4차 산업의 주요 기술로 실감형 360도 영상 콘텐츠가 주목받고 있다. 전 세계 실감형 360도 영상 콘텐츠의 시장 규모는 2018년 67억 달러에서 2020년 약 700억 달러까지 증가될 것이라고 전망하고 있다. 하지만 대부분 실감형 360도 영상 콘텐츠가 웹하드, 토렌트 등의 불법 유통망을 통해 유통되고 있어 불법복제로 인한 피해가 증가하고 있다. 이러한 불법 유통을 막기 위하여 기존 2D 영상은 불법저작물 필터링 기술을 사용하고 있다. 그러나 초고화질을 지원하고 두 대 이상의 카메라를 통해 촬영된 영상을 하나의 영상에 담는 실감형 360도 영상 콘텐츠의 특징 때문에 왜곡 영역이 존재하여 기존 2D 영상에 적용된 기술을 그대로 사용하기엔 다소 무리가 있다. 또한, 초고화질에 따른 특징점 데이터량 증가와 이에 따른 처리 속도 문제와 같은 기술적 한계가 존재한다. 본 논문에서는 이러한 문제를 해결하기 위하여 왜곡이 심한 영역을 제외한 객체 식별 영역을 선정하고, 식별 영역에서 딥 러닝 기술을 이용하여 객체를 인식하고 인식된 객체의 정보를 이용하여 특징 벡터를 추출하는 특징점 추출 및 식별 방법을 제안한다. 제안한 방법은 기존에 제안 되었던 스티칭 영역을 이용한 실감형 콘텐츠 특징점 추출방법과 비교하여 성능의 우수성을 보였다.

For the purpose of this Study, the situation of Korean costume properties in the collection of overseas museums was investigated through correspondence, interviews with their curators and persons in charge and survey. As results were made about the situation of museum science (conservation) and practical utilization of costume properties. So, the study result were drawn as follows : Krean costume properties unexplaind of 'Korean cultural Properties' could be found in the Metropolitan Museum of Art of New York(135 pieces), the Brooklyn Museum of New York(20 pieces), the Newark Museum of New Jersey(15 pieces), and the Victoria Albert Museum of London(100 pieces). Korean costume properties in the collection of over-seas museums mostly fall under the rang of period between the 19th century and the early 20th century and are classified into everyday clothing, wedding costume and armors for the most part. In 1900s, museum in several countries began to collected Korean cultural properties through foreign missionaries or diplomats as well as merchants or travellers in who bought Korean objects. Recently, scholars, traditional Korean costume designerss and diplomatic and consular offices in overseas have donated our Korean costume to many foreign museums. Korean costume properties were largely on display in the dependent display of folklore museums or in a part of exhibition gallery for Asian culture and there were the separate exhibition rooms in museums in the United Kingdom, Germany, Denmark, Austria, Japan and the United States America. But the size and level of display room for Korean cultural properties is one third as large as that for chinese or Japanese cultual properties. It was found in this study that the traditional Korean costume in the collection of overseas museums was largely recorded only as general items rather than given their proper names. The typical example of misnaming included bridal's Kimono for Wonsam(원삼) in the Metropolitan Museum of Art, Yeonroksaek-bumunsajeokori for Dangeui(당의) and Jissan-gryongwonmunsadurumagi for Kongdali(동달이) in the Okura collection of the Tokyo National Museum, and so on. And the Victoria Albert Museum modified the way of wearing Daenim(대님) and the National Museum of Ethnology in Osaka seemed to misplace the ornament of Keanggi(댕기) on Mubok(무복) and Josunjuk(조선족: Chinese-Korean) Museum also misplace hansam(한삼). On the one hand, the Newark museum of New Jersey mixed Chinese armor with the Korean one and the Photohraph of King Kojong(고종) with Chinese one. It is corrected to publish and disseminate the book concering Korean costume in order to inform foreign museums of thed proper names and wearing method of our traditional costumed. The repair of costume before cleaning in the process of conservation treatment can prevent damage likely to occur as the properties of fiber itself are weakened in liquid. It is recommended that western 8-figure stitch and tacking stitch is added to Korean traditional stitching method. Museums in the U.S.A and the U.K are concerned about the aftermath of cleaning it-self, specially conservation treatment may exert on remains and predominantly use the vacuuming method to remove dust or bits of straw before the exhibition beings. But in case of Korea, the dry cleaning and wet cleaning method are used according to the nature and state of a sample costume. This comprehensive cleaning method is gradually developing scientifically but it is expected that those concerned will make a chemical analysis of the solvent to be used and also the more precise test of costume properties will be conducted before cleaning them. A partial study was made here because the scope of study was too broad and vast. It is expected that more studies will be conducted concerning our costume culture under the long-term plan and active support at the government level.
