Detection system and detection method for aircraft landing gear

Abstract

The invention provides a detection system and a detection method for an aircraft landing gear. The system comprises an image preprocessing module used for pre-processing a the image of a to-be-detected aircraft landing gear; an aircraft target detection module used for detecting an aircraft target in the image; a feature extraction module used for extracting the lower boundary features of the aircraft target; a landing gear suspicious region detection module used for detecting a suspicious landing gear region in the aircraft target; and a landing gear detection module used for detecting the aircraft landing gear. According to the technical scheme of the invention, whether the aircraft landing gear is laid down or not can be rapidly detected, and the engineering implementation is easily realized. The landing gear detection accuracy is high. Meanwhile, the blank of the current research in the above aspect is filled up. The system and the method provide the position and quantity information of aircraft landing gears more stably.

Description

technical field [0001] The invention mainly relates to the technical field of safety protection data processing, in particular to a detection system and method for aircraft landing gear. Background technique [0002] Before the plane lands, in order to ensure that the landing gear of the plane has been put down, in addition to the indicating equipment on the plane, an observer is also set up next to the tower to monitor with a telescope. Due to the influence of personnel factors and weather factors, this method has poor reliability. In recent years, there have been reports of flight-level accidents caused by the failure of on-board equipment and the negligence of observers. If an aircraft landing gear detection system can be installed at the airport to automatically detect whether the landing gear is lowered by machine vision, it will not only reduce flight accidents caused by observer errors, but also reduce the intensity of human labor. [0003] At present, domestic resea...

Problems solved by technology

The judgment features adopted by this method are greatly affected by the flight attitude of the aircraft, and the false alarm rate is high.

In addition, this method can only determine whether the aircraft has put down the landing gear, and cannot detect the position of the landing gear and cannot give the number of landing gear
