Automatic tracking of moving objects video demonstration
Video description: Two camera setup was developed: megapixel fixed camera (left) is used for general overview of the protected area and for automatic image analysis. Second Pan-Tilt-Zoom moving camera (right) is used for automatic targeting at selected objects. Background modeling is performed for localization of moving objects. Object coordinates are converted into pan-tilt-zoom coordinates for moving camera, by considering a geometric transformation between ground plane, image pixels coordinates, and cameras positions in real 3D world.
The system operator can select moving object detected in the left view (red car bounded by a blue box), and PTZ camera automatically zooms it and follows its location. PTZ camera can also be quickly positioned at any point in the scene by clicking on it in left view. That solution can be extended with move PTZ cameras, and then an optimal camera for displaying particular point is automatically selected, considering obscuration by buildings, etc.
