Abstract

The present invention discloses a method and system for determining orientation of a capsule endoscope. An external magnetic field is provided outside the capsule endoscope, and an internal magnetic field is provided inside the capsule endoscope. Magnetic field data is obtained according to the external magnetic field and the internal magnetic field, and acceleration data of the capsule endoscope is obtained. When the polarization direction of the external magnetic field is horizontal, the orientation information of the capsule endoscope is obtained according to the acceleration data. When the polarization direction of the external magnetic field is non-horizontal, the orientation information of the capsule endoscope is obtained according to the acceleration data and the magnetic field data.
