The Pixy2 (CMUcam5) is a long awaited followup to the original Pixy .... fully programmable embedded computer vision sensor. The main processor is the NXP LPC4330 32bit dual core ARM processor connected to an Aptina MT9M114 image sensor, 1296×976 resolution with integrated image flow processor. The following video gives a great overview of the Pixy2's new capabilities ....
New features added to the PIXY2 include:
Pixy2 detects lines, intersections and small barcodes, intended for line-following robots
Improved framerate – 60 frames-per-second
Tracking algorithms have been added to color-based object detection
Improved and simplified libraries for Arduino, Raspberry Pi and other controllers
Integrated light source
as well as the features previously available within the Pixy, the main features being:
Small, fast, easy-to-use, low-cost, readily-available vision system
Learns to detect objects that you teach it
Connects to Arduino with included cable. Also works with Raspberry Pi, BeagleBone and similar - controllers
All libraries for Arduino, Raspberry Pi, etc. are provided
C/C++ and Python are supported
Communicates via one of several interfaces: SPI, I2C, UART, USB or analog/digital output
Configuration utility runs on Windows, MacOS and Linux
All software/firmware is open-source GNU-licensed
All hardware documentation including schematics, bill of materials, PCB layout, etc. are provided.
The Pixy2 now includes line tracking and can read 4-bit bar codes ....
