ABSTRACT:
An object monitoring system includes a camera node (2) for monitoring movement of an object (18) to determine an acquisition time when an image of the object (18) is to be acquired and acquiring the image at the predetermined time. The system includes a camera (6) which is able to monitor moving objects (18), and image processing circuitry (10), responsive to the camera (6), which is able to detect a predetermined moving object (18) from other moving and static objects. From the image acquired, information identifying the object (18) can be automatically extracted. The system is particularly suited to monitoring and discriminating large vehicles (18) from other vehicles over a multi-lane roadway, and acquiring high resolution images of the large vehicles (18) at a predetermined acquisition point (22). Image data acquired by a plurality of camera nodes (2) can be sent over a digital telecommunications network (45) to a central image processing system (42) which can extract vehicle identifying data, such as licence plate details, and obtain information on vehicle travel between nodes(2).
