The view of an observation station is limited and background objects may occlude a target object in cluttered scenes. Therefore a group of observation stations should cooperate with each other to keep tracking the target object in a wide spread area.
We have implemented the above appearance based object detection and
tracking method in four observation stations with APS cameras, and are
designing communication protocols for cooperative tracking of a single
object. Fig. 16 illustrates a basic processing scheme
in each observation station, where a cycle of event detection
state transition action
event detection is repeated. Note that in this
model, the action sets up a focusing region to guide the perception,
controls the camera action, and/or submits a message depending on the
current state. An event is detected through the perception and/or the
message acception, by which the state is changed.
