Examples
- In the first part of this thesis , the method of data collection for building a 3d scene based on a planar vector map is studied . to the most difficult problem in data collection : the evaluation of contour line , a suit of effective automatic assisting method is advanced , which can remarkably shorten the process period and improve the efficiency of spatial data collection . the main idea of this method is " control point congregating automatically and close control point cooperating "
本文主要研究了基于二维矢量图如何获取构建三维场景所需的空间数据，包括地形、地物的二维数据采集与三维建模方法，并针对数据获取中的主要难题，即等高线高程赋值问题，提出了一种基于高程控制点自动聚集、相近控制点协作的自动处理方法，显著缩短空间数据获取的处理周期。 - This paper in turn introduces correlative knowledge on case description and a object oriented representation , the aim , tenet of casebase organizing and index and a organizing and index method using dynamic clustering , several typical case retrieval methods , the acquirement of adjustment knowledge , the classification of adjustment methods and a transform adjustment model , evaluate method of new case and learning and maintenance of casebase etc . moreover this paper also stressed discusses two central problem in case retrieval : the setting of property weight and the assignment of local similar degree between property values
本文依次介绍了案例表示的相关知识及一种面向对象的表示方法，案例库组织索引的目标、原则及采用动态聚类进行组织索引的方法，几种典型的案例检索方法，案例调整知识的获取、调整方法的分类及一个转换式调整模型，新案例的评估方法及案例库的学习与维护等。此外，对于案例检索过程中的两个重要问题，属性权重的设置和属性值间局部相似度的赋值问题作了重点讨论。
