摘要

PPROBLEM TO BE SOLVED: To provide retrieval technology for retrieving moving locus data whose shape is similar to moving locus data given as a sample at high speed. PSOLUTION: The prescribed number of groups of continuous moving locus points is extracted from moving locus data. An average value of respective coordinate values of the moving locus points is calculated at every extracted group of the moving locus points, and it is plotted on space. Then, an index is generated by dividing space based on its distribution. The average value of the coordinate values of the moving locus points which moving locus data whose retrieval is requested has. Moving locus data whose difference value of the average value becomes not more than a specified value is specified based on the calculated average value and the generated index. Thus, data similar to moving locus data whose retrieval is requested is specified, and a degree of similarity between specified moving locus data and moving locus data whose retrieval is requested is evaluated. Thus, data similar to moving locus data whose retrieval is requested is retrieved from retrieved moving locus data. PCOPYRIGHT: (C)2004,JPO

要解决的问题：提供一种检索技术，以高速检索形状类似于作为样本给出的运动轨迹数据的运动轨迹数据。

解决方案：从运动轨迹数据中提取指定数量的连续运动轨迹点组。在每个提取的运动轨迹点组处计算运动轨迹点的各个坐标值的平均值，并将其绘制在空间上。然后，通过基于其分布划分空间来生成索引。要求检索的运动轨迹数据具有的运动轨迹的坐标值的平均值。基于计算出的平均值和所生成的指标，确定平均值的差值变为规定值以下的移动轨迹数据。因此，指定与被请求检索的运动轨迹数据相似的数据，并且评估所指定的运动轨迹数据和被请求检索的运动轨迹数据之间的相似度。因此，从检索到的运动轨迹数据中检索与请求检索的运动轨迹数据类似的数据。
