본 논문에서는 멀티뷰 환경에서 촬영된 영상을 이용하여 카메라와 가까이 위치한 전경 물체를 중심으로 뷰가 확장된 영상을 생성하는 파노라마 알고리듬을 제안하였다. 먼저 전경 물체는 사용자가 선택한 중심 물체를 기준으로 하여 평행 이동 관계로 전경 파노라마를 생성 한다. 배경은 특징점 기반의 파노라마 기법을 이용하여 초기 결과를 얻고, 멀티뷰 영상의 시차에 기인한 가려진(occluded) 영역을 제한 영역으로 설정한 후 최적화 과정을 이용하여 시각적으로 자연스러운 배경 파노라마를 얻는다. 마지막으로 배경 파노라마와 전경 파노라마와 크기를 동일하게 하고 배경 파노라마와 전경 파노라마를 합성하여 결과 파노라마를 구성한다. 모의 실험결과 제안 알고리듬은 원본 영상의 전경 물체들을 모두 포함하면서도 배경 부분은 시각적으로 자연스러운 파노라마 결과를 도출함을 확인하였다.

This study aims to develop a 3D map which allows users to better understand the overall topography and to memorize the general concepts of the current location for tourists. The Map also utilizes different forms and color codes of the block units in the panoramic view. First, in preparation for making the road block unit, 28 types of roads presented in common map were defined. Based on the definitions, 12 dominant groups were formed. In designing each form, visual correlation was considered. Second, 42 types of terrain features presented in normal maps were defined for making the panoramic block unit. Then, 2 dominant groups, each contains 5 subgroups, were made according to the assemble pattern and the size of area. On the basis of the grouped units, the panoramic block units were produced with 3D pole line graphics maintaining integration. Lastly, each panoramic block units were categorized by color classes such as blue, green, gray and brown class. The overall color combination of the work was evaluated as well harmonized since the Moon&Spencer's Aesthetic measure value exceeds 0.5.

Panoramic image creation has been extensively studied. Existing methods use customized hardware, or apply post-processing methods to seamlessly stitch images. These result in an increase in either cost or complexity. In addition, images can only be stitched under certain conditions such as existence of characteristic points of the images. This paper proposes a low cost and easy-to-use system that produces realtime panoramic video. We use an off-the-shelf embedded platform to capture multiple images, and these are then transmitted to a server in a compressed format to be merged into a single panoramic video. Finally, we analyze the performance of the implemented system by measuring time to successfully create the panoramic image.

본 연구의 목표는 GPS(Global Positioning System)을 이용한 3차원 네비게이션 시스템을 개발하여 원하는 목적지까지의 경로를 실시간으로 도로 전경과 동일한 3차원 영상으로 살펴봄으로써 운전자를 효과적으로 도울 수 있도록 하는 것이다. 실제 도로에서 일정 간격을 두고 촬영한 파노라마 실사 영상에 TIP 기법을 적용하여 가상환경을 구축하고 이들 사이의 부드러운 전이를 통해 사진과 같은 품질의 3차원 영상을 보여준다. 개발된 시스템은 2차원 네비게이션 모듈을 가지며 최적 경로 탐색 및 도로 상황 예측 기능을 제공한다.

In this paper, we propose an algorithm for generating panoramic videos using fixed multiple cameras. We estimate a background image from each camera. Then we calculate perspective relationships between images using extracted feature points. To eliminate stitching errors due to different image depths, we process background images and foreground images separately in the overlap regions between adjacent cameras by projecting regions of foreground images selectively. The proposed algorithm can be used to enhance the efficiency and convenience of wide-area surveillance systems.

Objective of this study is to develop a 3D car navigation system that shows the driving direction to a destination through real-time 3-D panoramic views of the route. For the purpose, a new searching process was established to find the optimal driving direction based on the driver's current location and the real-time traffic situation and the TIP (tour into the picture) method was extended to implement a wide virtual environment. A virtual environment was built up by applying the extended TIP method to the panoramic images taken at a constant distance from a real road, and then, displayed 3-D navigation as clear as the real images. The car navigation system developed in this study provides the optimal driving direction and real-time traffic situation using 2-D navigation module and 3D navigation module.

Screen X is one of the Premium Large-Format platforms. Screen X projects images and video along the side wall of the theatre that go in synch with the front main screen. It's a different way of immersing the audience. This technique demands film-makers taking the two new "screens" into account when making movies. Screen X is the most obvious feature of viewing content with a range of 270 degrees. Viewers can view the experience of viewing experiences beyond the frame of screen screens by allowing viewers to experience the experience beyond the frame of screen screens, which means screen X can immerse the audiences without 3D glasses. Based on the results of this study, studies of content specifications and how they fit in the screen X are studied, and goals for maximizing the visual effects of the visual effects are studied. Looking forward to future research paper researchers and industry professionals who will benefit from future research papers.

Realistic videos using multi-view videos are created so that the contents shown on multi-view displays or screens look realistic. These images have been mostly used for special videos for exhibition, but, recently, systems such as Screen X have given rise to multi-view images as a format for storytelling contents such as movies. This study used HD-level broadcasting digital video camera with three zoom lenses for shooting wide to close-up shots focusing on a person, in the same way as Screen X, and identified and analyzed problems found during multi-view image registration correction. The results of this study suggested, provided the shooting technique and equipment are improved, the multi-view format can be used for conveying stories and information. Future research will need to investigate and supplement relevant techniques that will enable production of high-quality multi-view image contents by using a cinema-grade camera with standard lenses, instead of using broadcasting-grade zoom lenses.
