Information processing apparatus, mixed reality presentation apparatus, method thereof, and storage medium
First Claim
1. An information processing apparatus that derives the calibration information needed to measure the position and/or attitude of a measuring object based on the output values of a position and/or attitude sensor, comprising:
- input means for entering information about a match between the position and/or attitude of said measuring object and a predetermined position and/or attitude;
acquisition means for acquiring the output values from said position and/or attitude sensor according to the input by said input means; and
operation means for deriving said calibration information, based on said predetermined position and/or attitude and the output values of said position and/or attitude sensor acquired by said acquisition means.

Abstract
A view transformation matrix that represents the position/attitude of an HMD is generated based on a signal that represents the position/attitude of the HMD (S602). On the other hand, landmarks and their locations are detected based on a captured picture (S604) and a calibration matrix ΔMc is generated using the detected locations of the landmarks (S605). The position/attitude of the HMD is calibrated using the view transformation matrix and calibration matrix ΔMc generated by the above processes (S606), a picture of a virtual object is generated based on external parameters that represent the position/attitude of the calibrated HMD, and a mixed reality picture is generated (S607). The generated mixed reality picture is displayed in the display section (S609).

21. An information processing method that derives the calibration information needed to measure the position and/or attitude of a measuring object based on the output values of a position and/or attitude sensor that detects the position and/or attitude of said measuring object, comprising:
-
an input process of entering information about a match between the position and/or attitude of said measuring object and a predetermined position and/or attitude;
an acquisition process of acquiring the output values from said position and/or attitude sensor according to the input in said input process; and
an operation process of deriving said calibration information, based on said predetermined position and/or attitude and the output values of said position and/or attitude sensor acquired in said acquisition process. - View Dependent Claims (22, 23, 24)
