摘要
为了提高城市空间环境设计的合理性,改善三维视觉成像效果,提出一种基于VR激光虚拟技术的城市空间环境设计方法。在虚拟现实场景中通过激光成像技术得到城市空间布局的实时渲染成帧画面,将城市空间环境场景数据库中的相关数据加载到VR激光成像系统中,对激光图像进行区域属性块分割和边缘轮廓特征提取,根据图像的区域分割结果进行城市空间规划,实现城市空间环境改进设计。仿真结果表明,采用该方法进行城市空间环境虚拟现实重构,成像效果逼真,城市规划的合理性较理想,城市建筑物的像素视差较小。
In order to improve the rationality of city space environment design,improve the imaging effect of 3 D vision,a method is proposed to design the city space environment VR laser based on virtual technology,the virtual reality scene in real-time rendering by laser imaging technology is used to get the city space layout into a picture frame of the database,the city space environment in the scene data is loaded into the VR laser imaging system.Region attribute block segmentation and edge contour feature extraction are used for laser image,the city space planning is carried out based on regional image segmentation results,to improve the design of city space environment.The simulation results show that using the method of city space environment virtual reality reconstruction have image lifelike,city planning ideal,the elevation information measurement precision of city buildings,the smaller pixel disparity.
