Title (EN) METHOD AND APPARATUS FOR LOCATING OBJECTS USING UNIVERSAL ALIGNMENT TARGETS
(FR) PROCEDE ET APPAREIL PERMETTANT DE LOCALISER DES OBJETS AU MOYEN DE CIBLES D'ALIGNEMENT UNIVERSELLES
Abstract:
(EN) A method and apparatus for locating objects by means of machine vision alignment using cooperative targets. Novel cooperative targets are used that have substantial performance advantages. Alignment methods having non-translation alignment capabilities are used, such as geometric pattern matching, cooperating with suitable targets to perform alignment in non-translation degrees of freedom, such as orientation and size.
(FR) L'invention concerne un procédé et un appareil permettant de localiser des objets au moyen de l'alignement par vision artificielle faisant appel à des cibles coopératives. On utilise de nouvelles cibles coopératives qui présentent des avantages de performance sensibles. On utilise également des procédés d'alignement présentant des capacités d'alignement non translationnel, tels que l'appariement de motifs géométriques, lesquels procédés d'alignement coopèrent avec des cibles appropriées afin d'effectuer un alignement dans des degrés de liberté non translationnels, tels que l'orientation et la taille.
