Abstract: Even when lacking an accurate association between the trajectory and identification of a moving body, the association between trajectory and identification of the moving body is estimated and the ambiguity quantified. An identification information association unit associates an individual trajectory link included in a trajectory link candidate with likely moving body identification information per trajectory link candidate. An association trend quantification unit quantifies a trend of the number of times when trajectory information is associated with moving body identification information per individual moving body identification information for individual trajectory information based on an association result between a trajectory link and moving body identification information. An association score calculation unit calculates an association score indicating ambiguity of an association between a trajectory indicated by trajectory information and a trajectory of a moving body identified by moving body identification information for each item of moving body identification information per trajectory information.

Abstract: At least one processor inputs trajectories of moving bodies in a tracking region. The at least one processor generates a score corresponding to each of the identification information, the score indicating a likelihood that the moving bodies corresponding to the identification information present in the area. The at least one processor determines an area with a high density of the moving bodies that a density of the moving bodies is a predetermined value or higher. The at least one processor associate, based on the score, a set of moving bodies and a set of identification information of the moving bodies. The at least one processor controls a display to display, for the area with the high density of the moving bodies, the set of moving bodies and the set of identification information in association with the score.

Abstract translation: 即使在移动体的轨迹与识别之间缺乏精确的关联的情况下，估计移动体的轨迹与识别之间的关联，并且量化量化。 识别信息关联单元将包括在轨迹链路候选中的单个轨迹链路与每个轨迹链路候选的可能的移动体识别信息相关联。 关联趋势量化单元基于轨迹链接和移动体识别信息之间的关联结果，量化轨迹信息与个体运动身体识别信息相对应的个体运动身体识别信息相关联的次数的趋势。 关联分数计算单元计算指示由轨迹信息指示的轨迹与通过每个轨迹信息的每个移动体识别信息的移动体识别信息识别的移动体的轨迹之间的关联的模糊性的关联分数。
