berthed and accurately judging deviation degree of the airplane to be berthed with respect to a guide line; airplane identification and identity verification: carrying out model and identity verification on the captured airplane to be berthed to further ensure safe and accurate berth of the airplane to be berthed; and information displaying: outputting and displaying results of real-time positioning and the deviation degree of the airplane to be berthed with respect to the guide line as well as model and identity verification result. The invention also discloses a docking airplane model identification and verification system for the method.

Description

Technical field [0001] The invention relates to an image processing and pattern recognition used in an intelligent aircraft parking guidance system, in particular to a machine vision-based docking aircraft model recognition and verification method used for the detection, feature recognition and verification of moving objects for aircraft parking guidance And system. Background technique [0002] Aircraft 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. Automatic aircraft parking guidance systems are mainly divided into different types of sensors used...

Problems solved by technology

The Visual Aircraft Parking Guidance System (VDGS) developed by the American Honeywell Company and the Video Parking Guidance System (VDOCKS) developed by the German Siemens Company are also used in some international airports as world-leading visual guidance equipment, but these systems are not affected by weather and illuminance. High requirements, poor adaptability, and lack of intelligent information processing capabilities
