Abstract
Disclosed herein are an apparatus and method for acquiring 3D depth information. The apparatus includes a pattern projection unit, an image acquisition unit, and an operation unit. The pattern projection unit projects light, radiated by an infrared light source, into a space in a form of a pattern. The image acquisition unit acquires an image corresponding to the pattern using at least one camera. The operation unit extracts a pattern from the image, analyzes results of the extraction, and calculates information about a 3D distance between objects existing in the space.
