PHOTOGRAMMETRY PIPELINE

Photogrammetry is the science of making measurements from photographs. It infers
the geometry of a scene from a set of unordered photographies or videos.
Photography is the projection of a 3D scene onto a 2D plane, losing depth
information. The goal of photogrammetry is to reverse this process.

The dense modeling of the scene is the result yielded by chaining two computer
vision-based pipelines:
“Structure-from-Motion” (SfM) and “Multi View Stereo” (MVS).

Learn more about each step of the photogrammetry pipeline.

MESHROOM SOFTWARE


PHOTOGRAMMETRY WORKFLOW

 * High Quality 3D Models
 * Use GPUs to combine High Quality with Performance
 * Scalable solution (>1K Images)
 * Nodal Editor with Caching Mechanism
 * Augment a solved Structure-From-Motion with new images




POST-PROCESSING AND RETEXTURING

 * Decimate your mesh
 * Retexture your mesh in Meshroom after retopology in Blender, ZBrush, Maya,
   ...
 * Use Custom UVs or automatically generate them




HDR PANORAMA WORKFLOW

 * Fusion of Multi-bracketing LDR images into HDR
 * Alignment of panorama images
 * Support for fisheye optics
 * Automatically estimate fisheye circle or manually edit it
 * Take advantage of motorized-head file




RENDER FARM SUBMISSION

 * Easy to integrate in your Renderfarm System
 * Add specific rules to select the most suitable machines regarding CPU, RAM,
   GPU requirements of each Node




CUSTOM PIPELINES

 * You can create custom pipelines and use it as a default template
 * It is a fully Open Source nodal workflow, so you can enter into the code and
   customize some steps to specific needs without re-creating a full pipeline
 * Contact us for specific customizations

OPEN SOURCE

We build a fully integrated software for 3D reconstruction, photomodeling and
camera tracking. We aim to provide a strong software basis with state-of-the-art
computer vision algorithms that can be tested, analyzed and reused. Links
between academia and industry is a requirement to provide cutting-edge
algorithms with the robustness and the quality required all along the visual
effects and shooting process.

This open approach enables both us and other users to achieve a high degree of
integration and easy customisation for any studio pipeline.

Beyond our project objectives, open source is a way of life. We love to exchange
ideas, improve ourselves while making improvements for other people and discover
new collaboration opportunities to expand everybody’s horizon.
