Abstract
The position of the same point on each of the images of a single object formed by the imaging means of an endoscope is detected, and shift maps between the respective images are formed using the detected positions. Each of the imaging positions of the imaging means is estimated from the shift maps, and a relative shape of the object is then estimated from the imaging positions. Since a relative shape of the object is estimated using the correlation between the respective images, a relative shape of the object can be estimated even when not only the imaging means but also the object are moved. An absolute shape of the object can also be estimated using a length as a reference value.
