Research on the Problem of Sea Area Survey Line in Multi Beam Sounding System
In order to conduct full coverage depth measurement of the actual sea area,it is necessary to solve the problem of measuring line distribution of the measuring vessel.A sea area routing model is established by studying the working principle of multi beam sounding system.The measurement line,multi beam area,and seabed slope of the measurement vessel are abstracted into spatial straight line equations and plane equa-tions.Under different conditions of seabed slope and measurement line directions,a calculation method for the position,measurement line direction,measurement line spacing,coverage width,and other related pa-rameters of the measurement vessel was obtained.Regional segmentation was performed on actual sea area data,and the submarine slope surface was fitted using the least square method.This wiring model can provide a measurement scheme that meets the convenience of measurement and data integrity,and has practical ap-plication for the research of marine survey line problems.
