摘要：
A device for scanning a body orifice or surface including a light source and a wide angle lens. The light from the light source is projected in a pattern distal or adjacent to the wide angle lens. Preferably, the pattern is within a focal surface of the wide angle lens. The pattern intersects a surface of the body orifice, such as an ear canal, and defines a partial lateral portion of the pattern extending along the surface. A processor is configured to receive an image of the lateral portion from the wide angle lens and determine a position of the lateral portion in a coordinate system using a known focal surface of the wide angle lens. Multiple lateral portions are reconstructed by the processor to build a three-dimensional shape. This three- dimensional shape may be used for purposes such as diagnostic, navigation, or custom-fitting of medical devices, such as hearing aids.
