Embodiment Construction

[0020] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0021] combined reference figure 1 , the present invention provides a kind of real-time targeting designated decoding method, comprising the following steps:

[0022] S1: Turn on the aiming light of the hand-held barcode scanner and turn off the light, move the hand-held barcode scanner so that the aiming point of the aiming light is aligned with the target barcode to be decoded; turn off the light, turn on the aiming light, and the aiming point of the aiming light is clearer , which is convenient for the operator to accurately project the scanning power to the inner range of the target barcode to be decoded.

[0023] S2: Trigger the handheld barcode scanner to capture the image of the barcode in real time. If the light is not turned on, the unexposed image cannot be...

Abstract

The invention provides a real-time aiming designated decoding method. A handheld code scanning gun transmits a decoding range into a decoding library to decode a bar code at a corresponding position by acquiring the central position of an aiming point in real time, and decoding data can be normally output only when the center of the aiming point is positioned in a designated bar code coordinate range, so that a function of scanning an aiming point is realized; the method is quick and convenient and has high accuracy.

Description

technical field [0001] The invention relates to a decoding device, in particular to a real-time targeting designation decoding method. Background technique [0002] Bar code technology is an automatic identification technology produced and developed in the application practice of computers. It is designed to realize automatic scanning of information, and it is an effective means to realize fast, accurate and reliable data collection. The application of barcode technology solves the bottleneck problem of data entry and data acquisition, and provides favorable technical support for logistics management. A barcode is a symbol composed of a group of regular bars and corresponding characters, which is used to represent certain information. The core content of barcode technology is to use photoelectric scanning equipment to read these barcode symbols to realize the automatic identification of the machine, and quickly and accurately enter the data into the computer for data proce...
