Abstract

The invention discloses a digital enterprise lean manufacturing interactive application (DELMIA)-environment-based virtual human control method for an immersive virtual maintenance simulation system. The method comprises the following six main steps of: 1, setting the data output of motion capture software; (2) performing motion capture, and transmitting data in real time by using the software ofmotion capture equipment; 3, receiving and temporarily storing motion data output by the motion capture software; (4) calculating the motion data; 5, endowing DELMIA virtual simulation software with the converted motion data in an Automation application programming interface (API) way; and 6, repeating the steps 2 to 5. The immersive virtual maintenance simulation system is constructed by the DELMIA virtual simulation software and a wireless optical fiber motion capture system adopting ShapeWarp, corresponding researches on interface design algorithms for the DELMIA virtual simulation software and the wireless optical fiber motion capture system adopting the ShapeWarp by utilizing an Automation secondary development technology provided by the DELMIA virtual simulation software are made torealize the motion control of real maintenance data acquired by the motion capture system over virtual humans in the virtual simulation software DELMIA, and a new scheme for controlling the virtual humans under a DELMIA environment is provided to realize the fusion of a user and a virtual environment.

Description

technical field [0001] The present invention is based on the virtual human control method of the immersive virtual maintenance simulation system under the DELMIA environment. Specifically, it is an immersive virtual simulation system provided by DELMIA software to simulate human body movements and behaviors, making users feel like they are in real life. The virtual product is also operated in real time on the product, so that the maintenance problems in the design can be found in time before the physical prototype is produced. It belongs to the technical field of virtual reality technology-assisted system maintenance. Background technique [0002] Immersive virtual simulation means that designers can "virtually" maintain products in an immersive virtual maintenance environment, and can timely discover maintenance problems in the design before the production of physical prototypes, analyze maintainability design, and formulate maintenance procedures. Validate and assist maint...

AI Technical Summary

Problems solved by technology

On the one hand, virtual maintenance software has strong simulation and analysis functions, but the human motion modeling work is cumbersome and the edited movements are not realistic enough; on the other hand, motion capture systems are only used in special fields such as animation production. The supporting software generally can only use 3D animation to reproduce the trajectory of real people, but does not have other analysis and processing functions, nor can it load CAD product data
