Aerial-Ground Map Fusion
Aerial-Ground Map Fusion fuses drone-captured aerial images with ground capture data for multi-perspective, multi-scale integrated modeling. It more comprehensively restores the spatial structure and detail of large complex models, improving the completeness and realism of 3D models.
Workflow
Upload Ground and Aerial Data
- Ground Data: Upload data files captured by L series or PortalCam devices. The interface displays the corresponding device type.
- Aerial Data: Select the folder containing drone-captured images. Note the following when selecting:
- The folder should contain between 100 and 10,000 images.
- Only JPG and JPEG format images are supported.
- Image resolution must be higher than 1024×768, and all images must have consistent resolution.
- For PortalCam devices, you need to upload aerial photos and takeoff/landing point photo folders at the corresponding aerial-ground fusion points (if no aerial-ground fusion point was marked at the drone takeoff/landing point during capture, uploading aerial photos directly may result in reduced aerial-ground fusion quality or reconstruction failure).
Note:
- Up to 10 ground data segments are supported, and the total ground data duration must not exceed 200 min.
- The number of drone photos must not exceed 10,000.
Drone RTK Data Toggle
v2.2.0 adds a drone RTK data toggle to control whether to use RTK data recorded by the drone during reconstruction.
- On (default): The system will use the drone's RTK data in reconstruction.
- Off: The drone's RTK data is completely ignored during reconstruction.

Recommended Combinations
The following combinations lower hardware requirements and are recommended:
| Ground Data | Drone Data | Description |
|---|---|---|
| L series RTK | Drone RTK | Recommended, highest accuracy |
| P series aerial-ground fusion control points | Drone RTK | Recommended |
| P series aerial-ground fusion control points | Drone without RTK | Recommended, lowers the drone hardware barrier, supports consumer-grade drones |
Not Recommended Combination
The following combination may cause reconstruction failure or layer separation in the model. Please avoid using it:
| Ground Data | Drone Data | Risk |
|---|---|---|
| L series RTK | Drone without RTK | ⚠️ May cause reconstruction failure or layer separation |
Usage Tips
- P series devices: You can reconstruct without drone RTK (turn off the drone RTK data toggle). Combined with aerial-ground fusion control points, this yields good results.
- L series devices: It is recommended to keep ground RTK + drone RTK (turn on the drone RTK data toggle) to improve reconstruction success rate.
