Abstract
A template creation device includes an acquisition unit configured to acquire a plurality of templates from a plurality of images of different poses of a single object, or a plurality of images for a plurality of objects; a clustering unit configured to divide the plurality of templates into a plurality of groups on the basis of a similarity score; and an integration unit configured to combine the templates in a group into an integrated template, and to create a new template set from the plurality of integrated templates corresponding to each group in the plurality of groups.
Claims15
A template creation device configured to create a set of templates used in an object recognition device configured to recognize objects using template matching, the template creation device comprising:
- an acquisition unit configured to acquire a plurality of templates from a plurality of images of different poses of a single object, or a plurality of images for a plurality of objects;
- a clustering unit configured to run a clustering process which computes a similarity score for an image feature for a combination of two templates selected from the plurality of templates and divides the plurality of templates into a plurality of groups on the basis of the similarity score;
- and
- an integration unit configured to carry out an integration process which, for each of the plurality of groups, combines all the templates in a group into a single integrated template or a number of integrated templates less than the number of templates within the group, and to create a new template set from the plurality of integrated templates corresponding to each group in the plurality of groups.
A template creation method of creating a set of templates used in an object recognition device configured to recognize objects using template matching, the template creation method comprising:
- acquiring a plurality of templates from a plurality of images of different poses of a single object, or a plurality of images for a plurality of objects;
- computing a similarity score for an image feature for a combination of two templates selected from the plurality of templates and dividing the plurality of templates into a plurality of groups on the basis of the similarity score as a clustering process;
- and
- for each of the plurality of groups, combining all the templates in a group into a single integrated template or a number of integrated templates less than the number of templates within the group, and creating a new template set from the plurality of integrated templates for each group in the plurality of groups as an integration process;
- wherein
- a computer stores the plurality of integrated templates obtained by way of the integration process as a template set used for determining to which of the plurality of groups an object belongs.
