摘要
为优化室内空间布局,获取高精度三维立体空间结构信息,设计基于VR技术的室内空间布局三维模拟成像系统,该系统由室内空间布局平面图像采集模块、平面图像预处理模块以及VR三维模拟成像模块共同组成。图像采集模块利用鱼眼相机及相关电子学单元采集室内空间布局平面图像,经由平面图像预处理模块进行分辨率调整与模板拼接等预处理后,传输至VR三维模拟成像模块内。VR三维模拟成像模块通过平面图像进行空间标定,估算三维视觉空间提取室内三维空间中的坐标信息与颜色信息,获取室内空间布局视觉特征;构建室内空间布局三维几何模型,通过色彩与光线等渲染获取具有高级别质感的成像效果。仿真结果显示该系统成像的视觉效果与效率均优于对比系统,具有较好应用性。
A VR technology based 3D simulation imaging system for indoor space layout is designed to optimize the layout of indoor space and obtain high⁃precision 3D spatial structure information.The system is composed of plane image acquisition module,plane image preprocessing module and VR 3D simulation imaging module.In the image acquisition module,the fish⁃eye camera and related electronic units are used to collect the plane image of indoor spatial layout.After the resolution adjustment,template splicing and other preprocessing are conducted by means of the plane image preprocessing module,the images are transmitted to the VR 3D simulation imaging module.In the VR 3D simulation imaging module,the plane image is used for space calibration to estimate 3D visual space,extract coordinate information and color information in indoor 3D space,and obtain visual features of indoor spatial layout.The 3D geometric model of indoor spatial layout is constructed,and the imaging effect with high⁃level texture can be obtained by color and light rendering.The simulation results show that the visual effect and efficiency of the imaging system are better than that of the contrast system,and it has better applicability.
