METHOD OF SCANNING IMAGE OF SKIN LINES AND DEVICE TO THIS END |
摘要 |
FIELD: protection equipment. ^ SUBSTANCE: invention relates to computer engineering and can be used for biometric personal identification. In the method of scanning an image of skin lines, radiation flux is generated using at least two sources at different wavelengths, and radiation from each source is directed to a receiving surface at different angles of incidence. The device for realising the method has a radiation-transparent cylinder, which can turn about a fixed axis by an angle, which provides for complete movement of the analysed section of the skin relative the radiation flux from the radiation sources. The radiation sources and receiver are immovable with respect to the cylinder. ^ EFFECT: quality image of skin lines due to increased sensitivity to lines and reduced sensitivity to fat marks. ^ 4 cl,1 dwg |
