An optical method to measure the three-dimensional (3D) shape of a surface with specular reflection is proposed. The proposed method is based on the analysis of the geometric path of the light from a point source, and the relative displacements of points in the reflection image. The 3D shape of a concave mirror is shown to be determined approximately via experiments, where the vision system consists of LED array illumination, a half-mirror, and an imaging sensor.

최근 메타버스는 초대형 소셜미디어회사인 페이스북의 사명과 비전 변경으로 인해 그 어느 때보다 트랜디한 키워드로 부상되고 있다. 초기 메타버스는 지금의 가상현실(Virtual Reality)와 거의 동일한 개념으로 사용되었으나, 2007년 ASF이후 AR, VR, 미러월드, Lifelogging과 같이 다양한 영역을 통한 새로운 세계의 도출이라는 확장을 통해 그 활용 가능성이 무궁무진해지고 있다. 한편, 메타버스의 영역 확장에도 불구하고 HMD는 메타버스의 중요한 하드웨어라는 인식이 더 견고해지고 있는데, 그동안 고가였던 HMD가 2020년 보급형HMD의 등장으로 본격적인 판매량 증가를 보이고 있다. 본 연구는 메타버스의 중요 하드웨어 중 하나인 HMD(Head-Mounted Display)의 보급 정도를 기반으로 메타버스의 대중화 정도와 근미래에 대해 알아보고자 한다.

In this paper, we studied projection mapping, which is being utilized as a digital canvas beyond space and time for theme parks, mega events, and exhibition performances. Since the existing projection technology used for fixed objects has the limitation that it is difficult to map moving objects in terms of utilization, it is urgent to develop a technology that can track and map moving objects and a real-time dynamic projection mapping system based on dynamically moving objects so that it can respond to various markets such as performances, exhibitions, and theme parks. In this paper, we propose a system that can track real-time objects in real time and eliminate the delay phenomenon by developing hardware and performing high-speed image processing. Specifically, we develop a real-time object image analysis and projection focusing control unit, an integrated operating system for a real-time object tracking system, and an image processing library for projection mapping. This research is expected to have a wide range of applications in the technology-intensive industry that utilizes real-time vision machine-based detection technology, as well as in the industry where cutting-edge science and technology are converged and produced.
