This is one of the most amazing things I have done lately:
We needed a 3D model of our house with outdoor areas to plan the further progress. An architect friend brought his Phantom 4 drone and flew around the house (automatically) and took about 120 photos (on a cloudy day to avoid hard shadows) from 40 meteres height. These were uploaded to Memento and a few hours later the model was downloaded and converted to obj and brought in to Rhino in 1:1 scale in mm with an amazing accuracy. (I am not connected to Memento in any way)
As you can see it captured a lot of details.
