Heterogeneous spatio-temporal trajectory adjoint relationship identification method and system

The invention discloses a heterogeneous spatio-temporal trajectory adjoint relationship identification method and system, which are used for improving the recall rate of adjoint relationship identification and accurately identifying adjoint relationships among heterogeneous spatio-temporal trajectories. The heterogeneous spatio-temporal trajectory adjoint relationship identification method comprises the following steps: acquiring heterogeneous data, and creating a corresponding heterogeneous spatio-temporal trajectory table; determining accompanying tasks, performing space-time collision and similarity evaluation on tracks in the track table corresponding to the accompanying tasks, and generating an accompanying result candidate set according to an evaluation result; and on the basis of the adjoint result candidate set, carrying out heterogeneous spatial-temporal trajectory adjoint relationship identification tasks in different application scenes. 本发明公开了一种异构时空轨迹伴随关系识别方法及系统，用于提高伴随关系识别的召回率，以及准确识别异构时空轨迹间的伴随关系。本申
