Claims9
A system for detecting intaglio characters, comprising:
- an apparatus for recognizing intaglio characters that segments and synthesizes the intaglio characters photographed using lighting devices having different wavelengths into each wavelength;
- and
- an apparatus for detecting intaglio depths that detects widths of characters recognized by the apparatus for recognizing intaglio characters, calculates average values of the detected widths of characters, and detects the intaglio depths of characters corresponding to the calculated average values of the widths of characters based on a table in which the intaglio depths corresponding to the average values of the widths of intaglio characters are written,
- wherein each of the intaglio depths is a depth below a surface of a top surface of each of the intaglio characters.

A system for detecting intaglio characters, comprising:
- a color camera that photographs the intaglio characters using lighting devices having different wavelengths,
- wherein a system for detecting intaglio depths of characters segments and synthesizes the intaglio characters photographed by a color camera into each wavelength to recognize the intaglio characters and detects widths of the intaglio characters, calculates average values of the detected widths of characters, and detects the intaglio depths of characters corresponding to the calculated average values of the widths of characters based on a table in which the intaglio depths corresponding to the average values of the widths of intaglio characters are written,
- wherein each of the intaglio depths is a depth below a surface of a top surface of each of the intaglio characters.
