Method of conversion of a hard-copy document containing text or image data into the electronic document
View Patent ↗A method of obtaining graphical information from a single- or multi-page document printed on a hard media where reading out of the position of the document elements is performed by using a method of volumetric scanning of a document (even closed) is described. Processing of scanning results, comprises joining up the separate scanning layers scanning results, removing noise, correction of document image orientation, dividing information into portions relating to separate pages, is performed after reading the information. Then text information recognition contained in the graphical file is performed. Information may be read out by using methods of magnetic resonance scanning, supersonic scanning, X-ray scanning etc. The results of scanning in electronic form may be stored for further transmission thereof on a medium or via communication channels to a distant location for recognition.
1. A method of converting a hard-copy document into electronic form via scanning, the method being performed by a scanner, the method comprising:
performing a volumetric scan of the hard-copy document comprising:
performing radiation treatment of the hard-copy document with a at least one of a printed, volumetric-formed, and embossed text;
receiving signals as a result of the radiation treatment;
combining the received signals;
rendering an electronic document based on the combining of the received signals; and
sending the electronic document to at least one of a character and text recognition, wherein performing radiation treatment comprises use of radiation of different reflecting or refracting ability based on at least one of a medium matter, volumetric-formed letters matter and matter of any printed letters thereon, and said volumetric scan is performed on a layer by layer basis.
2. The method as recited in claim 1 , where combining the received signals is performed via consolidation of signals obtained from scanning of layers.
3. The method as recited in claims 1 , where said rendering the electronic document, further comprising removing noise; document image orientation adjustment if necessary; division of electronic document information into parts relating to single pages of the initial document.
4. The method as recited in claim 1 , where said volumetric scanning is performed at the resolution sufficient for reliable distinguishing of information signs on said medium and said single layers are assigned to be not thicker then the single medium sheet being scanned.
5. The method as recited in claim 1 , where the data scanning is performed with the use of nuclear-magnetic resonance means.
6. The method as recited in claim 1 , where the data scanning is performed with the use of ultra sonic means.
7. The method as recited in claim 1 where the scanning is performed with the use of X-ray means.
8. The method as recited in claim 3 , where the electronic document is stored in memory and further transmitted distantly for recognition to a geographically different place.
