Embodiment 1

[0081] During the QR code reading process, the mobile phone user opens the reading software, the camera starts to collect images, and the reading software automatically starts the reading process.

[0082] When the reading software does not find the three Finder Patterns of the QR code, a red LED light symbol is displayed on the interface of the reading software, indicating that "the signal is too weak to detect the existence of the QR code". Users can adjust the phone in a relatively large range.

[0083]When the reading software finds three Finder Patterns, but cannot correctly interpret the further Alignment Pattern, Version Information, Format Information, Timing Pattern, or cannot complete the error correction process correctly, a yellow LED light will be displayed on the reading software interface The symbol means that "the existence of the QR code has been detected, but the signal-to-noise ratio is low, and all the data can be read correctly only by fine-tuning the atti...

Embodiment 2

[0087] During the QR code reading process, the mobile phone user starts the reading software, the camera starts to collect images, and the reading software automatically starts the reading process.

[0088] When the reading software does not find the three Finder Patterns of the QR code, a red LED light symbol is displayed on the interface of the reading software, indicating that "the signal is too weak to detect the existence of the QR code".

[0089] When the reading software finds three Finder Patterns, but cannot correctly interpret the further Alignment Pattern, Version Information, Format Information, and Timing Pattern, or cannot complete the error correction process correctly, a flashing symbol will be displayed on the reading software interface, It means that "the existence of the QR code has been detected, but the signal-to-noise ratio is low, and all the data can be read correctly only by fine-tuning the attitude and distance of the reading device."

Embodiment 3

[0093] During the QR code reading process, the mobile phone user starts the reading software, the camera starts to collect images, and the reading software automatically starts the reading process.

[0094] When the reading software fails to find the three Finder Patterns of the QR code, the reading device gives the user a long beep sound, indicating that "the signal is too weak to detect the existence of the QR code".

[0095] When the reading software finds three Finder Patterns, but cannot correctly interpret the further Alignment Pattern, Version Information, Format Information, Timing Pattern, or cannot complete the error correction process correctly, the reading device will emit a rapid beep, indicating that "The existence of the QR code has been detected, but the signal-to-noise ratio is low, and all the data can be read correctly only by fine-tuning the attitude and distance of the reading device."

[0096] When the reading software stays in the "quick beep" state for ...

Abstract

A fetching method of an automatic symbol image includes carrying out computer treatment on current frame of image, judging whether image search pattern is existed in current frame of image or not and feeding back the first information to fetch next frame of image continuously if it is not or otherwise carrying out positioning and data sampling-calculation on said automatic symbol as well as carrying out decoding and error correcting on sampled data, outputting decoded data result and ending said feeding process if carried out steps are successful or otherwise feeding back the second information according to information obtained in fetching process and fetching next frame of image continuously.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to an automatic symbol image recognition method and device. Background technique [0002] With the rapid development of information technology, people have invented artificial graphic symbols to carry and transmit data. However, since the original data is coded and stored in the form of graphic symbols, when the original data is obtained through the artificial graphic symbols, the correct original data can only be obtained after accurate reading and decoding by a computing device. [0003] There are generally two situations for reading automatic symbols, one is that the relative position between the artificial graphic symbol and the reading device is fixed; the other is that the relative position between the two is not fixed (for example, reading a two-dimensional code through a mobile phone ). For the second case, the prior art generally adopts the following three methods to real...
