Problems solved by technology

For example, a "handheld two-dimensional barcode data terminal" disclosed in the Chinese utility model patent No. 00238846.4, this data terminal will have a two-dimensional barcode reading head with hardware identification and decoding functions, an embedded computer system, a display and other components are concentrated in the hand-held housing, and its two-dimensional barcode recognition is still a hardware solution, which will make it expensive; another example is a "hand-held scanning automatic recognition browser" disclosed by the Chinese utility model patent No. 01278011.1 , this technology uses a two-dimensional barcode scanning decoder (an existing product module of American Symbol Company), that is, in this component, the reading and recognition of two-dimensional barcodes is realized in the form of hardware, because the two-dimensional barcode scanning decoder The structure is complex and the value is relatively expensive, so it affects the popularization and application of this device

Embodiment 1

[0027] Figures 1 to 3 show the specific structure of the present invention. As can be seen from Figure 1, the structure of the two-dimensional barcode reading device includes an image reading head and a computing device terminal. The two-dimensional barcode reading engine software is connected to the computing device terminal. The image reading head includes an image acquisition unit and a control board, the image acquisition unit is electrically connected to the control board, and the control board controls the image acquisition unit to complete the image acquisition function.

[0028]As can be seen from Fig. 2, the image acquisition unit includes a camera module, a laser sight, and a flash lighting unit module, and the camera module, the laser sight, and the flash lighting unit module are respectively connected to an interface controller containing a single-chip microcomputer on the control board. Connection; the positional relationship of the camera module, the laser sight ...

Embodiment 2

[0034] This embodiment is the same as Embodiment 1 except for the following features: multiple image reading heads are connected to a computing device terminal equipped with barcode reading engine software through a control interface circuit at the same time; implemented on a computing device terminal Simultaneously control the function of multiple image reading heads to read 2D barcodes.

Embodiment 3

[0036] This embodiment is the same as Embodiment 1 except for the following features: the interface communication module is a wireless interface module, and a wireless IEEE802.11X module can be selected to realize wireless communication connection.

Abstract

A kind of 2D bar reader includes image reading head, terminal of computing device. The said image reading head through control interface circuit is connected to terminal of computing device with engine software for reading and recognizing bar code being installed on. The said terminal of computing device is one of desktop computer, server, palm computer, embedded type system or handset possible to install engine software for reading and recognizing bar code. It is initiation of the invention that recognition function is transferred to terminal of computing device connected. Thus, the image reading head possesses features of simple feature, easy of manufacture, high processing capacity, good recognition effect.

Description

technical field [0001] The invention relates to a two-dimensional barcode reading technology, in particular to a two-dimensional barcode reading method and a device thereof. Background technique [0002] Since its appearance, the bar code has been widely concerned by people, and its application has developed rapidly. Its popularization and use have greatly improved the speed of data collection and information processing, improved work efficiency, and made a contribution to the advent of the information society. great contribution. Commonly used barcodes now include one-dimensional barcodes and two-dimensional barcodes. One-dimensional barcodes have been used for a long time and have a wider range, but one-dimensional barcodes have the obvious defect of less information records. Two-dimensional barcodes overcome this defect of one-dimensional barcodes. , the two-dimensional barcode was first born in the 1970s. It is a rectangular or square coding map...
