Embodiment

[0042] In this embodiment, an interactive system in which a virtual human uses a wrench is taken as an example for illustration. Taking the Delmia virtual environment as the background, and using the data glove to collect the gesture and movement of the hand, the virtual hand controls the virtual wrench in the virtual environment to complete the maintenance operation.

[0043] The main functions of the interactive system are hand modeling, coordinate system conversion, and interactive feature point matching. Including three subsystems: human-computer interaction interface layer, data processing layer and database layer. Utilize the present invention to realize the interaction of this system, the steps and method of its application are as follows:

[0044] Step 1. Determine the interaction area through experiments.

[0045] According to the determined experimental plan, first mix the chalk powder and pen water at a ratio of 1:2 to obtain a suitable density of pigment; then us...

Abstract

The invention provides a virtual maintenance interaction operation method based on a virtual hand interaction feature layer model, and belongs to the technical field of virtual maintenance in maintenance design. The method includes the steps that an interaction area of a virtual hand and a maintenance tool is determined through experiments; the obtained interaction area is simplified, and virtual hand interaction feature point identification is carried out in virtual environments; virtual hand interaction is achieved through a data glove; the point where the virtual hand and the virtual maintenance tool is in contact is obtained, the obtained contact point is matched with a corresponding interaction feature point, and a coordinate system of the maintenance tool clings to a coordinate system of the virtual hand for virtual maintenance when matching is successful. By means of the method, interaction of maintenance actions in immersion virtual maintenance environments is achieved, and accordingly accuracy of virtual interaction and immersion sensing of user operations are improved.

Description

technical field [0001] The invention provides a virtual hand interaction operation method based on a virtual hand interaction feature layer model, specifically, it is a method for improving the maintainability design of products applied in virtual maintenance, which can improve system performance and reduce life cycle costs It belongs to the technical field of virtual maintenance in maintainability design. Background technique [0002] Maintainability refers to the ability of a product to maintain or restore its specified state when it is maintained according to specified procedures and methods under specified conditions and within a specified time. Improving the maintainability of products can achieve the goal of improving system performance and reducing life cycle costs. Design and analysis of maintainability is to design maintainability into products, and it is the core and key to realize maintainability requirements. [0003] The authors Zhou Dong, Huo Lin, etc. publis...
