Description

set_origin_poseset_origin_poseSetOriginPoseSetOriginPoseSetOriginPose translates the origin of the 3D pose PoseInPoseInPoseInPoseInposeIn by the vector given by DXDXDXDXDX, DYDYDYDYDY, and DZDZDZDZDZ and returns the result in PoseNewOriginPoseNewOriginPoseNewOriginPoseNewOriginposeNewOrigin. Note that the translation is performed relative to the local coordinate system of the pose itself. For example, if PoseInPoseInPoseInPoseInposeIn describes the pose of an object in camera coordinates, PoseNewOriginPoseNewOriginPoseNewOriginPoseNewOriginposeNewOrigin is obtained by translating the object's coordinate system by DXDXDXDXDX along its own x-axis (and so on for the other axes) and not along the x-axis of the camera coordinate system. This corresponds to the following chain of transformations:

Thus, set_origin_poseset_origin_poseSetOriginPoseSetOriginPoseSetOriginPose is a shortcut for the following sequence of operator calls:

  pose_to_hom_mat3d (PoseIn, HomMat3DIn)
  hom_mat3d_translate_local (HomMat3DIn, DX, DY, DZ, HomMat3DNewOrigin)
  hom_mat3d_to_pose (HomMat3DNewOrigin, PoseNewOrigin)

A typical application of this operator when defining a world coordinate system by placing the standard calibration plate on the plane of measurements. In this case, the external camera parameters returned by camera_calibrationcamera_calibrationCameraCalibrationCameraCalibrationCameraCalibration correspond to a coordinate system that lies above the measurement plane, because the coordinate system of the calibration plate is located on its surface and the plate has a certain thickness. To correct the pose, call set_origin_poseset_origin_poseSetOriginPoseSetOriginPoseSetOriginPose with the translation vector (0,0,D), where D is the thickness of the calibration plate.
