摘要

这是两篇论文中的第一篇,描述了用于光学扫描压花盲文和将扫描文本转换为二进制盲文表示的便携式原型设备。这个原型是与盲人协会(WA)共同开发的。还实现了将文字盲文代码转换为扩展文本的应用程序,并在第二部分中进行了描述。该系统利用手持扫描仪,通过线性128像素CCD阵列实时捕捉凸纹盲文图像。德州仪器数字信号处理器执行识别处理。

A portable device for optically recognizing Braille. I. Hardware development
This is the first of a pair of papers that describe a prototype portable device for optically scanning embossed Braille and conversion of the scanned text to binary Braille representation. This prototype has been developed in conjunction with the Association for the Blind (WA). An application to convert the literary Braille code to expanded text has also been implemented and is described in part II. The system developed utilises a hand held scanner that captures the embossed Braille image, in real time, via a linear 128-pixel CCD array. A Texas Instruments digital signal processor performs recognition processing.
