Movement line information generation system, movement line information generation method and movement line information generation program

A trajectory display method comprising:

• capturing, by a camera images of moving bodies in a tracking region,
• inputting trajectories of the moving bodies in the tracking region of the images;
• generating a score for each moving body trajectory included in the tracking region of the image, each score indicating a likelihood that the respective moving body trajectories included in the tracking region of the images correspond to identification information of at least one object;
• and
• determining an area of the tracking region of the images having a high density of the moving bodies, the high density of the moving bodies in the area being of a predetermined value or higher;
• associating, based on the scores, a set of the moving bodies in the tracking region of the images and a set of the identification information;
• and
• controlling a display to display, for the area having the high density of the moving bodies, trajectories of the set of the moving bodies in the tracking region of the images, present in the area having the high density of moving bodies, and pieces of information of the set of the identification information which may correspond thereto, in association with the scores, on a map.

A non-transitory recording medium storing instructions, the instructions causing a computer to perform:

• controlling a camera to capture images of moving bodies in a tracking region;
• inputting trajectories of the moving bodies in the tracking region of the images;
• generating a score for each moving body trajectory included in the tracking region of the image, each score indicating a likelihood that the respective moving body trajectories included in the tracking region of the images correspond to identification information of at least one object;
• and
• determining an area of the tracking region of the images having a high density of the moving bodies, the high density of the moving bodies in the area being of a predetermined value or higher;
• associating, based on the scores, a set of the moving bodies in the tracking region of the images and a set of the identification information;
• and
• controlling a display to display, for the area having the high density of the moving bodies, trajectories of the set of the moving bodies in the tracking region of the images, present in the area having the high density of the moving bodies, and pieces of information of the set of the identification information which may correspond thereto, in association with the scores, on a map.
