Photogrammetry

Photogrammetry is the process of creating accurate 3D models from multiple overlapping 2D photographs. By analyzing images captured from different angles, specialized software identifies common features and calculates camera positions, depth, and spatial relationships. This information is then used to reconstruct the geometry, dimensions, and textures of real-world objects, structures, and landscapes.

The technique can accurately capture everything from small artifacts to large-scale environments, making it a practical and cost-effective alternative to traditional surveying methods. Since it relies on photographs instead of direct physical measurements, photogrammetry is especially useful for documenting inaccessible, hazardous, or complex locations while maintaining high levels of accuracy.

Photogrammetry is widely applied in architecture, construction, engineering, surveying, archaeology, mining, forestry, and cultural heritage preservation. It enables professionals to create digital twins, generate topographic maps, monitor structural changes, calculate volumes, and preserve historical sites and artifacts. By combining realistic visual detail with precise spatial measurements, photogrammetry has become a key technology for modern 3D modeling, mapping, and geospatial analysis.
