• Object Tracking Using a Pan-Tilt-Zoom
    Camera and a Static Camera

1. Motivation

  • Static Camera
    • Possible to simultaneously watch a wide area using only one camera.
    • Difficult to watch an object with a high resolution.
  • Pan-Tilt-Zoom Camera
    • Possible to watch a wide area ysing only one camera.
    • Possible to continuously watch an object with a high resolution.
    • Difficult to simultaneously watch a wide area.

2. System Configuration

  • Cooperation of a pan-tilt-zoom camera and a static camera
    • Static Camera
      : Simultaneously watches a wide area. (low resolution)
    • Pan-Tilt-Zoom Camera
      : Continuously tracks a specific object. (High resolution)

3. Research Topics

  • Moving Object Detection and Selection
    • Background modeling & compensation, Event detection.
  • Occlusion-Robust Object Tracking
    • Robust to occlusion by static and moving objects.
  • Environment-Robust Object Tracking
    • Robust to illumination change, shadow, trees, etc.
  • Camera calibration
    • Pan-tilt-zoom & static camera parameters.
    • Two camera relationship.
  • Pan-Tilt-Zoom Control
    • Smooth camera movement.
