Abstract

An excrement judgement system according to the embodiment including: an acquisition unit that acquires image information on an image in which excrement excreted in a defecation action per time is captured; a determination unit that determines properties of a plurality of stools included in the image information and stool amounts corresponding to the properties of the plurality of stools; and an outputting unit that associates the properties of the plurality of stools and the stool amounts corresponding to the properties of the plurality of stools that are determined by the determination unit, and outputs the associated properties and stool amounts to a device to be displayed.

Claims (32)

1. An excrement judgement system comprising:

an acquisition device that acquires image information including information on a plurality of stools excreted in a defecation action;

a determination device that determines types of a defining property, which is based on stool hardness, of the plurality of stools included in the image information and stool amounts corresponding the types of the plurality of stools; and

an outputting device that outputs a content associating the types of the plurality of stools with the stool amounts to a device to be displayed,

a model information storage that stores therein a model information used for identifying a stool region based on a boundary of the stool included in the image information,

wherein the determination device determines the types of the plurality of stools by using the model information stored in the model information storage,

wherein the outputting device outputs, in a case where there presents two or more stools for which types are determined, a total value of the stool amounts of the two or more stools, and

wherein the outputting device outputs, based on a ratio of a stool amount corresponding to the property of each of the stools to a total amount of stool amounts in the defecation action per time, a representative value of the properties of the stools.

2. The excrement judgement system according to claim 1 ,

wherein the outputting device outputs, in a case where there presents two or more stools having a same type among the plurality of stools for which types are determined, a total value of the stool amounts of the two or more stools having the same type.

3. The excrement judgement system according to claim 1 ,

wherein the acquisition device receives an image that is captured after a target person performs the defecation action and before the target person flushed the toilet.

4. The excrement judgement system according to claim 1 ,

wherein the determination device executes a stool identification determination process by using a machine learning model information that stored in the model information storage.

5. The excrement judgement system according to claim 1 ,

wherein the outputting device outputs, based on the properties of the plurality of stools in the defecation action per time, a representative value of the properties of the stools.

6. An excrement judgement method comprising:

acquiring image information including information on a plurality of stools excreted in a defecation action;

determining types of a defining property, which is based on stool hardness, of the plurality of stools included in the image information and stool amounts corresponding the types of the plurality of stools; and

outputting a content associating the types of the plurality of stools with the stool amounts to a device to be displayed;

storing a model information used for identifying a stool region based on a boundary of the stool included in the image information;

determining the types of the plurality of stools by using the model information stored;

outputting, in a case where there presents two or more stools for which types are determined, a total value of the stool amounts of the two or more stools; and

outputting, based on a ratio of a stool amount corresponding to the property of each of the stools to a total amount of stool amounts in the defecation action per time, a representative value of the properties of the stools.

7. An excrement judgement device comprising:

an acquisition device that acquires image information including information on a plurality of stools excreted in a defecation action;

a determination device that determines types of a defining property, which is based on stool hardness, of the plurality of stools included in the image information and stool amounts corresponding the types of the plurality of stools; and

an outputting device that outputs a content associating the types of the plurality of stools with the stool amounts to a device to be displayed,

a model information storage that stores therein a model information used for identifying a stool region based on a boundary of the stool included in the image information,

wherein the determination device determines the types of the plurality of stools by using the model information stored in the model information storage,

wherein the outputting device outputs, in a case where there presents two or more stools for which types are determined, a total value of the stool amounts of the two or more stools, and

wherein the outputting device outputs, based on a ratio of a stool amount corresponding to the property of each of the stools to a total amount of stool amounts in the defecation action per time, a representative value of the properties of the stools.
