Preliminary Survey of Multiview Synthesis Technology

With the maturity of digital camera technology, it is feasible to form an array of cameras. The major usage of a camera array is to acquire different views of a scene in one shot. The captured data can be used to analyze the depths of the objects. Once we have the 3D model, we can synthesize virtual views, relight the scene, etc. The potential applications are virtual reality and augmented reality. In order to investigate the multiview technology, we studied the fundamental concepts, including the single lens camera, the eccentric lens camera, the plenoptic camera, and the multiview camera. We also discussed a few application examples for understanding the practical usages. The study showed that the initial depth estimation technology becomes important nowadays in providing photo realistic natural feel to people. The application areas were also extended to entertainment, and also to some crucial tasks such as medical operations and combat missions.
