Magnetic tracking systems have been increasing in popularity due to their lower expense and small size of their tracked objects, but they are sensitive to ferromagnetic objects within their work volumes. Optical tracking systems can overcome this disadvantage, however there are some occlusions problem in optical system. Hence, we present a novel hybrid localization system combining optical one and...
To track the movement of a wireless capsule and get the 6D localization and orientation information of the capsule, a magnetic localization and orientation system is designed. In this system, we propose to enclose two orthogonal permanent magnets in the capsule. With the magnetic sensor array arranged out of the human body, we can measure the magnets' magnetic signals, and compute the magnets' 3D...
To build a new type of wireless capsule endoscope with interactive gastrointestinal tract examination, a localization and orientation system is needed for tracking 3D location and 3D orientation of the capsule movement. The magnetic localization and orientation method produces only 5 DOF, but misses the information of rotation angle along capsule's main axis. In this paper, we presented a complementary...
