What is drone photogrammetry?

What is drone photogrammetry?

In short, drone photogrammetry uses a drone to capture a large number of two-dimensional images over a geographic area and compiles them into accurate three-dimensional terrain models and orthomosaic maps with specialized photogrammetry software. 

3D terrain model of drone photogrammetry

More than just a collection of photographs, drone photogrammetry makes it possible to see the same ground point from different angles and altitudes. From there, you can easily create a 3D map that includes a range of useful visual cues, such as color and texture. 

Photogrammetry first originated in surveillance and reconnaissance and has been used for 170 years. During World War I, pilots combined photography with manned flights to gather intelligence from behind enemy lines. 

Without context, photographs alone were of little value, so these pioneers used local landmarks and landscape features to determine the direction of objects in images. 

In the decades that followed, these practices would be evolved with the appearance of new tools, from stratospheric U2 aircraft to advanced weather satellites to modern drone photogrammetry.

Today's photogrammetric maps are constructed using advanced GIS software to produce surveyor-level measurements of landscapes and infrastructure. These maps are detailed enough to provide valuable insight into environmental conditions in the field.

How does drone photogrammetry work?

How does drone photogrammetry work?

Drone photogrammetry is a two-stage process, including image capture and image processing.

Image capture: The first step is to capture the images needed for the project. This can be done with a still camera or video camera mounted on a drone. The 3D modeling drone will capture a large number of high-resolution photos of an area that overlaps each other to make the same point on the ground visible from different angles and elevations.

Image processing: The aerial photos are then processed manually or using photogrammetry software, which combines or “stitches” the images into a single high-resolution orthomosaic aerial map and 3D models. Photogrammetry software corrects for distortions in the camera sensor and lens as well as errors caused by variations in the terrain, resulting in high-quality maps and 3D models.

Factors to consider when choosing a photogrammetry drone

Factors to consider when choosing a photogrammetry drone

When selecting a photogrammetry drone, several key factors should be carefully considered to ensure optimal performance and suitability for your specific needs. Let's explore these factors in detail:

Flight time

The flight time of a drone is crucial as it determines how long it can remain airborne to capture data. Look for a drone with the longest flight time, typically exceeding 20 minutes, to ensure sufficient coverage of larger areas without frequent battery swaps. Consider factors like battery capacity, power management efficiency, and the weight of the additional payload.

Transmission range

The transmission range refers to the maximum distance at which the drone can communicate with the remote controller or ground station. Opt for long-range drones, preferably over 2 kilometers, to maintain a stable and reliable connection, especially when operating in remote or challenging environments.

Quality of the drone's camera

The camera's quality plays a vital role in capturing high-resolution images for photogrammetry. Assess the following parameters:

Dynamic range: Look for a camera with a wide dynamic range that can handle scenes with varying lighting conditions. This ensures that details in both bright and dark areas are properly captured, resulting in accurate and visually pleasing photogrammetric outputs.

Quality of the drone's camera

Lens quality: Opt for a drone with a high-quality lens that minimizes distortions, aberrations, and vignetting. A well-designed lens reduces image distortion and captures sharp and clear images, enhancing the accuracy of the photogrammetric process.

Global shutter vs. rolling shutter: Global shutter cameras capture images simultaneously across the entire sensor, minimizing motion artifacts and improving accuracy. In contrast, rolling shutter cameras capture images line by line, potentially introducing distortions in fast-moving scenarios. Prefer drones with global shutter cameras for precise and artifact-free results.

Aperture: The aperture determines the amount of light entering the camera and affects image sharpness and depth of field. Opt for drones with adjustable apertures or wide fixed apertures (e.g., f/2.8 or lower) to accommodate various lighting conditions and achieve optimal image quality.

Photogrammetry accuracy

Accuracy is crucial in photogrammetry. Evaluate the drone's positioning system, such as GPS or GNSS, and its accuracy specifications. Look for drones that offer high positional accuracy, typically expressed in centimeters, to ensure precise georeferencing and measurement accuracy in the final output.

Photogrammetry software compatibility

Ensure that the drone's captured data is compatible with popular photogrammetry software solutions. Check if the drone manufacturer provides integration or compatibility with commonly used software packages for data processing and 3D reconstruction. This compatibility ensures a seamless workflow and the ability to leverage advanced software functionalities for analysis and visualization.


Consider whether real-time positioning accuracy or post-processed accuracy is more important for your project. Real-Time Kinematic (RTK) systems provide instantaneous positioning corrections during flight, while Post-Processed Kinematic (PPK) systems apply corrections after data collection. Choose the system that best suits your specific project requirements and accuracy needs.

Drone types

Evaluate the advantages and limitations of different drone types:

  1. Fixed-wing drones offer longer flight times and larger coverage areas, making them suitable for large-scale mapping projects that require extended flight endurance and efficient coverage.
  2. Multirotor drones provide more flexibility in terms of flight maneuvers, hovering capabilities, and precise data collection. They are ideal for smaller areas or projects that require detailed inspection or close-up imaging.
  3. Hybrid VTOL (Vertical Take-Off and Landing) drones combine the benefits of fixed-wing and multirotor drones. They offer both efficient mapping capabilities and versatile maneuverability, making them suitable for various applications, including surveying, inspection, and mapping of complex terrains.

Photogrammetry vs. LiDAR: which is better?

Photogrammetry vs. LiDAR: which is better?

Although digital photogrammetry is the most used measurement method by drone users around the world, drones with LiDAR technology have been gaining popularity for generating 3D models for a number of commercial applications.

If you want to understand more clearly the difference between photogrammetry and LiDAR, just keep reading!

What is a LiDAR and how does it work?

LiDAR, which stands for Light Detection and Ranging, is a remote sensing technology that has been gradually incorporated into aerial drone mapping for a range of specific applications.

LiDAR point cloud

If aerial photogrammetry is based on the overlay of a large number of 2D aerial images used to generate a 3D model, the LiDAR approach is based on direct measurements. LiDAR uses a high-power laser to emit precise laser pulses at a target object. By measuring the timing and intensity of the returned pulse, it provides a dense cloud of points on the terrain and ground that can be used to generate a 3D model in specific software.

With the development of LiDAR technology, the weight and size of these devices have been reduced significantly, making the LiDAR drone increasingly common.

What are the main differences between drone photogrammetry and LiDAR?

Drone photogrammetry and LiDAR are both technologies capable of producing excellent data results for aerial mapping, however, they differ significantly in their price and applications will depend on many factors that must be evaluated beforehand to make a technical decision.

To give you an idea of how, when, and why to use each method, below you can find the main difference between drone photogrammetry and LiDAR.

Photogrammetry is cheaper than LiDAR

By far the main difference between these two aerial survey methods relates to the cost of acquiring the equipment.

A drone-based LiDAR system can cost you $60,000 or more for the hardware alone, as this equipment is far more expensive than conventional sensors and drones that carry out photogrammetry.

In fact, drone photogrammetry has been developed over the last few years and for a large proportion of the technical applications of drone surveying, you won't find much difference in detail or accuracy between it or the products produced by LiDAR.

This means that although LiDAR is a good option in very specific circumstances, the best option in terms of cost will always be traditional photogrammetry.

LiDAR can see through vegetation

LiDAR can provide high vertical accuracy when conducting aerial surveys in densely vegetated areas. This is because LiDAR emits a large number of laser pulses in the near-infrared spectrum which is able to penetrate dense foliage, directly acquiring high-precision 3D terrain data of the ground surface.

Details of the 3D point cloud model

This makes LiDAR an ideal method for aerial surveys of forestry management. The device has replaced traditional forest inventory methods and has been used to estimate the amount of planted and native forest.

However, drone photogrammetry, as it is a very affordable method and its results are very close to LiDAR, is best suited for sparsely vegetated areas or for projects where 3D modeling of the forest structure is not strictly required.

For this reason, photogrammetry is used to manage volumes and structures in mining and civil construction. In these fields, conventional aerial photogrammetry methods are economically more accessible solutions, producing outputs with the same level of detail and accuracy.

LiDAR can be used in low-light or no-light environments

As they are self-illuminating devices, LiDAR systems can operate in low or no-light environments, and even perform aerial surveys at night.

Photogrammetry, on the contrary, is highly dependent on sunlight and aerial photogrammetry can only be carried out when there is sufficient light and is very sensitive to occlusion.

This can be frustrating when you will not be able to carry out aerial photogrammetry on cloudy overcast days as the clouds will block the sunlight from entering.

Under these circumstances, LiDAR would be the best option, even if they are more expensive equipment. Depending on the extent of the area to be mapped and the financial return these projects will provide, LiDAR systems can be a good long-term investment option.

LiDAR is the most accurate surveying solution

Regarding detail and accuracy, both LiDAR and photogrammetry can provide excellent results for 3D modeling.

While LiDAR systems typically have a higher level of detail. Nowadays, drone photogrammetry methods are producing very similar or even better outputs, which depend largely on the sensor quality, the proper execution of the flight, and the data processing.

LiDAR cannot capture RGB colors

The biggest disadvantage of LiDAR systems in terms of detail is that these systems cannot capture RGB colors and you will not identify the texture characteristics of the mapped area in the 3D model generated by LiDAR.

To overcome this obstacle, 3D models by LiDAR often use fake RGB colors, however, the visual quality is always not as good as the data results generated by drone photogrammetry. If you need a model that is consistent with the visual features, LiDAR will not work.

However, there are already LiDAR drones on the market that combine LiDAR technology and RGB sensors, and while they are a little more expensive than traditional models, it is possible to generate 3D models with true colors.

Tips for improving accuracy in drone photogrammetry

Tips for improving accuracy in drone photogrammetry

Photogrammetry drone workflows can be optimized to improve accuracy in capturing and processing data. Here are some tips:

  • Use ground control points (GCPs): Incorporate ground control points into your survey area. These are physical markers with known coordinates that can be used to improve the accuracy of the photogrammetry output. Collect accurate GPS coordinates for these points and include them in your image capture.

Ground control points

  • Optimize camera settings: Set your camera to manual mode and adjust settings such as aperture, ISO, and shutter speed to achieve consistent exposure and image quality throughout the survey. Avoid using automatic exposure as it can lead to inconsistent results.
  • Overlap and sidelap: Ensure sufficient overlap and sidelap between consecutive images. Overlap ensures proper coverage, while sidelap helps in matching and stitching the images. Aim for 70-80% overlap and 30-40% sidelap for optimal results, but adjust these values based on the specific requirements of your project.
  • Consistent flight altitude: Maintain a consistent flight altitude throughout the survey to ensure consistent ground resolution. Use the appropriate flight planning software or tools to control the drone's altitude accurately.
  • Check weather conditions: Choose suitable weather conditions for your flights. Avoid strong winds, rain, or poor visibility, as they can negatively impact the stability of the drone and the quality of the captured images.
  • Quality control: Perform quality checks on the photogrammetry output. Validate the accuracy of the generated point cloud or 3D model by comparing it with ground control points or other reference data. This step helps identify and rectify any errors or inaccuracies.
