Drone photogrammetry has become essential for professionals in construction, urban planning, and real estate. But with dozens of software options available, choosing the right tool can be overwhelming.
We've tested and compared the leading photogrammetry platforms to help you make an informed decision. Whether you're creating orthophotos for AI building analysis or generating 3D models for BIM integration, this guide covers everything you need to know.
What is Drone Photogrammetry?
Photogrammetry is the science of making measurements from photographs. In the context of drones, it involves capturing overlapping aerial images, processing these images to create accurate 2D maps (orthophotos), generating 3D point clouds and mesh models, and extracting measurements and geographic data.
The quality of your photogrammetry output directly impacts the accuracy of downstream AI analysis, making software selection critical.

Can I use free software for professional work?
OpenDroneMap is capable of professional work, but requires more technical expertise. For client-facing projects, commercial software often provides better reliability and support.
What's the difference between 2D and 3D photogrammetry?
2D photogrammetry creates orthophotos (flat, measurable images), while 3D photogrammetry generates point clouds and mesh models with depth information.
Do I need RTK/PPK for accurate building measurements?
For survey-grade accuracy (sub-5cm), RTK or PPK is recommended. For general building detection and analysis, standard GPS is often sufficient.
How much overlap do I need for good results?
Aim for 70-80% front overlap and 60-70% side overlap. Higher overlap improves accuracy but increases processing time and data volume.
