METHOD AND SYSTEM FOR RECONSTRUCTING THE THREE-DIMENSIONAL SHAPE OF THE SURFACE OF AT LEAST A PORTION OF AN EAR CANAL AND/OR OF A CONCHA
摘要
The method for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha comprises - for each of a multitude of points (12) on said surface (14) - the step of using a chromatic coded distance measurement technique for determining a distance value (40) representative of a distance to said point (12) ; and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (40) . The system for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha, comprises a distance measurement unit for determining - by means of a chromatic coded distance measurement technique and for each of a multitude of points (12) on said surface (14) - a distance value (40) representative of a distance to said point; and a reconstructing unit (50) operationally connected to said distance measurement unit for reconstructing said three- dimensional shape based on said multitude of distance values (40).
