Detailed Description

Hybrid tracker based on moving-edges and keypoints tracked using KLT tracker.

Warning: This class is only available if OpenCV is installed, and used.

The tracker requires the knowledge of the 3D model that could be provided in a vrml or in a cao file. The cao format is described in loadCAOModel(). It may also use an xml file used to tune the behavior of the tracker and an init file used to compute the pose at the very first image.

The following code shows the simplest way to use the tracker. The Tutorial: Model-based tracking is also a good starting point to use this class.

#include <visp/vpMbEdgeKltTracker.h>
#include <visp/vpImage.h>
#include <visp/vpImageIo.h>
#include <visp/vpHomogeneousMatrix.h>
#include <visp/vpCameraParameters.h>
#include <visp/vpException.h>
#include <visp/vpDisplayX.h>
int main()
{
#if defined VISP_HAVE_OPENCV
  vpMbEdgeKltTracker tracker; // Create an hybrid model based tracker.
  vpImage<unsigned char> I;
  vpHomogeneousMatrix cMo; // Pose computed using the tracker.
  vpCameraParameters cam;
  // Acquire an image
  vpImageIo::read(I, "cube.pgm");
#if defined VISP_HAVE_X11
  vpDisplayX display;
  display.init(I,100,100,"Mb Hybrid Tracker");
#endif
#if defined VISP_HAVE_XML2
  tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
#endif
  tracker.getCameraParameters(cam);   // Get the camera parameters used by the tracker (from the configuration file).
  tracker.loadModel("cube.cao");      // Load the 3d model in cao format. No 3rd party library is required
  tracker.initClick(I, "cube.init");  // Initialise manually the pose by clicking on the image points associated to the 3d points contained in the cube.init file.
  while(true){
    // Acquire a new image
    vpDisplay::display(I);
    tracker.track(I);     // Track the object on this image
    tracker.getPose(cMo); // Get the pose
    tracker.display(I, cMo, cam, vpColor::darkRed, 1); // Display the model at the computed pose.
    vpDisplay::flush(I);
  }
#if defined VISP_HAVE_XML2
  // Cleanup memory allocated by xml library used to parse the xml config file in vpMbEdgeKltTracker::loadConfigFile()
  vpXmlParser::cleanup();
#endif
  return 0;
#endif
}

The tracker can also be used without display, in that case the initial pose must be known (object always at the same initial pose for example) or computed using another method:

#include <visp/vpMbEdgeKltTracker.h>
#include <visp/vpImage.h>
#include <visp/vpHomogeneousMatrix.h>
#include <visp/vpCameraParameters.h>
#include <visp/vpImageIo.h>
int main()
{
#if defined VISP_HAVE_OPENCV
  vpMbEdgeKltTracker tracker; // Create an hybrid model based tracker.
  vpImage<unsigned char> I;
  vpHomogeneousMatrix cMo; // Pose used in entry (has to be defined), then computed using the tracker. 
  
  //acquire an image
  vpImageIo::read(I, "cube.pgm"); // Example of acquisition
#if defined VISP_HAVE_XML2
  tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
#endif
  tracker.loadModel("cube.cao"); // load the 3d model, to read .wrl model coin is required, if coin is not installed .cao file can be used.
  tracker.initFromPose(I, cMo); // initialise the tracker with the given pose.
  while(true){
    // acquire a new image
    tracker.track(I); // track the object on this image
    tracker.getPose(cMo); // get the pose 
  }
  
#if defined VISP_HAVE_XML2
  // Cleanup memory allocated by xml library used to parse the xml config file in vpMbEdgeKltTracker::loadConfigFile()
  vpXmlParser::cleanup();
#endif
  return 0;
#endif
}

Finally it can be used not to track an object but just to display a model at a given pose:

#include <visp/vpMbEdgeKltTracker.h>
#include <visp/vpImage.h>
#include <visp/vpImageIo.h>
#include <visp/vpHomogeneousMatrix.h>
#include <visp/vpCameraParameters.h>
#include <visp/vpDisplayX.h>
int main()
{
#if defined VISP_HAVE_OPENCV
  vpMbEdgeKltTracker tracker; // Create an hybrid model based tracker.
  vpImage<unsigned char> I;
  vpHomogeneousMatrix cMo; // Pose used to display the model. 
  vpCameraParameters cam;
  
  // Acquire an image
  vpImageIo::read(I, "cube.pgm");
  
#if defined VISP_HAVE_X11
  vpDisplayX display;
  display.init(I,100,100,"Mb Hybrid Tracker");
#endif
#if defined VISP_HAVE_XML2
  tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
#endif
  tracker.getCameraParameters(cam); // Get the camera parameters used by the tracker (from the configuration file).
  tracker.loadModel("cube.cao"); // load the 3d model, to read .wrl model coin is required, if coin is not installed .cao file can be used.
  while(true){
    // acquire a new image
    // Get the pose using any method
    vpDisplay::display(I);
    tracker.display(I, cMo, cam, vpColor::darkRed, 1, true); // Display the model at the computed pose.
    vpDisplay::flush(I);
  }
  
#endif
  // Cleanup memory allocated by xml library used to parse the xml config file in vpMbEdgeKltTracker::loadConfigFile()
  vpXmlParser::cleanup();
#endif
  return 0;
#endif
}

protectedinherited

Compute the pyramid of image associated to the image in parameter. The scales computed are the ones corresponding to the scales attribute of the class. If OpenCV is detected, the functions used to computed a smoothed pyramid come from OpenCV, otherwise a simple subsampling (no smoothing, no interpolation) is realized.

Warning: The pyramid contains pointers to vpImage. To properly deallocate the pyramid. All the element but the first (which is a pointer to the input image) must be freed. A proper cleaning is implemented in the cleanPyramid() method.

Parameters

void vpMbTracker::loadVRMLModel ( const std::string & modelFile )

protectedvirtualinherited

Load the 3D model of the object from a vrml file. Only LineSet and FaceSet are extracted from the vrml file.

int main()

#endif

}; The cylinders extracted using this method do not use the Cylinder keyword of vrml since vrml exporter such as Blender or AC3D consider a cylinder as an IndexedFaceSet. To test whether an indexedFaceSet is a cylinder or not, the name of the geometry is read. If the name begins with "cyl" then the faceset is supposed to be a cylinder. For example, the line
geometry DEF cyl_cylinder1 IndexedFaceSet

defines a cylinder named cyl_cylinder1.

Exceptions

vpException::fatalError if the file cannot be open.

Parameters

Deprecated:: Since this function name is not explicit, use rather setGoodMovingEdgesRatioThreshold() that does the same. Set the first threshold used to check if the tracking failed. It corresponds to the percentage of good point which is necessary.

The condition which has to be be satisfied is the following : $nbGoodPoint > threshold1 \times (nbGoodPoint + nbBadPoint)$ .

void vpMbEdgeTracker::setGoodMovingEdgesRatioThreshold ( const double threshold )

inlineinherited

Set the threshold value between 0 and 1 over good moving edges ratio. It allows to decide if the tracker has enough valid moving edges to compute a pose. 1 means that all moving edges should be considered as good to have a valid pose, while 0.1 means that 10% of the moving edge are enough to declare a pose valid.

Parameters

If the file is not set then, the initClick() method will create a .0.pos file in the root directory. This directory is the path to the file given to the method initClick() used to know the coordinates in the object frame.

Parameters

filename : The new filename.

Definition at line 463 of file vpMbTracker.h.

void vpMbEdgeTracker::setScales ( const std::vector< bool > & scale )

inherited

Set the scales to use to realize the tracking. The vector of boolean activates or not the scales to set for the object tracking. The first element of the list correspond to the tracking on the full image, the second element corresponds to the tracking on an image subsampled by two.

Using multi scale tracking allows to track the object with greater moves. It requires the computation of a pyramid of images, but the total tracking can be faster than a tracking based only on the full scale. The pose is computed from the smallest image to the biggest. This may be dangerous if the object to track is small in the image, because the subsampled scale(s) will have only few points to compute the pose (it could result in a loss of precision).

Warning: This method must be used before the tracker has been initialized ( before the call of the loadConfigFile() or loadModel() methods).; At least one level must be activated.

Parameters

scale : The vector describing the levels to use.
