Claim 6:
7. A method of automatically tracking and collecting urine in a container of a medical urine detection device, the method comprising:
acquiring “n” groups of image data of an interior of the container using an image sensor located on an inner side wall of the container and calculating an average value of the image data as a background image, wherein the background image is an image showing no urine and no collecting and tracking member in the interior of the container, and storing the background image;
acquiring an image of the interior of the container using the image sensor, wherein the acquired image shows urine from a user of the medical urine detection device and the collecting and tracking member;
identifying a location of the urine and a location of the collecting and tracking member by processing the acquired image to generate a difference image, wherein the difference image shows a difference between the acquired image of the interior of the container and the background image, and then processing the difference image;
moving the collecting and tracking member to the identified location of the urine; and
collecting a sample of the urine in a liquid collection head of the collecting and tracking member.
