Universal character recognition system applied to the detection of telephone recharge cards

Introduction to Universal Character Recognition System

The universal character recognition system is used to identify and verify character type identifiers on various types of products. The system integrates an efficient image processing algorithm module, a PC-side visual control interface, and a DSP-side high-performance processing platform. It can quickly and flexibly customize and develop a complete set of solutions (software + hardware + algorithms) for different areas. Can be easily applied to many types of production process.

The system is mainly composed of three parts, namely: universal character recognition algorithm module, universal character recognition software and smart camera. The system uses the universal character recognition software on the PC to remotely control the smart camera via Ethernet to perform character recognition and verification.

The system has the following basic functions:

̈ Network configuration: automatic search server, dynamically modify network settings (optional)
̈ Secure Login: Login Authentication, Single User Access (optional)
图像 Image acquisition: single frame and continuous acquisition, can be saved as BMP image ̈ Remote control: Ethernet access interface, modify system parameters in real time ̈ Data storage: save log information and processing results (optional)
通用 General font: On-site recognition font generation (optional)
自主 Autonomous operation: IO trigger, image trigger (optional)
̈ Digital I/O: Custom multi-channel I/O signal input/output (optional)
升级 Upgrade function: customized development for users, remote upgrade support (optional)
工程 Project Management: Supports job site save and restore ̈ Multiple ROIs: Support multiple ROIs running at the same time, and provide position correction function (optional)

System performance indicators:

训练 It is easy to train and recognize characters, and it can automatically segment and recognize characters in the ROI.

̈ Support setting multiple character recognition areas, and set pre-known character strings, I/O ports and other information for each recognition area;

具有 Has self-learning function, does not restrict character type fonts, and supports the recognition of oblique characters;

̈ Support users to create and manage a common character library;

允许 Allows the user to save multiple sets of character processing information and processing results in the form of a project.

̈ Support alarm signal when detecting error, and display error details on PC screen;

̈ It can conveniently monitor, remotely configure and debug the system through PC-side universal character recognition software.

Smart camera performance indicators:

̈ 1.3 million pixels, up to 18fps at the highest resolution

̈ 1/2" CMOS Image Sensor

相机 Camera parameters can be configured in real time

̈ Windows installation, Chinese interface, easy operation

完成 Tasks can be completed without professional lenses and special lighting

体积 Small size and light weight

Application in Printing Test of Phone Recharging Card

The universal character recognition system is applied to a telephone recharge card production line for detecting the quality and order of passwords sprayed on a recharge card. If a quality problem or a wrong sorting is found, the system will prompt an error message to facilitate culling or other special handling.

1. Detected phone recharge card

2. Introduction to the main interface of the system software

There are four views in the View area of ​​the main interface. You can switch the view area to the desired view by selecting View/Configuration View, View/Character View, View/Font View, or View/Result View in the menu bar.

3. The test result is used to identify the card number image, see below:

[A]: Good quality character

Original image:

Segmentation result:

Recognition result:

[C]: Problem detected by the test 2: The number is blocked:

Test results:

It can be seen from the above recognition results that the Hanwang universal character recognition system has the characteristics of rapid detection, high accuracy, and continuous detection over a long period of time. It can be widely used in various cards, packaging, printing, food, beverages, pharmaceuticals, tobacco , wine, electronics and other production areas.
