Abstract
A system and method for generating a full three-dimensional (3D) digital geometry for an ear provides a 3D reconstruction model that not only includes the outer area of an ear, but also the inner canal area up to the second bend. The system includes at least one remote server and a PC device. The remote server manages and processes data needed for the 3D model for an ear. The PC device allows a user to access the system and method. The remote server processes a series of video frames to generate outer ear 3D data points. Full ear geometry 3D data points are generated by comparing the outer ear 3D data points with a plurality of ear impressions. Canal 3D data points are then adjusted with a tragus angle for accuracy. The 3D reconstruction model that includes the outer ear area and inner canal area is finally generated.
