多种智能测量设备在水库水下地形测量中的联合应用

Joint Application of Multiple Intelligent Measurement Equipment inReservoir Underwater Topography Measurement

浅水区和沼泽区是水库水下地形测量的难点,大船由于吃水深无法到达,人员进入也相当困难。针对这些区域目前一种方法是利用机载激光测深系统进行测量,缺点是成本太高,不具有普遍性;另一种方法是采用插值法,缺点是精度低、无法满足大比例尺测量精度。为解决此问题,本项目研究了利用多波束测深系统深水区测量、应用无人测量船进行浅水区测量、多旋翼无人机进行沼泽区测量相结合的方式,实现了全覆盖、无盲区大比例尺水下地形测量,数据精度可靠,可满足IHO国际标准要求,解决了浅水区和沼泽区测量难、精度差的难题。

shallow water area and marsh area are the difficulties of underwater topographic survey of reservoir.The current approach to these areas is to use the airborne laser sounding system for measurement.The other method is interpolation,which has the disadvantage of low accuracy and cannot meet the large-scale measurement accuracy.To solve this problem,the project was studied using multi-beam sounding system in deep water to shallow water area measurement,the application of unmanned surveillance,multiple UAV rotorcraft swamp area measurement technology of combining way,realizing a complete coverage of the,no blind area large scale underwater topographic survey,data accuracy and reliable,satisfies the requirement of international standard IHO,solve the shallow water area and marsh area measurement difficult,difficult problems of poor precision.
