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.

Dependent claims

A method for generating a full three-dimensional (3D) digital geometry for an ear, the method comprises the steps of:

(A) providing a personal computing (PC) device and at least one remote server, wherein a plurality of 3D digital ear impressions is stored on the remote server;
(B) retrieving a series of video frames of a target ear with the PC device;
(C) relaying the series of video frames from the PC device to the remote server;
(D) processing the series of video frames with the remote server in order to identify a plurality of ear landmarks for the target ear;
(E) executing a 3D reconstruction process with the remote server in order to generate a plurality of outer ear 3D data points from the ear landmarks;
(F) processing the outer ear 3D data points with the remote server in order to identify at least one tragus angle for the target ear;
(G) comparing the outer ear 3D data points to each 3D digital ear impression with the remote server in order to identify a matching impression from the plurality of 3D digital ear impressions;
(H) registering the outer ear 3D data points to the matching impression with the remote server in order to extrapolate a plurality of full ear geometry 3D data points;
(I) adjusting a plurality of canal 3D data points in accordance to the tragus angle with the remote server, wherein the full ear geometry 3D points includes the canal 3D data points;
and
(J) compiling the full ear geometry 3D points into a 3D reconstruction model of the target ear with the remote server.
