Calibrating pan-tilt cameras in wide-area surveillance networks
Pan-tilt cameras are often used as components of wide-area surveillance systems. It is necessary to calibrate these cameras in relation to one another in order to obtain a consistent representation of the entire space. Existing methods for calibrating pan-tilt cameras have assumed an idealized model of camera mechanics. In addition, most methods have been calibrated using only a small range of ...
متن کامل3D Surveillance System Using Multiple Cameras
We propose a 3D surveillance system using multiple cameras surrounding the scene. Our application is concerned with identifying humans in the scene and then identifying their postures. Such information can help with automatic threat assessment of a scene. The cameras are fully calibrated and assumed to remain fixed in their positions. Object detection and interpretation are performed completely...
متن کاملLarge Area Video Surveillance System with Handoff Scheme among Multiple Cameras
Conventional video surveillance systems often have several shortcomings. First, object detection can’t be accurate under the illumination variation environment or clustering background. Second, some dynamic textures e.g., moving leaves, clouds, can reduce the reliability of object detection. Third, when an object is tracked with multiple cameras, a handoff scheme is seldom considered. In this s...
متن کاملVisual Surveillance Using Less ROIs of Multiple Non-calibrated Cameras
With a large number of surveillance cameras, it is not an easy task to determine which camera should be monitored and which region of the camera images should be checked so that all the activities and/or events in a scene are examined. We present a new method to realize effective visual surveillance under an environment in which a number of noncalibrated fixed surveillance cameras are being ope...
متن کاملSurveillance of a 2D Plane Area with 3D Deployed Cameras
As the use of camera networks has expanded, camera placement to satisfy some quality assurance parameters (such as a good coverage ratio, an acceptable resolution constraints, an acceptable cost as low as possible, etc.) has become an important problem. The discrete camera deployment problem is NP-hard and many heuristic methods have been proposed to solve it, most of which make very simple ass...
