Demystifying Photogrammetry: Bringing Real-World Objects to Life

Photogrammetry is the remarkable process of creating accurate 3D models of real-life objects, people, structures, or ' environments using a multitude of photographs. Let's dive into how this fascinating technique works. The term "photogrammetry" derives from the Greek words "phōtos" meaning "light," "grámma" meaning "drawing," and "métron" meaning "measurement." In essence, photogrammetry involves measuring and simulating objects through photography.

Demystifying Photogrammetry: Bringing Real-World Objects to Life

According to the comprehensive definition provided by our trusty friend Wikipedia:

"Photogrammetry is the art, science, and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena."

According to the comprehensive definition provided by our trusty friend Wikipedia:

But what happens behind the scenes without delving into complex scientific concepts? Here's a simplified breakdown:

By capturing a large volume of photographs from various angles, we reconstruct the environment virtually, generating a 3D model. For instance, in the video example, we utilized approximately 800 pictures taken manually. It's crucial to obtain sufficient levels of detail, depending on the desired model. We scan and analyze the pictures, ultimately constructing a 3D model based on a point cloud.

But what happens behind the scenes without delving into complex scientific concepts? Here's a simplified breakdown:

Simply move your phone or AR-compatible device, and you can explore the virtual environment while the engine and hardware track your location and movements.
