i) values obtained from the analysis of motion in the plane XOY (Fig. 5)
will be determine: the travel time of solid particle on monitoring distance; the
solid particle trajectory on oscillating surface; velocity of solid particle;
ii) the second video camera (shooting in the plane XOZ) aims to
determine the solid particle jumps on which made them at the time they travel
on blind sieve (Fig. 6).

3. Experimental Results
In the processing of experimental data was taken into account: focus
distance, aiming
at the values obtained from the calculation correspond to real
coordinates;
the angle of the plane surface.
So after processing the data obtained with the help of SynthEyes, it could
determine:
A) Solid particle trajectory on the two planes tracked by video cameras
(Fig. 7).
B) Tridimensional trajectory of the solid particle moving on the
oscillating flat surface, obtained by combining the two trajectories previously
presented (Fig. 8);
C) Knowing the time to follow the solid particle on oscillating surface
and the distance traveled of particle after each frame it’s possible to determine
the speed of movement (Fig. 9);
