Abstract

A verification method for people counting includes steps of displaying a people counting video by a display device, wherein the people counting video shows an entry and exit boundary and an accumulated number of persons; when at least one person exists in the people counting video, displaying an initial position and a current position of each of the at least one person by the display device; determining whether each of the at least one person passes across the entry and exit boundary according to the initial position and the current position of each of the at least one person by a user, so as to determine whether the accumulated number of persons is incorrect; and when the user determines that the accumulated number of persons is incorrect, receiving a modified number of persons from the user by an input device.

Claims

1. A verification method for people counting comprising steps of:

displaying a people counting video by a display device, wherein the people counting video shows an entry and exit boundary and an accumulated number of persons;

when at least one person exists in the people counting video, displaying an initial position and a current position of each of the at least one person by the display device;

determining whether each of the at least one person passes across the entry and exit boundary according to the initial position and the current position of each of the at least one person by a user, so as to determine whether the accumulated number of persons is incorrect;

when the user determines that the accumulated number of persons is incorrect, receiving a modified number of persons from the user by an input device;

when a number of the persons is larger than or equal to a predetermined value, displaying the people counting video with a first speed by the display device; and

when the number of the persons is smaller than the predetermined value, displaying the people counting video with a second speed by the display device, wherein the second speed is larger than the first speed.

2. The verification method for people counting of claim 1, wherein the accumulated number of persons comprises at least one of an accumulated number of entry persons and an accumulated number of exit persons.

3. The verification method for people counting of claim 1, further comprising step of:

when the at least one person exists in the people counting video, displaying a pattern corresponding to the person by the display device.

4. The verification method for people counting of claim 3, further comprising steps of:

when a height of the person is larger than or equal to a predetermined height, displaying the pattern with a first size by the display device; and

when the height of the person is smaller than the predetermined height, displaying the pattern with a second size by the display device, wherein the second size is smaller than the first size.

5. The verification method for people counting of claim 3, further comprising step of:

when the person approaches a screen boundary of the people counting video, displaying the pattern with an eye-catching effect by the display device.

6. The verification method for people counting of claim 1, further comprising step of:

when the at least one person exists in the people counting video, displaying a line pattern connecting the initial position and the current position of each of the at least one person by the display device.

7. A verification system for people counting comprising:

a display device displaying a people counting video, the people counting video showing an entry and exit boundary and an accumulated number of persons; and

an input device communicating with the display device;

wherein when at least one person exists in the people counting video, the display device displays an initial position and a current position of each of the at least one person;

a user determines whether each of the at least one person passes across the entry and exit boundary according to the initial position and the current position of each of the at least one person, so as to determine whether the accumulated number of persons is incorrect; and

when the user determines that the accumulated number of persons is incorrect, the input device receives a modified number of persons from the user;

wherein when a number of the persons is larger than or equal to a predetermined value, the display device displays the people counting video with a first speed;

when the number of the persons is smaller than the predetermined value, the display device displays the people counting video with a second speed;

the second speed is larger than the first speed.

8. The verification system for people counting of claim 7, wherein the accumulated number of persons comprises at least one of an accumulated number of entry persons and an accumulated number of exit persons.

9. The verification system for people counting of claim 7, wherein when the at least one person exists in the people counting video, the display device displays a pattern corresponding to the person.

10. The verification system for people counting of claim 9, wherein when a height of the person is larger than or equal to a predetermined height, the display device displays the pattern with a first size;

when the height of the person is smaller than the predetermined height, the display device displays the pattern with a second size;

the second size is smaller than the first size.

11. The verification system for people counting of claim 9, wherein when the person approaches a screen boundary of the people counting video, the display device displays the pattern with an eye-catching effect.

12. The verification system for people counting of claim 7, wherein when the at least one person exists in the people counting video, the display device displays a line pattern connecting the initial position and the current position of each of the at least one person.

13. A non-transitory computer readable storage medium for storing a set of computer-executable instructions, when executed, causing a display device to perform steps of:

displaying a people counting video, wherein the people counting video shows an entry and exit boundary and an accumulated number of persons;

displaying an initial position and a current position of each of at least one person when the at least one person exists in the people counting video, wherein a user determines whether each of the at least one person passes across the entry and exit boundary according to the initial position and the current position of each of the at least one person, so as to determine whether the accumulated number of persons is incorrect;

receiving a modified number of persons from the user by an input device when the user determines that the accumulated number of persons is incorrect;

displaying the people counting video with a first speed when a number of the persons is larger than or equal to a predetermined value; and

displaying the people counting video with a second speed when the number of the persons is smaller than the predetermined value, wherein the second speed is larger than the first speed.

14. The non-transitory computer readable storage medium of claim 13, the set of computer-executable instructions, when executed, further causing the display device to perform step of:

displaying a pattern corresponding to the person when the at least one person exists in the people counting video.

15. The non-transitory computer readable storage medium of claim 14, the set of computer-executable instructions, when executed, further causing the display device to perform steps of:

displaying the pattern with a first size when a height of the person is larger than or equal to a predetermined height; and

displaying the pattern with a second size when the height of the person is smaller than the predetermined height, wherein the second size is smaller than the first size.

16. The non-transitory computer readable storage medium of claim 14, the set of computer-executable instructions, when executed, further causing the display device to perform step of:

displaying the pattern with an eye-catching effect when the person approaches a screen boundary of the people counting video.

17. The non-transitory computer readable storage medium of claim 13, the set of computer-executable instructions, when executed, further causing the display device to perform step of:

displaying a line pattern connecting the initial position and the current position of each of the at least one person when the at least one person exists in the people counting video.
