Pixy CMUcam5 Sensor
Page 2 of 4
Description
introduction:
Pixy is a fast vision sensor you can quickly “teach” to find objects, and it connects directly to
Arduino and other controllers.
Pixy addresses two problems: 1) image sensors output lots of data, dozens of megabytes per
second; 2) processing this of data can overwhelm many processors; by pairing a powerful
dedicated processor with the image sensor. Pixy processes images from the image sensor
and only sends the useful information to your microcontroller. The information is available
through one of several interfaces: UART serial, SPI, I2C, digital out, or analog out. So your
Arduino or other microcontroller can talk easily with Pixy and still have plenty of CPU available
for other tasks.
It’s possible to hook up multiple Pixys to your microcontroller, for example, a robot with 4
Pixys and 360 degrees of sensing. Or use Pixy without a microcontroller and use the digital or
analog outputs to trigger events, switches, servos, etc.

Features
•
Pixy uses a hue-based color filtering algorithm to detect objects. Pixy calculates the
hue and saturation of each RGB pixel from the image sensor and uses these as the
primary filtering parameters.
•
Pixy remembers up to 7 different color signatures. If you need more than seven, you
can use color codes (see below).
•
Pixy can find literally hundreds of objects at a time.
•
Pixy processed an entire 640x400 image frame every 1/50
th
of a second.
•
You can get a complete update of all detected objects’ positions every 20 ms.
•
Pixy is unique because you can physically teach it what you are interested in sensing.
PixyMon
PixyMon is an application that runs on your PC or Mac. It allows you to see what Pixy sees,
either as raw or processed video. It also allows you to configure your Pixy, set the output port
and manage color signatures. PixyMon communicates with Pixy over a standard mini USB
cable.
What’s
a “color code”?
A color code (CC) is two or more color tags placed close together. Pixy can detect and decode
CCs and present them as special objects. CCs are useful if you have lots of objects you want to
detect and identify (i.e. more than could be detected with the seven separate color signatures
alone).
