Method and apparatus for obtaining an image 3d

The present invention provides a method and apparatus for obtaining a 3D image. Apparatus of the present invention according to the embodiment includes a 3D image obtained emits an infrared (IR) light to the light transmitting portion configuration recognition target; comprising the light-receiving portion of the infrared and visible RGB-IR sensor reflected from the recognition target; processor, using each 3D image information to obtain depth information including the recognition target image and the visible light receiving portion receiving an infrared and visible light; controls infrared (IR) portion of the structured light illumination light cycle. Further, the present invention also includes the 3D image information processor obtains a restored image recognition target 3D image display portion, and to provide recovery in the viewable screen 3D image restoration. Methods and apparatus for obtaining a 3D image of the present invention may be adaptable in response to eliminate ambient light interference sensor RGB-IR. As a result, regardless of the image capture time or place, such as night, day, daylight or dark, a more accurate 3D images.
