Case Studies: Air-Ground Fusion

Real-world scenarios demonstrate why air-ground fusion has become essential for comprehensive 3D reconstruction. The following case studies, drawn from urban planning, cultural heritage preservation, and facility management, illustrate how the integration of aerial and ground-based data sources solves critical coverage gaps that single-platform approaches cannot address.

Case 1: Large-Scale City

Attribute	Detail
Object	30 km² urban area
Aerial Equipment	Five-lens oblique camera
Ground Equipment	R200 SLAM Scanner (processed in batches for nearly three months)
Focus	Ground-level shops & under elevated roads

Result: Complete urban model covering both aerial overview and street-level details, filling coverage gaps under elevated infrastructure.

Case 2: Cultural & Heritage Site

Attribute	Detail
Object	Complex geometry with occlusions, including buildings, courtyards, underground spaces
Advantage	Air-ground fusion captures complete facades, roofs, and interiors
Outcome	Consistent results enabling heritage preservation and documentation

Result: Digital preservation of historically significant architecture with interior-exterior continuity.

Case 3: Stadium Digital Twin

Attribute	Detail
Object	Tennis stadium modeled indoor & outdoor
Outdoor Equipment	Drone aerial capture
Indoor Equipment	R200 SLAM Scanner for occluded areas
Application	Merged 3D model used as digital twin base for events & daily management

Result: Complete digital twin enabling facility management, event planning, and operational optimization.
