Experimental setup to generate the event-based ball dataset. The illumination panel is shown transparent for a better overview. Starting from the upper cylinder, the balls roll over an inclined plane and cross the camera’s FoV diagonally. As the balls are in free fall they rotate and the camera is able to perceive the object’s pattern in motion. In order to record a large amount of data the cycle is automated by pneumatic conveyance, returning the ball back to the starting point.
