Real-time docking airplane capturing method and system

Abstract

The invention relates to a real-time docking airplane capturing method and system. The method comprises the steps of scene setting in which a station site is divided into a capturing area, a guiding tracking area and an accurate positioning area according to guiding and stopping lines of a docking airplane, and a laser scanning system is used to scan barriers near the guiding line to ensure the docking safety of the airplane and avoid that the barriers are determined to be the airplane by mistake in the guiding process; moving object capturing in which the laser scanning system is used to scan the capturing area continuously, a present scanning row is compared with a pre-frame scanning parameter to determine whether a moving object exists, and if the scanning parameters of two adjacent frames at the same position are greater than a threshold, it is determined that the moving object appears in the capturing area; and airplane state detection in which whether the captured moving object is the airplane is detected, and the docking state of the airplane is judged so as to determine whether to start tracking and guiding for the airplane.

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
