Abstract: Provided are an object tracking system and an object tracking method. The object tracking system includes: a terminal identifier and reference time providing module configured to receive an identifier of a terminal and a reference time for tracking an object corresponding to the identifier; a cross-CCTV detection module configured to detect a cross-CCTV for the terminal by using a CCTV installation information and a location of the terminal before the reference time; a basic image detection module configured to detect an object repeatedly appearing in the cross-CCTV as a basic image; a current-CCTV detection module configured to detect a current-CCTV currently recording the terminal by detecting a location and a moving direction of the terminal after the reference time; an object detection module configured to detect an object appearing in the current-CCTV based on the location and the moving direction of the terminal after the reference time; and an object tracking module configured to track an object corresponding to the identifier by determining whether the detected object from the current-CCTV and the basic image.
