AliceVision Changelog

Release 2.0.0 (2018.08.09)

Release of the full 3D reconstruction pipeline.

2018.07

  • New Docker images for Centos 7 and Ubuntu 18
  • New "make bundle" for packaging
  • Refactor split sfm / sfmData / sfmDataIO
  • New visibility remapping methods: Push, PullPush
  • Improve texturing quality with better image selection
  • SfM support multiple folders for features and matches
  • PopSiftImageDescriber: no initialization if not used
  • Offline camera tracking improvements
  • Export animated camera ABC
  • Export undistorted images and filter option
  • MeshroomMaya script integration Image Plane
  • Minor fixes in cameraSensors DB search
  • New fallback if no sensor width info available but FocalLengthIn35mmFilm metadata is present
  • ImageMatchingMultiSfM: add “a_a+a_b” option

2018.06

  • SfM Augmentation: lock cameras from the initial reconstruction
  • SfM: Add option in order to disable the cleaning of tracks forks

2018.03

  • Merge the MVS pipeline in the main branch
  • New options for better auto UVs based on geogram (needs reasonable mesh size in input)
  • Use full resolution images in the MVS pipeline: PrepareDenseScene creates full resolution undistorted images, DepthMap computes downscale when loading images and Texturing can be done in full resolution.
  • New depth map fusion with a multi-scale approach (using nanoflann)
  • ImageMatching: Fix conflict if multiple images with the same UID
  • Add SIFT_UPRIGHT as an ImageDescriber

Release 1.0.0 (2018.03.07)

Release of the Structure-From-Motion pipeline.

2018.02

  • Support Raw and Exr input files
  • Texturing: add multithreading / clean iteration over pixels in triangle
  • MVS: use UIDs
  • Major MVS refactoring
  • New Mesh Denoiser and Decimate based on MeshSDFilter
  • Integration of Uncertainty computation step

2018.01

  • Meshing: Remove facets with helper points but limit holes creation
  • Texturing: Don’t modify the topology
  • Meshing: Add an option to keep only the largest facets group
  • cmake: Geogram as a submodule of cmpmvs
  • Update SfM
  • Modify Image Matching
  • SfM Reorientation software
  • Use OpenMP for featureExtraction with a new imageDescriber memory needs estimation
  • Rewrite “Identify the track to triangulate” in triangulateMultiViews_LORANSAC
  • popSIFT directly on floating point images
  • Use relative path for features and matches in SfM
  • Remove cereal dependency
  • Remove static functions in headers
  • MVS: Add namespace per module
  • MVS: Build as dynamic libraries
  • MVS: Remove unneeded intermediate images

2017.12

2017.11

  • New Local Bundle Adjustment to speedup SfM on large scenes
  • Retexturing on an external user mesh with a retopology (no visibility information and support user UVs) with a first visibilities remapping method.
  • Add new images to a previous SfM reconstruction
  • Use OpenImageIO in SfM

2017.10

  • Reduce memory usage on Meshing
