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.

Definition at line 144 of file vpMbtDistanceCircle.h.

unsigned int vpMbtDistanceCircle::getIndex ( )

inline

Get the index of the circle.

Returns: Return the index of the line.

Definition at line 151 of file vpMbtDistanceCircle.h.

double vpMbtDistanceCircle::getMeanWeight ( ) const

inline

Get the mean weight of the circle. The mean weight is computed thanks to the weight of each moving edge. Those weights are computed by the robust estimation method used during the virtual visual servoing.

Returns: The mean weight of the circle.

Definition at line 160 of file vpMbtDistanceCircle.h.

std::string vpMbtDistanceCircle::getName ( ) const

inline

Get the name of the circle.

Returns: Return the name of the circle.

void vpMbtDistanceCircle::initInteractionMatrixError ( )

Get the polygon associated to the circle.

Returns: poly.

Initialize the size of the interaction matrix and the error vector.

		const vpHomogeneousMatrix &	cMo,
		const bool	doNotTrack,
		const vpImage< bool > *	mask = `NULL`
	)

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.
doNotTrack	: If true, ME are not tracked.
mask	Mask image or NULL if not wanted. Mask values that are set to true are considered in the tracking. To disable a pixel, set false.

Returns: false if an error occur, true otherwise.
