Face recognition is an exciting field of computer vision with many possible applications to hardware and devices. Using embedded platforms like the Raspberry Pi and open source computer vision libraries like OpenCV, you can now add face recognition to your own maker projects! In this project I’ll show you how to build a treasure box which unlocks itself using face recognition running on a Raspberry Pi.
Before you get started with this project, it will help to familiarize yourself with a few things:
• If you haven’t setup or used a Raspberry Pi, go through the tutorials on learning the Raspberry Pi like preparing an SD card, network setup, and using SSH before attempting this project. Also take a look at the lesson on using a servo for more background on how servos work.
• Skim the OpenCV tutorial on face recognition for an idea of how face recognition algorithms work. Don’t worry, you don’t need to fully understand the math or code to build and learn from this project.
Continue on to learn about the hardware needed to build this project.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
