Reliability of Pixy Camera?

[nardavin]

Our team is considering purchasing a Pixy camera (link below) to hopefully use in next year's game. For the teams that have used a Pixy in the past, how reliable has it been? As it uses hue-based filtering, have any teams had problems tracking greyscale objects (such as the 2016 boulders)?

Also, after reading through the docs it looks like the get x, y locations are pixel-based. This seems like it may be an issue as the camera appears to have a fairly fish-eye lens (see photo linked below). Has this been an issue for any teams that do vision tracking by using vector-based calculations and moving by gryo angle rather than direct camera feedback?
