Member Function Documentation

void vpMbtDistanceCircle::buildFrom ( const vpPoint _p1,
const vpPoint _p2,
const vpPoint _p3,
const double  r 
)

Build a vpMbtDistanceCircle thanks to its center, 3 points (including the center) with coordinates expressed in the object frame and defining the plane that contain the circle and its radius.

Parameters
_p1: Center of the circle.
_p2,_p3: Two points on the plane containing the circle. With the center of the circle we have 3 points defining the plane that contains the circle.
r: Radius of the circle.

Display the circle. The 3D circle is projected into the image as an ellipse.

Parameters
I: The image.
cMo: Pose used to project the 3D model into the image.
camera: The camera parameters.
col: The desired color.
thickness: The thickness of the lines.
displayFullModel: When true, display the circle even if non visible. If false, display the circle only if visible.

Display the cylinder. The 3D cylinder is projected into the image.

Parameters
I: The image.
cMo: Pose used to project the 3D model into the image.
camera: The camera parameters.
col: The desired color.
thickness: The thickness of the lines.
displayFullModel: When true, display the circle even if non visible. If false, display the circle only if visible.

void vpMbtDistanceCircle::displayMovingEdges ( const vpImage< unsigned char > &  I)

Enable to display the points along the ellipse with a color corresponding to their state.

  • If green : The vpMeSite is a good point.
  • If blue : The point is removed because of the vpMeSite tracking phase (constrast problem).
  • If purple : The point is removed because of the vpMeSite tracking phase (threshold problem).
  • If blue : The point is removed because of the robust method in the virtual visual servoing.
Parameters
I: The image.

void vpMbtDistanceCircle::getCameraParameters ( vpCameraParameters camera)
inline

Get the camera paramters.

Parameters
camera: The vpCameraParameters used to store the camera parameters.

bool vpMbtDistanceCircle::initMovingEdge ( const vpImage< unsigned char > &  I,
const vpHomogeneousMatrix cMo

Initialize the moving edge thanks to a given pose of the camera. The 3D model is projected into the image to create moving edges along the circle.

Parameters
I: The image.
cMo: The pose of the camera used to initialize the moving edges.
Returns
false if an error occur, true otherwise.
