Description

technical field [0001] The invention relates to the technical field of virtual maintenance behavior synthesis, in particular to a method and system for synthesizing virtual maintenance behavior based on functional parts of a human body. Background technique [0002] In recent years, virtual simulation technology has shown a blowout development, and its application fields are very wide, and it has been widely used in equipment design. In maintainability design work, the most common application purpose of virtual maintenance simulation is maintainability training and maintenance evaluation. Virtual maintenance simulation is realized in two ways: immersive and non-immersive. Immersive virtual maintenance is a human-in-the-loop method. By setting up maintenance scenes in advance, maintenance personnel can wear motion capture equipment to complete specific maintenance tasks and collect relevant data in the maintenance scene. Non-immersive virtual maintenance refers to the use o...

Problems solved by technology

On the one hand, the maintenance scene where the maintenance personnel are located may be difficult to set up (such as a weightless environment or a complex multi-layer structure). When wearing an optical device, the cable will restrict the maintenance action, and it may not be possible to complete large-angle turns and direction changes; when wearing optical equipment, due to the limitation of the camera installation position, the maintenance personnel can only move in a limited area and cannot complete large-area maintenance. Task

Maintenance simulation using a non-immersive method can well overcome the above defects, but this method also has its own shortcomings. For example, when complex maintenance actions need to be completed, the adjustment process of the action is very complicated. The level requirements are very high, and even if the adjustment of the action is completed, the simulation results may be severely distorted, and the simulation efficiency is low
