Abstract (en)
[origin: EP0577491A1] The method makes it possible to monitor a three-dimensional scene and to detect anomalies. A three-dimensional, geometric reference model of the said scene is constituted associating, with each scene, corresponding points in the field of at least two sensors placed at a distance from one another and sensitive to a radiometric parameter (such as the brightness) of the scene. The real scene is periodically synthesized on the three-dimensional geometric model, on the basis of each of the representations thereof which are supplied by the sensors. On that basis, the synthesized scenes are compared to each other in order to reveal discrepancies due to a modification of the 3D model which are of a size greater than a defined value. <IMAGE>
