<p>The present invention relates to a method for measuring a flow rate of a ringer solution using a smartphone capable of using a mobile terminal such as the smartphone having a camera instead of a high performance calculation apparatus for calculating a threshold value, capable of a quick setting of an optimized binary threshold value, and capable of quickly measuring a falling interval of the ringer solution. The method comprises: a standard image frame acquisition step of capturing a ringer solution bottle with the smartphone, acquiring a frame after a drop of the ringer solution is fallen from a frame before the drop of the ringer solution is fallen as standard image frames, and writing a histogram per each acquired standard image frame; an optimized binary threshold value drawing step of drawing a standard top threshold Th and a standard bottom threshold value Tl based on the standard image frames acquired from the standard image frame acquisition step and the histogram, and selecting one between the standard top threshold value Th or the standard bottom threshold value Tl as an optimized binary threshold T from the threshold values of the frames before and after the drop of the ringer solution is fallen; and a ringer solution falling interval measurement step of measuring the number of a sunspot inside the frames based on the optimized binary threshold value T.</p> |
