Abstract_Chinese:目前心墙堆石坝施工过程可视化仿真研究多是基于施工仿真结果构建的纯虚拟三维可视化, 其地形模型多根据前期勘测数据建立, 其渲染消耗资源多且不易被修改, 且与实际施工场景有很大差别．针对此问题, 将增强现实技术(AR)引入水利水电工程施工仿真中, 提出了基于增强现实的心墙堆石坝施工过程可视化仿真方法, 该方法主要解决两个方面的问题：如何利用虚拟相机的三维注册技术解决虚拟场景与真实场景不处于同一空间的问题, 以使可视化仿真具有动态时效性; 如何通过视频监控获取的三维场景信息与虚拟物体叠加, 以解决传统可视化仿真中地形模型占用过多资源的问题, 并提高可视化仿真效率．结合西南某大型水利水电工程, 利用AR技术对该工程的施工进度仿真进行可视化展示．首先在无需建立地形模型的情况下实现了施工仿真和施工现场的紧密结合; 其次, 基于web service的数据查询和传输实现仿真成果的交互式动态三维场景查询, 同时通过基于硬件的增强现实方法以更少的资源消耗实现了更真实直观的可视化仿真, 为水利水电工程施工可视化仿真提供了新思路．
Abstract_English:At present，researches on visual simulation of construction schedule for core rock-fill dam are in majority virtual 3D visualization constructed by the construction simulation results. The terrain model is built according to the previous exploration data. By this method，rendering consumes more resources，the model is not easy to be modified and is quite different from the actual construction scene. To solve this problem，augmented reality(AR)technology was introduced into the construction simulation of water conservancy and hydropower projects in this paper and a visual simulation method for construction schedule of core rock-fill dam based on augmented reality was proposed. Two problems can be solved by this method: the problem that the virtual scene and the real scene are not in the same space has been solved using three dimensional registration technology of virtual camera in order to achieve the dynamic timeliness of visual simulation; the problem that the traditional terrain model takes too many resources has been solved by superimposing 3D scene information obtained by video surveillance with virtual objects and the efficiency of visual simulation has been improved. The AR technology was applied to visualize the construction progress of a large water conservancy and hydropower project in southwest China. Firstly，the construction simulation and construction site were closely integrated without the establishment of terrain model. Secondly，interactive dynamic 3D scene query of simulation results has been realized by using data query and transmission based on web service. Lastly，a more real and intuitive visual simulation has been achieved with less resource consumption by augmented reality method based on hardware. The study of this paper provides a new idea for visual simulation of water conservancy and hydropower project construction.
