Abstract
A method of automatically tracking urine in a toilet includes creating a background image of an interior of a toilet bowl using an image sensor, wherein the background image shows the interior of the toilet bowl. The method also includes acquiring an image of the interior of the toilet bowl using the image sensor, wherein the acquired image shows urine and a collecting and tracing member in the interior of the toilet bowl. The method further includes producing a difference image that shows a difference between the acquired image and the background image, and processing the difference image to identify a location of the urine and the collecting and tracking member, and moving the collecting and tracking member to the identified location of the urine.
