Abstract:
1. A method of calibrating an image capture environment based on a captured image obtained by an image capturing unit, the method comprising: a deciding step of deciding a target position and orientation of the image capturing unit to be used to calibrate the image capture environment by referring to a history of the target position and orientation of the image capturing unit used for calibration; a presenting step of presenting a virtual object which designates the target position and orientation of the image capturing unit decided in the deciding step; a determination step of determining whether a current position and orientation of the image capturing unit matches with the target position and orientation of the image capturing unit designated by the virtual object; a notification step of notifying a user that the current position and orientation of the image capturing unit is appropriate to calibrate the image capture environment if it is determined that the current position and orientation matches with the target position and orientation in the determination step; an obtaining step of an image of the physical space captured by the image capturing unit at the position and orientation which is determined to match with the target position and orientation; a detecting step of detecting an index from the captured image of the physical space; a calibrating step of calibrating the image capture environment of image capturing unit using the index detected in the detecting step as a reference for calibration; and an updating step of updating the history of the target position and orientation of the image capturing unit based on the target position and orientation decided in the deciding step.
