Real time three-dimensional display system and a method by holographic projection

摘要

A real-time color holographical three-dimension display system and method implemented by using digital holographical display theory and regular camera-projector array system are disclosed, which perform space spectrum sample taking of to-be-displayed object O on its arbitrary space spectrum surface S at a sampling density of space sample angle W mn with M*N cameras array anchored on some reference point R in the space corresponding to object O, and project each obtained space spectrum view image I mn to corresponding reference surface P R which is necessary to rebuild three-dimension information of object O using corresponding M*N projectors array at the directions that each space spectrum is taken; realize complete space spectrum output of object O through the function of the holographical function screen placed on reference surface P R of finitely widening the space spectrum of each discrete space spectrum input image information so as to achieve the holographical digital display that aims at resuming the complex wavefront.
