A survey of data acquisition techniques for volumetric 3D display system

Volumetric 3D display is one of the most active research areas in computer vision,it shows each single voxel in real spatial position,and therefore reconstructs a complete 3D object model in space.However,the data acquisition process for volumetric 3D display is difficult as there are still a lot of unresolved issues in scenes reconstruction,especially for real world scene modeling;also,data representation for volumetric 3D display system is different from conventional ways.This paper analyzes the characteristics of volumetric 3D display and gives a survey of its data acquisition techniques.
