bool osvr::vbtracker::DirectShowImageSource::ok ( ) const
inlineoverridevirtual
Returns
true if the camera/image source is OK

Implements osvr::vbtracker::ImageSource.

Definition at line 51 of file DirectShowImageSource.cpp.

bool osvr::vbtracker::DirectShowImageSource::grab ( )
overridevirtual

Trigger camera capture. May not necessarily include retrieval. Blocks until an image is available. or failure occurs.

Timestamp after this call returns.

Returns
false if the camera failed.

Implements osvr::vbtracker::ImageSource.

Definition at line 129 of file DirectShowImageSource.cpp.

void osvr::vbtracker::DirectShowImageSource::retrieveColor ( cv::Mat &  color,
osvr::util::time::TimeValue &  timestamp 
)
overridevirtual

For those devices that naturally read a non-corrupt color image, overriding just this method will let the default implementation of retrieve() do the RGB to Gray for you.

Implements osvr::vbtracker::ImageSource.
