Anyone seeking an open multiple view geometry library for 3D computer vision and structure from motion
About openMVG
Extend awareness of the power of 3D reconstruction from images and photogrammetry by developing a C++ framework. Simplify reproducible research with easy-to-read and accurate implementation of state of the art and "classic" algorithms. OpenMVG is designed to be easy to read, learn, modify and use. Thanks to its strict test-driven development and samples, the library allows to build trusted larger systems. OpenMVG provides an end-to-end 3D reconstruction from images framework compounded of libraries, binaries, and pipelines. The libraries provide easy access to features like images manipulation, features description and matching, feature tracking, camera models, multiple-view-geometry, robust-estimation, structure-from-motion algorithms, etc. The binaries solve unit tasks that a pipeline could require scene initialization, feature detection & matching and structure-from-motion reconstruction.

AliceVision
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. 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).

3DF Zephyr
3DF Zephyr lets photogrammetry catch on in multiple scenarios fostering different targets and needs by taking advantage of an all-in-one software suite. Our in-house technology is as versatile and user-friendly as possible and it can easily be adapted to the users’ skills. 3DF Zephyr allows performing 3D reconstructions automatically by using pictures and video data taken with any sensor and captured using any acquisition techniques. You can use different cameras, lenses and focal lengths during the same surveying and scanning session. Get the most out of aerial and ground photogrammetry by processing videos, spherical pictures, multispectral and thermal + RGB imagery on a single software platform. 3DF Zephyr is not just photogrammetry: import, register and analyze your laser scan data (native file formats supported).

COLMAP
COLMAP is a general-purpose Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipeline with a graphical and command-line interface. It offers a wide range of features for reconstruction of ordered and unordered image collections. The software is licensed under the new BSD license. The latest source code is available at GitHub. COLMAP builds on top of existing works and when using specific algorithms within COLMAP, please also cite the original authors, as specified in the source code. For convenience, the pre-built binaries for Windows contain both the graphical and command-line interface executables. To start the COLMAP GUI, you can simply double-click the COLMAP.bat batch script or alternatively run it from the Windows command shell or Powershell. The command-line interface is also accessible through this batch script, which automatically sets the necessary library paths. To list the available COLMAP commands, run COLMAP.bat -h in the command shell cmd.exe or in Powershell.

Meshroom
Presentation of the workflow to create a textured mesh from still images in Meshroom. Meshroom is a 3D reconstruction software based on the open source Photogrammetric Computer Vision Framework AliceVision. Improve robustness of sift features extraction on challenging images: update default values, add new filtering and add dsp-sift variation. Improve mesh quality with a new post-processing. Cells empty/full status are filtered by solid angle ratio to favor smoothness. On some distributions (e.g Ubuntu), you may have conflicts between native drivers and mesa drivers, resulting in an empty black window.
