【摘要】 以水下地形地貌测量为例,通过测量仪器硬件有效安装和倾斜改正,对信标GPS定位信号与换能器测深水声信号的空间位置在垂直轴上进行统一;以计算机API时钟作为时间基准,使定位信息和测深信息在时间轴上对齐;经过位置与时间信息融合后,形成空间匹配的三维数据。更多还原

【Abstract】 Taking underwater topographical surveying as an example,the position and depth are consolidated in the space by fixing instruments and adjusting slant;the API clock of computer acts as the basis to right of the information orientation and the depth in the time axis.Then two types of information are formed into right three-dimension datas of space.更多还原
