Detailed Description

Make the complete tracking of an object by using its CAD model.

Warning
This class is deprecated for user usage. You should rather use the high level vpMbGenericTracker class.

This class allows to track an object or a scene given its 3D model. A video can be found on YouTube https://www.youtube.com/watch?v=UK10KMMJFCI The Tutorial: Markerless model-based tracking (deprecated) is also a good starting point to use this class.

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.

If you are interested in using a MBT tracker in your applications, you may have a look at:

Deprecated examples
The following code shows the simplest way to use the tracker.

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpHomogeneousMatrix.h>
#include <visp3/core/vpImage.h>
#include <visp3/gui/vpDisplayX.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/mbt/vpMbEdgeTracker.h>
int main()
{
vpMbEdgeTracker tracker; // Create a model based tracker.
vpHomogeneousMatrix cMo; // Pose computed using the tracker.
// Acquire an image
vpImageIo::read(I, "cube.pgm");
#if defined(VISP_HAVE_X11)
display.init(I,100,100,"Mb Edge Tracker");
#endif
tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
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
// Initialise manually the pose by clicking on the image points associated to the 3d points contained in the
// cube.init file.
tracker.initClick(I, "cube.init");
while(true){
// Acquire a new image
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.
}
return 0;
}
Generic class defining intrinsic camera parameters.

Implementation of an homogeneous matrix and operations on such kind of matrices.
static void read(vpImage< unsigned char > &I, const std::string &filename, int backend=IO_DEFAULT_BACKEND)

For application with large inter-images displacement, multi-scale tracking is also possible, by setting the number of scales used and by activating (or not) them using a vector of booleans, as presented in the following code:

...
vpHomogeneousMatrix cMo; // Pose computed using the tracker.
std::vector< bool > scales(3); //Three scales used
scales.push_back(true); //First scale : active
scales.push_back(false); //Second scale (/2) : not active
scales.push_back(true); //Third scale (/4) : active
tracker.setScales(scales); // Set active scales for multi-scale tracking
tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
tracker.getCameraParameters(cam); // Get the camera parameters used by the tracker (from the configuration file).
...
std::vector< bool > scales
Vector of scale level to use for the multi-scale tracking.

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 <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpHomogeneousMatrix.h>
#include <visp3/core/vpImage.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/mbt/vpMbEdgeTracker.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
vpMbEdgeTracker tracker; // Create a model based tracker.
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
tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
// load the 3d model, to read .wrl model coin is required, if coin is not installed .cao file can be used.
tracker.loadModel("cube.cao");
tracker.initFromPose(I, cMo); // initialize 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
}
return 0;
}

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

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpHomogeneousMatrix.h>
#include <visp3/core/vpImage.h>
#include <visp3/gui/vpDisplayX.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/mbt/vpMbEdgeTracker.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
vpMbEdgeTracker tracker; // Create a model based tracker.
vpHomogeneousMatrix cMo; // Pose used to display the model.
// Acquire an image
vpImageIo::read(I, "cube.pgm");
#if defined(VISP_HAVE_X11)
display.init(I,100,100,"Mb Edge Tracker");
#endif
tracker.loadConfigFile("cube.xml"); // Load the configuration of the tracker
tracker.getCameraParameters(cam); // Get the camera parameters used by the tracker (from the configuration file).
// load the 3d model, to read .wrl model coin is required, if coin is not installed
// .cao file can be used.
tracker.loadModel("cube.cao");
while(true){
// acquire a new image
// Get the pose using any method
tracker.display(I, cMo, cam, vpColor::darkRed, 1, true); // Display the model at the computed pose.
}
return 0;
}

Add the lines to track from the polygon description. If the polygon has only two points, it defines a single line that is always visible. If it has three or more corners, it defines a face. In that case the visibility of the face is computed in order to track the corresponding lines only if the face is visible.

The id of the polygon is supposed to be set prior calling this function.

This method is called from the loadModel() one to add a face of the object to track.

Parameters

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
I_: The input image.
_pyramid: The pyramid of image to build from the input image.

◆ loadVRMLModel()

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.

Warning
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::fatalErrorif the file cannot be open.
Parameters
modelFile: The full name of the file containing the 3D model.

◆ setScales()

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

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.

scale: The vector describing the levels to use.
