mrpt::poses::FrameTransformerInterface< DIM > Class Template Referenceabstract

Detailed Description

template<int DIM>
class mrpt::poses::FrameTransformerInterface< DIM >

Virtual base class for interfaces to a ROS tf2-like service capable of "publishing" and "looking-up" relative poses between two "coordinate frames".

Use derived classes for:

Frame IDs are strings. MRPT modules use the standard ROS REP 105 document regarding common names for frames:

Template Parameters
DIMCan be 2 for SE(2), 2D transformations; or 3 for SE(3), 3D transformations.

◆ lookupTransform()

template<int DIM>
virtual FrameLookUpStatus mrpt::poses::FrameTransformerInterface< DIM >::lookupTransform ( const std::string target_frame,
const std::string source_frame,
light_type child_wrt_parent,
const mrpt::system::TTimeStamp  query_time = INVALID_TIMESTAMP,
const double  timeout_secs = .0 
)
pure virtual

Queries the current pose of target_frame wrt ("as seen from") source_frame.

It tries to return the pose at the given timepoint, unless it is INVALID_TIMESTAMP (default), which means returning the latest know transformation.

Parameters
timeout_secsTimeout

Implemented in mrpt::poses::FrameTransformer< DIM >, and mrpt::poses::FrameTransformer< 2 >.

◆ sendTransform()

template<int DIM>
virtual void mrpt::poses::FrameTransformerInterface< DIM >::sendTransform ( const std::string parent_frame,
const std::string child_frame,
const pose_t child_wrt_parent,
const mrpt::system::TTimeStamp timestamp = mrpt::system::now() 
)
pure virtual

Publish a time-stampped transform between two frames.
