摘　　要：文章提出一种基于离散空间轨迹矩阵分析的重点人员伴随关系挖掘方法,针对离散空间轨迹构建人与地址的映射矩阵,通过对人员地址关系矩阵进行关联分析识别伴随关系,针对离散时空轨迹构建基于有效距离判定的伴随关系挖掘模型,通过距离、时间、空间等特征对重点人员进行伴随关系挖掘。实验结果表明,基于离散空间轨迹矩阵分析方法可以快速识别人群中存在伴随关系的人,且在给定某个重点人员的情况下,可以快速找到与之存在伴随关系的人群,并对这些人的伴随次数进行排序,便于安防人员溯源和追踪;伴随人的数量与有效距离在一定程度上成正比,伴随次数与数据量正相关。This paper proposes a method for mining key personnel adjoint relations based on discrete space trajectory matrix analysis. A mapping matrix between people and addresses is constructed for discrete space trajectories. The adjoint relations are identified through correlation analysis of the personnel address relationship matrix, and the discrete spatiotemporal trajectories are constructed. An adjoint relationship mining model based on effective distance judgments can mine the adjoint relationship of key personnel through features such as distance, time, and space. The experimental results show that the analysis method based on the discrete space trajectory matrix can quickly identify the people who have an adjoint relationship in the crowd, and given a certain key person, you can quickly find the people who have an adjoint relationship with them, and deal with these people. The number of adjoint persons is sorted, which is convenient for security personnel to trace and track in the future. In addition,the number of adjoint pairs is directly proportional to the effective distance to a certain extent,and the number of adjoint pairs is positively correlated with the increase of the amount of data.
