Abstract
A device and a processing method for offsetting an attitude error of a semi-airborne electromagnetic system. The method includes following steps: adjusting attitude angles of the adjustable offset coil based on the changing attitude angle of the measuring coil; obtaining a magnetic induction intensity of offset coils based on the offset coil pairs after an attitude angle adjustment; performing a calculation based on the magnetic induction intensity of the offset coils to obtain attitude error data of the measuring coil; obtaining a magnetic induction intensity of the measuring coil with an attitude error offset based on the magnetic induction intensity and the attitude error data of the measuring coil.
