UNDERWATER MAGNETIC FIELD MAPPING SYSTEM AND METHOD USING AUTONOMOUS SURFACE VEHICLE

摘要

The present invention relates to an underwater magnetic field mapping system and method using an autonomous watercraft, in particular, position information obtained from each of a GPS receiver, magnetometer, and attitude sensor mounted on the autonomous watercraft, 3D magnetic field vector and attitude information [Roll] , Pitch and Yaw] are transmitted to the land control room side, and the magnetic force value correction unit obtains a 3D correction value using the 3D magnetic field vector using the posture information and refers to the 3D correction value from the fixed coordinate system. Converted to a coordinate system, represented by F (total intensity), D (declination), and I (inclination), which are geomagnetic expression methods, and mapped F, D, and I to location information, and then interpolated unexplored areas using regression to obtain a high-resolution underwater magnetic field. An underwater magnetic field mapping system and method using an autonomous watercraft capable of obtaining a map.
