Parameters:
-Added "GridGlobal/MaxNodes=0", "Rtabmap/PublishRAMUsage=false", "Mem/DepthAsMask=true", "Kp/FlannRebalancingFactor=2.0", "Vis/DepthAsMask=true".
-Modified "Kp/DetectorStrategy=6", "Kp/MaxFeatures=500", "Mem/UseOdomFeatures=true", "GFTT/QualityLevel=0.001", "GFTT/MinDistance=3", "RGBD/OptimizeMaxError=1", "RGBD/ProximityPathFilteringRadius=1", "Odom/GuessMotion=true", "Odom/VisKeyFrameThr=150", "OdomF2M/BundleAdjustment=1", "Vis/Iterations=300" if built with g2o, "OdomF2M/BundleAdjustmentMaxFrames=10", "OdomFovis/MinFeaturesForEstimate=20", "OdomORBSLAM2/MapSize=3000", "Reg/RepeatOnce=true", "Vis/PnPRefineIterations=0" if built with g2o, "Vis/CorGuessMatchToProjection=true", "Vis/BundleAdjustment=1" if built with g2o, "Icp/MaxCorrespondenceDistance=0.1", "Icp/PointToPlaneK=5", "Icp/PointToPlaneRadius=1", "Icp/PM=true" if built with libpointmatcher, "Stereo/MaxLevel=5", "Stereo/MinDisparity=0.5".
BayesFilter: optimized prediction matrix update. Use of new argument "ignoreLocalSpaceLoopIds" of Memory::getNeighborsId() to ignore loop closure link by space in prediction update.
CameraThread: Added stereo exposure compensation option.
CameraRGB: Added forceGroundNormalsUp option and added support of ground truth from EuRoC dataset.
Statistics: Added "Memory/RAM_usage/MB".
Transform: Added clone() method to do deep copy.
Graph::importPoses(): EuRoC format support (9).
Rtabmap: Local visual loop closures are now identified as GlobalClosure link type.
OccupancyGrid/OctoMap: updated how cache is used (old node retrieved can be re-added to map without re-assembling the whole map).
OdometryF2F: when using ICP, increasing correspondence distance for first two frames. If Vis/CorType=1 and registration fails, second guess without motion is done with Vis/CorType=0.
OdometryF2M/RegVis: updated how features are removed from the map, using new projectedIDs filled in RegistrationInfo by RegistrationVis.
OdometryORBSLAM2: Maximum size of the feature map can be set with "OdomORBSLAM2/MapSize" parameter.
CloudViewer: fixed opengl camera drifting in follow mode.
DatabaseViewer: Added optimization scale option. ConstraintsView: hide loop closure links if type is ignored in gui parameters.
MainWindow: Support of "GridGlobal/MaxNodes" parameters when updating the maps.
UPlot: don't show ellipses when not in graphics view mode, updated how "random" colors are attributed to curves
Added rtabmap-euroc_dataset tool. Updated rtabmap-kitti_dataset and rtabmap-rgbd_dataset tools.
Added rtabmap-reprocess tool.
Added Feature2D::generateKeypoints3D() for convenience.
Added parameter "Vis/PnPOpenCV2".
Added parameter "Vis/ForwardEstOnly".
Removed OdometryOpticalFlow class, replaced by OdometryF2F (frame-to-frame). To get the same previous OpticalFLow approach, parameter "Vis/CorType" should be set to 1.
Some parameters under group "OdomFlow/..." are now under "Vis/CorFlow...".
In Registration class, add computeTransformationMod() method to modify input signatures.
Added constructor Signature(SensorData) for convenience.
Modified words multimap used with cv::Point3f instead of pcl::PointXYZ to limit the use of PCL headers where they are not really required.
Added Stereo::create() for convenience.
Transform: fixed quaternion constructor where data_ was not initialized. Added parentheses operator for convenience.
DatabaseViewer: loading .rtabmap/rtabmap.ini instead of .rtabmap/dbViewer.ini when used from rtabmap application. Added vertical layout option for convenience.
MainWindow: fixed wrong Odometry speed values
ParametersToolBox: using QStackedWidget instead of a QToolBox for space, added "Restore Defaults" button.
Added graph::importPoses().
Can now have a ground truth published with SensorData (filled optionally by CameraImages classes).
Increased database closing time performance when the database is not saved.
Added ParametersToolBox widget in DatabaseViewer for core parameters (refactoring done to make easy access to all rtabmap parameters in DatabaseViewer).
Added Parameters::getType(key).
Added Transform::interpolate() to interpolate between two transforms (SLERP)
Updated pf_filter.m and added test_pf_filter.m MATLAB scripts (making easier to compare with a ground truth)
UPlot: can now save all curve data of a figure in one action (see right-click on legend area->"Copy all curve data to clipboard")
