Class Description

class compute_homography_process : public sprokit::process

Wrapper process around compute_ref_homography algorithm/.

\process This process instantiates a concrete implementation of the compute_ref_homography algorithm.

\iports

\iport{timestamp} time stamp for incoming images.

\iport{feature_track_set} track set to be used for calculating homography.

\oports

\oport{homography_src_to_ref} Resulting homography.

\configs

\config{homography_generator} Algorithm name for homography generator to use.

Other config parameters depend on the actual algorithm selected.
