Problems solved by technology

Due to the huge structure of the aircraft, it will take a lot of time for the inspectors, especially the inspection of the top of the fuselage, which usually requires other mechanical auxiliary equipment to realize the inspection, which seriously reduces the maintenance and inspection efficiency of the fuselage and increases Due to the labor intensity of the inspectors, the inspection of the top of the fuselage by the auxiliary equipment may also cause accidental scratches / damages to the fuselage; in recent years, with the vigorous development of civil aviation and the wide application of artificial intelligence technology, traditional artificial The visual inspection method can no longer meet the requirements of rapid inspection of the aircraft fuselage
Therefore, the traditional aircraft fuselage inspection method has technical problems such as inconvenient inspection, heavy workload, high labor intensity, and long inspection cycle.

Abstract

The invention discloses a system and method for acquiring and managing three-dimensional data on the surface of a civil aviation aircraft fuselage, which includes a hangar. Frame, the left frame is vertically provided with a lifting chute A, and several left lifting cameras are installed in the lifting chute A from bottom to top in order to lift and slide; There are several right lifting cameras installed in the slot B from bottom to top; a horizontal chute is horizontally opened on the top frame, and several top sliding cameras are installed in the horizontal chute from left to right. The present invention collects the images taken by each camera through the three-dimensional reconstruction system, and then reconstructs the three-dimensional real-scene model of the fuselage through geometric correction, matching and combination, etc., which is convenient for inspectors to directly perform the inspection operation of the passenger aircraft fuselage on the computer system, and reduces labor intensity. Significantly improved inspection and maintenance efficiency.

Description

technical field [0001] The invention relates to the technical field of civil aviation aircraft fuselage inspection, in particular to a system and method for collecting and managing three-dimensional data on the surface of a civil aviation aircraft fuselage. Background technique [0002] The fuselage inspection of civil aviation airliners is an important part of the daily maintenance of the aircraft. The traditional aircraft fuselage inspection is mainly through manual visual inspection, that is, inspectors closely observe various positions of the aircraft fuselage and check for damage or deformation of the fuselage. Content check. Due to the huge structure of the aircraft, it will take a lot of time for the inspectors, especially the inspection of the top of the fuselage, which usually requires other mechanical auxiliary equipment to realize the inspection, which seriously reduces the maintenance and inspection efficiency of the fuselage and increases Due to the labor inten...
