Line tracking, white line on yellowish background


#1

Good day!

First of all I would like to say that the Pixy2 cam is such a great product, and its line-tracking algorithm helps me save so much of time. However I’m having a problem with tracking a white line on yellowish background. Is there a way I can tweak the settings or the filter?

Thanks!!

Hello,
The line algorithm doesn’t use color information, only contrast. White on yellow is going to be hard for Pixy. You can try to adjust the “edge threshold” though:

Increasing “line filtering” might also help:

but it will slow things down somewhat.

Hope this helps :slight_smile:
