Abstract

The present invention is a system for comprehensive observation and tracking of objects in distinct defined areas. This is implemented by the use of imaging sensors, comprising an electronic video camera and integrated processors, providing an overhead view of a pre determined sector during real time. The system also comprises a central processing unit (CPU) for managing all processed data, a display and managing unit which can be used for initializing, updating parameters and managing the system. The system supports means of communication between the imaging sensors and the central processing unit and between the central processing unit and the display and managing unit. The integrated processor of each of the sensors comprises 3 dimensional region of interest (3D ROI) software, which allows definition of a 3D-ROI to be imaged by each of the cameras and understanding of the spatial context of the features in the ROI, and software which allows extraction of data relevant to the identification, location and motion of objects in the ROI. The communication assembly allows transmission of the relevant data from each sensor to the central processing unit which uses it in order to enable continuous tracking of the moving objects as they pass from the field of view of one sensor into the field of view of a neighboring sensor, throughout the entire observation area. In combination with the 3D-ROI software allows clearly identifying the exact location of features of the room being observed e.g. floor, windows and doors of the room being observed, allows this understanding of the spatial context and allows the ability of the system to minimize the occurrences of false alerts (Ghosts).
