Detailed Description

CaptureFactory for creating Capture classes.

CaptureFactory is a singleton that creates Capture classes used to perform camera acquisition. Different backends are implemented as dynamicly loaded plugins so that platform dependancies can be handled at runtime and not compile time.

Member Function Documentation

Capture * alvar::CaptureFactory::createCapture ( const CaptureDevice captureDevice )

Create Capture class. Transfers onwership to the caller.

If the needed backend plugin is not loaded, an attempt is made to load it and an instance of it is kept such that it is available for subsequent calls.

Parameters:

captureDevice CaptureDevice object specifying the plugin to use.

Returns:: A new Capture class for which the caller takes ownership.

Examples:: SampleCamCalib.cpp, SampleCvTestbed.cpp, SampleIntegralImage.cpp, SampleLabeling.cpp, SampleMarkerDetector.cpp, SampleMarkerHide.cpp, SampleMarkerlessDetector.cpp, SampleMultiMarker.cpp, SampleMultiMarkerBundle.cpp, SamplePointcloud.cpp, and SampleTrack.cpp.

CaptureFactory::CaptureDeviceVector alvar::CaptureFactory::enumerateDevices ( const std::string & captureType = "" )

Enumerate capture devices currently available.

This method should be used carfully since it will load all the known plugins and call their respective enumeration methods. The vector of CaptureDevice objects returned should be cached.

Parameters:

captureType Force the enumeration of only one type of plugin.
