基于大数据技术的虚拟现实场景展示系统设计

Design of Virtual Reality Scene Display System Based on Big Data Technology

传统的虚拟现实场景展示系统所使用的数据,去噪后仍存在较多噪声点和错误空间点,导致场景三维重建偏差较大和重建时间较长,为此提出基于大数据技术的虚拟现实场景展示系统。硬件设计方面,优化数据采集器,确保场景数据的高集成度,设计存储器外围传感电路,扩增存储容量,将采集的数据发送给PC机;软件设计方面,利用大数据技术进行数据分类,提取场景特征点,生成轮廓纹理的高质量视差图,将像素点转换为三维空间点,并对其进行颜色渲染和去噪精简,以此实现虚拟现实场景展示。实验结果表明,该系统降低了场景三维重建偏差的同时缩短了重建时间,提升了虚拟现实场景展示效果。

In the traditional virtual reality scene display system,there are still many noise points and error space points in the data after denoising,which leads to large deviation and long reconstruction time of 3D reconstruction for the scene.Therefore,a virtual reality scene display system based on big data technology is proposed.In terms of hardware design,the data collector is optimized to ensure the high integration of scene data;the peripheral sensing circuit of memory is designed to amplify the storage capacity and send the collected data to PC.In terms of software design,big data technology is used to classify data,extract scene feature points,generate high-quality parallax map of contour texture,convert pixel points into three-dimensional space points,and carry out color rendering and denoising for simplification to achieve virtual reality scene display.The experimental results show that the system reduces the deviation of 3D scene reconstruction,shortens the reconstruction time,and improves the display effect of virtual reality scene.
