Description

자외선 광원 유도 형광을 이용한 수중 기름 형광 영상화 장치 및 방법Underwater Oil Fluorescence Imaging Apparatus and Method Using Ultraviolet Light Source Induced Fluorescence
본 발명은 수중 기름을 영상화하는 영상화 장치에 관한 것으로, 더욱 상세하게는, 자외선을 이용하여 수중 기름으로부터 형광 현상을 유도한 후 이를 촬영하는 것에 의해 수중 기름 형광 영상을 얻을 수 있도록 하는 자외선 광원 유도 형광을 이용한 수중 기름 형광 영상화 장치 및 그 방법에 관한 것이다.The present invention relates to an imaging apparatus for imaging oil in water, and more particularly, ultraviolet light source-induced fluorescence to obtain an underwater oil fluorescence image by inducing fluorescence from oil in water using ultraviolet rays and then photographing it. The present invention relates to an underwater oil fluorescence imaging apparatus and a method thereof.
유조선 사고 등으로 해양에 유출된 기름은 해수표면에 주로 존재하나, 시간이 지남에 따라 기름이 서로 뭉쳐 타르볼의 형태로 수중에 가라앉아 이동하므로, 해상에서 수중에 존재하는 타르볼의 존재를 모니터링하기에는 어려움이 있다. Oil spilled into the ocean due to an oil tanker accident is mainly present on the surface of the sea, but it is difficult to monitor the presence of tarballs in the water at sea since oils gather together and sink in the water in the form of tarballs. There is this.
이러한 타르볼은 수중으로 이동을 하여 해안가나 수중의 식물에 부착되어 심각한 해양 생태계의 오염원으로 작용하기 때문에 해양유류오염사고 발생 후 효과적인 방제작업을 위해서는 해수표면의 기름뿐만 아니라, 수중의 타르볼의 존재 및 양태를 파악하는 수중 모니터링 작업이 요구된다.Since the tarball moves underwater and attached to the coastal or underwater plants to act as a pollutant of a serious marine ecosystem, the effective and effective control work after marine oil pollution incidents is not only the oil on the surface of the sea, but also the existence and aspect of the tarball in the water. Underwater monitoring tasks are required to identify these conditions.
또한 해양 유전의 석유시추작업 과정에서 발생하는 수중에서의 기름 유출과 석유시추시설의 파이프 손상 등으로 발생하는 기름 누출, 그리고 수중 송유관의 손상으로 인한 기름의 누출 현상 등은, 대형의 기름유출사고를 방지하기 위해서 해당 작업의 수행과정에 있어서 상시 모니터링 해야 하는 부분이다.In addition, oil spills caused by oil spills during offshore oil drilling operations and damage to pipes in oil drilling facilities, and oil leaks caused by damages to oil pipelines, can cause large oil spills. In order to prevent this, it is a part that should be constantly monitored in the execution of the work.
수중의 기름에 대한 모니터링을 수행할 수 있는 종래기술로는 대한민국 공개특허 제 10-2014-0029410 호 '오일-물 혼합물에서 물 질량 분율의 측정 방법 및 장치'(종래기술 1), 대한민국 등록특허 제 10-0789724 호의 '형광빛 측정에 의한 오일 산화도 실시간 모니터링 방법 및 장치'(종래기술 2), 대한민국 등록특허 제 10-1229372 호 '기름탐지시스템 및 이를 이용한 기름 탐지방법'(종래기술 3) 등이 있다.The prior art that can monitor the oil in the water is disclosed in Republic of Korea Patent Publication No. 10-2014-0029410 'Method and apparatus for measuring the mass fraction of water in the oil-water mixture' (Prior Art 1), Republic of Korea Patent No. 10-0789724, 'Method and device for real-time monitoring of oil oxidation degree by fluorescent light measurement' (Prior Art 2), Korean Patent No. 10-1229372 'Oil detection system and oil detection method using the same' (Prior Art 3), etc. There is this.
상기 종래기술 1은 파이프 내에 흐르는 오일-물 혼합물을 온도 변환기를 이용하여 온도를 변환시키면서 서로 다른 시간에 사운도 속도와 온도를 측정한 후, 온도에서 알려진 변화에 대하여 오일-물 혼합물에서의 사운도 속도의 변화를 질양 분율과 관련시켜 연산하는 것에 의해 오일-물 혼합물에서의 물의 질량 분율을 측정할 수 있도록 하는 기술을 개시한다.The prior art 1 measures the sound velocity and the temperature at different times while converting the temperature of the oil-water mixture flowing in the pipe using a temperature converter, and then the soundness in the oil-water mixture against the known change in temperature. A technique is disclosed that enables the mass fraction of water in an oil-water mixture to be determined by calculating the change in velocity in relation to the mass fraction.
상기 종래기술 2는 오일의 산화에 따른 형광빛 방출 비율의 변화를 측정하여 오일의 산화도를 측정하는 기술을 개시한다.The prior art 2 discloses a technique for measuring the degree of oxidation of oil by measuring the change in fluorescence emission rate according to the oxidation of oil.
상기 종래기술 3은 해수면에 누출된 기름의 야간 탐지를 위해, 인공위성에서 해수면의 복사량과 기름 오염에 따른 편광별 수직 또는 수평방출과 반사도 및 해수와 기름의 굴절 지수를 분석하는 것에 의해 기름의 위치를 탐지할 수 있도록 하는 기술을 개시한다.In the prior art 3, the position of oil is analyzed by analyzing the vertical or horizontal emission and reflectivity and the refractive index of seawater and oil by polarization according to the amount of sea surface radiation and oil contamination in the satellite for night detection of oil leaked on the sea surface. Disclosed a technique that enables detection.
그러나 상기 종래기술들은 강 또는 바다 등에서 기름 유출 사고가 발생하는 경우 수중 오일을 측정하는데는 적용되지 못하는 문제점을 가진다.However, the prior arts have a problem in that it is not applicable to measuring oil in water when an oil spill occurs in a river or the sea.
일반적으로 수중에 존재하는 기름의 모니터링 작업은 수심에 따라 잠수사나 잠수정을 이용하여 백색광의 수중 조명과 가시광대역의 수중 카메라를 이용하여 수중 기름의 이미지를 취득하는 모니터링 방법을 통해 수행된다.In general, the monitoring of oil in the water is performed by a diver or a submersible according to the depth of the monitoring method of acquiring the image of the oil in the water by using the underwater light of the white light and the underwater camera of the visible band.
그러나 수중의 탁도, 수중 환경, 기름의 존재 형태와 양상에 따라서 수중에서 기름의 이미지를 취득할 수 있는 정도에 차이가 크므로 앞서 제시한 수중 조명과 가시광대역의 카메라를 이용하여 정확한 기름의 존재 유무 및 양태를 파악하기에는 오랜 수중 작업 시간과 취득한 영상의 후처리 등의 분석 작업이 요구된다.However, there is a big difference in the degree of acquiring the image of oil from underwater according to the turbidity of the underwater, the underwater environment, and the type and pattern of oil present. And analysis of such aspects requires a long underwater working time and post-processing of acquired images.
이러한 단점을 보완하기 위해서 수중에서 소나(SONAR)나 초음파 카메라 등, 음파를 이용한 방법으로 기름을 모니터링하는 방법이 제안되고 있으나, 해당 방법의 경우 넓은 탐지 범위를 갖는 장점이 있는 반면에 정밀도가 떨어지고 해상도가 낮으며, 후방산란 등으로 인해서 근거리에 있는 기름을 탐지하기에는 부적합한 단점을 갖고 있다. In order to make up for this drawback, a method of monitoring oil by means of sound waves, such as sonar or ultrasonic camera, has been proposed. However, the method has the advantage of having a wide detection range, but the precision and the resolution are poor. It is low and has the disadvantage of being unsuitable for detecting oil at close range due to backscattering.
특히 수중의 시추설비나 송유관으로부터 발생하는 기름 누출 현상과 크기가 작은 수중의 타르볼을 파악하기 위해서는 높은 해상도와 근거리 모니터링이 가능한 기술을 이용하여 수중의 기름을 모니터링할 필요성이 있다.In particular, in order to identify oil leakage from underwater drilling facilities or oil pipelines and tarballs in small sizes, it is necessary to monitor the oil in the water by using a technology capable of high resolution and near field monitoring.
따라서 본 발명은 상술한 종래기술의 문제점을 해결하기 위한 것으로, 수중에 존재하는 기름 영상의 인식을 위해, 기름이 갖고 있는 물리 광학적인 특성인 형광 현상을 수중 UV 광원을 이용해 유도시키고, 가시광대역의 빛으로 발산하는 형광 이미지를 CCD 카메라를 사용하여 영상을 취득할 수 있는 자외선 광원 유도 형광을 이용한 수중 기름 형광 영상화 장치 및 방법을 제공하는 것을 목적으로 한다.Therefore, the present invention is to solve the above-mentioned problems of the prior art, in order to recognize the oil image existing in the water, the fluorescence phenomenon, which is a physical optical characteristic of the oil is induced by using an underwater UV light source, An object of the present invention is to provide an underwater oil fluorescence imaging apparatus and method using ultraviolet light source-induced fluorescence capable of acquiring an image of a fluorescence image emitted by light using a CCD camera.

상기 광원부(110)는 수중 특히, 태양광이 침투하지 못하는 심해에서 심해 환경이나 수중 물체로서의 기름(200)(기름 방울)를 모니터하기 위해 인공 광을 제공할 수 있다. 특히, 상기 광원부(100)는 수중의 기름(200)으로부터 형광을 유도할 수 있는 광으로서 자외선을 방출하도록 구성된다. 따라서 상기 광원부(110)에는 다수의 자외선 LED 또는 자외선 램프를 포함하여 구성될 수 있다.The light source unit 110 may provide artificial light to monitor the oil 200 (oil droplet) as a deep sea environment or an underwater object in the water, especially in the deep sea where sunlight does not penetrate. In particular, the light source unit 100 is configured to emit ultraviolet light as light capable of inducing fluorescence from the oil 200 in the water. Therefore, the light source unit 110 may include a plurality of ultraviolet LEDs or ultraviolet lamps.
상기 영상촬영부(120)는 자외선(UV)에 의해 형광 유도된 기름(200)으로부터 방출되는 형광인 특정 파장 대역의 가시광선을 입력 받아서 수중 기름 형광 영상(210, 도 3 참조)을 생성하고, 생성된 수중 기름 형광 영상(210)을 저장하도록 구성된다. 이때 기름 형광 영상(210)은 수중에 부유하는 다른 생물이나 이물질 등의 이미지와 명확히 식별될 것이 필요하다. 이를 위해 상기 영상촬영부(120)에는 기름 형광의 파장에 대응하는 가시광선 대역(400nm ~ 600nm)의 빛만이 입사되어 영상이 촬영될 것이 필요하다.The image capturing unit 120 receives the visible light of a specific wavelength band which is the fluorescence emitted from the fluorescence induced oil 200 by ultraviolet (UV) to generate an underwater oil fluorescence image 210 (see FIG. 3), It is configured to store the generated underwater oil fluorescence image 210. At this time, the oil fluorescence image 210 needs to be clearly identified with images of other organisms or foreign substances floating in the water. To this end, only the light in the visible light band (400 nm to 600 nm) corresponding to the wavelength of the oil fluorescence is incident on the image capturing unit 120, so that an image is to be photographed.
따라서 상기 광학필터부(121)는 상기 기름 형광의 파장에 대응하는 가시광선 대역(400nm ~ 600nm)의 빛만이 선택적으로 투과되는 방출 필터(Emission Filter)로 구성되어 상기 영상촬영부(120)의 전단에 장착된다.Accordingly, the optical filter unit 121 is composed of an emission filter through which only light in the visible light band (400 nm to 600 nm) corresponding to the wavelength of the oil fluorescence is selectively transmitted, and thus the front end of the image capturing unit 120. Is mounted on.
이와 같이 상기 영사촬영부(120)는 특정 대역의 파장을 가지는 빛만을 촬영하도록 구성되므로, 상기 광학필터부(121)에서 필터링된 기름의 형광의 빛에 의한 촬상 신호만을 생성하는 CCD(charged coupled device) 카메라를 포함하여 구성될 수 있다. As such, since the projection photographing unit 120 is configured to photograph only light having a wavelength of a specific band, a CCD (charged coupled device) generating only an imaging signal by the fluorescent light of oil filtered by the optical filter unit 121. It may be configured to include a camera.
또한, 상기 촬영된 수중 기름 형광 영상(210)을 저장하기 위해 상기 영상촬영부(120)는 내부에 영상저장부(미도시)를 더 포함하여 구성된다.In addition, the image capturing unit 120 further includes an image storage unit (not shown) to store the photographed underwater oil fluorescence image 210.
상기 제어부(130)는 상기 광원부(110)의 발광 시간과 영상촬영부(120)의 촬영시간을 동기화시켜 수중의 기름에서 형광을 유도하고, 기름으로부터 방출되는 영상을 자외선의 조사와 동시에 촬영하여 저장할 수 있도록 상기 광원부(110)와 영상촬영부(120)를 동시에 제어하도록 구성된다.The controller 130 induces fluorescence in the oil in the water by synchronizing the light emission time of the light source unit 110 and the image capturing time of the image capturing unit 120, and simultaneously captures and stores the image emitted from the oil with irradiation of ultraviolet rays. It is configured to control the light source unit 110 and the image capturing unit 120 at the same time.
상술한 구성을 가지는 본 발명의 수중 기름 형광 영상화 장치(100)는 수중에서의 사용을 위해 방수 처리될 수 있고, 별도의 방수 케이스에 일체로 내장 설치될 수도 있다.The underwater oil fluorescence imaging apparatus 100 of the present invention having the above-described configuration may be waterproofed for use in water, or may be integrally installed in a separate waterproof case.
도 2는 본 발명의 실시예에 따르는 자외선 광원 유도 형광을 이용한 수중 기름 형광 영상화 방법의 처리과정을 나타내는 순서도이다.2 is a flowchart illustrating a process of the underwater oil fluorescence imaging method using ultraviolet light source induced fluorescence according to an embodiment of the present invention.

It is made to include.
상기 자외선조사과정(S10)에서 제어부(130)의 제어에 따라, 광원부(110)에 의해 자외선이 수중으로 발산된다. 수중으로 발산된 자외선은 수중의 기름 방울 등의 기름(200)에 의해 흡수되어 기름의 형광을 유도한다. 형광이 유도된 기름에서는 400 nm ~ 600 nm 대역의 가시광선이 형광으로 방출된다.Under the control of the control unit 130 in the ultraviolet irradiation process (S10), the ultraviolet light is emitted into the water by the light source unit 110. The ultraviolet rays emitted into the water are absorbed by the oil 200 such as oil droplets in the water to induce fluorescence of the oil. Fluorescently induced oils emit visible light in the 400 nm to 600 nm band.
상기 수중 기름 형광 필터링과정(S20)에서는, 기름 형광 영상(210)이 다른 이미지와의 명확히 식별될 수 있도록, 방출 필터로 구성되는 광학필터부(121)가 기름 형광의 파장에 대응하는 가시광선 대역(400nm ~ 600nm)의 빛만을 영상촬영부(120)로 입사되도록 투과시킨다.In the underwater oil fluorescence filtering process (S20), the optical filter unit 121 configured as the emission filter has a visible light band corresponding to the wavelength of the oil fluorescence so that the oil fluorescence image 210 can be clearly distinguished from other images. Only light of 400nm to 600nm is transmitted to be incident on the image capturing unit 120.
상기 수중 기름 형광 영상 촬영 과정(S30)에서는, 상기 자외선조사과정(S10)에 의해 기름의 형광이 유도되어 방출된 후 상기 광학필터부(121)에 의해 선택되어 입사되는 400 nm ~ 600 nm 대역의 가시광선을 영상촬영부가(120)가 수광하여 촬상하는 것에 의해 수중 기름 형광 영상을 생성한다.In the underwater oil fluorescence imaging process (S30), the fluorescence of the oil is induced by the ultraviolet irradiation process (S10) is emitted after the emission of 400 nm ~ 600 nm band selected by the optical filter unit 121 The image pickup unit 120 receives and captures visible light to generate an underwater oil fluorescence image.
상기 수중 기름 형광영상 기록과정(S40)에서는 영상촬영부(120)가 촬영된 수중 기름 형광 영상을 영상촬영부(120) 내의 하드디스크, 플래시 메모리 등의 영상저장부(미도시)에 저장한다.In the underwater oil fluorescence image recording process (S40), the oil fluorescence image captured by the image capturing unit 120 stores the captured oil fluorescence image in an image storage unit (not shown), such as a hard disk, a flash memory, in the image capturing unit 120.
도 3은 촬영된 기름 형광 영상의 예를 나타내는 도면이다.3 is a diagram illustrating an example of a photographed oil fluorescence image.
도 3은, 상술한 도 1의 구성을 가지는 수중 기름 형광 영상화 장치(100)를 이용하여 도 2의 수중 기름 형광 영상화 방법의 처리과정을 수행하여 촬영된 수중 기름 형광 영상을 나타낸다. 도 3과 같이, 수중 기름에 형광을 유도한 후, 기름에서 방출되는 형광만을 필터링하여 입사키는 것에 의해 기름 이외의 다른 물질들의 영상은 제거된 후 수중 기름 형광 영상(210)만이 촬영된다. 따라서 주변 환경은 수중이 되므로 수중 내에서의 기름 방울(타르볼)의 형상 및 분포 등이 명확하게 표시되므로, 수중의 기름에 의한 오염 정도를 명확하게 확인할 수 있게 된다.3 illustrates an underwater oil fluorescence image photographed by performing the process of the underwater oil fluorescence imaging method of FIG. 2 using the underwater oil fluorescence imaging apparatus 100 having the configuration of FIG. 1. As shown in FIG. 3, after inducing fluorescence in the oil in water, only the oil fluorescence image 210 is photographed after the image of other materials other than the oil is removed by filtering and injecting only the fluorescence emitted from the oil. Therefore, since the surrounding environment becomes underwater, the shape and distribution of oil droplets (tarballs) in the water are clearly displayed, and thus the degree of contamination by oil in the water can be clearly confirmed.
