US20190122038

1. An image detection method for determining a posture of a user, comprising: (5) (5)

obtaining a reference image of a user in a region of interest (ROI);

obtaining a test image of the user in the ROI;

executing a feature matching analysis on a feature parameter of the test image and a feature parameter of the reference image to obtain user similarity information of the test image and the reference image;

executing a pixel distribution analysis for the test image to obtain user pixel distribution information; and

determining the posture of the user based on the user similarity information and the user pixel distribution information.

2. The image detection method as claimed in claim 1, wherein the pixel distribution analysis is utilized to accumulate pixels for a user sketch of the test image along a first direction to obtain the user pixel distribution information. (0)

3. The image detection method as claimed in claim 1, wherein the test image is different from the reference image. (0)

4. The image detection method as claimed in claim 1, further comprising: (0) (1)

5. The image detection method as claimed in claim 1, wherein the ROI is a bed on which the user is lying, and the feature parameter comprises any one of limbs, any one of facial features, trunk of the user, or a specific pattern of an article of clothing worn by the user. (0)

6. The image detection method as claimed in claim 1, wherein the similarity information of the feature parameter of the test image and the feature parameter of the reference image is calculated to determine whether it is greater than a first predetermined value or not, and the pixel distribution analysis is utilized to calculate a pixel accumulation value of the user sketch along the first direction respectively based on a sequence of a second direction, and whether the user pixel distribution information of the pixel accumulation value is greater than a second predetermined value or not. (3) (0)

7. The image detection method as claimed in claim 6, wherein: (0) (2)

8. The image detection method as claimed in claim 6, wherein: (0) (2)

9. The image detection method as claimed in claim 6, wherein the first direction extends from head of the user to foot of the user, and the second direction is different from the first direction. (1) (0)

11. An image detection device, comprising: (2) (3)

a sensor, configured to detect a test image and a reference image of a user in a region of interest (ROI); and

a processor, comprising: a feature matching module, configured to execute a feature matching analysis of a feature parameter of the test image and a feature parameter of the reference image to obtain user similarity information of the test image and the reference image, and execute a pixel distribution analysis for the test image to obtain user pixel distribution information; and

a determination module, configured to determine a posture of the user based on the user similarity information and the user pixel distribution information.

12. The image detection device as claimed in claim 11, wherein the pixel distribution analysis is utilized to accumulate pixels for a user sketch of the test image along a first direction to obtain the user pixel distribution information. (0)

13. The image detection device as claimed in claim 11, wherein the processor calculates the similarity information of the feature parameter of the test image and the feature parameter of the reference image to determine whether it is greater than a first predetermined value or not, and the pixel distribution analysis is utilized to calculate a pixel accumulation value of the user sketch along the first direction respectively based on a sequence of a second direction, and the processor calculates whether the user pixel distribution information of the pixel accumulation value is greater than a second predetermined value or not. (3) (0)

14. The image detection device as claimed in claim 13, wherein: (0) (2)

15. The image detection device as claimed in claim 13, wherein: (0) (2)

16. The image detection device as claimed in claim 13, wherein the first direction extends from the head of the user to the foot of the user, and the second direction is different from the first direction. (1) (0)
