Pixy or openMV

Projects General Guidance

Hi.

I need to create one color vision system and am not sure what would be better choice.
I saw quite few negative comments regarding pixy but maybe those are just isolated cases....

To make better choice i would like to know :

Pixy / openMV

a.) Can those sensors used in pixy or openMV detect let's say light blue, or light green or any "light" color ?. I mean, how much color in some sample, is enough for positive detection ?

b.) Would pixy or openMV be OK for detecting color samples 80 cm away from some robot base ?

c.) how much of arduino's system consumption will be lost for this vision system ?

d.) am planning to implement one servo board to, so would not this be to much for arduino due ?

Any input is welcome !

Pixy / openMV

With the Pixy you can teach it the colour(s) your interested in and can fine tune the detection hue range. The Camera deals with all of the image processing & colour matching and just returns to the Arduino and array of the x/y chords of a bounding box and the colour number it matched.
Have you seen the demo Videos?

b.) Would pixy or openMV be OK for detecting color samples 80 cm away from some robot base ?
Depends on how well lit the colour is, how big it is and the lens used.

c.) how much of arduino's system consumption will be lost for this vision system ?
Very little for Pixy, I don't think you can run openMV on Arduino.

d.) am planning to implement one servo board to, so would not this be to much for arduino due ?
So just a vision system and a servo board? Probably don't even need a Due for that.
