1.目的和方法：本研究计划旨在发展三维电脑绘图系统，以支援遗址内的发掘工作及遗址外的分析研究。通过对系统的测试，总结了系统引入对挖掘研究的影响.研究结果：三个子系统已经开发和测试的挖掘研究在阿尔图尔网站，在埃及。(1)网站系统：该系统每天在用光电测量工具完成三维测量工作后不久生成场地的平面图、剖面图和鸟瞰图图像S。很明显，系统生成的图纸和图像将有助于研究人员轻松地了解出土遗骸的空间结构。(2)实验室系统：该系统具有构建建筑元件、层和遗迹如何位于地面中的三维表面模型的实用性。这些CG模型可以用于 关于我们 从而追踪开挖过程，解剖分析各要素之间的空间关系。介绍了建筑构件照片图像数据的纹理映射技术，该技术将有助于研究人员分析构件表面的详细信息。(3)照片检索系统：它允许研究人员检索在挖掘工作期间拍摄的建筑构件和文物的照片，并且在文物分类工作之后，与挖掘现场的位置和挖掘步骤相关，通过显示的图像简单地与系统通信。该子系统还可用于现场开挖过程的跟踪.结论：如何将发掘出的遗骸记录下来，并向没有参与工作的人提供足够的数据，一直是研究人员面临的一个严重问题。这项研究表明，所开发的系统可以用来作为远有效的手段来解决这样的问题，比较二维文件，已被最终输出的传统挖掘研究。少

1. Objectives and Method: This research project aims to develop three dimensional computer graphic system to support, both excavation works of a city remains on the site, and its analytical studies at off the site. Testing the developed system in a case study, this paper reviewed an impact of system introduction to excavation studies.2. Results of Research: Three sub-systems have been developed and tested in the excavation studies at the al-Tur site, in Egypt. (1) Site System: the system generates plans, sections, and birds-eye view image s of the site, everyday, soon after three dimensional survey works with an opt-electronic survey tool are finished. It became clear that system generated drawings and images will help researchers understanding spatial configuration of excavated remains, easily.(2) Laboratory System: the system has an utility to build three dimensional surface models of how building elements, layers, and relics were located in the ground. Those CG models can be used bo … More th to trace process of excavation works, and to anatomically analyze spatial relation-ships among each element. An introduction of technique to texture map photo image data of building elements showed that it will help for researchers to analyze detailed information presented on the surfaces of those elements.(3) Photograph Retrieval System: it allows researchers retrieve photographs of building elements and relics that were taken during the excavation work, and after relics classifying works, in relation to the place of the excavation site, and to the step of excavation, simply communicating the system through displayed images. This sub-system also can be used to trace the process of excavation off the site.3. Conclusion: It has been a serious problem for researchers how to record and present enough data of remains excavated to those who did not participate in the work. This study has showed that the developed system can be used as far effective means to solve such problem, comparing to two dimensional documents that have been final output of conventional excavation studies.
