On my last tutorial, we explored how to control a Pan/Tilt Servo device in order to position a PiCam. Now we will use our device to help the camera to automatically tracking color objects…
This is my first experience with OpenCV and I must confess, I am in love with this fantastic “Open Source Computer Vision Library”.
OpenCV is free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and, Android. On my series of OpenCV tutorials, we will be focusing on Raspberry Pi (so, Raspbian as OS) and Python. OpenCV was designed for computational efficiency and with a strong focus on real-time applications. So, it’s perfect for Physical computing projects!
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.
