Abstract

The invention discloses a ship sub-assembly auxiliary assembly system based on augmented reality, and belongs to the technical field of auxiliary assembly systems. The ship sub-assembly auxiliary assembly system based on the augmented reality comprises a cloud storage module, an engineering data module, a virtual-real fusion module and a man-machine interaction module; the cloud storage module is used for converting a created plate model into an AB model through model conversion, then establishing an xml file and storing the xml file in a network disk; the engineering data module is used for storing real-time data and UI display data generated in a ship sub-assembly assembling process; the virtual-real fusion module is used for performing three-dimensional registration by using a Vuforia augmented reality software development kit; and the man-machine interaction module is used for programming the assembly operation in the ship sub-assembly assembling process. On one hand, the acquisition of assembly information by staff can be accelerated, on the other hand, the adjustment time of a plate assembly position in the assembly process can be shortened, and the ship sub-assembly assembling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary assembly systems, in particular to an augmented reality-based auxiliary assembly system for ship team building. Background technique [0002] In order to speed up smart manufacturing and improve efficiency and production levels, most shipping companies are transferring Industry 4.0 principles to shipyards in order to transform them into brand new smart shipyards. They are exploring the application of sensing, Internet of Things (IoT), robotics, cyber-physical systems (CPS), etc. to the field of advanced shipbuilding in order to improve the efficiency of shipbuilding. Augmented reality is one of the ways to improve the efficiency of many processes in shipyards. [0003] The continuous reform and innovation in the shipbuilding field will also change the working methods of workers and related technical personnel, and the knowledge reserve and skill requirements for employees are also constantly im...
