Although there are many cameras that can be connected to any computer since they have free drivers, the truth is that Pixy is not a normal camerabut it is a free and intelligent camera. This camera can not only be connected to other devices without any problem or simply store data, but it can recognize colors from images that it records and memorize them and even track those same objects.
Pixy is accompanied by PixyMon, a software that is capable of controlling and storing the data of the Pixy camera so that once the camera is turned off, the computer reloads the data and the objects and colors learned are not lost. In addition, Pixy can be connected not only to a computer but also to boards like Arduino or Raspberry Pi 2 that can function as an auxiliary plate and give autonomy to the Pixy camera.
The developments for this camera have not been long in coming and not only is there special software for known platforms, but basic programs are already circulating on the Net to insert into our Arduino IDE and take it to our Arduino board.
The truth is that the Pixy camera idea It is very useful, since it recognizes colors in the images it takes, something that, together with the motion sensors, can make our projects are very smart with little effort, since we can position colors or objects just by marking them through the PixyMon software.
On the other hand, the price of this camera is not very high, if we take into account devices like Kinect, the price of the Pixy camera is very low, about 82 euros per unit. An affordable price for many and more with the results it can deliver. Even so, we must remember that it is not intelligent at all, once we turn it on, we have to start the PixyMon assistant to regulate the brightness, the colors and store the colors to follow. Something that needs to be done manually for now. In spite of everything, I think the Pixy camera is going to be something revolutionary not only for Free Hardware but for the field of technology, just as Kinect was at the time.
