Method for establishing 3D digital maintenance platform of aircraft based on 3D laser scanning technology

Abstract

The invention relates to a method for establishing a digital maintenance platform of an aircraft based on a real 3D space point cloud by using a 3D laser scanning technology and a reverse modeling technology. The method disclosed by the invention comprises the following steps: firstly, obtaining point cloud data of the aircraft and parts thereof through a 3D laser scanner, and then on the basis of the point cloud data, generating the 3D digital model through data processing and reverse modeling. Based on the 3D digital model, a set of visualized operational software platforms in butt joint with the maintenance work of the aircraft is established, so that massive maintenance information can be related and integrated, and efficient convenient interactive functions can be established. The aircraft model data in the method is the real 3D point cloud information of the aircraft, and the aircraft model data can be used as maintenance information storage and maintenance interactive platforms and can complete space measurement, drawing extraction, staff training, maintenance simulation and the like in software, so that the aircraft maintenance work is greatly improved in the respects of digitalization, informatization, intelligentization and visualization.

Description

technical field [0001] The invention relates to a method for establishing a visualized and intelligent three-dimensional digital maintenance system platform for aircraft by adopting three-dimensional laser scanning technology and three-dimensional modeling technology. technical background [0002] Efficient aircraft maintenance is one of the important factors to ensure the continued safe flight of aircraft. However, aircraft has many parts, complex systems, and high safety requirements, so maintenance is difficult, with many links and complicated processes. Each maintenance requires the coordination of engineering, production, quality control, and aviation materials departments to complete. In order to ensure smooth and efficient aircraft maintenance, it is necessary to establish a unified digital and information platform. [0003] Since the 1980s, the United States and other Western powers first applied digital maintenance technology to the field of military aircraft. But...

Problems solved by technology

[0006] However, although there are researches or practices on digital maintenance of these aircrafts in China, there is a huge gap compared with foreign countries.

I personally experienced that during the maintenance process of a domestic airline, the replacement parts still use manual part numbering, manual transmission of maintenance information, and then pick up new parts from the aviation materials department, and then send the old parts to the aviation materials department after replacement. The whole process is inefficient and urgently needs to be digitized
