摘要
以手写数据作为数据采集对象,在远程管理系统应用中是一种新的尝试。本文设计了一种企业产品远程管理系统。在该系统中,将手写输入和网络功能嵌入工业产品中,在产品端实现用触摸屏进行手写数据输入,手写数据以汉字点阵形式通过拨号网关传送给远端企业网服务器,然后在服务器端使用汉字识别软件实现文字脱机识别。
文中详细介绍了数据采集终端的硬件设计,阐述了8位单片机系统中手写汉字点阵模型的建立、版式处理、汉字点阵的压缩算法,服务器端汉字点阵预处理方法,笔划特征的提取,小字库量汉字字模的建立形式,并提出了一种基于点阵形式的手写汉字辨识方法。在小量汉字字库的测试中,该系统满足设计需求。
This paper proposes a new method on remote data collection system which embeds the handwritten Chinese character input in the terminal product and handwritten Chinese character recognition software in the server on the other side of the internet.
The Chinese characters are input via the touchpad and converted into digital data signals. The data is collected and compressed by the single chip computer system and transferred to the server of the data process center via internet.
In the server, a handwritten Chinese character recognition algorithm using Chinese character feature extraction method is proposed. In order to recognize the handwritten Chinese character, a new model database of the Chinese character is setup. When testing with a small Chinese character database, the result meets the requirement.
