Abstract

The present invention discloses a game doll recognition system, a recognition method, and a game system using the same. The game doll recognition system is capable of recognizing a plurality of game dolls; it includes: a data storage unit storing identification data of the game dolls; an image capturing unit capturing at least one picture of an game doll to be recognized; a processor comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized in the picture; and a display unit showing the identity of the game doll to be recognized.

Claims

1. A game doll recognition system capable of recognizing a plurality of game dolls, comprising:

a data storage unit for storing identification data of the game dolls, wherein the identification data are related to the images of the game dolls;

an image capturing unit for capturing at least one picture of at least a portion of a game doll to be recognized;

a processor for comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized; and

a display unit showing the identity of the game doll to be recognized.

2. The game doll recognition system of claim 1, further comprising a supporting stage for supporting the game doll to be recognized to assist the image capturing unit to capture the picture.

3. The game doll recognition system of claim 2, wherein the supporting stage includes a positioning mark indicating a position or an angle for placing the game doll to be recognized.

4. The game doll recognition system of claim 2, wherein the supporting stage includes a platform for supporting the game doll to be recognized, and the platform has a height which is adjustable.

5. The game doll recognition system of claim 4, wherein the supporting stage further includes a background shelter appearing when the platform is descended.

6. The game doll recognition system of claim 1, further comprising:

a light source emitting light on the game doll to be recognized, wherein the image capturing unit receives the light reflected by the game doll.

7. The game doll recognition system of claim 1, wherein the image capturing unit further captures a scene image.

8. The game doll recognition system of claim 2, further comprising a backdrop serving as a background of the game doll to be recognized in the picture.

9. The game doll recognition system of claim 1, further comprising:

a host including the processor and the data storage unit, the host outputting the identity of the game doll to be recognized to the display unit.

10. The game doll recognition system of claim 1, wherein the processor, the data storage unit, and the image capturing unit are integrated into a single device.

11. The game doll recognition system of claim 1, wherein the identification data are the images of the game dolls, and the processor compares statistic hue data of pixels of each image with statistic hue data of pixels of the picture to determine which game doll in the images is the most similar to the game doll to be recognized in the picture.

12. The game doll recognition system of claim 11, wherein the processor compares a portion of the picture having a characteristic pattern with a portion of each image to determine which game doll in the images is the most similar to the game doll to be recognized in the picture.

13. The game doll recognition system of claim 12, wherein the processor compares the portion of the picture with the portion of each image according to local binary pattern, local edge pattern, scale invariant feature transformer, or edge detection.

14. A recognition method for use in a game doll recognition system, comprising:

storing identification data of game dolls;

capturing at least one picture of at least a portion of a game doll to be recognized;

comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized; and

displaying the identity of the game doll to be recognized.

15. The recognition method for use in the game doll recognition system of claim 14, further comprising a step of indicating a position or an angle for placing the game doll to be recognized.

16. The recognition method for use in the game doll recognition system of claim 14, wherein the identification data are the images of the game dolls, and the step of comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized comprises:

comparing statistic hue data of pixels of each image with statistic hue data of pixels of the picture to determine which game doll in the images is the most similar to the game doll to be recognized in the picture.

17. The recognition method for use in the game doll recognition system of claim 14, wherein the identification data are the images of the game dolls, and the step of comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized comprises:

comparing a portion of the picture having a characteristic pattern with a corresponding portion of each image to determine which game doll in the images is the most similar to the game doll to be recognized in the picture.

18. The recognition method for use in the game doll recognition system of claim 17, wherein the portion of the picture is compared with the portion of each image according to local binary pattern, local edge pattern, scale invariant feature transformer, or edge detection.

19. A game system capable of recognizing a game doll, comprising:

at least one game doll to be recognized;

a data storage unit storing identification data of a plurality of game dolls playing a plurality of roles in a game;

an image capturing unit capturing at least one picture of the game doll to be recognized;

a processor comparing the identification data with at least a part of the picture to verify the identity of the game doll to be recognized; and

a display unit showing the identity of the game doll to be recognized.

20. The game system capable of recognizing a game doll of claim 19, further comprising a supporting stage supporting the game doll to be recognized to assist the image capturing unit to capture the picture.

21. The game system capable of recognizing a game doll of claim 20, wherein the supporting stage includes a positioning mark indicating a position or an angle for placing the game doll to be recognized.

22. The game system capable of recognizing a game doll of claim 20, wherein the supporting stage includes a platform for supporting the game doll to be recognized, and the platform has a height which is adjustable.

23. The game system capable of recognizing a game doll of claim 19, further comprising:

a host including the processor and the data storage unit, the host outputting the identity of the game doll to be recognized to the display unit.

24. The game system capable of recognizing a game doll of claim 19, wherein the processor, the data storage unit, and the image capturing unit are integrated into a single device.

25. The game system capable of recognizing a game doll of claim 19, wherein the identification data are the images of the game dolls, and the processor compares statistic hue data of pixels of each image with statistic hue data of pixels of the picture to determine which game doll in the images is the most similar to the game doll to be recognized in the picture.

26. The game system capable of recognizing a game doll of claim 19, wherein the processor compares a portion of the picture having a characteristic pattern with a corresponding portion of each image to determine which game doll in the images is the most similar to the game doll to be recognized in the picture
