What Are Photogrammetry Tools?
Photogrammetry tools are software applications designed to transform photos into accurate 3D models. These models are widely used for tasks like analysis, planning, and documentation.
What is Photogrammetry?
"Photogrammetry is the art and science of extracting 3D information from photographs." – Autodesk
The process starts with capturing overlapping images of an object, structure, or space. By identifying shared features in these images, the software calculates real-world 3D coordinates using triangulation. Often, this process includes georeferencing, which ensures the data aligns correctly with the Earth's surface.
One of photogrammetry's standout benefits is its ability to create detailed digital replicas of physical spaces. This capability is especially useful for industrial site management. Construction managers, infrastructure teams, and facility managers rely on these 3D models for tasks like asset management, tracking project progress, planning for safety, and spatial analysis. Understanding this foundational process helps highlight the differences between free and paid photogrammetry tools.
