Practical pure pan and pure tilt camera calibration
Often the deployed pan-tilt-zoom (PTZ) cameras undergo a pure pan or pure tilt rotation. This is a degenerate case for most of the PTZ camera calibration methods. That is, under t...

Camera Calibration from the Quasi-affine Invariance of Two Parallel Circles
Abstract. In this paper, a new camera calibration algorithm is proposed, which is from the quasi-affine invariance of two parallel circles. Two parallel circles here mean two circl...

Snapshot: A Self-Calibration Protocol for Camera Sensor Networks
— A camera sensor network is a wireless network of cameras that are designed for ad-hoc deployment. The camera sensors in such a network need to be properly calibrated by determi...

Self-Calibrating Depth from Refraction
In this paper, we introduce a novel method for depth acquisition based on refraction of light. A scene is captured twice by a fixed perspective camera, with the first image capt...

PTZ camera network calibration from moving people in sports broadcasts
In sports broadcasts, networks consisting of pan-tiltzoom (PTZ) cameras usually exhibit very wide baselines, making standard matching techniques for camera calibration very hard t...
