Abstract
A three-dimensional computer graphics model which represents a measurable range of a position and orientation sensor is prepared in advance. A composite image is generated by superimposing an image of a virtual object which represents the measurable range of the position and orientation sensor on an actually-sensed image in real space where the position and orientation sensor is placed. The composite image, when displayed, makes it possible to visually recognize the measurable range of the position and orientation sensor.

An image compositing method for superimposing a computer graphics image on an actually-sensed image, comprising:
- a setting step of setting a three-dimensional computer graphics model which represents a measurable range of a position and orientation sensor;
- a sensor position information acquisition step of acquiring position information about the position and orientation sensor;
- a CG image generating step of generating a computer graphics image which represents the measurable range using the position information about the position and orientation sensor and the three-dimensional computer graphics model;
- and
- an image compositing step of compositing the actually-sensed image with the computer graphics image.
An image compositing method for superimposing a computer graphics image on an actually-sensed image using position and orientation information measured by a position and orientation sensor with a predetermined measurable range, comprising:
- a setting step of setting a three-dimensional computer graphics model which represents the predetermined measurable range;
- a camera position and orientation information acquisition step of acquiring position and orientation information about a camera which shoots the actually-sensed image, using the position and orientation sensor;
