Description

얼굴 피부 진단기기 및 이를 이용하는 얼굴 피부 진단 방법Facial skin diagnosis device and facial skin diagnosis method using the same
본 발명은 얼굴 피부 진단기기에 관한 것으로서, 더욱 상세하게는 서로 다른 파장의 빛을 얼굴에 조사한 후 카메라로 촬영하고 3차원(3D) 이미지로 형성하는 얼굴 피부 진단기기 및 이를 이용하는 얼굴 피부 진단 방법에 관한 것이다.The present invention relates to a device for diagnosing facial skin, and more particularly, to a device for diagnosing facial skin that irradiates a face with light of different wavelengths, photographing it with a camera, and forming a three-dimensional (3D) image, and a method for diagnosing facial skin using the same it's about
최근 얼굴 피부의 미용 관리에 대한 관심이 폭넓게 증가하고 있다. 사람들은 피부관리실이나 마사지샵, 피부과의원 등 다양한 경로를 통하여 얼굴 피부의 상태를 확인하고, 적절한 화장품이나 약품 등을 사용하며, 이를 통해 얼굴 피부에 대한 관리 및 치료를 하고 있다.Recently, interest in cosmetic management of facial skin has been widely increased. People check the condition of facial skin through various channels such as skin care rooms, massage shops, and dermatologists, and use appropriate cosmetics or drugs, and through this, they manage and treat facial skin.
얼굴 피부 상태는 계절에 따라서도 변화되고 개인마다 차이가 있기 때문에 적절한 관리 및 치료를 위해서는 얼굴 피부 상태를 정확하게 진단하는 것이 매우 중요하다.Because facial skin conditions change with seasons and there are individual differences, it is very important to accurately diagnose facial skin conditions for proper management and treatment.
얼굴 피부 상태를 진단하기 위한 종래의 얼굴 영상 촬영장치는 얼굴 피부에 대한 영상을 획득하는 장치로서 피부 질환 및 피부 상태에 따라 의사가 환자의 피부치료 및 진단에 도움을 주는 역할을 수행하며, 형광과 편광을 이용하여 관찰하고자 하는 피부 상태를 분석하는 피부 영상 분석 시스템의 적어도 일부 구성부로 포함되기도 한다.A conventional facial imaging apparatus for diagnosing a facial skin condition is a device for acquiring an image of the facial skin, and plays a role of helping a doctor in treating and diagnosing a patient's skin according to a skin disease and skin condition. It is also included as at least some components of a skin image analysis system that analyzes a skin condition to be observed using polarized light.
그러나 종래의 얼굴 영상 촬영장치에 있어서 일반 광 분위기에서 촬영된 영상만으로는 다양한 피부 문제에 대한 분석이 어렵다. 따라서 최근에는 비디오 스코프와 같은 일반 피부 영상장비와 형광 및 편광 영상 장비와 같은 기능성 영상 장비를 더 사용하나, 기존의 피부 진단 장치용 얼굴 영상 촬영장치는 단순 작동 모드로 구성되어 있어, 진단 가능한 피부 상태의 개수가 제한되고, 접촉식 측정으로 인하여 진단자의 장치 사용 능력이나 피진단자의 서로 다른 피부 상태에 따라 재현성이 크게 떨어지는 한계가 있다.However, in the conventional face image photographing apparatus, it is difficult to analyze various skin problems only with images photographed in a general light atmosphere. Therefore, in recent years, general skin imaging equipment such as video scopes and functional imaging equipment such as fluorescence and polarization imaging equipment are more used. There is a limit in that the number of tests is limited, and the reproducibility is greatly reduced depending on the diagnostician's ability to use the device or the patient's different skin conditions due to contact measurement.
이러한 문제를 해결하기 위한 진단 장치로서, 대한민국 등록특허공보 제10-0853655호(이하, '종래기술 1'이라 함.)에 개시된 바와 같이 형광과 편광이 따로 분리되어있는 단일 모드의 영상진단 시스템이 주류를 이루었으며, 최근 들어, 백색광과 자외선을 이용한 컬러 영상과 형광 영상을 진단하는 영상 시스템이 출시되었기는 하지만, 백색광을 사용하여 피부 영상을 획득하는 경우 피부 표면의 정반사를 고려하지 않았으며, 형광영상의 경우 광원의 안정성과 조사도가 일정하지 않아 신뢰성이 떨어지는 문제가 예상된다.As a diagnostic device to solve this problem, as disclosed in Korean Patent Registration No. 10-0853655 (hereinafter referred to as 'prior art 1'), a single-mode imaging diagnostic system in which fluorescence and polarization are separated is provided. Although an imaging system for diagnosing color images and fluorescence images using white light and ultraviolet light has been released recently, specular reflection of the skin surface is not considered when acquiring a skin image using white light, and fluorescence In the case of images, reliability of the image is expected to decrease because the stability and irradiation degree of the light source are not constant.
또한, 대한민국 공개특허공보 제10-2014-0028415호(이하, '종래기술 2'이라 함.)의 피부분석을 위한 3차원 얼굴 모델 생성 장치 및 그 방법은, 복수개의 카메라를 이용하여 촬영 대상자의 얼굴을 다 각도로 촬영함으로써, 피부 분석을 위한 3차원의 사실감 있는 얼굴 모델을 생성할 수 있도록 하고, 촬영 대상자의 얼굴 촬영시 서로 다른 종류의 조명을 순차적으로 변경하여 제공함으로써, 조명별 특성을 이용한 피부 텍스쳐를 생성할 수 있는 기술을 개시하고 있다.In addition, the apparatus and method for generating a three-dimensional face model for skin analysis of Republic of Korea Patent Publication No. 10-2014-0028415 (hereinafter referred to as 'Prior Art 2') of the Republic of Korea Patent Publication No. 10-2014-0028415, using a plurality of cameras, By photographing the face from multiple angles, it is possible to create a three-dimensional realistic face model for skin analysis, and by sequentially changing and providing different types of lighting when photographing the subject's face, Disclosed is a technique capable of generating a skin texture.
그러나 종래기술 2는, 촬영 대상자의 얼굴을 다각도로 촬영하여 3D 얼굴 모델을 생성하기 위한 복수개의 카메라와, 서로 다른 종류의 조명을 제공하기 위해, 백색광 또는 편광 또는 UV(ultraviolet)광을 조사하는 복수개의 광원을 촬영 박스의 일면에 배치한 구성으로, 얼굴과 카메라 및 광원의 거리가 배치위치에 따라 차이가 있어 정확한 3차원(3D) 얼굴 모델을 생성하기 어렵고, 얼굴의 정면과 측면에 조사되는 광원의 밝기가 균일하지 않아 양질의 영상을 얻기 어렵다. 따라서 모공, 색소침착, 주름, 유분, 수분, 탄력 피부톤 피부온도, 다크써클 등 얼굴의 여러 곳에서 발생할 수 있는 다양한 피부 문제에 대하여 정확한 분석이 어려운 문제가 있다.However, in the prior art 2, a plurality of cameras for generating a 3D face model by photographing a subject's face from multiple angles, and a plurality of irradiating white light or polarized light or UV (ultraviolet) light to provide different types of illumination The light source is arranged on one side of the shooting box, and the distance between the face and the camera and the light source varies depending on the arrangement position, making it difficult to create an accurate three-dimensional (3D) face model, and the light source irradiated to the front and side of the face It is difficult to obtain high-quality images because the brightness of the image is not uniform.

(23) can be reduced.
이러한 본 실시예의 구성은 단순히 조명 모듈과 카메라 모듈과 조명 모듈 순으로 배치하여 얼굴 표면의 3D 입체 이미지를 획득하는 것과는 구별되며, 기하학적 돌출 평면 구조를 갖는 내면에 종횡으로 여러 단을 구성함으로서, 효과적으로 얼굴 피부의 3차원 이미지를 획득할 수 있다.The configuration of this embodiment is different from simply arranging the lighting module, the camera module, and the lighting module in the order to obtain a 3D stereoscopic image of the face surface, and by configuring several stages vertically and horizontally on the inner surface having a geometric protruding planar structure, the face effectively A three-dimensional image of the skin can be obtained.
또한, 조명 모듈(23)의 조명 모드를 제어함으로써 서로 다른 파장의 광 조사를 통해 다양한 촬영 이미지를 효과적으로 획득할 수 있다. 여기서, 조명 모드는 LED와 교차 편광필터에 의한 일반모드(교차편광), LED와 병렬 편광필터에 의한 광 조사가 조합되는 차등조명모드(병렬 편광), 그리고 자외선(UV) LED와 자외선(UV) 필터에 의한 자외선 조사가 함께 수행되는 UV모드로 구분할 수 있다.In addition, by controlling the illumination mode of the illumination module 23 , it is possible to effectively acquire various photographed images through light irradiation of different wavelengths. Here, the lighting mode is a normal mode (cross polarization) by LED and cross polarization filter, a differential lighting mode in which light irradiation by LED and parallel polarization filter is combined (parallel polarization), and ultraviolet (UV) LED and ultraviolet (UV) light. It can be divided into a UV mode in which UV irradiation by a filter is performed together.
일반모드는 교차 편광촬영(Cross Polarization)으로서, 자연광 하의 피부 상태를 세부적으로 관찰할 수 있도록 18세트의 카메라 모듈(22)에 의하여 얼굴과 목의 18개 부위를 고해상도로 촬영하여 이미지를 획득할 수 있다.The normal mode is cross polarization, and 18 sets of camera modules 22 are used to capture 18 parts of the face and neck in high resolution so that the skin condition under natural light can be observed in detail. have.

차등조명모드는 도 8에 도시한 바와 같이 제1 편광필터(24a)와 제2 평광필터(24b)를 이용한 병렬편광촬영(Parallel Polarization) 방식을 이용하는 것으로서, 피부 표피층이나 진피층에 대한 피부 질감을 세부적으로 관찰할 수 있도록 18세트의 카메라 모듈(22)에 의하여 얼굴과 목의 18개 부위를 고해상도로 촬영하여 이미지 획득할 수 있다.The differential illumination mode uses a parallel polarization method using a first polarization filter 24a and a second polarization filter 24b as shown in FIG. 18 sets of camera modules 22 can be used to photograph 18 parts of the face and neck with high resolution so that the images can be obtained.
여기서, 차등조명모드에서 LED 등의 조명 모듈(23)에서 나오는 제1 광(B1)은 제1 편광필터(24a)에 의해 제1 편광 광으로서 사용자의 피부(2)의 조사되고, 그에 따라 제1 편광 광의 일부는 피부(2)의 표면에서 반사되고 다른 일부는 피부(2)이 표피층(2a)이나 진피층(2b)에서 반사된다. 그리고, 피부(2)의 표면에서 반사되는 제1 편광 광은 편광 방향으로 유지한 상태로 카메라 모듈(22)로 향하나, 사용자 피부(2)의 피하지방층(4) 상의 진피층(2b)에서 반사되는 제1 편광 광은 그 편광 방향이 변환되어 제2 편광 광(B2)으로 카메라 모듈(22)을 향해 진행할 수 있다. 이때, 제1 편광 광(B1)은 제2 편광필터(24b)에 의해 차단되어 카메라 모듈(22)에 전달되지 않고, 제2 편광 광(B2)의 일부는 표피층(2a)이나 진피층(2b) 내부의 다른 재질(주근깨, 점, 흠 등)을 경유하거나 다른 재질의 표면에서 반사되거나 굴절되어 진행할 수 있다.Here, in the differential lighting mode, the first light B1 emitted from the lighting module 23 such as the LED is irradiated to the user's skin 2 as the first polarized light by the first polarization filter 24a, and accordingly One part of the polarized light is reflected from the surface of the skin 2 and the other part of the skin 2 is reflected from the epidermal layer 2a or the dermis layer 2b. And, the first polarized light reflected from the surface of the skin 2 is directed to the camera module 22 while maintaining the polarization direction, but is reflected from the dermis layer 2b on the subcutaneous fat layer 4 of the user's skin 2 . The polarization direction of the first polarized light to be converted may be converted to travel toward the camera module 22 as the second polarized light B2 .
