Abstract (en)
The monitored region (S) is monitored by image signal generating means such as video cameras (2) in order to obtain a succession of images of the bodies (A, B) present in the monitored region, each image corresponding to a defined instant. The images are processed in such a way as to obtain, for each instant considered, a volumetric map of each body present in the region (S). This map, which identifies characteristics of shape, position, volume and dimensions of the body to which it refers, is processed in order to extract from it at least one parameter selected from the following group: descriptors of shape and volume, such as the volumetric map itself, the co-ordinates of position and the dimensions of each body to which the volumetric map refers. The parameter or a succession of values of the parameter obtained in this way is then compared with at least one model of these characteristics stored in a processing unit (1). Depending on the outcome of this comparison operation, a procedure of surveillance and/or reporting may be selectively activated. The solution is applicable, for example, to the automatic monitoring of museum environments, e.g. to ensure that visitors do not come too close to an exhibited work, or to the monitoring of industrial environments, e.g. to ensure that an operator does not come too close to a dangerous machine or process. <IMAGE>
