Composite marker and composite marker information acquisition apparatus
First Claim
1. A composite marker including an optical marker section having at least three feature points obtained by one of symbol and design containing a character which can optically be distinguished, the 3D arrangement of the feature points being known, comprising:
- a storage section configured to store location information of the optical marker section by which the area where the optical marker section is located can be specified; and
a transmission section configured to transmit the location information of the optical marker section stored in the storage section in a non-contacting manner, the optical marker section, storage section, and transmission section being formed integrally.

Abstract
A composite marker includes an optical marker section having at least three feature points obtained by one of symbol and design containing a character which can optically be distinguished, the 3D arrangement of the feature points being known. The composite marker further includes a storage section configured to store location information of the optical marker section by which the area where the optical marker section is located can be specified, and a transmission section configured to transmit the location information of the optical marker section stored in the storage section in a non-contacting manner. The optical marker section, storage section, and transmission section are formed integrally.

15. A composite marker which is targeted by an information acquisition apparatus including a camera having a predetermined capturing area, and a non-contact ID information acquisition section which acquires information retained by a non-contact ID tag set in a predetermined position relative to the capturing area, the composite marker comprising:
-
an optical maker section having at least three feature points obtained by one of symbol and design containing a character which can optically be distinguished, the 3D arrangement of the feature points being known, and the position and posture of which relative to the camera that captures an image including the feature points thereof can be specified based on the captured image; and
a non-contact ID tag including a storage section configured to retain information related to one of the optical marker section and an article to which the optical marker section is fixed and a transmission section configured to transmit information retained by the storage section in a non-contacting manner, the transmission section including an antenna section fixed to a predetermined position relative to the optical marker section. - View Dependent Claims (16, 17, 18, 19)

20. A composite marker information acquisition apparatus comprising:
-
an image capture section having a predetermined capturing area and configured to capture a marker which has an optical feature and which is fixed to an object located within the capturing area;
an information acquisition section configured to acquire information related to one of the marker and object fixed to the marker from a non-contact ID tag whose position is fixed relative to the marker and which retains the information related to one of the marker and object; and
an information acquisition control section configured to allow the information acquisition section to perform information acquisition based on an image captured by the image capture section. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
