A database of reflected irradiance field with depth for image based relighting

摘要

Image based relighting is an important application for light field, which represents the reflectance properties of the captured object/scene. Many systems were proposed without depth information of the captured object/scene. In this paper, we propose a lighting system named as Light Cube, and the system can capture color and depth information synchronously. This is important to consequent relighting process for both image based or model based methods. Utilizing the proposed lighting system, we calibrate the illumination and reflectance performance, and capture a database for reflected irradiance field.
