How to Make a Drone 3D Model: LiDAR vs. Photogrammetry vs. SLAM

Creating a 3D model with a drone takes three key steps:

Deciding how you’ll capture your 3D model data (in this case, it will be by drone).
Capturing the data that will be turned into the 3D model.
Processing that data using special software

As we mentioned above, the two main methods for creating drone 3D models are with LiDAR or Photogrammetry.

But SLAM is also gaining traction for drone 3D modeling. SLAM uses onboard sensors-such as cameras or LiDAR-to simultaneously map an environment and track the drone’s position within it, making it ideal for mapping areas where GPS is unavailable, such as indoors, underground, or in dense forests.

Cost	High	Moderate to low	Varies (depends on sensors and software)

Choosing the Right Method for Your Drone 3D Model

The choice between LiDAR and Photogrammetry depends largely on your project’s requirements:

Use LiDAR if: You need high precision, are working in dense vegetation, or need to map large areas or complex terrain.
Use Photogrammetry if: You’re focusing on surface textures, need detailed models of buildings or structures, or are working in environments with clear weather and controlled lighting.
Use SLAM if: You need real-time mapping, are working indoors, in GPS-denied environments (like tunnels or dense forests), or require adaptive navigation for fast-changing or cluttered spaces

What Is LiDAR?

LiDAR is a technology that uses laser pulses to measure distances to objects and create highly accurate 3D point clouds. LiDAR works by emitting light in the form of laser beams, which bounce off objects and return to the sensor, enabling precise distance measurements. These measurements are then used to map the topography of the environment, capturing details such as terrain, vegetation, and structures.

LiDAR is ideal for projects where high precision is required, especially in difficult environments like dense vegetation, low-light conditions, or complex terrain. It’s widely used in industries like forestry and large-scale terrain mapping, where accurate, detailed models are crucial for decision-making and planning.

What Is Photogrammetry?

Photogrammetry is the process of creating 3D models by capturing high-resolution images from a drone and using specialized software to convert those images into a 3D model. Photogrammetry works by overlapping multiple photos taken from different angles, allowing the software to calculate the distances between key points to generate a three-dimensional representation.

This method is excellent for capturing detailed surface textures, such as those found in buildings, urban environments, and agriculture. It’s commonly used for tasks that require intricate detail, like building modeling, landscape mapping, and analyzing the texture and features of objects or surfaces.

What Is SLAM?

SLAM (Simultaneous Localization and Mapping) is a cutting-edge technology that enables drones to create a map of an unknown environment while simultaneously tracking their own position within that map. Unlike traditional mapping methods that rely on GPS or require extensive post-processing, SLAM allows for real-time 3D mapping and autonomous navigation-even in GPS-denied environments such as tunnels, dense forests, or indoor spaces.

SLAM works by fusing data from various onboard sensors-such as LiDAR, cameras, and inertial measurement units (IMUs)-to continuously scan the surroundings and update both the map and the drone’s location as it moves. This process enables the drone to adapt to dynamic environments, avoid obstacles, and deliver accurate 3D models on the fly.

SLAM is ideal for applications where instant results and navigation without GPS are critical. It is widely used for indoor inspections, underground exploration, disaster response, and mapping complex or confined spaces. By providing real-time situational awareness and high-precision mapping, SLAM is transforming how drones are used across industries like construction, infrastructure assessment, mining, and emergency response.

How To Make A Drone 3D Model with Photogrammetry

Getting the Right Data for Your Drone 3D Model

Aerial photogrammetry works by measuring the same subject from multiple perspectives to create an accurate 3D model through triangulation.

The more photos you take, the more data you’ll have to generate a precise model.

Considerations for setting up your automated survey flight:

Ensure a 60-70% overlap between images to allow for accurate triangulation.
Fly your drone at an altitude of 150ft to 200ft for optimal straight-down images.
Capture images from a high altitude (30º camera angle) to get wide coverage of the subject.
Lower your altitude to a middle range (45º camera angle) for better detail.
Use a low altitude (70º camera angle) to capture fine details and close-up views.
Adjust your radius to keep the subject in frame at all times.

Tips for Photogrammetry Data Collection

Here are some practical tips to improve your photogrammetry data collection:

Ensure sufficient image overlap (60-70%) for accurate triangulation and model generation.
Capture photos from various angles to ensure comprehensive coverage of the subject.
Double-check your camera settings before flying, especially aperture, shutter speed, and white balance, to ensure optimal lighting and exposure.
Maintain consistent flight altitudes to avoid scale discrepancies between images.
If surveying large areas, use a grid flight pattern to ensure no areas are missed.

Processing Photogrammetry Data into a 3D Model

Once you’ve collected the imagery, follow these steps to process the data into a 3D model:

Upload your images to photogrammetry software like Pix4Dmapper or Agisoft Metashape to stitch them together into a 3D point cloud.
Georeference the point cloud with your ground control points (GCPs) to ensure accurate scaling and location within real-world coordinates.
Optimize the 3D model in the software, adjusting texture, meshing, and other parameters for clarity and detail.
Export the model in the desired format (e.g., .obj, .fbx) for further analysis or integration into other platforms.

How to Make a Drone 3D Models with LiDAR

To create a drone 3D model using LiDAR technology, you need to collect accurate and comprehensive data that can be processed into a detailed 3D model. Here’s how to gather the data required to create a high-quality LiDAR drone 3D model:

Get a drone with LiDAR capability. LiDAR-equipped drones like the DJI Matrice 350 RTK or Flyability’s Elios 3 are commonly used for high-precision mapping and modeling. These drones are equipped with LiDAR sensors that emit laser pulses to measure distances and create 3D point clouds of the environment.
Set your ground control points (GCPs). GCPs are crucial for georeferencing the LiDAR data, ensuring accurate scale and alignment. These points are placed on the ground and have known geographic coordinates. Make sure to distribute these GCPs throughout the area you are surveying to minimize errors and improve the overall accuracy of the 3D model.
Plan your flight mission. Set up your drone to fly at the appropriate altitude, typically between 100 and 200 meters, depending on the resolution you require. Ensure your drone is set to cover the survey area systematically, with flight paths that overlap slightly to improve data accuracy. The LiDAR sensor should be calibrated for the proper settings, such as scanning frequency and laser intensity.
Choose the right weather and environmental conditions. Like other aerial surveys, it’s best to perform the LiDAR survey in clear weather conditions. Avoid flying in rainy, foggy, or windy conditions that could interfere with the quality of the data. Ideal conditions include dry, clear days with minimal wind.
Process your LiDAR data in specialized software. Once you’ve gathered the data, you’ll need to process it into a 3D model using specialized software. Popular platforms for LiDAR processing include Autodesk ReCap, Pix4Dmapper, or Bentley ContextCapture. These programs help you turn raw LiDAR data into a usable 3D point cloud, which can then be meshed to create a detailed 3D model of the area or structure.

Getting the Right Data for Your Drone 3D Model Using LiDAR

LiDAR works by emitting laser pulses and measuring the time it takes for them to return to the sensor, creating a dense point cloud of data that represents the physical surface of the scanned environment. To achieve the best results, follow these considerations when setting up your LiDAR survey:

Ensure adequate point density—higher point density provides more detailed and accurate 3D models. Aim for a minimum of 8-12 points per square meter for high-resolution data.
Flight height should be adjusted based on the level of detail needed. For larger areas, a higher altitude is acceptable, but for smaller, more detailed scans, a lower flight height is preferred.
Overlap between flight lines is critical. A 30% overlap between adjacent passes helps ensure continuous coverage and more precise point cloud alignment.
Use proper LiDAR sensor settings, including scan frequency and pulse rate. Make sure the settings are optimized for the type of terrain you are scanning (e.g., forests, urban areas, or open fields).
Monitor GPS accuracy to ensure that the LiDAR data is correctly georeferenced, especially for large areas or when precise measurements are critical.

Tips for LiDAR Data Collection

Here are some helpful tips to improve your LiDAR data collection process:

Fly the drone in a grid pattern to ensure full coverage of the target area. Adjust flight paths based on the terrain and ensure overlap for better point cloud generation.
Make sure the drone’s LiDAR sensor is properly calibrated before every mission to avoid inaccuracies in the data.
For complex environments, such as densely forested areas, consider using multiple flight passes at different altitudes to capture a complete dataset.
Check the data quality during the flight. If you notice any gaps or discrepancies, adjust the flight path in real-time to capture missing data.

Processing LiDAR Data into a 3D Model

Once you have collected the LiDAR data, the next step is to process the point cloud into a 3D model using specialized software. This typically involves:

Importing the LiDAR point cloud data into software like Autodesk ReCap or Pix4Dmapper, where the data is cleaned, filtered, and transformed into a 3D mesh.
Georeferencing the point cloud data using the ground control points (GCPs) you set up earlier, ensuring the model is scaled correctly and aligned to real-world coordinates.
Optimizing the mesh for visualization or further analysis, including adding textures or merging point clouds from different passes to create a complete model.
Exporting the 3D model into a file format (e.g., .obj, .fbx, or .las) that can be used for further analysis, visualization, or integration into other digital platforms.

How to Make a Drone 3D Model with SLAM

To create a 3D model using SLAM (Simultaneous Localization and Mapping), you’ll use a drone equipped with sensors like LiDAR or cameras and specialized SLAM software that generates a 3D map in real time-even in GPS-denied environments such as indoors, underground, or in complex industrial sites.

Here’s how to gather and process data for a high-quality SLAM-based drone 3D model:

Choose a drone with SLAM capability. Select a drone equipped with SLAM-compatible sensors, such as the Flyability Elios 3 or a similar model with onboard LiDAR or stereo cameras. These drones are specifically designed for indoor or GPS-denied mapping and real-time 3D modeling.
Plan your mission and configure your sensors. Before flying, set up your SLAM system by calibrating the sensors and configuring the mapping parameters in the SLAM software. Unlike traditional photogrammetry or LiDAR mapping, SLAM does not require ground control points (GCPs), but you should ensure the environment is safe and accessible for the drone.
Fly the drone and capture data in real time. Operate the drone manually or with assisted navigation, allowing it to explore and scan the environment. As the drone flies, the SLAM system will simultaneously build a 3D map and track the drone’s position, updating the model in real time. For best results, fly slowly and steadily, and ensure all areas of interest are scanned from multiple angles.
Monitor the mapping progress live. Use the SLAM software’s live visualization to check for coverage gaps or areas needing more detail. If necessary, adjust your flight path or revisit sections to ensure a complete dataset.
Export and refine your 3D model. Once the mission is complete, export the 3D map or point cloud from the SLAM software. You can further process or clean the model in specialized 3D editing or point cloud software, and export it in formats like .las, .obj, or .ply for analysis, visualization, or integration into other workflows.

Getting the Right Data for Your Drone 3D Model Using SLAM

SLAM works by continuously fusing sensor data-such as LiDAR scans or camera images-with inertial measurements to build an accurate 3D map as the drone moves. The key to high-quality SLAM mapping is thorough coverage: fly slowly, avoid abrupt movements, and ensure you scan all surfaces from multiple angles to minimize blind spots.

Tips for SLAM Data Collection

Fly at a steady speed and maintain a clear line of sight to avoid losing tracking or missing areas.
Scan complex environments from different perspectives to capture all surfaces and features.
Use the live map view to identify and revisit missed sections during the flight.
Avoid sudden movements or rapid changes in direction, which can disrupt SLAM tracking.
Ensure your sensors are clean and properly calibrated before each mission.

Processing SLAM Data into a 3D Model
