METHOD FOR THE RECONSTRUCTION OF THE GEOMETRY OF THE INNER SURFACE OF A CAVITY

摘要

Structural cavities (1) location data in good form that this method is used to rebuild three-dimensional surface is that introducing probe (7) and optical sensor (8) enters cavity. Probe (7) is by the cavity (1) for the entrance being externally entering, so that the transformation for generating vision signal enters the surface (1) of the cavity of location data by computer apparatus. This method is preferably adapted to rebuild outer ear canal and data can be used for manufacturing the hearing devices of shell, such as hearing aid to control process units. Preferably, probe will be introduced before on application contraste point to the surface of chamber. Convert video signals, which are converted to location data, will preferably pass through iteration usage factor decomposition algorithm.
