数字沙盘与全息交互在江西省山洪灾害防治修水示范县中的应用
Application of Digital Sand Table and Holographic Interaction in Xiushui Demonstration County of Prevention and Control of Mountain Torrents in Jiangxi Province

本研究以修水县为设计场景和研究对象，将数字沙盘与全息交互技术相结合，建立了修水县山洪灾害防治数字沙盘，展示了丰富的基础信息和防汛专题信息，利用全息投影、场景融合等新技术，营造出信息融合的、交互式的三维视景模拟环境，实现了在MR中模拟演示灾难预警以及防御应急响应过程，让受众对象身临其境，防汛人员进一步了解到灾害防御工作内容和自身职责，普通群众体验到了山洪等自然灾害突发性和强大破坏力，有效提高了自身防灾减灾意识和灾害避险能力。
This study takes the county of Xiushui as both the design scene and research object. On one hand, digital sand table is combined with holographic interactive technology to build up the digital sand table for prevention and control of mountain flood disaster in the county of Xiushui. The digital sand table generates extensive basic information and flood prevention thematic information. On the other hand, new technologies like holographic projection and scene fusion are utilized to create an information fusion and interactive three-dimensional visual simulation environment. The sim-ulation demonstration in MR is created to show the disaster early warning and defense emergency response process. In this demonstration, the audience can enjoy an immersive experience. Flood control personnel can further understand the work content of disaster prevention and their own responsibilities. The general public can experience the sudden and powerful destructive force of natural disasters, such as mountain torrents. As a result of that, both of their awareness of disaster prevention and reduction and the ability of disaster avoidance can be effectively improved.
