摘要
换能器和电罗经的安装误差以及GPS的导航延迟等因素往往造成多波束测深系统存在系统内部误差,参数校正是消除内部误差的有效方法。本文详细分析了各项校正参数的海试方案和计算模型,结合科学计算可视化技术给出了各项校正参数的可视化交互求解思路和模型,实现了校正参数的快速、直观求解。
The installation error of transducer and gyro-compass and the navigation delays of GPS often cause the internal error of multi-beam bathymetric system. Parameter correction is an effective way to eliminate internal error. Sea trial programs and computing models of all kinds of calibrating parameters were analyzed in details. A visualized interactive solution idea and models were proposed based on the scientific computing visualization technology, which implemented the fast and intuitive solution for correcting parameters.
