基于VR技术的室内物体可视化建模设计

Visual Modeling Design of Indoor Objects Based on VR Technology

室内物体建模过程中,每一项建模参数的确定与调整都需要经过大量计算,使得室内物体可视化建模时间较长。为了提高建模效率,提出基于虚拟现实(Virtual Reality,VR)技术的室内物体可视化建模方法。通过标定后的三维扫描仪和相机采集室内物体图像,并通过二值化处理提取物体边界轮廓,依据双目感知原理,建立以加强真实感为核心的可视化视觉通道,运用VR技术构建三维虚拟场景,在虚拟场景内运用多层次细节模型构建室内物体3D几何模型,并通过VR交互处理实现对建模参数的智能调整,结合缓慢剔除算法和体绘制方法对模型进行渲染处理,完成物体可视化建模。实验结果表明该方法每个建模阶段平均耗时3 s,总建模时间为18 s,满足了可视化建模时效性要求。

In the process of indoor object modeling,the determination and adjustment of each modeling parameter requires a lot of calculation,which makes the visual modeling of indoor objects take a long time.In order to improve modeling efficiency,a visual modeling method of indoor objects based on Virtual Reality(VR)technology is proposed.After calibration,3D scanner and camera are used to capture indoor object images,and binary processing is used to extract object boundary contour.According to the principle of binocular perception,a visual channel with the core of enhancing realism is established.Use VR technology to build a 3D virtual scene,use multi-level detail models to build 3D geometric models of indoor objects in the virtual scene,and achieve intelligent adjustment of modeling parameters through VR interactive processing.Combining the slow culling algorithm and volume rendering method,the model is rendered to complete the object visualization modeling.The experimental results show that the average time of each modeling phase is 3 s,and the total modeling time is 18 s,which meets the timeliness requirements of visual modeling.
