<p>The present invention relates to a method for surveillance of a geographical area, in which a virtual 3D model of the area is used, and a system using the method. Images from surveillance cameras (1 , 2, 3) in the area are visualised (11, 21, 3') by being projected on the 3D model, and data from other types of fixed and/or mobile sensors (8, 9, 10, 11) is also visualised (5, 6, 7) in the 3D model.</p> |
