Abstract
The three-dimensional structure of the surface of a cavity is reconstructed. The cavity can be the outer ear canal of a person. A probe with an optical sensor is introduced into the cavity to produce video signals, which are transmitted to a computer device. The computer device transforms the video signals into position data representing the surface of the cavity, thereby defining the three-dimensional structure of the cavity.
