US 2026/0311341 A1 · TRACKING DEVICE, TRACKING METHOD, AND RECORDING MEDIUM

Abstract

A tracking device that includes a tracking unit that extracts image frames from video data based on a time threshold value that is a reference for extracting the image frames to be collated with a verification frame that is a verification target, detects a tracking target in the image frames, and sets a collation range for the tracking target based on a space threshold value that is a reference of the collation range for the tracking target, a display information generation unit that generates display information including a tracking image in which the collation range is associated with the tracking target in the image frames and an operation image for setting the time threshold value and the space threshold value, and a threshold value update unit that updates the space threshold value and the time threshold value with values set by the user who refers to the display information.

Dependent claims

A tracking device comprising:

at least one memory storing instructions;
and
at least one processor connected to the at least one memory and configured to execute the instructions to:
control to display a graphical user interface to be displayed on a display, the graphical user interface comprising:
an image display area configured to display a monitoring image on which a predetermined range is superimposed, the predetermined range related to a monitoring target detected in an image frame, the predetermined range being set based on a first threshold that is a threshold related to space within the image frame, wherein a person in the predetermined range is the monitoring target;
and
a threshold setting area configured to display an operation element to set a second threshold, the second threshold being a reference related to detection of the monitoring target;
receive first updated information of the first threshold;
receive second updated information of the second threshold, based on an input for the operation element;
update the first threshold with the first updated information;
and
update the second threshold with the second updated information.
