Package topo :: Package misc :: Module robotics :: Class PTZ

Class PTZ

Pan/Tilt/Zoom control.

This event processor takes input events on its 'Saccade' input port in the form of (amplitude,direction) saccade commands (as produced by the topo.sheet.saccade.SaccadeController class) and appropriately servoes the attached PTZ object. There is not currently any dynamic zoom control, though the static zoom level can be set as a parameter.

start(self)
Called by the simulation when the EventProcessor is added to the simulation.

input_event(self, conn, data)
Called by the simulation when an EPConnectionEvent is delivered; the EventProcessor should process the data somehow.

Method Details

[hide private]

start(self)

source code

Called by the simulation when the EventProcessor is added to the simulation.

If an EventProcessor needs to have any code run when it is added to the simulation, the code can be put into this method in the subclass.

Overrides: base.simulation.EventProcessor.start: (inherited documentation)

input_event(self, conn, data)

source code

Called by the simulation when an EPConnectionEvent is delivered; the EventProcessor should process the data somehow.

Overrides: base.simulation.EventProcessor.input_event: (inherited documentation)
