Zusammenfassung: | The invention relates to a trajectory similarity calculation method and system, belongs to the technical field of trajectory tracking, and solves the problems of overlarge trajectory length difference and low total calculation efficiency in the comparison process of a dynamic trajectory and a static trajectory in the prior art. The method comprises the following steps: acquiring a dynamic track, segmenting the dynamic track according to a time parameter, and determining dynamic track segments; obtaining a static track, segmenting the static track according to the dynamic track segments, and determining static track segments in one-to-one correspondence with the dynamic track segments; the segmentation similarity between each dynamic track segment and the corresponding static track segment is calculated; and performing weighted calculation on the segmentation similarity to obtain the similarity of the dynamic trajectory and the static trajectory. And the calculation efficiency and the calculation precision of |
