Abstract: The present invention provides an apparatus and a method for obtaining a 3D image. The apparatus for obtaining the 3D image, according to one embodiment of the present invention, comprises a light transmitting portion for emitting infrared ray (IR) structured light onto a recognized object; a light receiving portion comprising an RGB-IR sensor for receiving infrared rays and visible light reflected from the recognized object; a processor for obtaining 3D image information including depth information and a visible light image of the recognized object by using each of the infrared rays and the visible light, which are received by the light receiving portion; and a lighting portion for controlling a lighting cycle of the infrared ray (IR) structured light. Also, the present invention further comprises an image recovery portion for recovering a 3D image of the recognized object by using the 3D image information which is obtained by the processor, and a display portion for providing the recovered 3D image on a visual screen. The present invention, by means of the method and the apparatus, for obtaining the 3D image, can adaptively respond to the brightness of ambient light so as to eliminate interference by the RGB-IR sensor. As a result, more accurate 3D images can be obtained regardless of time or place of image capturing, such as night, day, a dark space, or a bright space.
