The management and quality analysis of the primitive images have been analyzed and studied in this paper, of which the content and structure are as follows:Firstly, the developing background and the meaning of the management and quality analysis of the primitive image, as well as the trends of the management and data quality of the image database studied both in and out of our country, have been discussed in detail.Secondly, the developing direction of the technology of the remote sensing image and the importance of the remote sensing images in the field of economy nowadays have been analyzed systematically. And it is pointed that the primitive image with the elements of interior and exterior orientation will become more and more important as a sort of image production.Thirdly, the hierarchical structure of database, especially the SQL Server adopted in this system, has been deep studied and analyzed in the aspects of Applying Program Interface, Internet Data Connector and ActiveX Data Object.Fourthly, the methods of assessing the quality of the remote sensing image have been put forward in the terms of geometry, construction and the integrality of the assistant information.Fifthly, the model of propagation of errors of the precision of the ground coordinates has been calculated in the steps of inner orientation, spatial resection and answering based on the deep analysis of the principles and processes of inner direction and space resection, which have also been experimented and analyzed in term of numerical value.Finally, the total design and the idiographic realization of the sub-modules have been introduced in detail, based on which the design and development of this system are realized in combination with the program languages such as VB6.0, VC6.0 and SQL.

本文针对原始影像的管理与质量分析进行了深入的研究与探讨，主要内容包括：(1)首先对原始影像管理与质量分析系统的研制背景和意义进行了详细论述，并对影像数据库管理和数据质量研究的国内外动态作了介绍；(2)对遥感影像技术目前的发展趋势以及遥感影像在国民经济生活中的地位进行了深入的分析，并指出附带有内外方位元素的原始影像作为一种影像产品将越来越会引起人们的重视；(3)对数据库的体系结构进行了深入的研究与分析，尤其是对SQL Server数据库的体系结构，从编程接口、Internet数据连接器和ActiveX数据对象三个方面进行了深入剖析；(4)从几何质量、构像质量和附属信息的完整性三个方面提出了对遥感影像质量的评定方法；(5)基于对内定向和空间后方交会原理及过程的深入分析，推导出了从内定向到空间后方交会再到最终求解地面坐标的误差传递模型，并对上述模型进行了数值实验和分析；(6)对原始影像管理与质量分析系统的总体设计和各模块功能的具体实现进行了详细的介绍，并在此基础上联合VB6.0、VC6.0和SQL等编程语言，实现了系统的设计与开发。

It settles the problems of fast video clip retrieval in large amount video database with effective organization of video features database by VA-File and fast query algorithms by restricted sliding window. In addition, we design a new similarity measure which synthetically considers the visual similarity and temporal order between video clips.

在基于低层特征的视频检索方面，本文提出了基于高维索引结构的快速视频检索算法，该方法利用高维索引结构VA-File组织视频数据库，设计了两种不同的子片段分割算法，以及新的包含视觉相似性和时序关系的视频片段相似度度量，并通过基于限定性滑动窗口的快速查询算法，在一定程度上解决了大规模视频数据库的快速高效查询问题。
