What is Photogrammetry?

Drones are often used to captures images for photogrammetry.  But what is Photogrammetry and why do people us it?

Photogrammetry is the process of creating 3D models of objects or scenes from photographs. It's like piecing together a jigsaw puzzle, but instead of using flat pieces of cardboard, you're using images from different angles to build a digital representation of the real world.

Here are the basic steps involved in photogrammetry:

  1. Capture images: You take multiple photos of the object or scene you want to model, from different angles and distances. The more photos you take, the more detail you'll be able to capture in your 3D model.
  2. Process the images: Special software is used to identify common features in the photos, such as corners, edges, and textures. These features are used to create a point cloud, which is a collection of 3D points that represent the surface of the object.
  3. Reconstruct the 3D model: The software uses the point cloud to create a mesh, which is a network of triangles that defines the shape of the object. The software then adds textures to the mesh, which are based on the colors and patterns in the original photos.

Photogrammetry has a wide range of applications, including:

    • Architecture and engineering: Photogrammetry can be used to create 3D models of buildings, bridges, and other structures. These models can be used for a variety of purposes, such as planning renovations, inspecting for damage, and creating virtual tours.
    • Archaeology and cultural heritage: Photogrammetry can be used to document and preserve historical sites and artifacts. This can help to protect these objects from damage and make them more accessible to the public.
    • Visual effects and animation: Photogrammetry is used to create realistic 3D models of people, animals, and objects for use in movies, TV shows, and video games.
    • Product design and manufacturing: Photogrammetry can be used to create 3D models of products for use in design, prototyping, and manufacturing.

Photogrammetry is a powerful tool that can be used for a variety of purposes. It is a versatile technology that is constantly evolving, and it is likely to play an even greater role in the future.
