摘    要:随着海岛开发利用和基础设施建设的频繁,高效、精准地获取海岛形态基础数据就显得尤为迫切。三维地形地貌探测和构建技术的日臻完善,及时解决了海岛基础勘测时间长、效率低、精度小的问题。文章通过三维激光扫描和无人机航测手段,全覆盖扫描广西小庙墩(炮台口)海岛表面形态,结合RTK-DGPS实测验证和近景摄影测量,获取海岛实景,运用Geomagic Studio和Smart3D等软件,构建典型海岛三维数字高程模型(DEM),融合多源数据和海岛实景,还原海岛高精度仿真三维形态。为高精度勘测海岛提供有效手段,为海岛基础地理信息获取、地质灾害识别和生态环境修复提供基础数据支撑。

关 键 词:海岛  多源数据  三维形貌  融合  情景识别

Abstract:With the development and utilization of islands and the frequent construction of infrastructure,it is particularly urgent to obtain the basic data of island form efficiently and accurately.The improvement of the three dimensional topographical feature detection and construction technology has solved the problem of long island exploration time,low efficiency and low precision.In this paper,through the three dimensional laser scanning and unmanned aerial vehicle aerial survey,the full coverage of the surface pattern of the small temple pier in Guangxi,combined with RTK DGPS measurement verification and close range photogrammetry,to obtain the island real scene,using software such as Geomagic Studio and Smart3D,construct a typical island three dimensional digital elevation model,combine multi source data and island real scene,and restore the high precision simulation three dimensional shape of the island.It provided an effective means for high precision survey of islands,and provided basic data support for island based geographic information acquisition,identification of geological disasters and restoration of ecological environment.
Keywords:Island  Multivariate data  3D geomorphology  Fusion  Scene recognition
