Information processing apparatus, information processing method, and information processing program

An information processing method comprising:

• by a computer,
• acquiring, from an inertial sensor attached to a moving body, inertial information associated with a movement of the moving body;
• acquiring first image information obtained by imaging the moving body from a first camera;
• and
• calculating third posture information on a basis of first posture information of the moving body obtained on a basis of the inertial information and second posture information of the moving body obtained on a basis of the first image information.

An information processing program for causing a computer to function as an information processing apparatus including:

• a first acquisition unit configured to acquire, from an inertial sensor attached to a moving body, inertial information associated with a movement of the moving body;
• a second acquisition unit configured to acquire first image information obtained by imaging the moving body from a first camera;
• and
• a calculation unit configured to calculate third posture information on a basis of first posture information of the moving body obtained on a basis of the inertial information acquired by the first acquisition unit and second posture information of the moving body obtained on a basis of the first image information acquired by the second acquisition unit.
