Classification: CPC G  H | IPC G

Claim 9:
10. A calibration method of a calibration device, comprising the steps of:
detecting, in a field of view of a first imaging device, an image of a second imaging device, the first imaging device being an imaging device outputting field-of-view information including a bitmap image and a range image, and estimating a relative position and a relative attitude of the second imaging device with respect to the first imaging device solely based on a single detected image of the second device; and
calculating transformation information between a coordinate system of the first imaging device and a coordinate system of the second imaging device, based on the estimated relative position and relative attitude,, wherein the range image is an image in which range information is added to each pixel of the range image, and, wherein each of the imaging devices is an aerial imaging device without a stationary position, and, wherein each of the imaging devices is capable of measuring a distance between itself and a target and distance between the imaging devices is not known beforehand.
