Member Function Documentation

copyMultiConfig()

ARMultiMarkerInfoT * ARTrackableMultiSquareAuto::copyMultiConfig

(

)

Make a copy of the multi config.

Caller must call arMultiFreeConfig() on the returned value when done.

Here is the call graph for this function:

initWithOriginMarkerUID()

bool ARTrackableMultiSquareAuto::initWithOriginMarkerUID	(	int	originMarkerUID,
		ARdouble	markerWidth
	)

updateWithDetectedMarkers()

bool ARTrackableMultiSquareAuto::updateWithDetectedMarkers	(	ARMarkerInfo *	markerInfo,
		int	markerNum,
		int	videoWidth,
		int	videoHeight,
		AR3DHandle *	ar3DHandle
	)

Updates the marker with new tracking info.

Then calls ARTrackable::update()

Parameters

markerInfo	Array containing detected marker information
markerNum	Number of items in the array
ar3DHandle	AR3DHandle used to extract marker pose.

Here is the call graph for this function:

updateWithDetectedMarkersStereo()

m_maxErr

ARdouble ARTrackableMultiSquareAuto::m_maxErr = 4.0f

The maximum allowable pose estimate error.

m_robustFlag

bool ARTrackableMultiSquareAuto::m_robustFlag = true

Flag specifying which pose estimation approach to use.
