Rotating and zooming cameras, also called PTZ (Pan-Tilt-Zoom) cameras, are widely used
in modern surveillance systems. While their zooming ability allows acquiring detailed …

Calibrating narrow field of view soccer cameras is challenging because there are very few
field markings in the image. Unlike previous solutions, we propose a two-point method …

This paper surveys zoom-lens calibration approaches, such as pattern-based calibration,
self-calibration, and hybrid (or semiautomatic) calibration. We describe the characteristics …

Linear perspective cues deriving from regularities of the built environment can be used to
recalibrate both intrinsic and extrinsic camera parameters online, but these estimates can be …

Existing galvanometer-based laser-scanning systems are challenging to apply in multi-scale
3D reconstruction because of the difficulty in achieving a balance between a high …

This paper presents a novel concept of real-time catadioptric stereo tracking using a single
ultrafast mirror-drive pan-tilt active vision system that can simultaneously switch between …

This paper considers the detection of players in team sport scenes observed with a still or
motion-compensated camera. Background-subtracted foreground masks provide easy-to …

Steerable cameras that can be controlled via a network, to retrieve telemetries of interest
have become popular. In this paper, we develop a framework called AcTrak, to automate a …

Nowadays, binocular stereo vision (BSV) is extensively used in real-time 3D reconstruction,
which requires cameras to quickly implement self-calibration. At present, the camera …

With desired functionality of moving object tracking, wireless pan-tilt cameras are able to
play critical roles in a growing diversity of surveillance environments. However, today's pan …
