Measuring geometry of underwater body, e.g. sea bed, by calibrating with measuring body with known geometry introduced to measuring location

摘要

A body (4) with a known geometry is introduced to the measuring location, either into or on top of the underwater body (2), and the geometry of this body is recorded during the measurement of the underwater body contours. An Independent claim is also included for the measuring body, comprising a frame construction (5) with at least three legs (6) for resting on.
