Structural light-based airport runway foreign body detection system

Abstract

The present invention discloses a structural light-based airport runway foreign body detection system. The system includes a detection vehicle as well as a line laser module, an image acquisition module and a computer control and processing module which are all mounted on the detection vehicle; the line laser module is mounted at the rear end of the detection vehicle and projects a structural light plane to the surface of a runway with a certain attitude so that the structural light plane can form a structural light strip; the image acquisition module is located at the rear end of the test vehicle and is located at the same plane with the line laser module, wherein the plane is perpendicular to the surface of the runway; the image acquisition module acquires the light strip image of the surface of the runway with a certain attitude and transmits light strip image data to a computer; and the computer control and processing module is located inside the detection vehicle, controls the image acquisition module to acquire the light strip image of the surface of the runway, and processes the light strip image data in real time through related software and judges whether a foreign body exists on the runway.

Description

technical field [0001] The invention provides a detection system, relates to an airport runway foreign object detection system based on structured light, and belongs to the technical field of airport runway foreign object detection based on computer vision. Background technique [0002] Foreign Object Debris (FOD) on an airport runway refers to a foreign object, that is, some foreign substance, debris or object that may damage or destroy an aircraft or system. FOD poses a serious threat to the safety of aircraft takeoff and landing. Many cases have shown that the engine of the aircraft is easy to inhale foreign objects on the airport runway. A small piece of plastic sheeting or a small bird inhaling the engine may cause an air stop. A small screw or a sharp object such as a piece of metal may puncture the tire. Cause blasting, and the rubber fragments produced may damage the aircraft body or important parts, such as fuel tanks, hydraulic pipes, etc. According to conservati...

Problems solved by technology

They have their own advantages and disadvantages: millimeter-wave radar has the advantages of high-precision angle measurement and ranging, but the signal processing is complex and the target feature information is less

The disadvantage of this system is that the system needs to be composed of multi-channel visible light and infrared CCD, Internet camera and laser range finder, etc., the system cost is high, and the airport flight is suspended in bad weather. At this time, there is no detection of foreign objects on the airport runway. Practical meaning
