Abstract

A system and method for monitoring an entity within an area is disclosed. The method includes specifying at least one criterion associated with an event of interest. The at least one criterion is specified visually on a display screen. At least one entity to be monitored is identified, and a movement of the at least one entity is captured visually on the display screen. The captured movement of the entity comprises at least one attribute associated with the at least one entity.

Claims

1. A method for monitoring an entity within an area, the method comprising:

specifying at least one criterion associated with an event of interest, the at least one criterion specified visually on a display screen;

identifying at least one entity to be monitored; and

visually capturing a movement of the at least one entity on the display screen, wherein the captured movement comprises at least one attribute associated with the at least one entity.

2. The method of claim 1 further comprising generating an alert if the at least one attribute matches the at least one criterion associated with the event of interest.

3. The method of claim 2, wherein the at least one attribute matches the at least one criterion when the at least one attribute crosses a predetermined threshold, the at least one criterion comprising the predetermined threshold.

4. The method of claim 1, wherein the at least one criterion is specified as at least one of a geometrical constraint, a location constraint, a direction of movement constraint, and a temporal constraint.

5. The method of claim 4, wherein the geometrical constraint comprises specifying a threshold as at least one of crossing a line, entering or leaving a zone within the area, and dwelling at a location within the area.

6. The method of claim 4, wherein the temporal constraint comprises specifying a threshold as an amount of time associated with a location of the at least one entity.

7. The method of claim 4, wherein the location constraint comprises specifying a threshold as presence at a particular location.

8. The method of claim 4, wherein the direction of movement constraint comprises specifying a threshold as an expected direction of movement at a portion within the area.

9. The method of claim 2, wherein the alert is at least one of an audio alert and a video alert.

10. The method of claim 1 further comprising specifying a monitoring criterion visually on a display screen to monitor the movement of the at least one entity in detail.

11. The method of claim 10, wherein the monitoring criterion is specified on the visually captured movement of the at least one entity.

12. The method of claim 1, wherein visually capturing a movement of the at least one entity comprises representation of a position of the at least one entity by rectangular regions, the size of the rectangular regions varying based upon the time spent by the at least one entity at the position.

13. The method of claim 1 further comprising modifying the at least one criterion visually on a display screen.

14. The method of claim 1 further comprising:

recording the event of interest in detail, and

tagging the at least one entity associated with the event of interest.

15. The method of claim 14 further comprising recording the movement of the at least one entity tagged as being associated with the event of interest.

16. A system for monitoring an entity within an area, the system comprising:

an input and output device comprising a display screen, the input and output device configured to receive at least one criterion associated with an event of interest, the at least one criterion specified visually on a display screen;

at least one image capture device configured to provide visual images of the area and at least one entity within the area; and

a monitoring module configured to identify at least one entity to be monitored, visually capture a movement of the at least one entity on the display screen, wherein the captured movement comprises at least one attribute associated with the at least one entity.

17. The system of claim 16 wherein the monitoring module is further configured to generate an alert through the input and output device, if the at least one attribute matches the at least one criterion associated with the event of interest.

18. The system of claim 16, wherein the at least one image capture device comprises a plurality of image capture devices, and wherein the monitoring module is configured to switch display from one image capture device to another image capture device based upon the movement of the entity in the field of view of the corresponding image capture device.

19. The system of claim 16, wherein the input and output device is configured to receive specification of the at least one criterion as at least one of a geometrical constraint, a location constraint, a direction of movement constraint, and a temporal constraint.

20. The system of claim 16, wherein the monitoring module is further configured to record the event of interest in detail, tag the at least one entity associated with the event of interest, and record the movement of the at least one entity tagged as being associated with the event of interest.

21. The system of claim 20, wherein the monitoring module is configured to receive and apply a modified criterion to analyze the recorded event of interest and/or the movement of the tagged entity.
