A Novel Handheld Laser Reading Device Based on OCR Recognition Technology

Abstract

The invention discloses a novel hand-held laser reading device based on OCR identification technology, which includes a hand-held reader and a mounting base; the reader includes a casing, an OCR recognition device and a laser scanning device installed in the casing, and the casing includes The head, the handle and the tail; the front end of the base has a front storage slot for accommodating the head of the housing, and the rear end is provided with a rear storage slot for accommodating the tail of the housing, and a charging plug is arranged in the rear storage slot; the OCR identification device includes an image acquisition unit, A memory, an OCR character recognition unit, a controller and a text-to-speech conversion unit. The information reading device of the present invention can recognize graphics and two-dimensional codes at the same time, and can be freely selected according to user needs; at the same time, the device also optimizes the charging system and display mode, so that users can flexibly choose the displayed information , more convenient and intelligent.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a novel hand-held laser reading device based on OCR recognition technology. Background technique [0002] At present, most places that need to verify the identity of personnel or goods generally use manual verification to confirm the identity of personnel or the type of goods, etc., which is not efficient and will also bring uncertainty to the verification results; However, the accuracy of simple portrait comparison is low, which cannot meet the current needs of relevant departments to verify the identity of the certificate holder. [0003] A code scanner is a machine that reads barcode information. It is a common information reading device. It uses an infrared light source to emit, and then uses a chip to decode according to the reflection result, and finally returns the correct value represented by the barcode. character. Barcode scanners are divided into palm-type ...

AI Technical Summary

Problems solved by technology

Mask-type laser beams have about 1-2 beams, while desktop-type laser beams are mostly laser-type, with 1-20 laser beams, which are distributed in a mesh. The more the number of beams, the faster the scanning speed, so it is like a supermarket. Most places use desktop scanners because of fast speed requirements. The scanning principle of handheld scanners is mask type: several light sources are emitted at the front end, and then the data is judged by receiving the position and size reflected by the white lines in the barcode; Laser type: The front end emits linear infrared rays, scans the barcode back and forth, and then receives the position and size of the white line reflected in the barcode to judge the data. However, the current handheld scanner has a single function and cannot meet the needs of modern people. Need more service functions to expand the use of scanners

[0004] However, the barcode scanner or information reading device in the prior art has a single function and cannot be used in various occasions, for example, it cannot be used for scanning personnel identities and goods at the same time, which affects the scope of application to a certain extent.
