多源水深数据获取技术在深圳河地形测量中的应用

Application of multi-source water depth data acquisition technology in topographic measurement of the Shenzhen River

及时掌握作为深圳与香港地区界河的深圳河河道淤积变化情况,积累相关基础资料,对河道运行管理至关重要。依托深圳河地形测量项目,以获取深圳河河道地形、地貌数据为目的,在分析了传统测绘手段在潮汐河道测绘中的不足的基础上,结合测绘前沿的三维激光扫描、无人船测量、倾斜摄影测量等技术对深圳河河道进行全覆盖测量。多种前沿测绘技术方法的协同应用极大地提高了作业效率,有效地保障了成果精度和获取数据的完整性,为后续成果出图奠定了基础。多源水深数据获取技术可在同类型潮汐河道案例中应用,具有示范性效益。

Timely understanding of sedimentation changes in the Shenzhen River,the boundary river between Shenzhen and Hong Kong,is crucial for accumulating relevant foundational data and for the effective operation and management of the river.Relying on the Shenzhen River Topographic measurement project with the aim of acquiring topographic and geomorphic data of the Shenzhen River,and based on the analysis of the shortcomings of traditional surveying methods in tidal river mapping,the project employed cutting-edge technologies such as three-dimensional laser scanning,unmanned boat measurement,oblique photogrammetry,etc.,to conduct comprehensive measurements of the Shenzhen River channel.The synergistic application of various cutting-edge surveying techniques had greatly improved operational efficiency,effectively ensuring the accuracy of results and the integrity of data acquisition,laying the foundation for subsequent result mapping.The multi-source water depth data acquisition technology could be applied in similar tidal river cases,demonstrating significant benefits.
