Automatic data processing method based on multi-beam sounding system

Abstract

The invention relates to the technical field of seabed terrain observation, in particular to an automatic data processing method based on a multi-beam sounding system, wherein the data automatic dataprocessing method comprises the following steps of 1 data collection and original data analysis, wherein data collection is carried out by a measuring system designed in the method, and the original measurement data are decoded; 2, coordinate conversion, wherein the attitude information obtained through an attitude instrument is used for correcting the sounding data obtained under a carrier coordinate system G system to obtain the position of a sounding point in a geographic coordinate system P system; and 3, abnormal data detection and removal, wherein the abnormal data are automatically identified and removed according to the algorithm designed in the method. According to the method, the efficiency of abnormal data detection and removal is improved, the operation process is simplified, the operation cost is lowered, and the reliability of multi-beam sounding data is improved.

Description

technical field [0001] The invention relates to the technical field of seabed topography observation, in particular to a data automatic processing method based on a multi-beam bathymetric system. Background technique [0002] The concept of seafloor topography is inherited and developed from bathymetry. At the beginning of the 20th century, people invented the application of echo sounding to ocean sounding. In the 1970s, a multi-beam bathymetry system appeared, which can give the depth values ​​of hundreds or even thousands of measuring points in a plane perpendicular to the route at one time, and can accurately and quickly measure the depth within a certain width underwater. The shape and coordinates of the target, so as to more reliably describe the state of the underwater landform. Due to the complexity of the marine environment, the bathymetric data collected by the multi-beam sonar survey system will inevitably have some systematic errors and abnormal data. Therefore...

Problems solved by technology

The manual method is highly subjective and inefficient. Most of the traditional data processing software is based on a single survey line, which cannot meet the editing requirements of a large number of multi-beam bathymetric data.
