Embodiment

[0056] Step 1, design the system framework: use the client-server parallel development mode to receive and send data, first connect the AR glasses, inertial measurement unit and industrial computer in the client to the server through wireless, and use it to integrate the assembly scene and assembly process information are transmitted to the server, and then the server is connected to the client through wireless, which is used to transmit the parsed assembly scene feature points and poses of label information to the client;

[0057] Step 2, build the assembly scene: After completing the design system framework of step 1, assemble the parts to be assembled for aviation in the parts area to be assembled in the area to be assembled, and then select label 1 in the 8 label areas arranged As the starting label, set the position of label 1 as the origin (0, 0, 0), and the initial position of the rotation is (0, 0, 0). At the same time, label 2 is displaced and rotated relative to label...

Abstract

The invention discloses an augmented reality self-positioning method based on aviation assembly, which includes designing a system framework, building an assembly scene, building a high-precision three-dimensional map of the assembly scene, building self-positioning scene information, designing a self-positioning visual system, and a timing positioning process . The invention effectively improves the operator's understanding of the task, lowers the operator's operating threshold, ensures efficient and reliable completion of the assembly task, and can also accurately locate the blank area with fewer feature points.

Description

technical field [0001] The invention relates to the technical field of self-positioning, in particular to an augmented reality self-positioning method based on aviation assembly. Background technique [0002] At present, in the assembly process of aviation complex products, there are problems such as a large number of assembly parts, many coordination relationships, and high operational complexity. Operators have to frequently switch between the virtual two-dimensional environment (computer terminal) and the real assembly environment. The assembly operation instructions cannot be integrated with the real environment, which leads to low efficiency and high error rate of traditional assembly methods, and prolongs the equipment delivery cycle. [0003] As virtual reality guided assembly has been widely used in the field of complex product assembly, but virtual reality equipment can only provide a single virtual information, there is no information in the real environment, and t...
