SensorData can support laser scans CV_32FC6 format (point cloud with normals). Refactored RegistrationICP and updated CloudViewer to show PointNormal data.
Fixed bug with stereo clouds deterioration if decimation is set (CameraModel::scale()).
CameraRGBDImages: Fixed calibration not loaded
Fixed loading ground truth from RGBD-SLAM format
MainWindow: added ground truth paths in CloudViewer and GraphViewer
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")
-Added parameter "Mem/ReduceGraph" with new link type (NeighborMerged)
-DatabaseViewer: add Info panel, fixed empty extracted database when "RGB images" is not checked
-ConsoleWidget: added buffer size and refresh rate options
-DBDriver: new database info getters
-Graph: added reduceGraph() method, added Dijsktra computePath() with links only
-Updated default parameters: RGBD/LocalLoopDetectionSpace=true, RGBD/LinearUpdate=0.1 and RGBD/AngularUpdate=0.1
-Goals are saved with label instead of ID if the target node has a label
-DataRecorder: fixed saving incrementally the database (instead of only at the end)
-MainWindow: When waypoints are used, resend the current goal (1 sec delay) if it has failed setting it
