Photogrammetry Overview

AI Photogrammetry leverages advanced algorithms to convert captured photos into detailed, feature-rich 3D models. On the way to a perfect 3D model, you can select the optimal processing mode (algorithm) based on the object type, its background and capture method.

AI algorithm without masks

For static small- to medium-sized objects standing on a stable background that does not change during capture, and that you photographed/recorded by walking around them (including close-ups), the AI algorithm without masks will deliver the best results.

This mode (where the Extract object from background option in Advanced settings is disabled) also performs best for objects with poor monotonous textures in static environments.

AI algorithm with masks

If the object was rotated (e.g., on a turntable), flipped, or moved to different positions during capture, or if the background was inconsistent or moving; and you did not take close-ups (i.e., maintained roughly the same distance from the object), we recommend using the AI algorithm with masks. You can use it by enabling the Extract object from background checkbox in Advanced settings. This mode will automatically separate the object from the background and produces a clean model. It is generally recommended for textured objects, especially if captured from multiple orientations. For best results, keep the full object within the camera’s field of view.

Note

This mode is most suitable for small to medium-sized objects.

Classic (non-AI) algorithm

For large objects or highly detailed scenes such as landscapes, use the Classic algorithm.

Note

We recommend using this algorithm for drone data sets.

How It Works

The process begins by importing a set of photos into Artec Studio and creating a preview where the images are positioned in 3D space, producing a Photo scan object for further processing. Next, a triangular mesh is generated using specialized algorithms based on the scene type. This mesh can be processed and textured within Artec Studio Lite, allowing users to create accurate and visually rich 3D representations, making 3D modeling accessible to everyone without the need for a 3D scanner.
