Abstract
In this paper, a position tracking method based on a magnetic marker and hall sensors array, which could be used in capsule endoscope localization, is introduced. The experiment setup is shown, together with the minimization algorithm to analyze the data. It was demonstrated that the calculated position errors could be around 2mm when the marker is moving with a velocity of 2mm/s. Compared with other tracking system, this system cost much lower.
