Abstract

The present disclosure relates to a body extremity temperature change monitoring system and method. More specifically, the present disclosure relates to a body extremity temperature change monitoring system and method, which can monitor a temperature change by recognizing a body extremity and measuring the body temperature of the recognized body extremity. The body extremity temperature change monitoring system comprises: an image data acquisition unit that acquires body extremity image data including a hand or a foot; a segmented area generation unit; and a body extremity temperature map generation unit that generates a body extremity temperature map using temperature data for each of the segmented areas, wherein the body extremity is defined to include base parts having a palm and a foot sole, and branch parts having fingers and toes.

First claim

What is claimed is:

1 . A body extremity temperature change monitoring system comprising:
an image data acquisition unit that acquires body extremity image data, which is image data of a body extremity including a hand and a foot; a segmented area generation unit that segments the body extremity image data according to a preset reference to generate two or more segmented areas; and a body extremity temperature map generation unit that generates a body extremity temperature map using temperature data for each of the segmented areas, wherein the body extremity is defined to include base parts having a palm and a foot sole, and branch parts having fingers and toes, wherein the segmented area generation unit comprises a body extremity type classification module that identifies a type of the body extremity; and an area segmentation module that generates at least two segmented areas using the preset reference according to the type of the body extremity, wherein the body extremity type classification module acquires a boundary line for the body extremity using the body extremity image data and compares the average length of the branch parts with the average length of the base parts, to classify, according to the preset reference, the body extremity type into the hand or the foot.

2 . The body extremity temperature change monitoring system as claimed in claim 1 , wherein the image data acquisition unit comprises:
an image data acquisition module that acquires image data of the body extremity; and a thermal image data acquisition module that acquires thermal image data of the body extremity.

3 . The body extremity temperature change monitoring system as claimed in claim 1 , wherein when the type of the body extremity is the hand, the preset reference includes any one of 24-area segmentation, 32-area segmentation, and 5-line segmentation, and when the type of the body extremity is the foot, the preset reference includes any one of 19-area segmentation and 5-line segmentation.

4 . The body extremity temperature change monitoring system as claimed in claim 2 , wherein the body extremity temperature map generation unit comprises:
an image data merge module that generates merged image data by mapping the thermal image data to the image data including the segmented areas; and a body temperature distribution data generation module that generates the body extremity temperature map, which is temperature data for each segmented area, using the merged image data.

5 . The body extremity temperature change monitoring system as claimed in claim 4 , wherein the body extremity temperature map is acquired at a preset period to be generated to include time-series information.

6 . The body extremity temperature change monitoring system as claimed in claim 1 , further comprising a body temperature change analysis unit that observes a user's body temperature change using the body extremity temperature map and infers a user's state change according to the body temperature change using the preset reference.

7 . The body extremity temperature change monitoring system as claimed in claim 6 , wherein the body temperature change analysis unit comprises:
a body temperature change map generation module that calculates the user's body temperature change for a preset time using the body extremity temperature map and generates a body temperature change map using the body temperature change for each segmented area; and a state change inference module that compares a preset body temperature change reference with the body temperature change map to perform defining on the user's state change.

8 . The body extremity temperature change monitoring system as claimed in claim 1 , wherein the body extremity type classification module performs numbering or coloring for each of the segmented areas so that the segmented areas are distinguished from each other.

9 . A body extremity temperature change monitoring method comprising:
an image data acquisition step of, by using an image data acquisition unit, acquiring body extremity image data that is image data of a body extremity including a hand and a foot; a segmented area segmentation step of, by using a segmented area generation unit, segmenting the body extremity image data according to a preset reference to generate two or more segmented areas; and a body extremity temperature map generation step of, by using a body extremity temperature map generation unit, generating a body extremity temperature map using temperature data for each of the segmented areas, wherein the body extremity is defined to include base parts having a palm and a foot sole, and branch parts having fingers and toes, wherein the segmented area generation step comprises identifying a type of the body extremity; and generating two or more segmented areas using the preset reference according to the type of the body extremity, wherein in the step of identifying the type of the body extremity, a boundary line for the body extremity is acquired using the body extremity image data, and, according to the preset reference, the type of the body extremity is classified into the hand or the foot by comparing the average length of the branch parts with the average length of the base parts.

10 . The body extremity temperature change monitoring method as claimed in claim 9 , wherein the image data acquisition step comprises:
acquiring image data of the body extremity; and acquiring thermal image data of the body extremity.

11 . The body extremity temperature change monitoring method as claimed in claim 9 , wherein when the type of the body extremity is the hand, the preset reference includes any one of 24-area segmentation, 32-area segmentation, and 5-line segmentation, and when the type of the body extremity is the foot, the preset reference includes any one of 19-area segmentation and 5-line segmentation.

12 . The body extremity temperature change monitoring method as claimed in claim 10 , wherein the body extremity temperature map generation step comprises:
an image data merging step of generating merged image data by mapping the thermal image data to the image data including the segmented areas; and a body temperature distribution generation step of generating the body extremity temperature map, which is temperature data for each segmented area, using the merged image data.

13 . The body extremity temperature change monitoring method as claimed in claim 12 , wherein the body extremity temperature map is acquired at a preset period to be generated to include time-series information.

14 . The body extremity temperature change monitoring method as claimed in claim 9 , further comprising observing, by using a body temperature change analysis unit, the user's body temperature change using the body extremity temperature map, and analyzing the body temperature change by inferring a user's state change according to the body temperature change using the preset reference.

15 . The body extremity temperature change monitoring method as claimed in claim 14 , further comprising:
calculating the user's body temperature change for a preset time using the body extremity temperature map, and generating a body temperature change map using the body temperature change for each segmented area; and comparing the body temperature change map with a preset body temperature change reference to define a change in the user's state.
