Abstract: An apparatus for obtaining a 3D image including a light transmitter configured to transmit infrared ray (IR) structured light to a recognized object; an RGB-IR sensor configured to receive infrared rays and visible light reflected from the recognized object; a processor configured to obtain 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 RGB-IR sensor. The processor is further configured to obtain infrared differential images by subtracting infrared images obtained for a visible light measurement time period T1 from infrared images obtained for an infrared measurement time period T2.

Abstract: The present invention relates to an RGB-IR sensor, and a method and an apparatus for obtaining a 3D image by using the same. The RGB-IR sensor according to the present invention comprises: a first pixel basic unit including one of each of R, G, B and IR pixels; and a second pixel basic unit in which the R, G, B and IR pixels are arranged in a different order from those in the first pixel basic unit, wherein the RGB-IR sensor is comprised by alternately arranging the first pixel basic unit and the second pixel basic unit in a horizontal direction, and wherein R, G, B and IR pixel arrangements in the first pixel basic unit and the second pixel basic unit are determined so that the position of IR-pixels in the RGB-IR sensor are not equidistance apart from each other.
