3D Mapping & Modeling
What is Photogrammetry?
Photogrammetry is a cutting-edge technology that enables the creation of highly detailed 3D models and maps of physical objects and environments using aerial photography. By using specialized cameras mounted on drones, we can capture high-resolution images of a site or object from multiple angles, which are then processed and analyzed using sophisticated software to create detailed, accurate 3D models and maps. This technology has a wide range of applications, including land surveying, architecture, construction, and industrial inspection.
If you're looking for a fast, cost-effective, and highly accurate way to map and measure your site, photogrammetry is the solution you need.
How Aerial 3D Point Cloud and Mesh Models are created.
The RPAS (drone) camera will capture hundreds, even thousands of overlapping photos of the ground, structure point of Interest. The The 3D map or 3D model is then created using aerial image stitching algorithms. The RPAS will fly using autonomous programmed flight paths called waypoints and take photos at a specified intervals.
Each photo captured will also have its GPS coordinates (Geotag) saved, which also assists to build the 3D map. A geotagged photograph is associated with a geographical location. This is done by assigning at least a latitude and longitude to the image. This can then be placed in Google Earth/Maps for viewing.
What we can deliver...
Drone images are corrected for image distortion and stitched together during post-processing to create a highly-accurate orthomosaic map. File formats: GeoTIFF (.tiff), .jpg, .png, Google tiles (.kml, .html)
Precise Area Measurements
High resolution orthographic photographs you make highly-accurate distance and area measurements.
Stockpile Volumetric Measurements
With 3D mapping software, it is also possible to obtain volumetric measurements from the images.
Digital Surface and Terrain Models (DSM, DTM)
Drone images can also be used to create DSM and DTM models of the area. File formats: GeoTiff (.tif), .xyz, .las, .laz
3D textured mesh
The 3D textured mesh is a reproduction of the edges, faces, vertices and texture of the area shot by the drone. This model is most useful for visual inspection or for when external stakeholders or public involvement is essential for a project. File formats: .ply, .fbx, .dxf, .obj, .pdf
