example 1

[0092] Example 1. Example of asynchronous cooperative control method--disassembly of the electrical control device of a certain type of missile

[0093] For the entire disassembly process, most of the maintenance behavior simulation of virtual maintenance personnel can be completed by non-immersive animation simulation, but for some operation simulations with relatively small operating space, in order to avoid interference with the surrounding equipment, it is necessary to finely control the posture of the virtual human. Fine tune frame by frame. At this time, the use of non-immersive animation editing method is complicated and cumbersome, while the simulation method of using immersive motion capture to drive the virtual human to complete the corresponding posture adjustment is convenient and efficient.

[0094] 1) Obtain the attitude adjustment data of the virtual maintenance personnel in two steps.

example 2

[0099] Example 2. Synchronous Cooperative Control Method--Automobile Clutch Tightness Adjustment

[0100] The maintenance process of adjusting the height of the clutch pedal usually requires the maintenance personnel to lie in front of the driver's seat, use an open-ended wrench with the right hand to loosen the fixing nut of the clutch cable to the left, and press the pedal down with the left hand. It involves the synchronous and coordinated operation of the left and right hands of the maintenance personnel. During this process, the intermittent pressing of the pedal by the left hand is relatively simple and the cycle is relatively fixed. It should be possible to customize the number of cycles according to the needs of the simulation developer, so the method of non-immersive animation simulation is adopted. Realization; when the right hand is accompanied by the left palm to press the clutch pedal, operate the wrench to twist the fixed nut of the cable. The operation space of t...

Abstract

The invention discloses a virtual maintenance simulation method and device based on data fusion, relating to the field of data fusion assisted virtual simulation. The method comprises a step of decomposing a maintenance task and obtaining a maintenance behavior, a step of determining a simulation mode of the maintenance behavior according to the simulation requirement of the maintenance behavior, a step of obtaining non-immersive simulation data and immersive motion capture data according to the simulation mode of the maintenance behavior, and a step of generating a virtual maintenance behavior for the maintenance task by virtual people according to the non-immersive simulation data and immersive motion capture data. According to the embodiment of the invention, the two kinds of data sources are cooperatively controlled and synthesized to form the virtual maintenance behavior, and a purpose of fast and realistic simulation can be achieved.

Description

technical field [0001] The invention relates to the field of virtual simulation assisted by data fusion, in particular to a virtual maintenance simulation method and device based on data fusion. Background technique [0002] 1. The economy and convenience of virtual maintenance simulation technology to improve product design [0003] As an important application of virtual reality technology in the field of product maintainability design, virtual maintenance simulation technology plays an important role in improving product maintainability design. In recent years, regardless of the qualitative or quantitative factors of maintainability, virtual maintenance simulation technology has corresponding technical means to provide technical support for these two important aspects. Virtual maintenance simulation technology gets rid of the dependence of maintainability analysis on physical prototypes. With the help of electronic prototypes of products, it conducts multi-round, multi-mo...
