摘要
为了改善英文字母识别软件系统的性能,笔者以精准性、功能全面性为改善突破口,选取Lab Windows/CVI作为开发工具,在Linux嵌入式操作系统平台上开发一套英文字母识别软件系统。该系统利用A/D转换模块,将模拟信号信息转化为数字信号,在多功能车辆总线(Multifunction Vehicle Bus,MVB)控制下调用函数操作命令,识别图像中的英文字母。测试结果显示,本系统能够准确识别图像中的车票英文字母信息,而且识别精度在90%以上,可以作为英文字母识别辅助工具。
In order to improve the performance of English letter recognition software system, this paper takes accuracy and functional comprehensiveness as the breakthrough, and selects lab As a development tool, windows/CVI develops a set of English letter recognition software system on Linux embedded operating system platform. The system uses a/D conversion module to convert analog signal information into digital signal. Under the control of MVB bus, the system calls function operation commands to recognize English letters in the image. The test results show that the system can accurately identify the English letter information of the ticket in the image, and the recognition accuracy is more than 90%. It can be used as an auxiliary tool for English letter recognition.
