Abstract:

This project allows a minimalist 3D scan (taking multiple pictures, recording camera position, using opendrone map to rebuild the 3D scene) with the house faces (accessible/visible faces) then load it as 3D model and export the data back on MapMint for 3D viewing.

The state of the art BEFORE GSoC:

Have you ever wished that you could easily transfer a real object into a digital file? The technology is here, but most of us simply do not have access to high-end 3D scanners that can reconstruct the digital geometry of a physical model.

The added value:

Now it is possible to take multiple pictures using MapMint4ME, then visualize the 3D model issued from the taken pictures in MapMint.

Future Work:

• One challenging part of my project, not yet done, is to get to link the MapMint4ME with a MapMint instance.
• I did not get enough time to automate the step of creating the model using openDroneMap, here is what i was thinking to do.

Documentation

My work consist of three parts:

• One graphical image describing my project:

Part One: Get the pictures using MapMint4ME

Here are the commits for this part.

• Created a button that direct you to the this layout.
• I have created a form that can be filled with a fixed number of images taken from the mobile MapMint4ME app, and will be transfered to MapMint, here is how to do it.
• I have some issues regarding linking MapMint to MapMint4ME, so I did get the datasets for buildings from here, and I have taken the tajjin pictures by myself.

Part Two: Create the 3D model using ODM

• I have created a 3D model from pictures, here is the tutorial.

Part Three: Visualize the 3D model in MapMint

Here are the commits for this part.

• Got MapMint working on virtual machine tutorial here, then I finished up with configuring it on Docker tutorial here.
• Added 3D models to the volume see here.
• Used docker volumes to get access to the 3D models to be visualized.
• Using threeJS, I was able to render the 3D models in MapMint, using a template.
