Release Notes Summary:

  • Texturing: Largely improve the Texturing quality using Multi-Band Blending technique. PR
  • Texturing: Support for RAW image files: Libraw update and fix its usage in OpenImageIO (fix color shift and use correct gamma). PR
  • Texturing: Performance optimization by iterating over multiple output textures at the same time. PR
  • Texturing: Add support for UDIM in UV mapping and use it by default. PR
  • Meshing: Export the dense point cloud in Alembic and computes the points colors PR.
  • Meshing: New option to export the full raw dense point cloud in the Meshing software (with all 3D points candidates before cut and filtering). PR
  • Meshing: Adds an option to export color data per vertex and MeshFiltering correctly preserves colors. PR.
  • HDR: New HDR module for the fusion of multiple LDR images with the corresponding new software LDR2HDR. It implements linear fusion as well as Camera Response Function (CRF) calibration with Robertson, Debevec or Grossberg methods. PR
  • PrepareDenseScene: Add experimental option to correct Exposure Values (EV) of input images to uniformize dataset exposures. PR
  • FeatureExtraction: Include CCTag in the release binaries both on Linux and Windows. PR

Full Release Notes:

  • DepthMap: Bug fix if no nearby cameras (a big bottleneck of the release 2019.1). PR
  • DepthMap: Bug fix: missing allocation when reducing the number of planes. PR
  • DepthMap: Bug fix: SGM early stop condition could provide an unallocated buffer to the refine step PR
  • FeatureExtraction: Bug fix in AKAZE filtering (sort keypoints by size before grid filtering). PR

Release 2.1.0 (2019.01.30)

Release Notes Summary:

  • More complete sensor database and better matching as well as explicit status for lens initialization
  • Add support for rig of cameras. This enables to add more contraints if you make acquisition with multiple synchronized devices.
  • Support for reconstruction with projected light patterns and texturing with another images set.
  • Better estimation of the space to reconstruct to limit the reconstruction zone. This avoid to reconstruct low quality and useless areas around the main object/environment.
  • New option to directly mesh the SfM results. This provides a quick solution to get a draft mesh (without cuda requirement).
  • Reduce IO and intermediate files in MVS part of the pipeline.

Full Release Notes:

  • sensorDB: Update the sensors database with much more models
  • sensorDB: Use FocalLengthIn35mmFilm metadata as a fallback if available
  • sensorDB: Improve matching of metadata make/model with sensor database
  • CameraInit: New management of intrinsics (serial number, error/warning log) with an explicit InstrinsicInitMode enum
  • CameraInit: Fix intrinsics grouping with serial number as expected and add metadata "AliceVision::SensorWidth" (or "AliceVision::SensorWidthEstimated" if estimated from FocalLength/FocalLengthIn35mmFilm)
  • CameraInit: Explicit warning if serial number is missing
  • SfM: Add support for rig of cameras. This information is used as a new constraint in the SfM. This option can now be combined with localBA. You need to use a specific folder hierarchy in the input images files (for instance: “/my/dataset/rig/0/DSLR_0001.JPG”, “/my/dataset/rig/1/DSLR_0001.JPG”) to provide this information.
  • PrepareDenseScene: New imagesFolders option to override input images. This enables to use images with light patterns projected for SfM and MVS parts and do the Texturing with another set of images.
  • Meshing fusion: New option to use SfM landmarks (mesh from sparse point cloud) or combine them with depth maps
  • Meshing: Add option estimateSpaceFromSfM to better estimate the bounding box of the reconstruction and avoid useless reconstruction of the environment
  • MVS: Reduce IO and intermediate files. Use sfmData in the MVS pipeline (instead of MVS seeds, ini file) and do not export depthmap files before refine
  • ExportAnimatedCamera: Improved solution to export an SfM result into an animated camera
  • PrepareDenseScene: Remove hackish software CameraConnection (now properly done in PrepareDenseScene)
  • PrepareDenseScene: Allow parallelization on renderfarm
  • FeatureExtraction: Add grid filtering in AKAZE (to avoid unmanageable number of keypoints on well textured images)
  • DepthMap: Fix memory leak in SGMVolume
  • Meshing: Fix loading of OBJ with normals
  • System: Improve gpu detection and logging
  • DepthMap: Enable usage of multiple GPUs by default with an option to add a limit
  • DepthMap: Fuse estimate & refine in a single loop (fuse “computeDepthMapsPSSGM” with “refineDepthMaps”) and use the same image cache
  • DepthMap: Remove depthMapInfo files and use image metadata instead
  • DepthMap: Initial refactoring for better readability to prepare the optimization work
  • SfM: Refactoring of localBA (now fused with the standard BA code to avoid redundancy)
  • ConvertSfMFormat: Users can now specify a view whitelist to filter views
  • SfM: The user can provide only one image of the initial pair and it will choose the 2nd image automatically. This allows to ensure that the reconstruction start from a specific part of the scene without choosing the image pair manually.
  • SfMTransform: Allow to choose one view as the origin for the coordinate system
  • SfM Augmentation from known poses: When the sfm starts with existing cameras poses but without landmarks, it now does the triangulation first.
  • LightingEstimation: New module with preliminary low-level methods for lighting estimation (spherical harmonics)
  • MeshDenoising: Fix ignored parameter denoising outer iteration
  • Meshing: Bug fix (infinity loop) in Meshing when the BBox is empty
  • SfM LocalBA: reduce minimum number of images to use sparse BA (change threshold from 100 to 20) to speedup large reconstructions when localBA is used.
  • Minor build fix for compatibility with ceres 2.

  • Sort features and matches
  • FeatureExtraction: Limit the number of features per image with grid filtering to ensure good repartition
  • New software to align reconstructions based on common cameras (using UID)
