IMAGING SYSTEM FOR DETECTING VEHICLE AND HUMAN MOVEMENT
First Claim
1. A traffic system for alerting a driver of a motor vehicle to a traffic sign, the system comprising:
- an image sensor for capturing images;
at least one light source attached to the traffic sign; and
a control unit coupled to the sensor and the at least one light source, said control unit comprises a graphic processing unit coupled to said image sensor for processing images captured by said image sensor to detect optical flow of objects within the images so as to discriminate between vehicles and other objects, the control unit illuminating the at least one light source responsive to the detection of a vehicle.

Abstract
A traffic system for alerting a driver of a vehicle to a traffic sign includes a sensor and a control unit. The sensor may be an image sensor and the control unit may comprise a graphic processing unit (GPU) to detect the optical flow of objects in the captured images so as to distinguish moving vehicles from non-moving objects. The speed of vehicles may be detected such that the system may (1) activate lights to warn a driver if he is traveling too fast or (2) display the speed to either the driver or a police officer. The system may also be implemented and used as a geographic border monitoring system.

13. A vehicle speed monitoring system comprising:
-
at least one image sensor for capturing sequential images of approaching traffic; and
a control unit coupled to said at least one image sensor, said control unit comprises a graphic processing unit coupled to said at least one image sensor for processing images captured by said at least one image sensor to detect optical flow of objects within the images so as to discriminate between vehicles and other objects, the control unit detecting a speed of travel of each vehicle from sequential images. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A border monitoring system for monitoring activity along a geographical border, the system comprising:
at least one monitoring device each comprising;
an image sensor aimed along the border for capturing images along and in the vicinity of the border; and
a control unit coupled to said image sensor for processing the captured images and detecting moving objects in the captured images and, when a moving object is detected, causing a signal to be transmitted to a monitoring post indicating that motion has been detected. - View Dependent Claims (22, 23, 24, 25, 26)
