Calibration methods for ostomy appliance tools
A method for operating an accessory device to capture calibration data. The method can include capturing an image of a portion of a user's body that includes the user's stoma and at least two reference locations, and storing distance scale information representative of a distance between the two reference locations. The method further includes processing the captured image, including: identifying the reference locations, identifying the stoma, and generating calibration data representative of one or more stoma parameters as a function of the identified reference locations, identified stoma and the distance scale information. The calibration data can be stored.
1 . A method for processing image data of a stoma, the method comprising:
obtaining, from a camera, first image data of a portion of a user's body that includes a stoma of the user and a set of reference locations that comprises a mark applied to the user's body;
determining, based on the image data and the set of reference locations, a set of parameters corresponding to the stoma, the set of parameters comprising at least one of:
a shape of the stoma;
a location of the stoma;
a size of the stoma; or
an orientation of the stoma; and
storing the set of parameters for subsequent processing, the subsequent processing comprising:
generating, using the set of parameters, indicia that represents the stoma according to the first image data; and
displaying, over second image data that includes the stoma of the user, the generated indicia.
2 . The method of claim 1 , wherein the set of reference locations includes a feature of the user's body.
3 . The method of claim 1 , wherein the plurality set of reference locations includes a feature of the stoma.
4 . The method of claim 1 , wherein the mark is on a substrate adhesively attached to the user's body.
5 . The method of claim 1 , wherein the set of reference locations includes at least two of:
a feature of the user's body;
a feature of the stoma; and
the mark applied to the user's body.
6 . The method of claim 1 , wherein the set of parameters is determined using object recognition to identify the stoma within the first image data.
7 . The method of claim 1 , wherein determining the set of parameters comprises receiving information through a user interface.
8 . A method, performed by an accessory device, for processing image data of a stoma, the method comprising:
obtaining, from a camera of the accessory device, first image data of a portion of a user's body that includes a stoma of the user and a set of reference locations that comprises a mark applied to the user's body;
determining, based on the image data and the set of reference locations, a set of parameters corresponding to the stoma, the set of parameters comprising at least one of:
a shape of the stoma;
a location of the stoma;
a size of the stoma; or
an orientation of the stoma;
generating, using the set of parameters, indicia that represents the stoma according to the first image data; and
displaying, on a screen of the accessory device and over second image data that includes the stoma of the user, the generated indicia.
9 . The method of claim 8 , wherein the set of reference locations includes at least two of:
a feature of the user's body;
a feature of the stoma; and
the mark applied to the user's body.
10 . The method of claim 8 , wherein the mark is on a substrate adhesively attached to the user's body.
11 . The method of claim 8 , wherein the set of parameters is determined using object recognition to identify the stoma within the first image data.
12 . The method of claim 8 , wherein determining the set of parameters comprises receiving information through a user interface of the accessory device.
13 . A system comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the system to perform a set of operations, the set of operations comprising:
obtaining first image data of a portion of a user's body that includes a stoma of the user and a set of reference locations that comprises a mark applied to the user's body;
determining, based on the image data and the set of reference locations, a set of parameters corresponding to the stoma, the set of parameters comprising at least one of:
a shape of the stoma;
a location of the stoma;
a size of the stoma; or
an orientation of the stoma; and
storing the set of parameters for subsequent processing, the subsequent processing comprising:
generating, using the set of parameters, indicia that represents the stoma according to the first image data; and
generating, for display to a user, a visual representation that includes the generated indicia over second image data, the second image data including the stoma of the user.
14 . The system of claim 13 , wherein the set of reference locations includes at least two of:
a feature of the user's body;
a feature of the stoma; and
the mark applied to the user's body.
15 . The system of claim 13 , wherein the set of parameters is determined using object recognition to identify the stoma within the first image data.
16 . The system of claim 13 , wherein determining the set of parameters comprises processing information that was received from the user through a user interface.
17 . The system of claim 13 , wherein the set of reference locations includes a feature of the user's body.
18 . The system of claim 13 , wherein the set of reference locations includes a feature of the stoma.
19 . The system of claim 13 , wherein the mark is on a substrate adhesively attached to the user's body.
