Human tracking using ceiling pyroelectric infrared sensors

This paper presents a novel human tracking scheme by using pyroelectric infrared sensors. The scheme includes the visibility modulation of each sensor detector, the layout of the system, the localization and tracking algorithms. The results from the 3D simulations using Webots and Matlab together validate our scheme, and comparisons with other related schemes are made as well. Simulations show that the proposed approach achieves higher tracking accuracy than those of other schemes.
