Detailed Description

Main methods for a model-based tracker.

This class provides the main methods for a model based tracker. This pure virtual class must be used in inheritance for a tracker that compute the interaction matrix and the residu vector using a defined information (edge, points of interest, patch, ...)

This class intends to define a common basis for object tracking. This is realised by implementing the main functions:

  • init() : Initialisation of the tracker (it includes re-initialisation). This method is called at the end of the initClick() method.
  • initFaceFromCorners() : Initialisation of the lines that has to be tracked.
  • track() : Tracking on the current image
  • testTracking() : Test the tracking. This method throws exception if the tracking failed.
  • display() : Display the model and eventually other information.

Compute projection error given an input image and camera pose, parameters. This projection error uses locations sampled exactly where the model is projected using the camera pose and intrinsic parameters. You may want to use

setProjectionErrorComputation
getProjectionError

to get a projection error computed at the ME locations after a call to track(). It works similarly to vpMbTracker::getProjectionError function:

Get the error angle between the gradient direction of the model features projected at the resulting pose and their normal. The error is expressed in degree between 0 and 90.

Parameters
I: Input grayscale image.
_cMo: Camera pose.
_cam: Camera parameters.

Reimplemented in vpMbGenericTracker.

◆ loadVRMLModel()

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

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

Warning
When this class is called, remember that you have to call Call SoDD::finish() before ending the program.
int main()
{
...
#if defined(VISP_HAVE_COIN3D) && (COIN_MAJOR_VERSION >= 2)
SoDB::finish();
#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::fatalErrorif the file cannot be open.
Parameters
modelFile: The full name of the file containing the 3D model.
