Runway pavement monitoring device and method based on point cloud detection

Abstract

The invention relates to the technical fields of foreign body invasion monitoring and laser scanning, in particular to a runway pavement monitoring device and method based on point cloud detection. According to the technical problem to be solved that a foreign body invades an airfield runway, so that taking off and landing of a flight are threatened, the three-dimensional laser scanning technique is mainly applied in combination with a video / image recognition device, the runway pavement monitoring device arranged outside the runway in an erected mode and the method are designed for monitoring the invading foreign body appearing on the airfield runway. Meanwhile, the device and the method can also be used for accurately measuring and timely feeding back the pavement flatness of the runway. The runway pavement monitoring device based on the point cloud detection comprises the structural design among at least one laser scanning device, at least one video camera, a processor and the like. The runway pavement monitoring device and method based on the point cloud detection are applied to the field of airfield runway plane invading body monitoring.

Description

technical field [0001] The invention relates to the technical field of intrusion foreign object monitoring and laser scanning, and in particular to a runway surface monitoring device and method based on point cloud detection. 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 runway intruders is of great sig...

Problems solved by technology

Secondly, for the stable and orderly operation of the airport, the monitoring 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.
