The invention relates to a method for detecting an object (1) in relation to a surface (2). A synthetic image (3c, 4c) is produced from at least two distinct viewpoints (3, 4), for each of said viewpoints, by means of a geometrical transformation comprising at least one perspective projection (3a, 4a) of the object on the surface (2), each synthetic image being associated with the viewpoint concerned. By discriminating between the synthetic images, it is possible to detect the presence of and determine the position of the object (1) in relation to the surface (2), by searching for contrast inversions. The invention can be used for surveying a swimming pool.
La présente invention concerne un procédé pour détecter un objet (1) par rapport à une surface (2). On réalise par une transformation géométrique comprenant au moins une projection en perspective (3a, 4a) dudit objet sur ladite surface (2) à partir d'au moins deux points de vue distincts (3, 4) et pour chacun d'entre eux une image de synthèse (3c, 4c) associée au point de vue considéré. On discrimine entre les images de synthèse pour détecter la présence et déterminer la position dudit objet (1) par rapport à ladite surface (2), en recherchant des inversions de contraste. L'invention s'applique à la surveillance d'une piscine.
