Service Details

Photogrammetry is a passive optical metrology and computer vision methodology that extracts high-fidelity three-dimensional (3D) geometric and scan data from a series of overlapping two-dimensional (2D) photographic images. The process utilizes principles of projective geometry, epipolar geometry, and optical triangulation, where intersecting rays from calibrated camera locations compute discrete scan coordinates. Modern digital photogrammetry relies on Structure-from-Motion (SfM) and Multi-View Stereo (MVS) algorithms to automatically identify keypoint correspondences across images, solve for sensor orientation, and reconstruct dense 3D point clouds, polygonal meshes, and orthomosaics with sub-millimeter scan accuracy.

CORE VALUE DRIVERS & DOMAIN APPLICATIONS OF DIGITAL PHOTOGRAMMETRY:

• Geoscan Mapping & Surveying: Generates high-resolution georeferenced orthomosaics, Digital Surface Models (DSMs), and Digital Elevation Models (DEMs) for volumetric analysis, land-use planning, and large-scale topographic mapping.
• Archaeological & Cultural Heritage Documentation: Delivers sub-millimetre non-invasive scan recording, establishing true-colour digital twins, high-density point clouds, and structural models for non-destructive conservation, virtual curation, and H-BIM integration.
• AEC & Infrastructure Engineering: Accelerates Building Information Modelling (BIM) integration, site progression monitoring, design visualization, and structural deformation analysis across civil and industrial construction projects.
• Aerospace & Automotive Metrology: Facilitates non-contact optical deformation tracking, aerodynamic surface modelling, crash-test dynamic analysis, and sub-millimetre component verification for high-precision manufacturing.
• Forensic Scan Reconstruction: Produces immutable, sub-centimetre accurate 3D scene documentation for ballistics trajectory analysis, vehicle collision reconstruction, and objective virtual courtroom presentations.
