Embodiment example

[0037] Use Z+Fimager5010C 3D laser scanner to scan the Airbus 340, use the reverse modeling software GeomagicStudio to model the scanned data, and finally complete the assembly in the CAD software, and establish a software platform with maintenance functions. The specific operation process as follows:

[0038] Step 1: Use the Z+Fimager5010C 3D laser scanner to scan the entire aircraft Airbus 340, including the inside and outside of the cabin. The Airbus 340 is a scanning object with a relatively complex structure. In order to collect comprehensive data, it is necessary to perform multi-station scanning on different parts of the aircraft, including engines, wings, fuselage, empennage, landing gear, cockpit, and cabin.

[0039] Step 2: Import the data acquired by the Z+Fimager5010C 3D laser scanner into the computer for processing. The process includes the following sub-steps:

[0040] ① Attaching color: The data obtained by the Z+Fimager5010C 3D laser scanner includes the 3D ...

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...
