Image obtaining apparatus for imaging target area

Abstract

The invention relates to an image obtaining apparatus for imaging a target area. The image obtaining apparatus comprises a first circuit board, a plate-to-plate connector, an illumination light source, an aiming light source, a communication interface, a second circuit board, a control circuit, an image sensor based on complementary metal oxide semiconductors (CMOS) and a pedestal, wherein the communication interface and the control circuit are arranged on the first circuit board, and the communication interface is in communication connection with the image sensor based on CMOS, the illumination light source, the aiming light source and the control circuit, and communicates with the external. The structures of the module are integrated to form a small and special integral module, and the entire module communicates with the external through the communication interface to realize transmission of control signals and image data. The integral module is convenient for mass production, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic identification, in particular to an image acquisition device for imaging a target area. Background technique [0002] A two-dimensional barcode is a black and white matrix area distributed on a plane (two-dimensional direction) with a specific geometric figure according to certain rules, and the matrix area is used to record symbol information. Two-dimensional codes can be divided into stacked two-dimensional codes and matrix two-dimensional codes. The stacked two-dimensional code is composed of multiple lines of short-cut one-dimensional barcodes stacked; the matrix two-dimensional barcode is composed of a matrix, and the corresponding element position of the matrix is ​​represented by a "dot" in binary "1", and a blank is used to represent a binary "0", the data code consists of dots and empty arrays. In daily life and industrial applications, bar codes are used more and more widely, such as: retail i...

AI Technical Summary

Problems solved by technology

[0004] There are many deficiencies in the existing imaging modules circulating in the market. They are large in size and use a spherical lens module, which is limited by production requirements, so that the overall volume of the product cannot be reduced; its optical performance is poor and its field of view is small, which affects its use. , the aperture is small, it needs external supplementary light, and the power consumption is large; its speed is slow, the number of CMOS frames used is low, and the reading speed is slow; its power consumption is high, and the power consumption of CMOS used is large; its life cycle is uncontrollable, and CMOS is an early stage It takes a long time to put into production, and it is easy to be eliminated and affect the subsequent production; its production efficiency is low, the lens and CMOS are first adjusted and then fixed, the requirements for the production environment are high, the error introduced manually is large, and the production efficiency is low.
