Abstract:
A method for detecting intrusions in a monitored volume in which:
- N tridimensional sensors acquire local point clouds (C) in respective local coordinate systems (S),
- a central processing unit (3) receives the acquired local point clouds (C) and, for each sensor (2), computes updated tridimensional position and orientation of the sensor (2) in a global coordinate system (G)of the monitored volume by aligning a local point cloud (C) acquired by said tridimensional sensor with a global tridimensional map (M) of the monitored volume (V), and
generates an aligned local point cloud (A) on the basis of the updated tridimensional position and orientation of the sensor (2),
- the central processing unit monitors an intrusion in the monitored volume (V) by comparing a free space of the aligned local point cloud (C) with a free space of the global tridimensional map (M).
