APPARATUS AND METHOD FOR DETECTING POSITION AND ORIENTATION OF MOBILE OBJECT
First Claim
1. An apparatus for detecting a position and orientation of a mobile object, comprising:
- a relative position detection unit for acquiring a relative position with respect to movement of the mobile object;
an absolute position detection unit for acquiring an absolute position of the mobile object;
a position updating unit for updating the position and orientation of the mobile object based on an initial or previous position of the mobile object and the relative position; and
a position correction unit for updating a current position of the mobile object with the absolute position, and correcting the orientation of the mobile object by setting the moving direction of the mobile object in the relative position equal to the moving direction of the mobile object in the absolute position.

Abstract
An apparatus for detecting a position and orientation of a mobile object includes: a relative position detection unit for acquiring a relative position with respect to movement of the mobile object; an absolute position detection unit for acquiring an absolute position of the mobile object; and a position updating unit for updating the position and orientation of the mobile object based on an initial or previous position of the mobile object and the relative position. The apparatus further includes: a position correction unit for updating a current position of the mobile object with the absolute position, and correcting the orientation of the mobile object by setting an orientation of the mobile object in the relative position equal to an orientation of the mobile object in the absolute position.
