@Michael :

Thanks for your advice.
(3) have the same light intensity in all of the image (currently, it gets much darker towards the back).

I will take more precaution with my footage.
Put the camera directly above the belt. I will probably process only the center region of the picture since the shadow in the back is getting the region much darker.
(2) have the background as dark as possible (block light that would illuminate background objects below the grid)
I unfortunately can't change the background.

(1) with light from left and right only, you should be able to eliminate the reflections on the grid

That's interesting ! Is there any particular good way to install the light from left/right to avoid reflections ?

Thanks again !
