Airport runway foreign object damage detection system

Abstract

The invention relates to an airport runway foreign object damage detection system which comprises a terminal and at least one light emitting device and at least one camera device connected to the terminal. Each light emitting device is arranged at one side of a runway and is used for emitting near infrared light to illuminate the runway to generate light spots, and a projection of a foreign object is generated when the foreign object exists on the runway covered by the light spots. Each camera device is arranged at the other side of the runway and is used for shooting the light spots on the runway to obtain an image of the light spots. The terminal is used for processing the image, obtaining position information of the foreign object when the projection of the foreign object in the image is detected, and carrying out alarming. The invention provides the airport runway foreign object damage detection system, the identification of a micro foreign object is facilitated, the sensitivity of monitoring is improved, the automatic identification of FOD is realized, problems of low accuracy and low efficiency of artificial identification of FOD are avoided, and the projection of the foreign object can be quickly and accurately captured even under a strong sunlight background or in a condition of low visibility and water or oil on the runway.

Description

technical field [0001] The invention relates to the technical field of photoelectric imaging detection, in particular to an airport runway foreign object detection system. Background technique [0002] FOD (Foreign Object Debris, foreign objects on airport runways) generally refers to certain foreign substances that may damage aircraft or systems, such as various metal parts, luggage locks, trailer chains, gravel, leaves, etc. Because the aircraft is very fragile relative to foreign objects, a small screw, a small piece of metal, or a sharp stone can cause tire damage or even burst, and the burst tire fragments can damage the aircraft fuselage, engine or fuel tank, and hydraulic pipes. And other important components, causing huge economic losses, and even lead to safety accidents. Therefore, it is urgent to reduce the occurrence of FOD events. [0003] At present, there are four main systems used to detect FOD in the world, namely the Tarsier system in the UK, the FO Detec...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing FOD monitoring system can only rely on manual identification of FOD, and is easily affected by the environment, the detection efficiency is low and the accuracy rate is low, and the defects of tiny FOD cannot be accurately detected. A foreign object detection system for airport runways is provided
