Description

[0001] The present invention relates to a 3D facial skin diagnosis apparatus,

The present invention relates to a 3D facial skin diagnosis apparatus, and more particularly, it relates to a 3D facial skin diagnostic apparatus that processes each part of a face, processes skin images individually, or synthesizes a plurality of photographs, To a 3D facial skin diagnostic apparatus that is capable of acquiring and analyzing a stereoscopic image in a state where the 3D facial skin image is maximally blocked.

As the standard of living improves, there are more and more people who want to diagnose and improve their skin condition along with their interest in health. In the past, it was common to check with a doctor's eye including a magnifying glass .

Here, when a small-sized camera is diagnosed, the image of the skin is displayed on the monitor next to the camera, thereby enabling the doctor and the patient to visually recognize the condition of the skin and to treat the skin accordingly. It has become widespread and is still in use today.

However, now, by using a digital camera, it is possible to more precisely diagnose by using an algorithm that professionally processes the captured image after the image is taken, and it is possible to easily confirm the curing of the treatment. Is used to capture the frontal, left and right sides of a face using a digital camera, and analyze each skin image using an image processing algorithm.

In addition, the facial 3D product has been produced more and more by the modeling of the face by modeling several faces. In the active face sensing method such as structural light or laser, Data can be generated, but it is expensive and requires processing time through scanning.

In addition, the manual method based on the stereo method has a disadvantage in that it is relatively inexpensive, but has a disadvantage in that the resolution is low and the synthesis takes a long time. In order to achieve accurate matching, there is a disadvantage that a calibration procedure for estimating the camera internal property and position and direction is required.

Professor Vetter of the University of Basel, Switzerland, has succeeded in restoring high-quality face shapes using statistical facial models or just a few photographs. Many subsequent studies have implemented face compositing based on this model, It is not suitable for skin analysis system which requires real synthesis because it tends to be deformed into symmetrical and standardized face because it uses statistics.

In a typical stereo camera system configuration, images acquired at different points in time at the same time are processed, and images obtained by rotating the human face mechanically have variations in facial expressions and irregularities of illumination. Therefore, It is necessary to develop reliable 3D facial synthesis technology and skin diagnosis program algorithm that can be solved.
