If you’re curious about how engineers transform drone photos into 3D computer models, this blog series is for you.
At Mapware, we offer an all-in-one commercial photogrammetry product for both commercial and government customers. Our parent company, Robotic Services, designs complete geospatial intelligence (GEOINT) solutions customized for both civilian and government clients, like the U.S. Air Force.
We’re writing this series to give you a basic overview of Mapware’s photogrammetry pipeline—the systems engineering term for sequential processes. Each entry will focus on the concepts underlying one of Mapware’s six pipeline steps.
Reading this series won’t grant you a doctorate in computer science or turn you into a practicing photogrammetrist, but it will help you speak the basic language. We at Mapware aim to get steadily more technical over time and may expand upon concepts we introduce here. We want readers to build their domain knowledge alongside us.
Mapware in the Context of Photogrammetry
Photogrammetry is the science and technology of using photographs, LiDAR, and other geospatial measurement techniques to represent the physical world in actionable ways—such as topographic maps, object reconstructions, or 3D digital twins.
Modern photogrammetry is used in the digitization of archaeological sites, buildings, and entire landscapes, as well as in facial recognition, filmmaking, forensic investigations, and sports.
Mapware is a photogrammetry SaaS designed to ingest aerial photographs of a large area (usually taken by drones) and stitch them together into an accurate 3D digital twin that users can explore virtually by panning, rotating, and zooming, as well as toggling between orthomosaic, 3D model, and other data layers.
To accomplish this, Mapware follows a six-step pipeline:
In the next entry in this series, we will discuss the photogrammetry concepts underlying the first step in the pipeline – Keypoint Extraction.
