The image is stunning with an average Ground Sampling Distance (GSD) of 2.31 cm.
Pictured to the right is a sample of the corresponding orthomosaic viewed at 50%. Here is an example of a 3D model I generated using Pix4D ( ). The photogrammetry process is getting very simple with vendors catering to the drone mapping market. Vendors have made it easy to output Digital Terrain Models (DTM), 2D orthomosaic GeoTIFFs, point clouds and 3D models from photos captured with drones. I have used photogrammetry extensively to build interior and exterior environments using many high resolution photographs. The workflow for recreating reality at 100% quality on a 1:1 scale is going to consist of combining multiple technologies and methods. An easy starting point is Photogrammetry, also known as Structure from Motion (SFM), a process of estimating three-dimensional points from a sequence of two-dimensional images. The technology has been around for a number of years and has matured significantly in recent years. There is a number of products and open source tools for capturing reality for digitization on the market. The majority of the commercial products are quite expensive costing well into the tens of thousands of dollars.
The goal is to have a complete interior and exterior of a building as a digital asset that is very high quality and 1:1 scale. Once the digital asset is generated it will be used in many ways, to include game engines and virtual reality environments. I have been working on digitally recreating reality at 1:1 scale.
