Abstract

The measuring system uses a video camera to provide an enlarged image of the skin surface on a video screen. This image is converted into an image with two brightness values before being projected onto a further video screen esp. designed for a 2-value brightness image. A manually adjusted knob is used to determine the brightness values of the brightest and darkest points of the image on the second screen by adjustment until they are black or white respectively, the values being indicated by a display, the required depth being obtained from the difference between them.

본 발명은 피부표면에 있어서의 피구 및 주름의 깊이를 비데오 카메라를 이용하여서 측정하는 장치에 관한 것이다.The present invention relates to an apparatus for measuring the depth of the dodgeball and wrinkles on the skin surface using a video camera.

사람의 피부는 육안으로서 관찰하였을 경우에 평탄하게 보이는 것이라도 실제로는 표면에서 높게 되어있는 피구(皮丘), 낮게 홈으로 되어있는 피구 혹은 주름 등에 의하여 미세한 그물모양으로 되어있는 것이다. 그리고 일반적으로 젊은 사람일수록 피부는 가늘고, 연령과 더불어 피구가 깊게 되거나 주름이 생기거나 하는 경향에 있다. 그래서 종래로부터 의료진단이나 화장(化粧)함에 있어서의 피부의 상황판단을 목적으로 하여 실리콘 수지를 피부에 압압부착하여 피부의 형(型)을 채취한 후에 피부의 깊이를 현미경으로서 측정한다고 하는 수단이 채용되고 있었다. 그러나, 이와 같은 측정방법에 있어서는 실리콘 수지로서 형을 채취함에는 기능의 숙달을 필요로 하거나, 현미경으로서 깊이를 측정함에는 고도의 기술을 필요로하는 등의 이유로서 간단하게는 측정할 수 없다고 하는 불편이 있었다.Although human skin looks flat when observed with the naked eye, it is actually a fine net shape due to a high dorsal ball on the surface, a low groove or a crease. In general, younger people tend to have thinner skin, age, and deeper dorsal wrinkles. Therefore, conventionally, a means of measuring the depth of the skin as a microscope after pressing a silicone resin onto the skin and collecting the skin shape for the purpose of determining the condition of the skin during medical diagnosis or make-up It was adopted. However, in such a measuring method, it cannot be measured simply because of the mastery of a function required to collect a mold as a silicone resin, or a high skill to measure the depth as a microscope. There was inconvenience.

그래서 본 발명은 이러한 종래의 측정수단의 결점에 비추어서 측정이 용이함과 아울러 측정이 정확하게 행할 수 있는 것 및 어떠한 사람이라도 측정을 가능하게 하는 것을 목적으로 한다. 즉 본 발명은 비데오 카메라와, 비데오 카메라의 영상을 비추는 모니터 텔레비와, 모니터 텔레비의 영상을 이원화하여서 이치화전용 모니터 텔레비에 이치화 화상을 비추어내는 비데오 패턴센서로서 이루어지며, 비데오 패턴센서가 수치화된 손잡이의 작동에 의하여 이치화 전용 모니터 텔레비의 화상을 임의의 스레시홀드로 설정 가능하도록 구성된 것으로서 이루어진다.Therefore, an object of the present invention is to make it easy to measure in the light of the shortcomings of the conventional measuring means, to be able to perform the measurement accurately, and to make it possible for anyone to measure. That is, the present invention is made of a video camera, a monitor television for illuminating the video of the video camera, and a video pattern sensor for illuminating the binarized image on the monitor television dedicated to the binarization by dualizing the image of the monitor television. By operation, the image of the dedicated monitor television set is configured to be set to an arbitrary threshold.

또 본 발명은 상기한 장치를 사용하여 비데오 카메라로서 피부표면을 확대하여 모니터 텔레비에 화상을 비추어내는 조작과, 모니터 텔레비의 화상을 이원화하여서 이치화전용 모니터 텔레비에 비추어내는 조작과, 피구(皮丘)의 가장 밝은 부분이 이치화 전용 모니터 텔레비에 있어서 검게될 때까지 스테시홀드용 손잡이를 조정하여 그때의 수치를 측정하는 조작과, 피구의 가장 어두운 부분이 이원화 전용모니터 텔레비에 있어서 희게될 때까지 스레시홀드용 손잡이를 조정하여 그때의 수치를 측정하는 조작으로서 이루어지는 측정방법에 관한 것이다.In addition, the present invention uses the above-described apparatus to enlarge the skin surface as a video camera to illuminate the image on the monitor television, to dualize the image of the monitor television, and to illuminate the monitor television exclusively for binarization; Adjust the stabilization knob to measure the value until the brightest part of the monitor is black on the dedicated monitor television, and thresh until the darkest part of the dodgeball becomes white on the dual monitor television. It relates to a measuring method which is performed as an operation of adjusting the holding knob and measuring the numerical value at that time.

이하, 제1도 내지 제3도에 표시된 실시예에 따라서 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail according to the embodiments shown in FIGS. 1 to 3.

도면에 있어서,In the drawings,

(1)은 영상 해석용 비데오 카메라이며, 비데오 카메라(1)에는 그 배율을 10~100배로 하기 위한 C마운트 렌즈(2)가 장착되어 있다.(1) is a video camera for video analysis, and the video camera (1) is equipped with a C-mount lens (2) for increasing the magnification 10 to 100 times.

또 C마운트 렌즈(2)의 앞쪽 끝부분에는 광원장치(3)를 광원으로 하고, 앞쪽 끝 외주에서 약 10mm 떨어진 피부면을 조사하도록 구성된 광학유리섬유(4)를 내부에 가지고 있는 경질(硬質)의 파이버 스코오프(5)가 부착되어 있다.The front end of the C-mount lens 2 has a light source device 3 as a light source, and a hard fiber having optical glass fibers 4 configured to irradiate the skin surface about 10 mm away from the outer periphery of the front end. Is attached to the fiber scope 5.

비데오 카메라(1)는 비데오 테이프 레코오터(6)에 접속되어 있으며, 비데오 테이프 레코오터(6)는 또다시 그 영상을 비추어내는 모니터 칼라텔레비(7)에 접속되어 있다.The video camera 1 is connected to the video tape recorder 6, and the video tape recorder 6 is again connected to the monitor color television 7 which illuminates the image.

다음에 모니터 칼라텔레비(7)는 비데오 신호를 이원화하여서 이원화전용 모니터텔레비(8)에 이원화화상을 비추어내는 비데오패턴센서(9)에 접속되어 있다.Next, the monitor color television 7 is connected to the video pattern sensor 9 which binarizes the video signal and projects the binary image onto the monitor television 8 dedicated to the dualization.

이 비데오 패턴센서(9)는 모니터 텔레비(8)의 이원화된 화상의 명도를 임의의 스레시홀드로 설정할 수 있는 손잡이(10)와 손잡이(10)의 수치를 표시하는 인디케이터(11)를 보유하고 있다. 또한 본 실시예에 있어서는 인디케이터(11)의 수치를 콤퓨터(12)에 입력할 수 있도록 구성되어 있다.The video pattern sensor 9 has a knob 10 which can set the brightness of the dualized image of the monitor television 8 to an arbitrary threshold and an indicator 11 displaying the numerical value of the knob 10. have. In this embodiment, the numerical value of the indicator 11 is configured to be input to the computer 12.

이상 설명한 바와 같은 구성에 있어서 본 발명에 관한 장치는 이하와 같이 사용한다.In the configuration as described above, the apparatus according to the present invention is used as follows.

먼저 비데오 카메라(1)에 장착된 파이버 스코오프(5)를 피부표면에 닿게 하여 광학유리섬유(4)로서 빛을 조사하면서 소정의 배율(예컨대 100배)로 비데오 카메라(1)에 의하여 피부표면을 확대하여서 모니터텔레비(7)에 비추어낸다. 비추어낸 피부표면의 화상은 참고자료로서 첨부한 사진(1)에 표시된 바와 같이 피구가 어둡고, 또 피구(皮丘)가 밝게 되어 있다.First, the fiber scooff 5 mounted on the video camera 1 touches the skin surface and irradiates light with the optical glass fiber 4 while the skin surface is exposed by the video camera 1 at a predetermined magnification (for example, 100 times). Zoom in on the monitor television (7). As shown in the attached photograph (1) as a reference, the image of the surface of the skin which has been illuminated is darker in the figure, and the figure is brighter.

이 모니터텔레비(7)의 비데오신호를 비데오 패턴센서(9)에 입력하여서 이치화하여 참고자료로서 첨부한 사진(2)에 표시된 바와 같이 이치화 전용모니터 텔레비(8)에 화상을 비추어낸다. 다음에 모니터텔레비(7)를 보고 피구(皮丘) 중에서 가장 밝은 부분과 피구(皮丘)를 포위하는 피구 또는 피구(皮丘)에 가까운 주름 중에서 가장 어두운 부분을 결정한다. 그리고 비데오 패턴센서(9)의 스레시홀드 설정용의 손잡이(10)를 작동시켜서 먼저 정한 가장 어두운 부분이 이원화 전용 모니터 텔레비(8)에 있어서 희게될 때의 인디케이터(11)의 수치를 읽는다(수치를 Lmin으로 한다).The video signal of the monitor television 7 is inputted to the video pattern sensor 9 and binarized, and the image is displayed on the binarized monitor television 8 as shown in the attached photograph 2 as a reference. Next, the monitor television (7) is used to determine the brightest part of the dodgeball and the darkest part of the dodgeball or the closest wrinkles surrounding the dodgeball. Then, the knob 10 for setting the threshold of the video pattern sensor 9 is operated to read the numerical value of the indicator 11 when the darkest portion determined first becomes white in the dual monitor dedicated television (value). Is Lmin).

또 정하여진 가장 밝은 부분이 이원화 전용모니터 텔레비(8)에 있어서 검게될 때의 손잡이(10)의 인디케이터(11)의 수치를 읽는다(수치를 Lmax로 한다).In addition, the value of the indicator 11 of the knob 10 is read when the brightest part determined is black on the dual monitor-only television (the value is Lmax).

이 측정값 Lmin과 Lmax을 각각 콤퓨터(12)에 입력한다. 그리고 측정값 Lmin과 Lmax와의 차(명도차)에 사전에 산출하여 놓은 명도와 깊이와 환산계수(K)를 곱하면 피구 또는 주름의 길이를 계산할 수가 있다.These measured values Lmin and Lmax are input to the computer 12, respectively. By multiplying the difference (brightness difference) between the measured values Lmin and Lmax by the previously calculated brightness, depth and conversion factor (K), the length of the dodgeball or wrinkles can be calculated.

이상 설명한 바와 같이 본 발명에 관한 장치를 이용하면, 단순히 측정하는 장소를 결정하여서 스레시홀드 설정용의 손잡이를 조정하여 그 수치를 읽는다고 하는 비교적 간단한 방법이면서도 측정의 신속 또는 정확하게 행할 수가 있으므로 종래의 측정수단보다도 우수한 것을 얻을 수가 있다.As described above, the apparatus according to the present invention can be quickly or accurately measured while being a relatively simple method of simply determining a measurement position and adjusting a threshold setting knob to read the numerical value. It can obtain what is superior to a measuring means.
