Application analysis of 3D high-precision scene construction technology in virtual r eality interaction design and development

由于传统场景搭建技术对真实场景的还原度较低,文章针对三维高精度场景搭建技术在虚拟现实交互设计研发中的应用展开分析。本研究采集真实场景矢量数据并进行预处理,通过建模与渲染技术搭建三维高精度场景,基于语音识别技术实现虚拟现实交互方式。通过本文所提技术搭建的虚拟手术室场景模拟手术过程,该场景下手术器械的移动轨迹一直处于平滑稳定状态,对语音文件的音素识别错误率为1.29%、词汇识别错误率为1.02%,验证三维高精度场景搭建技术在虚拟现实交互设计研发中具有较好的应用效果。

Due to the low reduction degree of traditional scene construction technology to real scenes,the application of three-dimensional high-precision scene construction technology in the research and development of virtual reality interaction design is analyzed.In this study,the vector data of the real scene was collected and preprocessed,and the 3D high-precision scene was built through modeling and rendering technology,and the design of virtual reality interaction mode was realized based on speech recognition technology.Through the proposed technology in this paper to build a virtual operating room scene simulation operation process,the scene of surgical instruments moving trajectory has been in a smooth and stable state,the voice file phoneme recognition error rate is 1.29%,vocabulary recognition error rate is 1.02%,and verify 3D high precision scene building technology in virtual reality interaction design development has a good application effect.
