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.
