Problems solved by technology

Secondly, for the stable and orderly operation of the airport, the detection results should not miss the intruders on the runway, nor should we overemphasize not to miss them and make too many mistakes of misjudging safety as dangerous
Finally, the outdoor environment is different from the ideal environment of the laboratory. The ground is not a perfect plane. Weather such as fog, haze, rain and snow may cause problems such as reduced visibility and changes in the road surface environment, which must be faced in practical applications.

Abstract

The invention relates to the technical field of intrusion foreign object detection and laser scanning, in particular to a runway surface detection device and method based on laser scanning technology erected on the edge of a runway. The technical problem to be solved by the present invention is to provide a high-efficiency and accurate runway surface detection device and method based on laser scanning technology that is erected on the edge of the runway in view of the problems existing in the prior art to detect Intruders that threaten aviation safety. The present invention includes structural design between at least one laser scanner, at least one camera and processor, etc. to complete the present invention. The invention is applied to the field of detecting intruders on the runway plane of airports.

Description

technical field [0001] The invention relates to the technical field of intrusion foreign object detection and laser scanning, in particular to a runway surface detection device and method based on laser scanning technology erected on the edge of a runway. Background technique [0002] During take-off and landing, foreign objects (Foreign Object Debris, FOD) existing on the runway may pose a major threat to flight safety. Potential hazards range from damage to the fuselage, to air crashes and fatalities. Therefore, in order to ensure the safety of flights, intruders must be discovered and identified in time, and correspondingly dealt with according to their threat level. The runway intruders that threaten aviation safety can be as small as 3cm in diameter. Using manual inspection on a runway that is thousands of meters long is inefficient and the intruders are more likely to be ignored. Therefore, using an automated system to efficiently and accurately find and eliminate ru...
