3D photogrammetry with drone and ground equipment combines aerial and terrestrial data to create accurate, detailed 3D models of structures, landscapes, or construction sites. This technique uses a series of overlapping photos taken from different angles, which specialized software processes to generate a 3D point cloud or mesh that represents the object or area.
Drone Images: The drone flies a pre-planned route over the area, capturing high-overlap images. These images cover broad, top-down views and oblique (angled) perspectives.
Ground Images: Ground cameras are positioned around the site, capturing close-up details, particularly of areas that may lack depth or clarity in aerial images.
The captured images are tagged with GPS or RTK data for accurate location, and the ground and aerial images are fed into photogrammetry software.
The software aligns the images based on their overlaps and GPS coordinates, using algorithms to generate a dense point cloud. From this, it creates a 3D mesh and texture map, producing a realistic and accurate model.
The final model can be exported as a 3D file for visualization, measurement, or analysis in CAD or BIM software.
High Detail and Precision: Combining aerial and ground perspectives results in models with finer detail, capturing both large-scale site overviews and intricate, ground-level details.
Improved Accuracy: Ground images help resolve areas that may be distorted or occluded in drone images, improving the model’s accuracy.
Comprehensive Coverage: This dual approach ensures that all critical angles and details are captured, even in areas that are inaccessible by drone alone, like under overhangs, bridges, or dense vegetation.
Real-Time Insights for Construction: Provides construction teams with accurate 3D maps for real-time site analysis, progress tracking, and quality control.
Creating accurate models of construction sites for progress monitoring, planning, and quality control.
Documenting and preserving archaeological sites and historical landmarks in 3D, including detailed textures and geometries.
Developing 3D models of existing buildings and urban environments to plan renovations, extensions, or new developments.
Mapping terrain changes, erosion, or vegetation growth for ecological studies and land management.
In summary, using both drones and ground equipment in 3D photogrammetry allows for comprehensive, detailed, and accurate models. This hybrid approach is invaluable for projects where high accuracy and a mix of large-scale and close-up details are essential.
