  • Measurement of velocity fields in ball mills SpringerLink

    This paper describes a computer vision technique used in measuring the velocity field related to the motion of balls in a ball mill. A camera combined with two color flashes facing an experimental ball mill is used to take pairs of pictures by triggering the flashes in sequence with a time interval Δt. In order to ensure consistency the pictures are of different colors and in a single frame.
