Apparatus and method for acquiring 3D depth information |
| 摘要 |
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. |

1. An apparatus for acquiring three-dimensional (3D) depth information, the apparatus comprising:
a pattern projection unit for projecting light, radiated by an infrared light source, into a space in a form of a pattern, the pattern projection unit including:
a conversion unit for converting the light, radiated by the infrared light source, into parallel light;a pattern mask unit for converting the parallel light into the pattern, the pattern being a coded progression of primitives; andan adjustment unit for adjusting a focus of the pattern of light to focus the pattern over a set distance; an image acquisition unit for acquiring an image corresponding to the pattern using at least one camera; and an operation unit for extracting a pattern from the image, analyzing results of the extraction, and calculating information about a 3D distance between objects existing in the space. |
