Photogrammetry

2 min. read

Photogrammetry is the process of creating 3D models or maps from 2D photographs. It involves analyzing overlapping images to extract geometric information and reconstruct the objects or terrain in 3D space

Introduction to Photogrammetry

Photogrammetry is the science of making measurements and calculations from photographs. It is a powerful tool used to obtain accurate and precise information about objects, scenes and terrain captured in 2D images.

By analyzing the geometric relationship between multiple photographs taken from different viewpoints, photogrammetry can reconstruct a three-dimensional (3D) model or map of the scene.

This technology has a wide range of applications, including topographic mapping, engineering surveys, architecture, archaeology, and even film and game production.

The advancements in image capture technology and software have made photogrammetry a valuable tool for industries and researchers alike, providing a cost-effective and efficient method for collecting data and generating high-resolution 3D models.

Photogrammetry in Video Games

Unreal Engine is probably the best use case of Photogrammetry in games.

Other AAA games like Resident Evil 2 (Remake) also uses Photogrammetry for most of the game.
