| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we focus on tracking moving objects in a building using a binary-sensor network. In buildings, there are multiple points where objects temporarily change their velocities, such as doors and stairs. We call these points as gates. We assume that the velocity of an object does not almost change before and after passing a gate. We first divide the entire area in a building into multiple sub-regions each of which has gates as their entrances. To track objects in a sub-region, we apply the conventional method based on a Bayesian estimation. The conventional method conducts object tracking using statistically obtained information on object velocities. We expect that we can improve accuracy of object tracking by proposing a method to share the velocity information among sub-regions. Through simulation experiments, we demonstrate that the accuracy of object tracking has a maximum of 35~\% improvements compared with the conventional method. |
