Abstract
A monitoring system using two or more cameras to monitor a space in 3 dimensions is disclosed. One or more virtual 3-D monitored volumes relating to dangerous or restricted areas, are constructed, preferably as CSG objects, within this space. By detecting an object moving within the view of the cameras, the system can determine if a moving object intersects any monitored volumes and take appropriate action.
