Abstract

There is provided a method for tracking an object within a 3D scene captured by a plurality of image sensors. The object's 3D position in relation to the scene is inferred from information acquired from one or more images captured by the plurality of image sensors. Each image sensor is associated with a floor plane equation, and the object is tracked in relation to the floor plane defined by the floor plan equation.
