Is i t possible to use pixy for general image processing? What I really want is to be able to have pixy take a picture and then have my software be able to access the image line by line, pixel by pixel. Pixy has solved the basic problem for me for contrast and the overall imaging. And of course since libraries exist for the arduino and raspberry PI I’m halfway there. But I’m not trying to track objects, just find and locate one object with irregular dimensions. If I can get the image line by line the processing I have to do is easy but I dont know how to access the image. Is it possible? Any ideas?
Thanks,
Joel
Hello Joel,
Getting raw images over one of the serial ports (I2C, UART, SPI) will be fairly slow, and it’s not supported with the current firmware. You can do this with libpixyusb over USB. This thread might be of interest to you:

What platform are you using to communicate with Pixy?

I was using an Arduino mega but I am wondering if I need more umph and have to use something else. What I am trying to do is create an array of points of a saw teeth of a saw blade passing in front of the camera. THe actual image isn’t a problem. the blade is shiny and the background can be black. It’s getting the point array which is at the fringes of what I know about image processing (nearly nothing) I will read through all the links and see if I can make sense of it. Much Thanks to Edward and Ramanathan for their timely replies.

Hello Joel,
Sounds interesting! Is this a power saw? Hopefully the saw teeth aren’t moving at 4000 RPM like a table saw!

Edward,
Handsaws actually - an not while in use, while we set and file the teeth one by one. if I can electronically determine the exact position of the saw teeth using visual inspection I can sharpen any kind of saw and I don’t need fancy fixturing.
thanks,
joel
Sounds cool!
