IMAGE CAPTURE ENVIRONMENT CALIBRATION METHOD AND INFORMATION PROCESSING APPARATUS
First Claim
1. A method of calibrating an image capture environment based on a captured image obtained by capturing an image of a physical space by an image capturing unit that captures the image of the physical space, the method comprising:
- an imaging step of capturing an image of the physical space using the image capturing unit;
a detecting step of detecting an index serving as a reference for calibration from the captured image of the physical space;
a calculating step of calculating a position and orientation of the image capturing unit from the index detected in the detecting step;
a presenting step of presenting a virtual three-dimensional object which designates the next target position and orientation of the image capturing unit required to acquire calibration information; and
a calibrating step of calibrating one of image capturing unit unique information, geometric information associated with the physical space, and a relationship between the image capturing unit and the physical space using the index detected in the detecting step.

Abstract
In a method of calibrating an image capture environment based on a captured image obtained by capturing an image of a physical space by an image capturing unit that captures the image of the physical space, an image of the physical space is captured using the image capturing unit, an index serving as a reference for calibration is detected from the captured image of the physical space, the position and orientation of the image capturing unit are calculated from the detected index, and image capturing unit unique information, geometric information associated with the physical space, or the relationship between the image capturing unit and the physical space is calibrated using the obtained data.
