3D Terrain Models from Imagery
Reconstructs 3D terrain with buildings, relief, roads, and vegetation from satellite and other imagery combined with geodata. Models of selected areas support calculations, simulations, and visualizations.
The task
Produce three-dimensional models of selected territories for calculations, simulations and visualizations, automating terrain construction from imagery and geodata.
Building the terrain
We developed a system for processing open geodata, satellite and aerial imagery. Our own trained models reconstruct buildings, roofs, roads and vegetation.
The terrain includes relief, object geometry, heights, materials and lighting by time of day. Forest and vegetation cover is generated as a separate layer.
Computational and interactive environment
The models are used for analysis of insolation, shadows and visibility, and of vehicle and pedestrian flows. Roads, railway lines and pipelines can be traced across the terrain.
The interactive environment supports real-time flyovers of the area and its use in training autonomous vehicles. The same process can be applied to new areas using whatever source data is available.
