Hi
I need pixi for line detector robot, but I need it to detect black line from distance of 2 meters which is eyes of our robot .
Is it possible to connect it to another high resolution camera? I had problem with detecting black color not even in line , everywhere.
Is there any way to detect black color with high accuracy? or will you accept customized it ?
Thanks
Hello Babak,
Currently Pixy uses color cues to detect objects. Pixy will have problems detecting a black (or white) object because these objects have no hue. Sorry 
Pixy’s firmware is completely open source, so you might be able to modify the firmware to suit you needs.

You guys should check these posts out. I have given in detail how to use Pixy Camera.

Thanks for your reply Edward.
I could not find how can I change the codes of Pixy or imply my codes which I wrote on OpenCV on Pixy.
DO you have any further plan to improve pixy and enable it to detect black colors?
Hello Babak,
One problem with black is that it is very common in most images. Most shadows are black. So using black as a distinguishing feature for object detctino usually gives you lots of false positives (if that makes sense). Can you describe your application? Perhaps there is another solution we could suggest.
If you want to investigate Pixy’s firmware, you might consider joining the Firmware SDK group:
