Docking airplane tracking and positioning method and system based on machine vision

Abstract

The invention provides a docking airplane tracking and positioning method and system based on machine vision. The method comprises the following steps: dividing a monitoring scene into different information processing function areas; capturing an airplane to be berthed in a set airplane berth scene, wherein the step further comprises background elimination, shadow elimination, territorial classification and characteristic verification; verifying whether the target is the airplane by detecting an engine and a nosewheel of the captured airplane; through continuous tracking and real-time updating of images of the engine and the nosewheel of the captured airplane, realizing real-time positioning of the airplane and judging deviation degree of the airplane with respect to a guide line; and outputting and displaying the airplane real-time positioning result and the result of the deviation degree of the airplane with respect to the guide line. The invention also discloses a docking airplane tracking and positioning system for the docking airplane tracking and positioning method based on machine vision so as to effectively realize airplane capturing, tracking and positioning in the airplane docking process and improve automation, intelligence and operation and management levels of a civil aviation airport.

Description

technical field [0001] The invention relates to an aircraft tracking and positioning method for an intelligent aircraft parking guidance system, in particular to a machine vision-based input method for aircraft parking guidance for moving object detection, tracking, feature recognition, image calibration, and object positioning. Docking aircraft tracking and positioning method and system. Background technique [0002] Aircraft parking guidance refers to the process of guiding an arriving aircraft from the end of the taxiway to the parking position on the apron and parking it accurately. The purpose of aircraft parking guidance is to ensure the safe and accurate parking of docked aircraft, to facilitate the accurate docking of aircraft and various ground handling interfaces, and to enable boarding bridges to effectively dock with aircraft doors, improving the efficiency and safety of airport operations. According to the types of sensors used, automatic aircraft parking guida...
