Detailed Description

Implementation of a wire frame simulator. Compared to the vpSimulator class, it does not require third party libraries to be used.

The simulator uses several frames to display the scene in the image. There are:

  • The world frame : This is a fixed frame used to compute the position of the other frames against each other. By default this frame is positionned at the same location as the initial object frame position.
  • The object frame : It is the frame linked to the object.
  • The camera frame : It is the frame linked to the main camera.
  • The external camera frame : It is the frame which corresponds to one external point of view.

The most used homogeneous matrices which describes the displacement between two frames are :

  • fMo which is the displacement between the world frame and the object frame.
  • cMo which is the displacement between the main camera frame and the object frame.
  • cextMf which is the displacement between one external camera frame and the world frame.

The following picture summarize all the previous information.

vpWireFrameSimulator.jpeg

The simulator uses .bnd or .wrl files as 3D scene descriptors. Several scenes can be found in the data folder which is in the directory where you build ViSP.

You can move the main external view while clicking in the image. The left click enables to turn, the middle button enables to zoom and the left to translate along x and y.

The simulator is able to take into account to camera parameters. You can set the internal and external cameras parameters thanks to a vpCameraParameters.

The following example shows how it is easy to use.

#include <visp/vpImage.h>
#include <visp/vpWireFrameSimulator.h>
int main()
{
vpImage<vpRGBa> Iint(480,640,255);
vpImage<vpRGBa> Iext(480,640,255);
//Set the type of scene to use
//Set the initial pose of the camera
//Set the desired pose of the camera (for the internal view)
//Set the pose of the reference frame (for the external view)
//Set the camera parameters
vpCameraParameters camera(1000,1000,320,240);
//Get the internal view
sim.getInternalImage(Iint);
//Get the external view
sim.getExternalImage(Iext);
return 0;
}

void vpWireFrameSimulator::initScene ( const char *  obj)

Initialize the simulator. It enables to choose the type of scene which will be used to display the object at the current position. The object at the desired position is not displayed.

Here you can use the scene you want. You have to set the path to a .bnd or a .wrl file which is a 3D model file.

Parameters
obj: Path to the scene file you want to use.

void vpWireFrameSimulator::initScene ( const vpSceneObject obj,
const vpSceneDesiredObject desired_object,
const std::list< vpImageSimulator > &  imObj 
)

Initialize the simulator. It enables to choose the type of scene which will be used to display the object at the current position and at the desired position.

It exists several default scenes you can use. Use the vpSceneObject and the vpSceneDesiredObject attributes to use them in this method. The corresponding files are stored in the "data" folder which is in the ViSP build directory.

It is also possible to add a list of vpImageSimulator instances. They will be automatically projected into the image. The position of the four corners have to be given in the object frame.

Parameters
obj: Type of scene used to display the object at the current position.
desired_object: Type of scene used to display the object at the desired pose (in the internal view).
imObj: A list of vpImageSimulator instances.
