项目摘要

The purpose of this research is to develop a drawing image processor which can translate words or phrases contained in drawing images from one language to another, according to human specification of image size, line width,character font sixe, etc. Drawing images are, at first, fed from a image scanner to data flow processor. The data flow processor extracts the features such as connected regions, vertical or horizontal lines. The features are,then, transmitted from the data flow processor to a host processor. The host processor identifies the character string and extracts the connecting points. These structural data of input drawing images are transformed according to the specification. Then, an output image is generated using the transformed structural data and the input image. In this drawing image processor, segmentation and labeling of constituents and translation, transformation, editing and fair printing of drawing images are included.At 1985, we developed the first version of the drawing image processor. At the year 1986, we improved and intensified the processor to a practical level in the following points.1. Error occurs frequently in structural analysis when image quality decreases due to contact of characters to lines, or discontinuity of lines. To solve this problem, knowledge base system was constructed by injecting the knowledge concerning "line", "character", "dotted line" and "arrow".2. Graphics software was developed to increase the quality of output drawing images by using CAD techniques. Fair printing is obtained by this software.3. Subpattern recognition of chinese character in the low quality drawing is studied.

本研究的目的是开发一种绘图图像处理器，它可以根据人类对图像大小、线宽、字体大小等的要求，将绘图图像中包含的单词或短语从一种语言翻译成另一种语言。数据流处理器提取连通区域、垂直线或水平线等特征。然后，将特征从数据流处理器传输到主处理器。主处理器识别字符串并提取连接点。这些输入绘图图像的结构数据根据规范被转换。然后，使用变换后的结构数据和输入图像生成输出图像。该图形图像处理机包括部件的分割和标记以及图形图像的翻译、转换、编辑和印刷。1985年，我们开发了第一个版本的图形图像处理机。1986年，我们在以下几个方面将处理器改进和强化到了实用的水平。在结构分析中，当字符与线接触或线不连续导致图像质量下降时，经常会出现错误。为解决这一问题，通过注入“线”、“字”、“虚线”和“箭头”等知识，构建了知识库系统。利用CAD技术开发了图形软件，以提高图形输出图像的质量。该软件打印效果较好。研究了低质量图纸中汉字的子模式识别问题。
