Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0030] figure 1 It is a schematic diagram of the composition principle of the detection system of the present invention. The computer vision-based foreign object detection system on airport pavement of the present invention is composed of a probe 1, a cloud platform 2, a tower 3, a cable 4, and a controller 5. The tower 3 is arranged on one side of the runway 6 of the airport. The probe 1 is installed on the platform 2 at the top of the tower 3 and facing the road surface of the runway 6. The con...

Abstract

The invention brings forward an airport foreign object debris detection system and method based on computer vision. The system includes a probe, a holder, a tower and a controller. The probe, instead of taking an entire runway pavement as a scene and detecting and processing the pavement, divides the whole area of the pavement into grids, the area is divided into a plurality of sub-areas, each sub-area belongs to a field of view with a small scope, and image sampling and processing are carried out for the sub-areas. In this way, a long-distance runway can be detected in a highly precise manner while installation within a safe distance is guaranteed. The system can automatically and quickly detect and identify airport foreign object debris, fully replaces artificial on-site investigation, and is also suitable for identifying and detecting foreign objects in other static scenes.

Description

technical field [0001] The invention relates to equipment in the field of airport safety detection, in particular to a computer vision-based foreign object detection system and method on airport pavement. Background technique [0002] A foreign object (FOD) on an airport pavement is any foreign substance, debris or object that can damage an aircraft or systems. The harm it causes will not only damage the aircraft and take the precious lives of passengers, but also bring huge economic losses and serious social impact. Therefore, it is one of the important contents of airport security inspection work to check whether FOD appears on the airport pavement at all times. [0003] At present, the common airport pavement FOD detection) methods are mainly divided into the following four types: [0004] The first is the manual detection method: the airport runway security personnel conduct regular manual inspections of the runway, and detect and remove threatening foreign objects in ...
