Raspberry Pi opens a lot of possibilities for do-it-yourself projects. It’s affordable and full of potential for implementing challenging projects. After having spent several years tinkering around my 3D printer, wanting to build my own 3D scanner to complete the 3D workflow was an exciting idea. Using MATLAB and the Raspberry Pi hardware support package for development made the experiment quick and easy, at least from the software perspective.
In this project, I decided to use one of the most basic scanning techniques – focusing more on getting the entire mechanism to work with off-the-shelf components rather than get the best possible results. Raspberry Pi serves as the main controller board for the setup, capturing the images using the Pi Camera, controlling the Line LASER diode and providing control signals to the EasyDriver (Stepper Motor Driver). I have used MATLAB and the Raspberry Pi Hardware support package to implement the algorithm and deploy it to the Raspberry Pi. This step helped me reduce the time required to setup the controller board, and allowed me to focus on getting the mathematics behind the scanning algorithm correct.
