基于DSP的图像式彩票数字识别终端

Number recognition terminal of lottery ticket based on DSP

本文提出了一种基于数字信号处理器(DSP)的图像式彩票数字识别终端的实现方法。该终端以TI公司的TMS320VC5402定点DSP为核心,采用CMOS图像传感器以逐行扫描方式采集彩票图像,充分利用图像的二维信息,并应用先进的识别算法,从而实现了彩票数字的高效准确的实时处理。

In this paper we present and analyze a digital implementation methods of figure-type Lottery Number Recognition terminal based on DSP（Digital Signal Processor）. Fixed-point DSP TMS320VC5402 is used as core processor in technology. Maki and accurate real terminal. CMOS image sensors are also used to collect lottery images based on progressive-scan ng full use of two-dimensional image information and advanced recognition algorithms, an efficient -time processing scheme has been proposed for Lottery Number Recognition.
