POSITION AND POSTURE DETECTION DEVICE, AR DISPLAY DEVICE, POSITION AND POSTURE DETECTION METHOD, AND AR DISPLAY METHOD

摘要

The purpose of the present invention is to detect with a simple configuration the position and posture of a user with high accuracy from a small amount of information. Provided is a position and posture detection device comprising: an image-capture unit 102 for image-capturing a predetermined image-capture range including two or more objects; an object detection unit 105 for specifying a pixel position of each of the objects in the image that is image-captured by the image-capture unit 102; an orientation calculation unit 106 for calculating an orientation of each of the objects with respect to the image-capture unit 102 by using the pixel position, map information on each of the objects, and a focal distance of the image-capture unit; and a position and posture calculation unit 107 for calculating the position and posture of the image-capture unit 102 by using the orientation of each of the objects and the map information. The object detection unit 105 extracts two-dimensional map information corresponding to the image-capture range from two-dimensional map information, in which information on positions and shapes of a plurality of objects within a predetermined region are stored, and specifies a pixel position by using the two-dimensional map information.
