Version 1.3.1: Released 18-JUL-2015

Version 1.3.0: Released 12-JAN-2015

  • Most important changes:
    • Classes in libraries [mrpt-obs] and [mrpt-maps] now belong to new namespaces (mrpt::obs, mrpt::maps) instead of the old mrpt::slam
    • No more using namespaces polute MRPT headers. Errors in user projects missing using namespace XXX that might be formerly masked will now reveal. This is a good thing, though admitedly annoying...
    • New library [mrpt-nav], subsumming the old [mrpt-reactivenav].
    • New library [mrpt-tfest], a refactor of the old [mrpt-scanmatching].
    • Backwards compatible headers have been provided to ease the transition of user code for all those library changes. Warning messages will be shown recommending deprecated replacements.
  • Detailed list of changes:
    • Lib changes:
    • Build System / General changes:
      • Many optimizations in function arguments (value vs ref). Forces ABI incompatibility with previous versions, hence the change to a new minor version number.
      • Updated embedded version of Eigen to 3.2.3
      • Kinect: Dropped support for the CL NUI API, which seems discontinued. Alternatives in use are libfreenect and OpenNI2.
      • libfreenect is now detected in the system and used instead of compiling the embedded copy of it.
      • Embedded copy of libfreenect has been updated to (23/oct/2014). It now supports "Kinect for Windows".
      • More selective linking of .so files to avoid useless dependencies (Fixes #52).
      • (Windows only) MRPT can now be safely built with libusb support (Freenect, Kinect,...) and it will run on systems without libusb installed, by means of /DELAYLOAD linking flags.
      • More unit tests.
    • Changes in classes:
    • BUG FIXES:

Version 1.2.2: Released 12-SEP-2014

  • Changes in apps:
  • New classes:
  • Changes in classes:
    • Consistency in all "laser scan" classes: angular increments between rays are now FOV/(N-1) instead of FOV/N.
    • [mrpt-base]
      • New method mrpt::img::CImage::loadTGA()
      • IMPORTANT: Changed behavior of CSerializable/CObject macros (see bugfix below), introducing the new macros DEFINE_SERIALIZABLE_POST_*. May require changes in user code if serializable classes are defined:
        • Previous version:
          DEFINE_SERIALIZABLE_PRE_*(...)
          class XXX {
          DEFINE_SERIALIZABLE(XXX)
          };
        • Must be changed in this version to:
          DEFINE_SERIALIZABLE_PRE_*(...)
          class XXX {
          DEFINE_SERIALIZABLE(XXX)
          };
          DEFINE_SERIALIZABLE_POST_*(...)
    • [mrpt-hwdrivers]
    • [mrpt-maps]
    • [mrpt-opengl]
      • mrpt::opengl::CWxGLCanvasBase (affects all 3D rendering classes): better handling of internal timers for smoother updates while rendering in multithreading apps.
    • [mrpt-srba]
      • New method to recover the global coordinates graph-slam problem for a RBA map: mrpt::srba::RbaEngine::get_global_graphslam_problem() (see example [MRPT]\samples\srba-examples\srba-tutorials\tutorial-srba-how-to-recover-global-map.cpp)
  • BUG FIXES:
    • mrpt::img::CImage constructor from a matrix crashed.
    • Unit tests: Named semaphores are not tested anymore if it's detected that the kernel version doesn't support them (Fix Debian 758725).
    • mrpt::synch::CSemaphore [Linux]: didn't call sem_unlink().
    • mrpt::gui::CDisplayWindow3D didn't implement get/set FOV.
    • Valgrind: Fixed potential unaligned memory access warning in point clouds.
    • Fix build error with AppleClang 5.1 (Closes #71).
    • mrpt::utils::CClientTCPSocket: Use a connection success check that works on all platforms
    • Important bug fixed regarding a missing dynamic_cast<> in smart pointers casting. See above possible implications in user code. properly (Patch by Joe Burmeister).

Version 1.1.0: Released 22-FEB-2014

  • New apps:
  • New classes:
  • Changes in classes:
  • Deleted classes:
    • mrpt::utils::CEvent, which was actually unimplemented (!)
    • mrpt::hwdrivers::CInterfaceNI845x has been deleted. It didn't offer features enough to justify a class.
  • New examples:
    • [MRPT]/samples/threadsPipe
    • [MRPT]/samples/NIDAQ_test
    • [MRPT]/openNI2_RGBD_demo (by Mariano Jaimez Tarifa)

    • Updated to the latest nanoflann 1.1.7.
    • Updated to Eigen 3.2.0 - (commit)
    • Binary packages for Windows now include .pdb files to help debugging with Visual Studio.
  • BUG FIXES:
    • Fixed potential infinity loop in mrpt::math::make_vector<1,T>()
    • Fixed build error with GCC when experimental parallelization is enabled. (commit)
    • mrpt::reactivenav::CReactiveNavigationSystem complained about missing config variables ROBOTMODEL_TAU & ROBOTMODEL_DELAY, which were removed in MRPT 1.0.2 - (commit)

    • mrpt::topography::geodeticToENU_WGS84() and related functions used a local +Z axis aligned to the line towards the Earth center; now the Z axis points normally to the ellipsoid surface. The difference with the previous behavior is small but may be of a few millimeters for each meter from the reference point. (commit)
    • Potential crash when setting mpPolygon::setPoints() with empty vectors

(commit)

  • mrpt::reactivenav::CReactiveNavigationSystem and mrpt::reactivenav::CReactiveNavigationSystem3D didn't obey the "enableConsoleOutput" constructor flag - (commit)

Version 1.0.0: Released 1-MAR-2013 (SVN 3287)

r3044

  • mrpt::config::CConfigFileBase::write() now has signatures for "uint32_t" and "uint64_t" in both 32 and 64bit builds, instead of relying of the "size_t" type. This was done to fix build errors in some GCC versions under 32bits.
  • mrpt::poses::CPose2D now caches the cos() and sin() of phi, with a huge performance improvement in most common operations.

[mrpt-bayes]

[mrpt-graphs]

[mrpt-gui]

[mrpt-hwdrivers]

[mrpt-maps]

[mrpt-obs]

[mrpt-opengl]

[mrpt-reactivenav]

  • Much code of mrpt::reactivenav classes have undergone a clean-up, slight optimizations and a translation of old Spanish names/comments to English - r2939, r2942, r2958, r3091
  • mrpt::reactivenav::CParameterizedTrajectoryGenerator::CCollisionGrid now has a more maintainable binary serialization format - r2939

  • mrpt::reactivenav::CHolonomicVFF and mrpt::reactivenav::CHolonomicND now have more configurable parameters, loadable from config files. See their documentation.
  • Repulsive forces from obstacles in mrpt::reactivenav::CHolonomicVFF are now automatically normalized wrt the density of the 360deg view of obstacles and forces follow a "1/range" law instead of the old "exp(-range)".
  • Solved a stability issue in C-S paths, in mrpt::reactivenav::CPTG_DiffDrive_CS (By Mariano Jaimez Tarifa) - r3085

[mrpt-scanmatching]

  • mrpt::scanmatching::robustRigidTransformation():
    • Changed behavior not to allow features to appear in duplicated pairings.
    • Added a consistency test to avoid seeding RANSAC with an inconsistent initial model.

[mrpt-slam]

  • mrpt::slam::CMetricMapBuilderICP now does not integrate the small pose changes due to odometry and/or relocalization when considering the distance and angle thresholds. This means that fewer map updates are now done for the same ICP-SLAM parameters, which should lead to "less noisy" maps.

New functions:

New examples:

  • octomap_simple
  • ransac-data-association

Build system:

  • Update to nanoflann 1.1.4 - r2937, r3017
  • Update to Eigen 3.1.2 - r3064
  • MRPT's root "CMakeLists.txt" has undergone a big refactoring and cleanup - r2961
  • Backward compatible "mrpt-core" has been removed as a fake lib for which to search with CMake from user programs - r2961
  • More system libs are detected in Linux (libclang-dev, lib3ds-dev), discarding embedded versions then - r2963 - Closes #17

  • More unit tests:
  • Added new documentation page: environment variables.
  • Removed the build flag "MRPT_BACKCOMPATIB_08X".
  • Fixes for building under Mac OSX: r3181
  • Enable some c++11 features if the compiler supports them - r3273

BUG FIXES:

  • Build: Fixed detection of OpenCV 2.4.2+ installed in the system via CMake config file instead of pkg-config, which seems to be broken. - r3019
  • [mrpt-base] The iterator returned by end() in all MRPT vectors and matrices (based on Eigen) pointed to the last element, not to the (now correct) next position after the last element - r2941
  • [mrpt-base] mrpt::dynamicsize_vector::resize() performed a memory reallocation even if given the current size, due to an inherited behavior from Eigen. It is not the expected behavior, so it has been fixed. - r3003
  • [mrpt-base] Wrong computation of normPDF() values for the multidimensional cases. Closes #46 - r3068
  • [mrpt-base] mrpt::poses::CPoint::asString() confused the 2D and 3D cases (Thanks Cipri!)

  • [mrpt-maps] Fixed saving the correct point colors in mrpt::maps::CColouredPointsMap::savePCDFile() (Thanks Mariano!) - r3090
  • [mrpt-maps] In CPointsMap::computeMatchingWith3D. Fixed matching two 3D point clouds as each correspondence was inserted twice into the output vector. (By Paco) - r3162
  • [mrpt-opengl] Fixed a potential bug: after deserializing an object based on a display-list (most of them), it won't update in the opengl view.
  • [mrpt-reactivenav] Class mrpt::reactivenav::CHolonomicVFF was not exported in Windows DLL's (Thanks Mariano for noticing!).
