Detailed Description

Process a stream of incoming timestamps, and generate a mean shift that synchronizes their time to this computer.

Use case: Timestamp series coming from another remote computer not synced to the clock of this computer should be run through this algorithm. This because CustusX stores its own timestamps during acquisition.

If the remote is in sync, either because it is localhost or otherwise synced using e.g. "sudo ntpdate -u time.euro.apple.com" on both machines or similar, this is not necessary.

Member Function Documentation

void cx::StreamedTimestampSynchronizer::addTimestamp

(

QDateTime

timestamp

)

Insert a new timestamp. Use it to update the shift estimate.

Definition at line 80 of file cxStreamedTimestampSynchronizer.cpp.

void cx::StreamedTimestampSynchronizer::addTimestamp

(

double

timestamp

)

Overloaded method, input is QDateTime::fromMSecsSinceEpoch(timestamp)

Definition at line 88 of file cxStreamedTimestampSynchronizer.cpp.

double cx::StreamedTimestampSynchronizer::getShift

(

)

const

Get the current shift, i.e. the correction to be applied to timestamps in order to synchronize them with this computer clock.

void cx::StreamedTimestampSynchronizer::syncToCurrentTime

(

ImagePtr

imgMsg

)

Utility for updating the shift based on the incoming image timestamp, and also synchronizing the image timestamp (i.e. shifting it).
