Construction Safety Training System For VR Buildings Based On Unity

With the rapid development of China's social economy and construction industry,safety issues have always been highly valued by the government and enterprises in high-risk industries.However,its safety accidents have become more frequent with the increasing scale of construction.On the one hand,there is insufficient supervision power.On the other hand,personnel safety training is not implemented properly,and construction personnel fail to grasp safety knowledge in a timely and effective manner.Through traditional conference-style,preaching and other safety training methods,the issue of safety education can no longer be well solved.The defects are becoming more and more prominent.Therefore,a new and more effective safety training method is urgently needed.On the basis of full analysis of virtual reality technology,this paper has studied collision detection,particle system,UGUI and virtual device development technology,and finally used Unity3 D development tools to design and implement a reusable experiential building safety training system.The system firstly has integrated with on-site acquisition and uses 3DSMax,Unity3 D and other software to reconstruct the three-dimensional virtual model of the building,and performs high-precision simulation and rendering of the virtual environment.Secondly it has used C# scripting language to achieve the interaction between the model,combined with HTC VIVE to achieve the interaction between people and architectural scenes,and finally it has recorded and analyzed the effect of the system experience to assist in on-site security management.Moreover,the scene environment set up in this paper supports secondary development and can meet more training applications.The research and implementation of the system solves the problems such as site constraints,space-time limitations and single forms in the traditional construction safety training,reduces the occurrence of safety accidents in the construction industry and improves the safety awareness of construction personnel.Training in the construction industry and other industries has important promotion functions and broad application prospects.
