ABSTRACT:
An apparatus for recording a shape of a section of the human ear is provided. The apparatus has a recording device for recording a spatial shape of a first and a second subsection of the section and for recording a position or a variable representing the position of the first and the second subsection relative to a predetermined optical feature of the section. The apparatus has an evaluation device for obtaining shape information about the section by combination of the shapes of the subsections based on the recorded positions or the variables representing the respective position. This enables a number of individual images to be joined together into a three-dimensional map based on natural features in the auditory canal, such as skin flecks or veins for example.
