项目摘要

SORID( System for Orthodontic Image Database ) which was developed on Vax minicomputer(OS:VMS, DEC Inc.), a multimedia database system written in Fortran, has been transferred to UNIX workstation(OS: 4.3 BSD) using C language and X window system. SORID was implemented as follows:1. In the prototype, the relational database management system (RDBMS) made by ourselves was used in the system to store symbol and string data. However, from the points of view of system maintenance, we have adopted the commercial RDBMS, UNIFY instead of the band-made RDBMS. In the implementation, the file access methods in the UNIFY were utilized. The database system to manage image and line drawings data was rewritten by C.2. The system has a visual interface to retrieve the multimedia data. In the prototype, the interface was implemented by use of CORE graphic system and a universal graphic display. On the other hand, in transferring the interface X window and bitmap display were adopted. The interface has the high quality functions, data visualization, spatial and historical retrieval, browsing and image processing. The interface was programmed by C and X lib under X window system. The conversation between user and system was improved much better than that of prototype.3. The image processing system called CRIPS( craniofacial image processing system) was also transferred to create database of line drawings. The process from input of line drawings to feature extractions can be monitored under X window system. Accordingly, user can easily operate the system.

在Vax小型计算机（OS：VMS，DEC Inc.）上开发的SORID（System for Orthodontic Image Database），一个用Fortran语言编写的多媒体数据库系统，已移植到UNIX工作站（OS：4.3BSD）上，采用C语言和X窗口系统。SORID的实现如下：1.在原型系统中，采用自行研制的关系数据库管理系统（RDBMS）存储符号和字符串数据。但从系统维护的角度考虑，我们采用了商品化的关系数据库管理系统-在实现过程中，利用了XML中的文件访问方法。用C.2重写了管理图像和线条图数据的数据库系统。该系统有一个可视化的界面来检索多媒体数据。在原型中，该接口是通过使用CORE图形系统和通用图形显示来实现的。另一方面，在界面的调用上，采用了X窗口和位图显示的方式.该界面具有高质量的功能，数据可视化，空间和历史检索，浏览和图像处理。在X窗口系统下，用C语言和X库编写了人机界面.与原型相比，用户与系统之间的对话得到了很大的改善.同时调用图像处理系统CRIPS（颅面图像处理系统）建立线纹图数据库。在X窗口系统下，实现了从输入线条图到特征提取的全过程监控。因此，用户可以容易地操作系统。
