Abstract

A system and methodology that counts a number of moving objects including the pedestrians within predetermined areas. According to certain embodiments, a system comprises an image sensing device and a data processing device. The image sensing device is situated at a predetermined area. The image sensing device retrieves a series of images of the moving objects within the predetermined area. The data processing device is coupled to the image sensing device. The data processing device processes the retrieved image to generate a dynamic background of the first predetermined area and determine a flow of the moving objects thereon.

Claims

1. A system for generating a dynamic background of a first predetermined location, suitable for an analyzing system operating from a time point t1 until a time point tn, said system for generating a dynamic background comprising:

a recording unit for recording a first image to an n-th image at the time point t1 until the time point tn respectively; and

an analyzing unit for analyzing every pixel in said n images, the most frequently appeared image value being determined as background value of said pixel, said background value of each pixel being then integrated into said dynamic background of said first predetermined location.

2. The system according to claim 1, wherein said analyzing system retrieves said first image to said n-th image at said time point t1 until said time point tn respectively.

3. The system according to claim 1, wherein each time interval between n consecutive time points is the same.

4. The system according to claim 1, wherein said dynamic background of said first predetermined location is transmitted to said analyzing system, and said analyzing system analyzes data of said n images.

5. A method for generating a dynamic background of a first predetermined location comprising the steps of:

providing a time point t1 until a time point tn, where n is a positive integer;

recording a first image to an n-th image at said time point t1 until said time point tn respectively; and

analyzing every pixel in said n images, the most frequently appeared image value being determined as background value of said pixel, said background value of each pixel being then integrated into said dynamic background of said first predetermined location.

6. The method according to claim 5, further comprising the step of retrieving said first image to said n-th image by an analyzing system at said time point t1 until said time point tn respectively.

7. The method according to claim 5, wherein each time interval between n consecutive time points is the same.

8. A system for analyzing pedestrian flow comprising:

an image collecting unit situated at a first predetermined location for collecting an image of said first predetermined location;

a storing unit for storing the image collected by said image collecting unit; and

a determining unit for determining the pedestrian flow in said first predetermined location, said determining unit has a generating module for generating a background of said first predetermined location and a discriminating module for discriminating said pedestrian flow in said first predetermined location, wherein said generating module records first image to n-th image collected by said image collecting unit at time point t1 until time point to respectively, and chooses one most frequently appeared image of said n images, the most frequently appeared image being determined as said background of said first predetermined location.

9. The system according to claim 8, wherein said first predetermined location is an intersection.

10. The system according to claim 8, wherein said determining unit is situated at said first predetermined location.

11. The system according to claim 8, wherein said determining unit is situated at a second predetermined location.

12. The system according to claim 8, wherein said storing unit is situated at said first predetermined location.

13. The system according to claim 8, wherein said storing unit is situated at a second predetermined location.

14. The system according to claim 8, wherein said storing unit is situated at a third predetermined location.

15. The system according to claim 8, wherein said image collecting unit is waterproof.

16. The system according to claim 8, wherein said image collecting unit is wireless.

17. The system according to claim 8, wherein said image collecting unit is a CCD (Charge Coupled Device) camera.
