A real-time capture method and system for a docked aircraft

Abstract

A real-time capture method and system for a docked aircraft, the method including scene setting, dividing the station apron into a capture area, a guide tracking area and a precise positioning area according to the guide line and the stop line of the docked aircraft; judging the obstacle on the station apron, by The laser scanning system scans the obstacles near the guide line to ensure the docking safety of the aircraft and avoid misjudging the obstacle as an aircraft during the guidance process; the moving object is captured, and the captured object is captured by the laser scanning system Continuously scan the area, and compare the current scanning line and the previous frame scanning parameters to determine whether there is a moving object. If the scanning parameters at the same position in the two frames before and after are greater than a threshold, it is judged that there is a moving object in the capture area; aircraft status detection, Detecting whether the captured moving object is an aircraft, and judging the docking attitude of the aircraft to determine whether to start tracking and guiding operations on the aircraft. The invention also provides a corresponding real-time capture system for docked aircraft.

Description

technical field [0001] The invention relates to aircraft positioning identification and berth guidance technology, in particular to a real-time capture method of docked aircraft based on laser three-dimensional scanning for detecting and distinguishing ground traffic control of docked aircraft at an airport so as to safely and effectively dock the aircraft 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, facilitate the accurate docking of aircraft and various ground handling interfaces, and enable the boarding bridge (PBB) to accurately dock with the aircraft door, improving the efficiency and safety of airport operations. The capture method of the berth guidance system means that after the arriving aircraft t...

Problems solved by technology

The advantages of buried induction coils are fast response, low cost, and no requirements for weather and illumination, but large errors and low anti-interference ability

At the same time, the lead wires and electronic components buried in the ground are easily crushed, the reliability is not high, the measurement accuracy is not high, the model cannot be identified, and the debuggability and maintainability are poor.

The laser scanning berth guidance system determines the position, real-time position and real-time speed of the aircraft through laser scanning ranging. It is not affected by environmental illumination and is less affected by the weather. The cost of scanning berth guidance systems is relatively high, and the frequency of laser scanning is limited, which limits the real-time and stability of guidance
