3d Scanning from a mobile device for a MVP

I need to create a raw MVP that can 3d scan with high resolution and texture from a mobile device/Lidar (true depth) camera. This has to be optimized for near-field scanning and can create actual measurements. This will need to create a point cloud that can have automated layer extraction and be exported to an STL. You can use existing open-source software that exists to make this work. I just need a raw MVP show the proof of concept which includes an application. All freelancers must sign NDA.
