基于增强现实的三维建筑物模型移动可视化系统
|
摘要
针对传统虚拟现实的三维数据可视化存在专业性强、交互复杂、不够直观等局限问题,以户外三维建筑物为研究对象,构建了测绘的定位定姿技术与计算机视觉的边缘跟踪技术相结合的增强现实混合跟踪技术,建立了基于增强现实的三维建筑物模型移动可视化系统。在大范围数据采集基础上的三维模型数据增量更新模式中,应用本系统开展外业核查,验证了技术的可行性。
To overcome the limitations in traditional VR-based three-dimensional data visualization, such as high specialization, complex interaction and low perception, an AR-based 3 D building mobile visualization system is developed by means of AR hybrid tracking technology combining the positioning technology and the edge tracking technology of computer vision. In the incremental update mode of 3 D model data with the large-scale data collection produced in advance, the mobile application is carried out in the field to verify the feasibility of the technology.
