With the currently established workflow in minimally invasive robotic
surgery, autonomous tasks are merely replayed, since an adaption of the
mapping between the execution plan, the patient, and the manipulators is
difficult due to calibration issues. In the scope of this thesis we aim
to transit toward a more flexible approach by acquiring all relevant
information in situ at the time of execution. Perception of the
environment from the task-relevant perspective plays a major role, in
which visual information is the driving force. As a key concept, we
augment surgical instruments with miniaturized endoscopes. In addition,
a micro projection system enhances poorly textured surfaces with a
globally unambiguous binary pattern during depth perception. Visual
control laws are deduced from the knowledge acquired to assist surgeons
during task accomplishment. The approach is exemplarily explored based
on the reference task of tissue dissection.
