3D 모델링 기술은 가상현실, 실감형 인터랙티브 등에서 많은 연구가 진행되고 있다. 실시간 3D 모델을 생성하는 연구는 많은 계산량으로 인해서 여러 대의 PC를 통합한 PC클러스터를 사용하고 있다. PC클러스터는 여러 대의 PC를 하나의 고성능 컴퓨터로 처리가 가능하지만, 여러 대의 PC를 효율적으로 제어 하는 문제와 고비용의 문제를 안고 있다. 본 논문은 한 대의 PC에서 멀티 코어를 동시에 수행하는 병렬처리 방법과 높은 계산 능력을 자랑하는 GPU와 CPU의 병렬처리 방법을 사용하여 한 대의 컴퓨터로 실시간 3D 모델 생성방법을 제안한다.

The interaction using digital media has been widely utilized in modern art. In particular, network based digital media enables two-way and real-time communication regardless of time and place. Network is possible to connect to effective and meaningful communication of extended relationship. This study proposes novel human-MediaFacade interaction method through a mechanism on interworking between 3D mapping technology and social media, smart devices. This study has an important meaning which can be set multi-user interaction. And a study of creating 'Facade' which interaction has high artistic value.

In this paper, implementation of object-based multiview 3D display using object segmentation and adaptive disparity estimation is proposed and its performance is analyzed by comparison to that of the conventional disparity estimation algorithms. In the proposed algorithm, firstly we can get segmented objects by region growing from input stereoscopic image pair and then, in order to effectively synthesize the intermediate view the matching window size is selected according to the extracted feature value of the input stereo image pair. Also, the matching window size for the intermediate view reconstruction (IVR) is adaptively selected in accordance with the magnitude of the extracted feature value from the input stereo image pair. In addition, some experimental results on the IVR using the proposed algorithm is also discussed and compared with that of the conventional algorithms.

본 논문은 딱지본의 2D 이미지를 사용하여 3D 버츄얼 스페이스를 제작한 작품에 관한 글이다. 가상 공간에서 현실과 같은 활동이 활발히 이루어지고 있는 최근의 사회 현상에 관심을 두고, 딱지본의 이미지를 차용하여 과거의 낭만적인 시대를 여행하는 듯한 버츄얼 스페이스를 구현해 보았다. 이 작품은 포토샵 편집 과정을 거친 2D 이미지 파일들과 구글 3D 지도를 캡쳐하여 단계적 변환을 거친 3D 이미지 파일로 구성된다. 편집과 변환 과정을 거친 2D 와 3D 파일은 언리얼 엔진을 기반으로 화면에 배치하고 조합하여 버츄얼 스페이스를 제작한다. 2D 레트로 컨텐츠와 3D 가상 공간의 융합은 작품 제작에 있어 다양한 아이디어를 제공하고 새로운 표현 방식으로 확장 할 수 있는 가능성을 보여준다.

In this paper, a new stereo 3D moving-target tracking system using the MSE (mean square error) and BPEJTC (binary phase extraction joint transform correlator) algorithms is proposed. A moving target is extracted from the sequential input stereo image by applying a region-based MSE algorithm following which, the location coordinates of a moving target in each frame are obtained through correlation between the extracted target image and the input stereo image by using the BPEJTC algorithm. Through several experiments performed with 20 frames of the stereo image pair with $640{\times}480$ pixels, we confirmed that the proposed system is capable of tracking a moving target at a relatively low error ratio of 1.29 % on average at real time.

The problem of the conflict between eye convergence and accommodation can be induced at Stereoscopic or multi-view 3D display system using binocular disparity. A multi-focus 3D display system was developed, which can solve the problem. LEDs are used instead of galvano scanner and laser to avoid mechanical moving part at the 3D display system.

The 3D animation these days is confronted with a situation that should develop new contents fit for those circumstances of media in which new platforms such as smart phones, tablet PCs, and smart TVs, etc. are in a rapid change and establish media strategies. Attempts are made of developing methods to diversify content type coping with new smart media characteristics including smart phones, tablet PCs, and smart TVs, etc., with materials of the same story and character, and developing animation video contents based on new media technology. This study made avatas utilizing iClone, avata 3D production technology and investigated 3D animation production methods through costume editing and motion editing.

With the opening of digital broadcast services and development of wire/wireless Internet, the current multimedia broadcasting is provided for has various services. The user will be provided lots of various content through the various channel and media. Content provider and consumer want the various service using content with the better quality which is fit to user preference. For transmitting this content in the limited transmission channel capacity, it needs to transmit the highly compressed content which user wants. The content of 3D mesh model-based on MPEG-4 enables the various content service that provides the lower capacity and the better quality, and Targeting service enables just provide the contents that user more wants and likes. The adaption of Java application program and 3D program can provide the content service utilizing 3D mesh model, so content provider and consumer can share the more information about the content. This paper has presented the study on the targeting service using compression of 3D mesh model-based on MPEG-4 and the adaptation of Java application program using it

Recent promising technologies of the manufacturing sector interest, and the interest in 3D printing that is expected to cause a huge ripple effect rapidly, and various types of products advertised in accordance with the falling price of 3D printers is spreading. However, the personal 3D printers that are currently being advertised is used for Injection output of the simple type that does not require a high processing precision in accordance with the limitation of technical performance, and consumer satisfaction is very low. In this paper, we propose a 3D printer, 3D precision to overcome existing limitations in the way the printer's high SLA 3D printer that combines injection method and the LSU (Laser Scanning Unit) in the office laser printer polygon mirror scanning method. 3D printers which are proposed to improve the accuracy and manufacturing speed is expected to replace the existing entry-level 3D printer.
