Urination analysis method, urination analysis device, and non-transitory computer readable recording medium

A urination analysis device that analyzes urination, the urination analysis device comprising:

• a processor;
• and
• a memory including a program that, when executed by the processor, causes the processor to:
• acquire image data captured by a camera which is located at a toilet to photograph a bowl of the toilet;
• calculate a urination pixel number being a number of pixels of an image showing urination from the image data when the urination by a user is detected by image recognition of the image data;
• calculate, based on a change in the urination pixel number, at least one of a flow momentum value indicating flow momentum of the urination, a urine quantity indicating a quantity of urine, or a urine specific gravity indicating a specific gravity of the urine;
• and
• output the at least one of the flow momentum value, the urine quantity, or the urine specific gravity, wherein
• the urine quantity is calculated based on a first integral value of increase amounts per unit time with respect to the urination pixel number.

A non-transitory computer readable recording medium storing a urination analysis program causing a computer to serve as a urination analysis device that analyzes urination, the urination analysis program comprising:

• further causing the computer to execute:
• acquiring image data captured by a camera which is located at a toilet to photograph a bowl of the toilet;
• calculating a urination pixel number being a number of pixels of an image showing urination from the image data when the urination by a user is detected by image recognition of the image data;
• calculating, based on a change in the urination pixel number, at least one of a flow momentum value indicating flow momentum of the urination, a urine quantity indicating a quantity of urine, or a urine specific gravity indicating a specific gravity of the urine;
• and
• outputting the at least one of the flow momentum value, the urine quantity, or the urine specific gravity, wherein
• the urine quantity is calculated based on a first integral value of increase amounts per unit time with respect to the urination pixel number.
