Performance of novel algorithm of gross error detection and correction of water depth of single beam bathymeter
Liu L · Port & Waterway Engineering · 2014
The single beam bathymeter is an important equipment of underwater terrain surveying in the ocean and especially in the river. Even though the speed value of the sound is set correctly,the depth value may still be the gross error as result of other measurement factors. This article originally presents the concept of terrain chain and a novel algorithm of water depth gross error detection and correction based on the terrain chain concept. The performance of processing several water depth dataset collected by a single beam bathymeter in the Changjiang River shows the obvious effect on gross error detection and correction.
