hello,
would it be possible for the pixy to recognize numbers on a rotating wheel (gas counter).
at least the exact value is not important but recognizing one each time the wheel turn is important,
thanks
Hi Emmanuel,
Pixy does not have any computer vision code to recognize digits, if that’s what you’re asking. It can recognize colored objects of your choosing, so maybe there is a way for you to add color to the rotating numbers. Or, if you’re up for it, you could write the digit recognition code yourself and integrate it with Pixy’s firmware.
If you make each digit a different color, then it would be almost trivial to recognize when the number wheel rotates.

Hello scott,
In fact I don’t have access to the wheel so clearly an issue to me and I don’t need the value, just recognizing one in 10 (0-9) would be sufficient for me…
I guess making a simple pattern recognition would be low level code ? would the pixie have an advantage in this compared to another simpler webcam ?
thanks,
Emmanuel
Hi Emmanuel,
Pixy works best on objects with color, so if you’re unable to incorporate color in to this wheel then you may have to find another solution. Others on this forum have discussed modifying Pixy’s color algorithm to work on black and white objects instead of color. This may be an option for you if you’re willing to modify the source code.
