Title (EN) IMPROVED METHOD FOR GROUND PENETRATING RADAR DETECTIONS AND APPARATUS THEREOF
(FR) PROCÉDÉ AMÉLIORÉ POUR DÉTECTIONS RADAR PÉNÉTRANT DANS LE SOL ET APPAREIL ASSOCIÉ
Abstract:
(EN) A method for detecting the position of objects (10) under a surface (200) with respect to a reference Cartesian system S(x,y) having origin 0(0,0) and axes x and y, said method comprising the steps of prearranging a GPR apparatus (110), said GPR apparatus (110) comprising a GPR sensor, a distance detecting unit (115) configured to measure a distance with respect to a not transparent object, a control unit, a centre of reference C(xc,yc) having coordinates xc and yc on the reference Cartesian system S(x,y). The method comprises then the steps of prearranging a first linear wall (120), said first wall (120) having direction parallel to the axis x of the reference Cartesian system S(x,y), handling the apparatus (110) on the surface (200), detecting a first measurement of distance between the distance detecting unit and the first linear wall (120), processing said first measurement of distance by means of said control unit in order to calculate the coordinate yc of the centre of reference C(xc,yc), repeating the steps of detecting and processing said first measurement of distance in order to calculate a change of the coordinate yc during the step of handling, associating a coordinate yi = yci to an i-th object (10) detected, where yci is value of the coordinate yc at the detection by the GPR sensor of the i-th object (10).
(FR) La présente invention concerne un procédé de détection de la position d'objets (10) sous une surface (200) par rapport à un système cartésien de référence S(x,y) d'origine 0(0,0) et ayant des axes x et y, ledit procédé comprenant les étapes consistant à agencer au préalable un appareil GPR (110), ledit appareil GPR (110) comprenant un capteur GPR, une unité de détection de distance (115) configurée pour mesurer une distance par rapport à un objet non transparent, une unité de commande, un centre de référence C(xc,yc) ayant des coordonnées xc et yc sur le système cartésien de référence S(x,y). Le procédé comprend ensuite les étapes consistant à agencer au préalable une première paroi linéaire (120), ladite première paroi (120) ayant une direction parallèle à l'axe x du système cartésien de référence S(x,y), manipuler l'appareil (110) sur la surface (200), détecter une première mesure de distance entre l'unité de détection de distance et la première paroi linéaire (120), traiter ladite première mesure de distance au moyen de ladite unité de commande afin de calculer la coordonnée yc du centre de référence C(xc,yc), répéter les étapes de détection et de traitement de ladite première mesure de distance afin de calculer un changement de la coordonnée yc lors de l'étape de manipulation, associer une coordonnée yi = yci à un i-ième objet (10) détecté, où uci est la valeur de la coordonnée yc au niveau de a détection par le capteur GPR du i-ième objet (10).
