Abstract

The invention provides a method for identifying a bar code, and the method is applied to data processing equipment. The method comprises the following steps: after the data processing equipment is started up, a control module loads a bar code identification program from a storage unit and then initializes the program; the control module switches the bar code identification program to a background for execution; the control module continuously monitors whether a trigger event is input into the data processing equipment, and the control module switches the bar code identification program to a foreground for execution when the trigger event occurs; when the bar code identification program is executed at the foreground, an image capture module performs image sampling, and then the control module identifies the sampled image and analyzes the message of the bar code so as to obtain an identification result; and after the control module outputs the identification result to other application programs by the mode of simulating keyboard keys, the control module switches the bar code identification program to the background for execution.

Description

technical field [0001] The present invention relates to a method for identifying barcodes, in particular to a method for identifying barcodes that simulates keyboard key output and can directly output identification results to application programs. Background technique [0002] In the prior art, there are two types of hardware for identifying barcodes. One is a specially-ordered identification device for identifying barcodes, which is connected to a terminal device. The identification device has built-in one or more barcode protocols, and performs image processing, binarization process and barcode comparison through the hardware architecture, and then sends the barcode identification results to the terminal device. The terminal device runs the matching application program, processes the result after receiving the barcode recognition result, and executes the function of the application program. The other is a data processing device with an image capture module, such as a des...
