Abstract
This invention provides an object tracing apparatus that traces an object in a video obtained by an image capturing apparatus, comprising a tracking unit that tracks the object in a frame in the video and obtains track data indicating consecutive appearances of the object, and a tracing unit that generates trace information indicating which object ID each track ID belongs to, by associating a track ID obtained via tracking by the tracking unit with an object ID for uniquely identifying an object, wherein the tracing unit, on a basis of a coexistence possibility relating to imaging time between a track ID associated with one or more existing object IDs and target track data without an associated object ID, determines which object ID the target track data belongs to.
