Pixy2 CMUcam5

The Pixy2 CMUcam5 is smaller faster and more capable than the original Pixy. Like its predecessor the Pixy2 can learn to detect objects that you teach it just by pressing a button. Additionally the Pixy2 has new algorithms that detect and track lines for use with line-following robots. With these new algorithms you can detect intersections and “road signs” as well. The road signs can tell your robot what to do such as turn left turn right slow down etc. The best part is that the Pixy2 does all of this at 60 frames per second so your robot can be fast too!No need to futz around with tiny wires — the Pixy2 comes with a special cable to plug directly into an Arduino and a USB cable to plug into a Raspberry Pi so you can get started quickly. No Arduino or Raspberry Pi? No problem! The Pixy2 has several interfaces including SPI I2C UART and USB with simple communication protocols so you can get your chosen controller talking to the Pixy2 in short order.The Pixy2 uses a color-based filtering algorithm to detect objects. Color-based filtering methods are popular because they are fast efficient and relatively robust. Pixy2 calculates hue and saturation of each RGB pixel from the image sensor and uses these as the primary filtering parameters. The hue of an object remains largely unchanged with changes in lighting and exposure. Changes in lighting and exposure can frustrate color filtering algorithms causing them to break. Pixy2’s filtering algorithm is robust to lighting and exposure changes.
