Abstract
(EN)
Provided is a marker generation device which has a singular feature selection means and a marker pattern generation means. The singular feature selection means extracts feature points from an image, indicates the feature points in a predetermined space, and selects, as singular features, a plurality of parts where the number of feature points is equal to or less than a predetermined number in the space. The marker pattern generation means generates a plurality of kinds of marker patterns with the use of the whole or a part of the plurality of singular features.

La présente invention concerne un dispositif de création de marqueur qui comporte des moyens de sélection de caractéristiques singulières et des moyens de création de motifs de marqueur. Les moyens de sélection de caractéristiques singulières extraient des points caractéristiques d'une image, indiquent les points caractéristiques dans un espace prédéterminé, et choisissent, en tant que caractéristiques singulières, une pluralité de parties dans lesquelles le nombre de points caractéristiques est inférieur ou égal à un nombre prédéterminé dans l'espace. Les moyens de création de motifs de marqueur créent une pluralité de types de motifs de marqueur en utilisant l'ensemble ou une partie de la pluralité de caractéristiques singulières.
