Embodiment Construction

[0029] In this example, if figure 1 As shown, a foreign object detection device on an airport runway includes: an image acquisition module, a power supply module and a visual detection module;

[0030] The image acquisition module includes: a straight line laser, a USB3.0 expansion card with a PCI interface, a high-speed industrial camera, an industrial lens and a filter;

[0031] The high-speed industrial camera is set directly above the airport runway. The inline laser is used as the light source and illuminates the road at an angle of α degrees with the vertical distance of the high-speed industrial camera. The distance from the camera to the ground is 1.2 meters, and the inline laser to the ground The distance is 0.6 meters. The angle of α is generally controlled within the range of 30-45 degrees; in this embodiment, α is 30 degrees;

[0032] The in-line laser has a wavelength of 650nm and a power of 150Mw, and emits a beam of light onto the airport runway. After passing...

Abstract

The invention discloses an airport foreign object detection device and method. The device includes an image acquisition module and a visual detection module; the image acquisition module is connected with the visual detection module through a USB interface, and includes an inline laser and a USB3.0 interface with a PCI interface. Expansion card, high-speed industrial camera, lens and optical filter; the visual detection module is used to realize the detection function of foreign objects on the airport runway, including image preprocessing and feature extraction and recognition algorithms. The invention is composed of image data acquisition units installed side by side. During the detection process, the mobile device carrying the detection device travels along the runway area to be detected, and the detection width of each single pass is equal to the effective image acquisition field of view of the camera. It is processed to analyze whether there are foreign objects on the runway.

Description

technical field [0001] The invention relates to the technical field of foreign object detection and recognition in the field of image recognition, and mainly relates to a device and method for detecting foreign objects on airport runways. Background technique [0002] FOD (Foreign Object Debris) is any foreign matter that does not belong to the airport and may damage the aircraft, that is, foreign objects on the runway. FOD is divided into concrete fragments, metal fragments, rubber fragments, plastic fragments, etc. according to different materials. At present, the inspection work of domestic airport runways mainly relies on manual walking detection. During the road inspection process, the airport runway needs to be closed, which greatly reduces the flight time. Moreover, manual inspection mainly relies on the subjective ideas of workers, which is affected by human mood and spirit. The impact is large, and it is prone to missed detection. With the continuous development of...
