Abstract: A trajectory analysis device extracting a trajectory of movement of a moving object by using results of detection by one or more sensors disposed in an environment where the moving object exists, is provided. The device includes a storage and a controller. The storage stores: partial trajectory data indicative of a plurality of partial trajectories extracted in advance from the results of detection; connection parameter information indicative of a connection condition for connecting the partial trajectories to each other; and partial area data defining each of a plurality of partial areas. The controller connects two partial trajectories each belonging to any of the plurality of partial areas, based on the connection parameter information, to extract a trajectory of the moving object for each of the partial areas. The connection parameter information is set for each of the partial areas.

Abstract: A monitoring device (2) identifies an object from videos made by a plurality of cameras (1) including a first camera and a second camera and having a predetermined positional relationship. The monitoring device has a receiving unit (21) configured to receive the videos from the plurality of cameras, a storage unit (22b, 22c) configured to store feature information indicating a feature of the object and camera placement information indicating placement positions of the cameras, and a controller (23) configured to identify the object from the videos based on the feature information. If an object has been identifiable from the video made by the first camera but has been unidentifiable from the video made by the second camera, the controller (23) specifies, based on the camera placement information, the object in the video made by the second camera.
