An augmented reality guidance method for a product assembly process based on mobile computer

Abstract

The invention belongs to the technical field related to product assembly, and discloses an augmented reality guidance method for a product assembly process based on mobile computer. The method comprises the following steps: (1) providing a mobile computer and an assembly process augmented guidance system, and communicatively connecting the mobile computer and the assembly process augmented guidance system; (2) inputting the assembly process file of the workpiece to be assembled into the assembly process augmented guidance system, controlling the camera built in the computer to photograph the real-time video image of the workpiece assembly, and transmitting the photographed real-time video image to the assembly process augmented guidance system; (3) projecting the geometric model of the workpiece onto the video image based on the camera coordinate system, and making the projection of the geometric model of workpiece in the video image coincide with the corresponding real object image, so as to complete the calibration and registration of the camera and the real-time spatial scene. The method is easy to implement, has good flexibility and shortens time and error rate.

Description

technical field [0001] The invention belongs to the technical field related to product equipment, and more specifically relates to a mobile computer-based augmented reality guidance method for product equipment technology. Background technique [0002] Assembly refers to the combination of parts with reference to the process flow to become the final product, which is an important process in the production process. In the traditional assembly process, assemblers need to spend a lot of time reading assembly manuals or texts in order to learn and become familiar with specific assembly lines. The time cost spent in the entire assembly process is huge, and often occurs due to low learning efficiency. Lead to assembly errors or assembly quality can not meet the technical requirements and other problems. Therefore, for product manufacturers and the market, it is an important link to enhance the competitiveness of the manufacturing industry to improve and optimize the learning meth...

AI Technical Summary

Problems solved by technology

[0005] (1) The preparation work before the training guidance is relatively complicated, and it is necessary to ensure the accurate installation and normal operation of the relevant equipment in each link

[0006] (2) The above-mentioned systems all need to be mounted on the body parts of the assembler, most of which are the head and hands, there are many related components, the system is relatively large, and the requirements for the assembler themselves are relatively high

[0007] (3) The guidance process is complicated and not intuitive, and it is not friendly to the operation experience of the assembly personnel in practical applications, and lacks certain popularity and promotion
