Dual aperture 3d camera and method using differing aperture areas

Abstract

A camera () for recording at least one image of at least one object () is proposed. The camera () comprises: —at least one converging element (), wherein the converging element () is adapted to converge a light beam () passing through the converging element () to travel along a beam path to be received by at least one optical sensor (); —at least one first aperture element () having a first adjustable area (), wherein the first aperture element () is located in the beam path between the converging element () and the optical sensor (); —at least one second aperture element () having a second adjustable area (), wherein the second aperture element () is located in the beam path between the first aperture element () and the optical sensor (); —the at least one optical sensor () being adapted for receiving the light beam (), wherein the optical sensor () is further adapted to generate at least one first picture in a first setting comprising the first aperture area () exceeding the second aperture area () and to generate at least one second picture in a second setting comprising the second aperture area () exceeding the first aperture area (); and —at least one evaluation device () designed to generate at least one three-dimensional image of the at least one object () by comparing the at least one first picture and the at least one second picture. Thereby, a simple and, still, efficient three-dimensional camera () for an accurate recording of an image of at least one object () in space is provided.
