Detailed Description

Modelisation of Irisa's gantry robot named Afma6.

In this modelisation, different frames have to be considered.

${\cal F}_f$ : the reference frame, also called world frame
${\cal F}_e$ : the end-effector frame located at the intersection of the 3 rotations.
${\cal F}_c$ : the camera or tool frame, with $^f{\bf M}_c = ^f{\bf M}_e \; ^e{\bf M}_c$ where $^e{\bf M}_c$ is the result of a calibration stage. We can also consider a custom tool TOOL_CUSTOM and set this tool during robot initialisation or using set_eMc().

Examples:: testAfma6.cpp.

Get the current intrinsic camera parameters obtained by calibration.

Warning: This method needs XML library to parse the file defined in vpAfma6::CONST_CAMERA_AFMA6_FILENAME and containing the camera parameters. If XML is detected by ViSP, VISP_HAVE_XML2 macro is defined in include/visp3/core/vpConfig.h file.; Thid method needs also an access to the files containing the camera parameters in XML format. This access is available if VISP_HAVE_AFMA6_DATA macro is defined in include/visp3/core/vpConfig.h file.

If VISP_HAVE_AFMA6_DATA and VISP_HAVE_XML2 macros are defined, this method gets the camera parameters from const_camera_Afma6.xml config file.
If these two macros are not defined, this method set the camera parameters to default one.

Parameters

cam	: In output, camera parameters to fill.
image_width	: Image width used to compute camera calibration.
image_height	: Image height used to compute camera calibration.

◆ init() [6/6]

void vpAfma6::init	(	vpAfma6::vpAfma6ToolType	tool,
		vpCameraParameters::vpCameraParametersProjType	proj_model = `vpCameraParameters::perspectiveProjWithoutDistortion`
	)

Get the constant parameters related to the robot kinematics and to the end-effector to camera transformation (eMc) corresponding to the camera extrinsic parameters. These last parameters depend on the camera and projection model in use.

Warning: If the macro VISP_HAVE_AFMA6_DATA is defined in vpConfig.h this function reads the camera extrinsic parameters from the file corresponding to the specified camera type and projection type. Otherwise corresponding default parameters are loaded.

Parameters

tool	: Camera in use.
proj_model	: Projection model of the camera.

◆ parseConfigFile()

void vpAfma6::parseConfigFile ( const std::string & filename )

This function gets the robot constant parameters from a file.

Parameters

filename : File name containing the robot constant parameters, like max/min joint values, distance between 5 and 6 axis, coupling factor between axis 5 and 6, and the hand-to-eye homogeneous matrix.

void vpAfma6::set_eMc ( const vpHomogeneousMatrix & eMc )

virtual

Set the geometric transformation between the end-effector frame and the tool frame (commonly a camera).

Parameters
