Silver ball on white background

[fatess]

Hi,

in RoboCup Junior Rescue Line the task is to collect some silver balls inside an area with white floor and walls.
So, is it possible to make the pixy recognize a silver reflective ball on a white backgroud?
Maybe using an ir filter in front of the lens and an ir led near the pixy? So that the ir light would be reflected by the silver balls and detected from the camera.

Hi,

unfortunately Pixy’s algorithm doesn’t recognize grey (silver) objects. It relies on hue for the detection…one thing you could try is shining a colored LED onto the silver ball. Otherwise, I’m not sure what else would work using Pixy.

Hope this helps!

Cheers,
