Abstract:
1. An automatic resetting method using electronic means intended for a geometric model of a scene over a picture of the scene, the model and the picture of the scene being stored in the memory of an electronic device in the form of pixel matrices, the scene including fixed references with respect to the remainder of the scene, wherein the references can be detected within the matrices, the picture being taken by a camera arranged in a given zone with respect to the ground in a location of the zone and according to a shot angle determined relative to the scene, the method comprising: comparing, via the electronic means, the picture with the model having been adjusted in perspective by homography for superimposition of the references, wherein the electronic device calculates a fine homography function, H a first preliminary phase of determination of an average resetting homography including determining an average homography function, H a second, rough resetting phase including, after application of the average homography function H a third, fine resetting phase including, after application of the rough homography function H
