Abstract
A method of calibration for a head-mounted display device including an camera, an inertial sensor and a processor causes the processor to realize functions of: acquiring a first image and a second image that are captured by imaging a first real marker with the camera when the inertial sensor is respectively at a first pose and a second pose; acquiring a difference in pose between the first pose and the second pose based on output of the inertial sensor; and deriving a spatial relationship between the camera and the inertial sensor based at least on the first image, the second image and the difference in pose.
