Title: METHOD AND CAMERA FOR THE REAL-TIME ACQUISITION OF VISUAL INFORMATION FROM THREE-DIMENSIONAL SCENES
Abstract:
The invention relates to a method for calculating the focal stack associated with an object space from the plenoptic function thereof, using a sum transform along the length of constrained planes in discrete hypercubes, enabling the calculation time to be considerably reduced. The invention also relates to a method for increasing the resolution of the focal stack obtained. In addition, the invention relates to two methods for the real-time recovery of the depths and moduli and phases of the complex amplitude of the wavefront respectively in each position of the surfaces of a three-dimensional scene and to a system designed to carry out the aforementioned methods.
