Easy to Learn and Perform

One of the great things about drone photogrammetry is that it’s not rocket science, and relatively easy to learn. In fact, my first client project was to fly a hospital campus and provide roof dimensions for the design of a solar installation. I conducted the flight mission with my DJI Phantom 4 Pro, using GS Pro as my flight app and DroneDeploy for processing. All with no formal training other than what I could find online.

Most commonly, for a drone photogrammetry mission, you will fly your drone over the designated area, capturing images every few feet to ensure thorough coverage of the target site. It’s important to note that clients often have specific requirements regarding elevation, overlap, and angle. If they haven’t provided these specifications upfront, don’t hesitate to ask for them. Clear communication with your clients ensures that you deliver the desired results and meet their expectations. By understanding their needs and tailoring your flight plan accordingly, you’ll be able to produce accurate and detailed photogrammetric models that impress your clients.

With the right equipment and software, you too can become proficient in creating high-quality models in no time. The advancements in technology have made it more accessible than ever before, empowering individual drone pilots to provide valuable services to various industries.

Wide Range of Applications

And the possibilities are vast! Whether you’re in real estate, construction, engineering, or even filmmaking and video game development, drone photogrammetry enables us to create topographic surveys, inspect infrastructure, monitor construction progress, generate 3D models for architectural visualization—the list goes on. The ability to capture precise and up-to-date aerial data opens up endless opportunities for individual drone pilots or startups.

Ensuring Accuracy in Drone Photogrammetry

Accurate data is paramount in drone photogrammetry as it directly influences the quality of the final models. To ensure precise results, I employ various methods and techniques throughout my workflow.

Importance of Accurate Data GIS Engineer GCP RTKCapture

Maintaining accuracy in drone photogrammetry is required in order to deliver reliable and trustworthy outputs. Whether it’s creating 3D models, conducting topographic surveys, or measuring stockpile volumes, precision is key. Our clients rely on the accuracy of these models to make informed decisions and drive their projects forward.

Utilizing Ground Control Points (GCPs)

One effective method for achieving accuracy is by using Ground Control Points. Personally I prefer this method based on the value and affordability of the solution. GCPs are physical markers placed strategically on the ground with known, precisely measured coordinates. By capturing GCPs in the drone’s images and referencing them during processing, I can georeference the model, aligning it with real-world coordinates. This significantly enhances the accuracy of the final output.

Harnessing Real-Time Kinematic (RTK) Technology

Another advanced (and more expensive) technique is Real-Time Kinematic (RTK) technology. RTK-enabled drones and ground stations utilize high-precision GPS signals to enhance positional accuracy in real-time. This technology provides centimeter-level accuracy, which, again, is required for accurate surveying and mapping deliverables.

By incorporating GCPs and/or leveraging RTK technology, I can ensure that my drone photogrammetry outputs meet the highest standards of accuracy. This allows me to deliver reliable data that clients can confidently use in their decision-making processes.
