How to create 3D models (Digital twins) with drones for reporting.
Drone Data Collection Methods
To build accurate digital twins, you need high-quality data collected by drones. Achieving this requires drones equipped with advanced sensors and carefully planned flights to ensure reliable 3D models.
Types of Data Drones Capture
Modern drones are equipped with cutting-edge sensors that gather a variety of data types essential for creating digital twins. With multi-sensor payloads, drones can simultaneously collect different datasets, making them invaluable for comprehensive modeling projects.
Aerial imagery and video are the foundation of most 3D modeling efforts. Drones with RGB cameras capture high-resolution images from multiple angles and altitudes, which are then processed through photogrammetry to create detailed reconstructions of surfaces, textures, and structural elements.
For even greater precision, LiDAR sensors use laser pulses to measure distances. This technology is particularly effective for mapping complex geometries and can even penetrate vegetation to reveal terrain features underneath. It’s a game-changer for industrial sites with intricate layouts or challenging environments.
Thermal imaging adds another layer of insight by detecting temperature variations. This data is especially useful for monitoring equipment performance, spotting potential issues, and enabling predictive maintenance. For example, thermal sensors can identify heat signatures pointing to electrical faults, insulation failures, or mechanical wear before they escalate into major problems.
Additionally, drones can capture topographical information and 3D mapping datasets, providing a broader spatial context. With a single flight, drones can map entire sites, create topographical maps, and safely access areas that would be dangerous or unreachable for ground teams.
A great example of this technology in action comes from Paper Airplane, which used DJI drones and Dronelink flight control software to create a digital twin of the Oklahoma District Court House and Federal Judicial Learning Center and Museum in February 2024. The automated flight features ensured efficient and safe data collection, surpassing client expectations.
These diverse data collection methods pave the way for precise flight planning, which is key to producing high-fidelity digital twins.
Flight Planning and Data Collection Best Practices
Effective drone data collection starts with meticulous preparation. Flight planning ensures images are captured at consistent altitudes with proper overlap, leading to reliable and accurate results. The difference between amateur and professional outcomes often lies in the attention to detail during the planning phase.
Mark Buie and Mark Barker, Product Engineers from the ArcGIS Drone2Map Team, emphasize the importance of overlap:
"When planning a mission, start with 80 percent overlap and 80 percent sidelap to ensure good coverage of your project area and maximize the accuracy of your products."
They advise against dropping below 70% overlap and 65% sidelap, as insufficient coverage can lead to gaps or inaccuracies in the final model.
Environmental factors also play a critical role. Consistent lighting is essential for capturing high-quality images. Scheduling flights around solar noon, when the sun is at its highest, minimizes shadows and glare that could interfere with photogrammetry.
Flight speed and camera settings require careful adjustments. Flying at slower speeds reduces motion blur, while fine-tuning camera settings ensures optimal exposure. For balanced detail and coverage, capturing nadir imagery at altitudes between 150–200 feet (45–60 meters) is recommended.
For projects demanding high accuracy, Ground Control Points (GCPs) are indispensable. These precisely surveyed reference points should be distributed evenly across the area in a triangular grid pattern to ensure accurate georeferencing of the 3D model.
An experienced operator shared a practical tip on the DroneDeploy Forum in July 2017. MichaelLLeader used two 45-degree POI oblique flights to model structures. For a building with a 100-foot longest horizontal dimension, the first flight was conducted at a 150-foot radius and 150 feet high, while the second flight used a 100-foot radius at 50 feet high. This approach produced high-quality LAS files compatible with Autodesk software for rendering 3D models.
Finally, data quality control is crucial. Reviewing and removing problematic images - such as those that are blurry, overexposed, or contain too much of the horizon - can significantly improve processing results and the accuracy of the final model.

Converting Drone Data into 3D Models
Transforming raw drone data into precise 3D models involves the use of photogrammetry and thorough quality control measures.
Step-by-Step 3D Model Creation Process
Turning drone imagery into a 3D model relies on photogrammetry, which uses overlapping photos taken from various angles to generate detailed 3D reconstructions. Advanced photogrammetry tools, such as Pix4D, DroneDeploy, DJI Terra, or Agisoft Metashape, streamline this process.
Here’s how it works:
- Image Import and Feature Matching: Upload your drone-captured images into the software. The program identifies shared features across photos and applies Structure From Motion (SFM) to create a sparse point cloud while determining camera positions.
- Georeferencing: Ground Control Points (GCPs) collected during the drone flight ensure the model is positioned accurately in its real-world context.
- Depth Map and 3D Mesh: Depth mapping assigns depth values to each pixel, converting the sparse point cloud into a detailed, textured 3D mesh.
- Data Integration for Complex Models: For advanced projects, additional data types like thermal imaging, LiDAR scans, and orthomosaics can be incorporated into a unified model.
This process, when executed carefully, produces models that are precise enough for applications like digital twins, which replicate real-world environments digitally.
Quality Control and Accuracy Checks
Achieving reliable 3D models hinges on rigorous quality control throughout the workflow. The difference between a dependable digital twin and an inaccurate model often lies in the attention to detail during validation and accuracy checks.
Start by ensuring that flight parameters, such as Ground Sampling Distance (GSD) and image overlap, align with the project’s requirements. Review image quality - checking for proper exposure, sharpness, and color consistency - to avoid errors that could compromise the final model.
Geometric accuracy is another critical factor. Validate Ground Control Points by comparing their processed coordinates with surveyed reference points to detect inconsistencies. Multi-angle image coverage is also essential. For instance, Hammer Missions’ in-house tests at "The Mill" showed that combining nadir (straight-down) and oblique (angled) shots with sufficient overlap significantly improves model quality.
Additional quality checks include:
- Point Cloud Density: Ensuring enough detail in the point cloud for accurate modeling.
- Texture Quality: Verifying the clarity of photographic details in the model.
- Dimensional Accuracy: Comparing the model’s measurements with real-world dimensions to identify potential errors.
Hardware advancements can also boost quality. For example, the DJI Mavic 3 Enterprise, equipped with a 4/3-inch sensor and 20MP camera, captures high-resolution images and completes site mapping twice as fast as the Mavic 2 Pro, while maintaining superior results.
