KWIVER v1.5.1 Release Notes

This is a patch release of KWIVER that provides fixes over the previous
v1.5.0 release.

Bug Fixes since v1.5.0

Config

  • Add support for Visual Studio 2019 in the setup_KWIVER.bat

Vital

  • Added a missing include file in track.cxx required to build on MSVC 2019.

  • Changed incorrect metadata tag in convert_0601_metadata.cxx from
    KLV_0601_TARGET_LOCATION_LAT to KLV_0601_TARGET_LOCATION_ELEV.

  • Fixed a typo in the TARGET_LOCATION metadata field name.

  • Updated metadata field names for kv::geo_point types to be more
    descriptive. Made the distinction between elevation and altitude.

Arrows: Ceres

  • Fixed a bug in which the update_state_every_iteration config option
    for bundle_adjust was not respected and was always manually overridden with
    "true" if a callback was registered.

Arrows: Core

  • Remove some unnecessary computation in initialize_camera_landmarks_keyframe
    by adding checks to detect earlier when computations that cannot achieve
    their desired result due to insufficient data.

  • Fixed a bug in initialize_cameras_landmarks_keyframe in which the
    principal point was not initialized from the image size unless there
    was also metadata useful for determining focal length. Distortion
    parameters were also not properly preserved in this initialization
    and this has also been resolved.

  • Fixed a bug in initialize_cameras_landmarks_keyframe in which the
    camera estimation loop would sometimes exit early without processing
    the remaining cameras. This is further improved to try the lists of
    remaining cameras multiple times until no further cameras are added.

  • Fixed a bug in initialize_cameras_landmarks_keyframe in which the
    updated landmarks are not returned from a helper function and therefore
    intermediate results are returned as the final output.

  • Fixed a bug in track features that was causing a crash on Linux after
    detecting features on the first frame of video.

Arrows: CUDA

  • Fixed a linking error on Linux with some versions of CUDA requiring
    to "recompile with -fPIC".

  • Fixed a bug in launching the integrate_depth_maps CUDA kernel.
    Previously, the kernel would fail to launch if the size of the volume
    along the X direction was greater than 1024.

  • Added a max_voxels_per_launch configuration option to the CUDA
    integrate_depth_maps algorithm. This works around a CUDA limitation
    in which long-running CUDA kernels cause the GPU to freeze the system.
    On Windows this leads to a time out after 2 seconds and the application
    is terminated. To avoid this we now launch the kernel multiple times
    covering a subset of voxels in each chunk.

Arrows: OpenCV

  • Fixed improper use of RANSAC in the OpenCV estimate_pnp algorithm.
    This algorithm was producing a lower then expected success rate when
    resectioning cameras.

  • Fixed a long standing bug with memory management when converting between
    OpenCV and Vital images. Reference counting was not handled correctly.
    A workaround was previously added that forced a deep copy, but this created
    another bug resulting in images with invalid first_pixel() values.
    Both of these issues have been addressed.

Arrows: Serialize

  • Fixed a bug in the JSON serializer for metadata where bool fields caused a
    runtime error.

  • Fixed a bug in JSON serialization of metadata maps which caused name
    collisions for multiple metadata packets associated the same frame. This
    made the output unusable by applications other than KWIVER.
