void vpPylonGrabberGigE::setCameraIndex ( unsigned int  index )

virtual

If multiples cameras are connected on the bus, select the camera to dial with.

Parameters

index

: Current camera index, a value comprised between 0 (the first camera found on the bus) and the number of cameras found and returned by getNumCameras() minus 1.

If two cameras are connected on the bus, setting index to one allows to communicate with the second one. This identifier is not unique. That is why, it is also possible to select a camera by its serial number, which is unique using setCameraSerial().

Exceptions

vpException::badValue

: If the index is greater or equal to the number of cameras connected to the bus.

Returns

The measured exposure time in ms after applying the new setting.
