摘要
光场技术在三维重建上有着无可比拟的优势,通过采集光线的方向和强度,借助渲染计算就能在虚拟世界还原现实场景.这一技术的发展为博物馆创建虚拟漫游系统提供了更加先进的助力.以上海博物馆的"大英博物馆百物展:浓缩的世界史"特展为例,试图打破时间和空间的限制,通过采集展厅各部分的光场数据打造"永不落幕"的在线展览,给观众以身临其境的参观体验,并为建设数字博物馆带来新的创意.
The light field technology has the incomparable advantage in 3D reconstruction.By collecting the direction and intensity of light,the real scene can be rebuilt in digital world with the rendering algorithm.The development of this technology has provided a lot of help for the implementation of virtual roaming system in museums.Take the special exhibition"A History of the World in 100 Objects"in Shanghai Museum as an example,the everlasting online exhibition will be built by collecting the light field data from every part of the exhibition hall.It gives the visitors a total immersion visiting experience without the limitation of time or space.And it also provides new ideas for the digital museums.
