Abstract

Official abstract text for this publication.

An apparatus for obtaining 3D content is provided. The apparatus comprises: a lighting unit for outputting a lighting pattern having coordinate information; a depth sensor for receiving a returning beam output from the lighting unit and reflected from an object; a 2D image capturing unit for obtaining a second-dimensional image; a data processor for calculating the depth of each region using the distribution of characteristics represented on an image obtained by the depth sensor, and processing the 2D image data obtained by the 2D image capturing unit and the calculated depth data and encoding the same according to a predetermined format; and a controller for controlling the lighting unit, the 2D image capturing unit, and the data processor. The lighting unit comprises a light source and an optical element comprising a plurality of sub-grid regions for modulating beams coming from the light source.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for recognizing the distance of an object, the apparatus comprising: a lighting unit comprising one or more light sources and one or more optical elements, and for outputting a beam having at least two different focal positions; a beam receiving unit comprising an image sensor, and for receiving a returning beam reflected or scattered from the object; and an image processor for detecting the distance to the object from an image obtained by t…
