Abstract:
Localization system was designed based on analytic equation of permanent magnetic field to localize the swallowing electrical capsule in the gastrointestinal. Algorithm was presented and experiment was made. Two three-axis magnetism sensors were mounted in the capsule. The non linear equations set of sensor's output and capsule's position and attitude was created according to space position and attitude relationship model. The equations set was resolved with numerical method. Comparison between the calculation value and expected value showed that this method was feasible.
