摘要

我们介绍了一种创新的方法来表示单个运动物体的轨迹和多个运动物体之间的相对时空关系。该表示支持一组丰富的空间拓扑和方向关系。它还支持对移动对象的定量和定性用户查询。为方便查询处理，设计了运动物体轨迹匹配和时空关系匹配算法。这些算法可以处理精确匹配和相似匹配。我们还讨论了基于视频模型的运动对象模型在面向对象系统中的集成。

Modeling of moving objects in a video database

We introduce an innovative way to represent the trajectory of a single moving object and the relative spatio-temporal relations between multiple moving objects. The representation supports a rich set of spatial topological and directional relations. It also supports both quantitative and qualitative user queries about moving objects. Algorithms for matching trajectories and spatio-temporal relations of moving objects are designed to facilitate query processing. These algorithms can handle both exact and similarity matches. We also discuss the integration of our moving object model, based on a video model, in an object oriented system.
