  • Droplet measurement system, droplet measurement method and computer readable recording device
    Patent number: 10583248
    Abstract: A droplet measurement system is provided with: an imaging device placed to locate a tip part of a nozzle and the entire liquid hanging down from the nozzle within a field of view; an image generation unit that generates a plurality of images that capture the state in which droplets are dripping down from the nozzle based on image data output from the imaging device; a dripping detection unit that detects, from the plurality of images, a dripping-detected image in which the fact that a droplet has departed from the nozzle is detected; and a volume calculation unit that calculates the volume of the droplet based, at least, on an image-before-dripping, which is generated a predetermined number of frames before the dripping-detected image and capturing liquid hanging down from the nozzle and on a reference image that captures at least the tip part of the nozzle.
