Shared laboratory virtual simulation method and system

Abstract

The invention particularly relates to a shared laboratory virtual simulation method comprising the following steps that three-dimensional modeling of laboratory equipment is performed so as to generate a corresponding three-dimensional model; a target virtual experiment scene is generated according to a selection instruction transmitted by the user; the environmental parameters of the target virtual experiment scene are adjusted according to an environment control instruction transmitted by the user; and the interactive action of the user and the three-dimensional model is acquired, the three-dimensional model, the interactive action and the corresponding experiment effect of the interactive action are simulated in the target virtual experiment scene, and an experiment report and experiment scores are generated. Physical 3D modeling of the laboratory equipment is performed and virtual simulation operation is realized so that combination of the virtual reality technology and the concrete experiment scene can be realized, the operation process and the result of the concrete experiment can be familiarized through the virtual simulation experiment and the fidelity is high; meanwhile, the intelligent control technology is fused in the virtual reality so that intelligent control of the environment can be realized, the application requirements of different experiments can be met and the range of application of the shared laboratory virtual simulation method can be enhanced.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a shared laboratory virtual simulation method and system. Background technique [0002] In 2016, the state proposed the supply-side reform of education, and the Party Central Committee made a major deployment to implement the supply-side reform. Under this new form, the state puts forward higher requirements for laboratory teaching, that is, to increase the requirements for cultivating students' experimental hands-on ability. Traditional laboratory teaching is completely dependent on experimental equipment, and teachers cannot do without experimental equipment when conducting experimental teaching. This will inevitably cause an imbalance in the supply of equipment. Therefore, under the new policy of supply-side reform, each school will Faced with many contradictions, it has brought many new challenges to experimental teaching. [0003] At the same time, with the rapid ...

AI Technical Summary

Problems solved by technology

[0004] At present, the school's experimental teaching urgently needs to establish a realistic and versatile virtual simulation experimental system to solve the problem of unbalanced supply of experimental equipment in the current stage of experimental teaching.

At this stage, the virtual simulation laboratories that have been established or are being established in various colleges and universities basically use simple texture modeling, without the development of physical engines, and the physical objects themselves do not have their own attributes. Therefore, each specific experiment needs to be done separately. Custom Development

At the same time, the experimental instruments purchased by various universities have not formed a unified size specification, which makes it difficult to form a unified specification for the model data size imported into the virtual simulation experiment system

Secondly, the existing virtual simulation experiment system in colleges and universities cannot allow all teachers and students in the laboratory to experience the same VR content at the same time

In addition, due to the high market price of helmets, most colleges and universities are unable to purchase them due to insufficient funds.
