Image pick-up method and image pick-up system

An image pick-up system for picking up an image of an object, comprising:

• a camera unit having a structure in which a camera for picking up an image of an object, is mounted via a pan head on a moving pedestal;
• an operation means for calculating a positional relationship between the camera and the object;
• a setting means for setting a reference position on a floor surface on which the moving pedestal moves, and a reference angle of the moving pedestal to said operation means;
• and
• a detection means for detecting a moving amount of the moving pedestal from the reference position, and a rotation angle thereof from the reference angle;
• wherein said operation means calculates out a position and an angle of the camera with respect to the object on the basis of the reference position, the reference angle, the moving amount and the rotation angle of the moving pedestal, and transmits data of the position and the angle of the camera with respect to the object, to a computer for creating an image containing a real object image of the object taken with the camera.

An image pick-up system for picking up an image of an object, comprising:

• a moving pedestal including three wheels;
• camera unit having a structure in which a camera for picking up an image of an object, is mounted via a pan head on said moving pedestal;
• an operation means for calculating a positional relationship between the camera and the object;
• three encoders provided respectively for said three wheels of said moving pedestal;
• a plurality of sensors provided on said moving pedestal, for detecting a predetermined mark made on a floor surface on which said moving pedestal moves;
• and
• a setting means for setting a reference position on the floor surface, and a reference angle of said moving pedestal, which are found from detection values of said plurality of sensors and a pulse numbers counted by said encoders in the movement of said moving pedestal, to said operation means;
• wherein said operation means calculates out a position and an angle of the camera with respect to the object on the basis of the reference position, the reference angle, the moving amount and the rotation angle of said moving pedestal, which are obtained from the pulse numbers counted by said encoders, and transmits data of the position and the angle of the camera with respect to the object, to a computer for creating an image containing a real object image of the object taken with the camera.
