Short summary
For wireless capsule endoscopy (WCE), precise localization is an open research topic. In this study, a novel differential magnetic localization method for WCE is proposed. The differential method prevents interference of the geomagnetic field. Therefore, the mean position and orientation errors were significantly reduced by three orders in magnitude to less than 0.1 mm and 0.1°, respectively. In the future, the simulation-based results will be validated in experiments.
