Abstract

La présente invention se rapporte aux techniques de mesures et peut être utilisée dans des systèmes d'identification d'objets à vocations diverses. On choisit tout d'abord le pas de déplacement du capteur de numérisation en fonction des dimensions minimales des éléments composant l'objet et qu'il est nécessaire de fixer, et en fonction du temps de balayage ainsi que des exigences de qualité du balayage, entre autres. Le processus de balayage commence d'un point (3) choisi au hasard sur l'objet (2). On définit ensuite, dans la zone (4) entourant ce point (3) (par exemple, un cercle), le sens de déplacement (1) du capteur de numérisation qui va correspondre à une direction vers un point situé sur la périphérie de la zone entourant l'objet, ceci de manière à obtenir un changement maximal du paramètre de balayage par rapport à sa valeur au niveau du point (3). On procède ensuite au déplacement rectiligne du capteur de numérisation depuis le point (3) et selon la direction choisie en fonction d'un pas donné (t). A la fin de chaque pas, la valeur du paramètre de balayage est mesurée et comparée avec la valeur au niveau du point (3). Si la différence entre ces valeurs ne dépasse pas une grandeur prédéterminée, le capteur est déplacé d'un autre pas dans une direction voulue. Si la différence entre les valeurs du paramètre dépasse une grandeur donnée, le déplacement du capteur de numérisation dans une direction donnée est interrompu et la direction de balayage redéfinie. Le balayage est interrompu lorsque le volume d'informations sur l'objet balayé s'avère insuffisant pour permettre son identification.
