PTZ camera network reconfiguration

2009 Third ACM/IEEE International Conference on Distributed Smart Cameras (ICDSC), 2009
Vision Network based surveillance systems are more and more common in public places. Typically, a mixture of static and Pan-Tilt-Zoom (PTZ) cameras is used. Modern systems task PTZ cameras as a consequence of particular events needing further investigation; anyhow, the configuration of the network can be considered fixed and determined at the moment of

Refining PTZ camera calibration

2008 19th International Conference on Pattern Recognition, 2008
Due to the increased need for security and surveillance, PTZ cameras are now being widely used in many domains. Therefore, it is very important for the applications like video mosaic generation or automatic surveillance that these camera be accurately calibrated. In this paper, we address the problem of parameter refinement for such pan-tilt-zoom (PTZ)

Event recognition with PTZ cameras

3rd International Conference on Imaging for Crime Detection and Prevention (ICDP 2009), 2009
In this paper, a framework for explicit complex event recognition is proposed. The system extracts relevant features from video streams coming from PTZ cameras in order to detect, classify, and track moving objects in the scene. This information is then processed in order to recognize both simple events (instantaneous events involving a single object ...

Self-Recalibration of PTZ Cameras

2010 International Conference on Machine Vision and Human-machine Interface, 2010
Pan-tilt-zoom (PTZ) cameras have been widely used for providing flexible view selection and a wider observation range. In order to utilize these cameras for a meaning application, it is necessary to calibrate cameras. However, with camera pan, tilt and zoom, the previous calibrated camera parameters often vary, which are required to be updated ...

Panoramic Background Image Generation for PTZ Cameras

IEEE Transactions on Image Processing, 2019
Being able to cover a wide range of views, pan-tilt-zoom (PTZ) cameras have been widely deployed in visual surveillance systems. To achieve a global-view perception of a surveillance scene, it is necessary to generate its panoramic background image, which can be used for the subsequent applications such as road segmentation, active tracking, and so on.
