Example Embodiment
[0041] The particle-bubble collision detection method of the present invention can detect whether the particles in the liquid collide with the bubbles. In a specific embodiment of the present invention, the particles to be tested are made into a thin slurry with a particle concentration of less than 2wt%, placed in a beaker and stirred with a magnetic stirrer, so that the particles in the slurry are dispersed and do not aggregate. Use a rubber-head dropper to suck the pulp, insert the dropper below the liquid level of the observation room, and the particles settle under the action of gravity.
[0042] The technical solution of the present invention will be further described below in conjunction with specific embodiments.
[0043] Such as figure 1 As shown, the particle-bubble collision detection method based on Otsu image segmentation includes the following steps:
[0044] 1) Drop the slurry into the liquid (distilled water), use a CCD camera to take multiple shots of the trajectory...
