Problems solved by technology

However, in the actual operation of large airports, it is difficult to frequently close the runway for inspection
The lack of inspection of the runway for a long time increases the risk of accidents caused by foreign objects intruding on the runway

Abstract

The invention relates to the field of active three-dimensional detection and image recognition, in particular to a fixed road surface detection device and a fixed road surface detection method using structured light aiming at problems existing in the prior art. The fixed road surface detection method comprises the steps that: the known structure light is projected by using a detection unit in a directed manner to assist a two-dimensional camera in photographing a road surface region to be detected, a control processing unit is used for carrying out abnormal detection on photographed images according to a target detection method so as to judge whether invaders exist in the images or whether flatness of the road surface meets a requirement, and the control processing unit can send out an alarm for the discovered abnormal condition. By repeating steps of the fixed road surface detection method in all regions to be detected on the runway, the complete runway road surface detection can be achieved.

Description

technical field [0001] The invention relates to the field of active three-dimensional detection and image recognition, in particular to a fixed road surface detection device and method using structured light. Background technique [0002] The surface condition of the airport runway has a direct impact on the safety of flight takeoff and landing. The runway must be kept flat and clean, but runway damage and intrusion of foreign objects pose a serious threat to the safety of taking off and landing flights. Runway damage refers to problems such as runway weathering, cracking, breaking, and falling stones caused by various reasons such as aging and external forces. Invasive foreign objects refer to certain foreign substances, debris or objects that may damage the aircraft, such as metal parts, waterproof plastic sheets, broken stones, newspapers, bottles, luggage tags, etc. [0003] In order to ensure the safety of flight take-off and landing, the condition of the runway pavem...
