VERFAHREN ZUR DREIDIMENSIONALEN IDENTIFIZIERUNG VON OBJEKTEN |
摘要 |
Known security systems detecting and verifying, for instance characteristics of the face to grant access authorization, are based on evaluation of two-dimensional gray images. Additional detection and evaluation of the three-dimensional shape of the face decisively improves identification reliability. Coded illumination using a digital micromirror array is carried out in different colors and the topography of the face is determined by means of color image processing in order to pick up information in a short time period without substantially increasing the cost of the identification system. |
