| 1. An information processing method for an information processing apparatus including a calibration-information computing
section to calculate first arrangement information of first indices arranged on an object and second arrangement information
of a sensor arranged on the object, the information processing method comprising steps of:
obtaining a first image of the object captured by a capture device;
receiving orientation information of the object, the orientation information being measured by the sensor arranged on the
object;
detecting; the first indices arranged on the object, from the first image and
calculating, by the calibration-information computing section, the first arrangement information relative to the object and
the second arrangement information relative to the object, from the received orientation information and first image coordinates
of the detected first indices.
