오늘날 디스플레이 기술의 진화는 건축물의 외벽은 물론 조형물에 영상을 구현할 수 있게 되었다. 프로젝션 맵핑은 입체감 있는 가상영상을 실내외는 물론 조형물에 덧입힘으로서 새로운 공간으로 탈바꿈시키는 영상표현 방법의 하나이다. 본 연구에서는 프로젝션 맵핑 제작과정에 있어서 색보정이 영상의 입체감에 영향이 미치는지 실험을 통해 검증하고 이를 통하여 프로젝션 맵핑제작에 있어서 효과적인 프로세서에 대한 정보를 제공 하고 확립하는 것이 본 연구의 목적이다. 프로젝션 맵핑은 예술뿐만 아니라 산업전반에 영향력을 주고 있다. 이처럼 새로운 디지털 기술에의한 미디어의 발달과 미디어의 발달에 따른 새로운 표현양식의 등장은 앞으로도 계속될 것이다. 본 연구를 토대로 프로젝션 맵핑 제작에 있어서 유익한 연구의 기초로 활용되었으면 한다.

Software tools for manual 3D projection mapping have been widely used in theme parks and exhibitions. However, no research has been conducted on detailed utilization methods and usability of those tools yet. This study organizes the entire process of manual 3D projection mapping step by step and analyzes the problems that occurred at each step to identify potential improvements of 3D projection mapping tools. First, we introduce the process, which includes: two methods for creating virtual-physical object pairs to construct a virtual environment that is identical to the real-world target of the 3D projection mapping, the production of video textures for special effects, and mapping methods that use semi-automatic projector calibration. In addition, through experiments comparing and analyzing two widely used tools under various conditions for 3D mapping, we identified the technical limitations, performance differences between tools, and issues that impede usability. Finally, we suggest improvements and future research directions to enhance the usability of the 3D projection mapping technology.

In recent, projection mapping, which has attracted high attention in the field of realistic media, is regarded as a technology to increase the users' immersion. However, most existing methods perform projection mapping on static objects. In this paper, we developed a technology to track the movements of users and dynamically map the media contents to the users' bodies. The projected media content is built by predefined gestures just using the user's bare hands without the special devices. An interactive immersive media system has been implemented by integrating these dynamic projection mapping technologies and gesture-based drawing technologies. The proposed realistic media system recognizes the movements and open / closed states of the user 's hands, selects the functions necessary to draw a picture. The users can freely draw the picture by changing the color of the brush using the colors of any real objects. In addition, the user's drawing is dynamically projected on the user's body, allowing the user to design and wear his t-shirt in real-time.

Projection mapping is one of the convergence contents combined with digital technology. After entering the Chinese market, with its fantastic shock of visual impact, it becomes China's most shocking, most popular, and most commercial value of marketing means, to be widely used in advertising, construction, tourism and other fields. But in China, the lack of projection mapping professionals and professional will affect the development of the entire industry. The study analysed the case of projection mapping in China, and discovered the future direction development of projection mapping. Projection mapping will keep going based on local cultural environment, and combined with other intelligent technologies, and spreading to daily life, also expanding the using area, creating the manifestation pattern then contributing greatly to the entertainment content industry.

본 연구는 촬영을 통해 얻어진 투사면을 이용하여 투사면과 프로젝터 사이의 거리를 측정하고, 이미지 내에서 투사면이 가질 수 있는 영상의 원근 왜곡을 보정하는 프로젝션 맵핑에 대한 영상처리 기술을 제안한다. 그리하여, 결과적으로 프로젝터의 초기 설치에 소요되는 시간을 줄이고 변화된 투사면에 적합하게 프로젝션 맵핑이 이뤄짐에 따라 프로젝션 맵핑의 완성도를 높이고자 한다.

본 논문에서는 임의의 2차원 프로젝션 맵핑 공간을 인터랙티브 공간으로 구축할 수 있도록 하는 인터랙티브 프로젝션 맵핑 프레임워크를 제안하고, 제안 프레임워크를 활용한 "애니마블" 게임 구현 사례를 소개한다. 제안 프레임워크는 프로그래밍 스킬이 전혀 없는 창작자들이 물체 감지 기술을 이용하여 인터랙티브 미디어 콘텐츠를 쉽게 제작할 수 있도록 하기 위하여 설계 구현되었다. 콘텐츠 창작자는 인터랙션이 발생될 위치를 카메라 영상상에서 지정하고, 미리 지정된 파일 디렉토리에 정해진 룰에 따라 이름 지어진 미디어 콘텐츠 파일들을 가져다 놓는 것만으로 인터랙티브 프로젝션 맵핑 콘텐츠를 완성할 수 있다. 제안 프레임워크를 이용한 "애니마블" 게임은 아날로그적 보드게임과 미디어 콘텐츠를 결합한 아동용 인터랙티브 미디어 보드게임으로 구현되었다.

Recent advances in new media for sensory experiences keep expanding visual expression methods in installation art such as projection mapping and virtual reality. Artists can create and develop visual expression techniques based on such new media. Projection mapping is a new medium that continues to add various possibilities to visual expression in media art. Under the projection mapping environment, artists can recompose the object or space with the digital content by projecting video onto three-dimensional surfaces in the space. This paper focuses on the process where visual expression with the projection mapping technology leads to viewers' sensory experience. To this end, "reproducibility," "dissemination," "virtuality," and "interactivity" of media were analyzed to describe the meaning and *definition of visual expression. Artworks are considered as an example to study visual expression techniques such as "repetition and overlap," "simulacrum and metaphor," and "displacement and conversion." I applied the analysis and created Domino, a projection mapping artwork, which helps the research on visual expression techniques that can lead to sensory experience the extensibility of visual expression.

This paper studies the current development of personal media and the development of project mapping technology. The speed of social life is speeding up, and information dissemination tends to be fragmented. With the rapid development of mobile technology in recent years, personal media has gradually attracted the attention of people. And now image production and video editing become more and more simple in mobile devices, which provide a basis for the active personal media. The emergence of video content with high creative which is producing by projection mapping. And also providing an attractive new content for the general public. With the popularity of home projector, and the development of mobile terminal projection mapping production application. In the future, it will be possible to use projection mapping to produce personal media contents on the basis of mobile media platform.

The range of art has been gradually expanded with the passage of time. Science and technology have also contributed to the arts in the name of media art, and artists and technicians have become collaborative. In this paper, we investigate the meaning of collaboration in art and analyze the case focusing on Projection Mapping which is a field of Media Art. In particular, this study propose the concept and production process of Sequential Collaborative Projection Mapping works, and see the work of making and exhibition as one experiment. Based on this, sequential collaborative procedures are defined in the case of work production, and the underlying technologies and procedures for collaboration are presented. The presented techniques and procedures can be applied to projection mapping exhibitions and festivals as a platform. In this process, we have reviewed the collaborative relationship between artists and technicians, and the issues with regard to giving and receiving the credit of works.
