This project is the implementation for Hackerboxes #24 using OpenCV and Python instead of Processing. I had too much pain trying to get all the right versions of OpenCV, Java, Processing, etc. to work and realized that it was only a few python modules that cleanly installed on my Windows System.
Also, you can 3D print this camera mount to hold the camera on top of the Pan/Tilt mechanism: https://www.thingiverse.com/thing:2683961
Use the installation instructions found here for Python and OpenCV:
I recommend installing Python 2.7 first, then just using pip to install numpy and matplotlib.
You also will need to install pySerial, also via pip.
- Connect everything via USB to your PC (Camera and Arduino)
- Upload the ino file to your Arduino, note the COM port
- Set the serial port and speed in the top of the cap_test.py file
- Start the python script
Note: You cannot have the serial monitor open in Arduino while you are running the python script. Only one app per serial port at a time!
The Servo should exercise itself, the expectation is that 90 degrees is straight up and down, you may need to move the upper U shaped bar on the servo spindle to compensate for this, or you can muck with the code to fix.
After exercising you should see video on screen with a box around the face that is being detected. It should follow you pretty well.
