Detailed Description

Modelization of Irisa's gantry robot named Afma6.

In this modelization, 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().

void vpAfma6::getCameraParameters ( vpCameraParameters cam,

Warning
This method needs XML library to parse the file defined in vpAfma6::CONST_CAMERA_AFMA6_FILENAME and containing the camera parameters.
Third 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 is defined, this method gets the camera parameters from const_camera_Afma6.xml config file.
  • If this macro is not defined, this method sets 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.

◆ 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.
