Problems solved by technology

[0003] The length of a conventional civilian or military airport runway is about 2500 meters to 3000 meters, and the width is about 50-80 meters. The method of using conventional means such as people or vehicles to go to the runway for foreign object inspection on the runway faces the following problems: First, The timeliness is not high. Using people or vehicles on the runway, a single inspection may take tens of minutes or even hours, which is unacceptable for increasingly busy airports; second, the probability of missed inspections Large, there are problems such as low accuracy and high missed detection rate in human eyes'

Embodiment Construction

[0034] The present invention innovatively uses an intelligent method based on drones in the routine inspection and inspection of airports. A multi-rotor UAV with a high-speed hovering function is equipped with a high-resolution optical laser pod to conduct a full-scale and high-precision survey of the airport road surface according to the pre-planned flight path, using image stitching and restoration technology and machine training Learn the algorithm, complete the identification, positioning and marking of foreign objects on the pavement, and report the generated results to the control tower for subsequent maintenance work.

[0035] This patent has invented a UAV-based airport pavement foreign body survey system. The system consists of a multi-rotor UAV platform with high-speed flight and hovering functions, a dual-light pod device with visible light and laser ranging functions, and an integrated ground control processing terminal. In the early stage of foreign object survey...

Abstract

The invention provides an airfield pavement foreign matter recognition and positioning method, and the method comprises the steps that an unmanned plane carries out the investigation of an airfield pavement according to a preset flight path plan, collects N local airfield pavement images, and the N local airfield pavement images cover the whole airfield pavement; performing image splicing processing on the N local airfield pavement images to obtain a complete airfield pavement image; and carrying out recognition, foreign matter classification and corresponding foreign matter position information on the complete airfield pavement image by using a target detection method.

Description

technical field [0001] The invention belongs to the special technology in the field of airport logistics support and maintenance, and in particular relates to a method for identifying and locating foreign objects on an airport pavement. Background technique [0002] As one of the most critical links in the normal operation of the airport, the airport pavement is the focus of daily security and maintenance of the airport. The health of the pavement plays a vital role in the safety of the aircraft. Foreign objects on the pavement usually refer to stones, cracks, potholes, bumps and other objects that exist on the pavement due to various reasons, which will affect the smoothness of the runway and seriously threaten the safety of aircraft. During the take-off and landing phase of the aircraft, a stone with a diameter of about 0.5 cm may be sucked into the aircraft engine and cause engine failure, resulting in aircraft crash and death. Therefore, it is extremely important to con...
