Problems solved by technology

[0002] Scanners currently on the market can only recognize ordinary paper, and have slow scanning speed and low precision, generally 200DPI and 600DPI. (red), G (green), B (blue) three light sources, can only scan and identify ordinary color and other shortcomings, so that this type of scanner can only be used for scanning and copying paper in ordinary occasions
However, for ancient books that have been affected by air oxidation, moisture, mold, and insects for a long time, the text on the books is difficult to identify; because the technology of making counterfeit banknotes and fake passports is becoming more and more sophisticated, it is difficult for ordinary people to distinguish the authenticity with the naked eye; At the crime scene, fingerprint recognition is a very important forensics technology, but usually fingerprint recognition requires professional instruments and professional operators, which greatly hinders the extraction of criminal evidence and other issues. Existing scanners cannot meet such needs

Abstract

The invention discloses an image acquisition device and a multifunctional scanner. The multifunctional scanner comprises a data acquisition part, a data processing part and a power supply part; the data acquisition part communicates with the data processing part; the power supply part supplies power to the data acquisition part and the data processing part; the scanner is rapid in scanning speed, high in acquisition pixel point precision and multiple in output spectrum, and particularly can recover fuzzy book character information; and thus, bills, passport authenticity and fingerprint identification can be distinguished rapidly and effectively.

Description

technical field [0001] The invention belongs to the application field of image scanning, in particular to a multifunctional scanner based on an image acquisition device. Background technique [0002] Scanners currently on the market can only recognize ordinary paper, and have slow scanning speed and low precision, generally 200DPI and 600DPI. (red), G (green), and B (blue) light sources can only scan and identify common colors and other shortcomings, which makes this type of scanner only suitable for scanning and copying paper in ordinary occasions. However, for ancient books that have been affected by air oxidation, moisture, mold, and insects for a long time, the text on the books is difficult to identify; because the technology of making counterfeit banknotes and fake passports is becoming more and more sophisticated, it is difficult for ordinary people to distinguish the authenticity with the naked eye; At the crime scene, fingerprint recognition is a very important for...
