Software 

In order to convert a 2D Image to 3D tactile display we built a software pipeline that creates a height map. Below are the steps of our pipeline.

We created a Depth Map of the Great Wave Image using Deep Neural Networks.

We used Canny Edge Detection to create a contour image of Great Wave using Image Processing

We combined the Depth Map and Contour Image to create a  3D Model stl file. We then print that with the 3D printer.

 

With this process we are also able to create a height map. Then we sent the height map to the Arduino via bluetooth.

Finally, the Arduino uses the pin information (height map) to figure out which. pins to raise and displays the Great Wave on our tactile display.
