Target Tracking on Sensing Surface with Electrical Impedance Tomography

Abstract

Electrical impedance tomography (EIT) has been successfully applied to several important application domains such as medicine, geophysics and industrial imaging. EIT offers a high temporal resolution, which allows to track the location of a moving target on a conductive surface accurately. Existing EIT methods are geared towards high image quality instead of smooth target trajectories, which makes them suboptimal for target tracking. We combine EIT methods with hidden Markov models for tracking moving targets on a conductive surface. Numerical experiments indicate that the proposed method outperforms existing EIT methods in target tracking accuracy.
