This study proposes a new method of urine flow measurement by image processing. There are problems of existing uroflowmeters such as the high price and the possibility of nosocomial infection when using cups. This study aims to estimate the flow rate and volume of urine simulated liquid discharged in air by using only one camera. Continuous pictures of liquid were imaged for extracting parameters including initial velocity of liquid. We estimated the volume of liquid based on multiple cylindrical model. From the experiment, the average estimation accuracy was within the range of 3%. This result showed the possibility of applying this method for urine volume estimation. Furthermore, this method includes the output of urinary flow rate curve. This study proposed a new method of simple urine flow management.
