Abstract

A system and method for detection of a moving object in an image zone for possible use in the field of road and traffic safety related and/or gate monitoring systems includes an image sensor for imaging a field, a user interface for defining at least one detection zone within the field, a processor coupled to the user interface and the image sensor for detecting if a moving object has entered the at least one detection zone and an alarm providing a signal in response to detection of a moving object within the at least one detection zone.

Claims

1. A system for moving object detection comprising:

an image sensor for imaging a field;

a user interface for defining at least one detection zone within said field;

a processor coupled to said user interface and said image sensor for detecting if a moving object has entered said at least one detection zone; and

a system responsive to said processor for providing one of an alarm signal to said user or a gate actuation operation in response to detection of a moving object within said at least one detection zone.

2. The system of claim 1 capable of being mounted on a tripod for fixed traffic monitoring applications.

3. The system of claim 2 wherein said alarm signal comprises an auditory and/or visual signal.

4. The system of claim 1 capable of being mounted on a vehicle for mobile traffic monitoring applications.

5. The system of claim 4 wherein said user interface comprises a display incorporating a touch screen interface.

6. The system of claim 1 wherein at least one detection zone comprises a plurality of detection zones.

7. The system of claim 6 wherein at least one attribute may be selected by a user corresponding to each detection zone.

8. The system of claim 7 wherein said at least one attribute comprises an alarm type.

9. The system of claim 1 wherein said at least one detection zone comprises a user selectable polygon.

10. The system of claim 1 further comprising a high speed communication module coupled to said processor for communication with an external device.

11. The system of claim 1 further comprising an impact sensor coupled to said processor.

12. The system of claim 1 further comprising an interface for writing to a removable external storage device.

13. The system of claim 1 further comprising a memory coupled to said processor.

14. The system of claim 1 further comprising a plurality of general purpose input/output ports.

15. A method for moving object detection:

imaging a visual field;

defining at least one user defined detection zone within said visual field;

detecting if a moving object has entered said at least one detection zone; and

creating one of an alarm signal to said user or a gate actuation operation in response to detection of said moving object within said at least one detection zone.

16. The method of claim 15 further comprising continuously monitoring a relative size and direction of objects in said at least one detection zone.

17. The method of claim 16 further comprising setting an alarm level based on said relative size or direction of said objects.

18. The method of claim 15 further comprising continuously monitoring said at least one detection zone to determine which objects are stationary.

19. The method of claim 15 further comprising setting an object size threshold.

20. The method of claim 15 further comprising defining a plurality of detection zones.
