Efficient 3D Artifact Modeling in the Field: A Simplified Photogrammetry Approach

Abstract

Photogrammetry is a 3D scanning technique that uses a series of 2D photos to create a virtual 3D model of an object. This technique involves measuring and analyzing features from multiple photographs, with photogrammetry software combining these to generate a detailed 3D model. The photogrammetry process is intricate and demands a certain level of expertise to accurately scan an object in 3D. It typically requires manual photography from various angles, with the object needing proper lighting to ensure quality results. While the process can be executed with multiple cameras, this approach can be costly. To simplify and automate photogrammetry, a specialized device called a photogrammetry rig has been developed. This rig automates the photogrammetry process by placing the object on a turntable. The device rotates the object at predefined angles while a camera captures a series of images. After completing one full rotation, the camera shifts to a new angle and the process continues. The captured images are then uploaded to software, which processes them into a high-quality 3D model. By automating the photogrammetry process, this rig makes 3D scanning more accessible and affordable, allowing users to obtain high-quality scans of various objects without requiring specialized knowledge. This technology has broad applications across numerous fields globally.
