Inspection around-aircraft method and system based on liftable trolley

Abstract

The invention discloses an inspection around-aircraft method and system based on a liftable trolley. The method comprises the steps of starting the liftable trolley to collect all-around images of allto-be-detected parts of an aircraft to be detected along a preset around-aircraft route; selecting an appropriate image sub-database for the acquired image in an image database according to the modelof the to-be-tested aircraft and the position of the to-be-tested part; and based on the image deep learning model corresponding to the selected image sub-database, carrying out damage judgment on the acquired image so as to obtain an inspection around-aircraft result of the to-be-tested aircraft according to the damage judgment result. A high-definition camera is arranged in the unmanned liftable trolley; the upper surface and the lower surface of the aircraft can be comprehensively shot, a corresponding winding inspection item image deep learning model library is established, shot images can be correspondingly processed and judged, inspection is more accurate, comprehensive and intelligent, meanwhile, the working intensity of aircraft maintenance personnel is reduced, the inspection time is shortened, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of inspection and detection of civil aviation aircraft, in particular to an inspection method and system based on a liftable trolley. Background technique [0002] When the aircraft is flying at high speed in the air, the skin and outer windows of the aircraft and the particles in the air, including liquids, solids, gases and various industrial waste gases, will continuously generate friction or corrosion, leaving marks, resulting in slight changes in the aircraft's body structure. In severe cases, failures such as wear and cracks will occur on the aircraft, which will affect flight safety. Therefore, it is necessary for maintenance personnel to conduct a walk-around inspection of the aircraft, collect corresponding aircraft scratch images for analysis and processing, understand the overall state of the aircraft, check whether the aircraft's appearance is suitable for continued flight, and confirm the safety...

AI Technical Summary

Problems solved by technology

However, on the one hand, the visual inspection is limited by the height of the crew, and only the lower part of the aircraft can be inspected, and the upper surface of the aircraft becomes a blind spot for visual inspection.

And during the inspection process, due to human negligence of the inspectors and light, it may not be possible to find small cracks or other signs of accidents in time.

On the other hand, detour inspections in bad weather or climate (such as high temperature and severe cold) will reduce the work efficiency of detour inspection personnel and increase the work intensity of detour inspection personnel

Whether it is the crew or the pilot, there is a relatively strict time limit for the detour inspection. Multi-object inspection within the limited time will also lead to the possibility of missed inspections, especially the rush inspection during the busy flight period will increase the number of missed inspections. The possibility of inspection and missed inspection will lead to the generation of flight safety hazards
