一种实体运动模式相似性度量方法的研究

A Mehtod for Measuring Object Movement Pattern Similarity

运动模式相似性度量在实际工作有广泛应用。提出了一种利用序列分析手段来实现实体运动模式相似性度量的算法。序列分析方法用于提取序列各种特征,然后利用上述特征分别对运动序列中的位置序列、速度序列、方向序列进行相似性度量,再将度量综合起来作为最终的运动模式相似性度量方法。最后,仿真研究表明,算法可以比较有效度量各种运动模式之间的相似性,从而可以应用于各项需要进行运动模式相似性度量的工作。

Similarity measurement of movement pattern is widely used in practical work. By using sequence analysis methods, an arithmetic which is used to measure the similarity of the movement pattern of an object is proposed in this paper. Sequence analysis method is used to acquire various characteristics of a sequence, and then, these characteristics are used respectively to measure the similarity of position sequence, velocity sequence and direction sequence of object movement sequence. These measurements are synthesized to be the final similarity measurement of movement pattern. Finally, research data show that this arithmetic is able to measure the similarity of different movement pattern well, so it can be applied to all kinds of works which need similarity measurement of movement pattern.
