METHOD AND CAMERA FOR THE REAL-TIME ACQUISITION OF VISUAL INFORMATION FROM THREE-DIMENSIONAL SCENES

摘要

The invention relates to a method tor calculating the focal stackassociated with an object space from the plenoptic function thereof,using a sum transform along the length of constrained planes indiscrete hypercubes, which allows the computing time to beconsiderably reduced. The invention also relates to a method forincreasing the resolution of the focal stack obtained. In addition,the invention relates to two methods for the real-time recovery of thedepths and moduli and phases of the complex amplitude of the wavefrontrespectively in each position of the surfaces of a three-dimensionalscene and to a system adapted for carrying out the aforementionedmethods.
