Detailed Description

Finds planes in Array3D<float>'s regions with high values. All positions in the array above a threshold (defined by cliprate) are used to find the planes.

The planes are defined with three parameters: dip (0-90), azi(0-360) and the normal's distance to origo. Depending on your application, you might need different resolution, which is set with setParamSpaceSize.

Usage: 1) Create 2) Set setParamSpaceSize, cliprate and data 3) Get the tasks and run them 4) call sortParamSpace 5) get your planes and their scores.

getPlane()

Plane3 PlaneFrom3DSpaceHoughTransform::getPlane

(

int

plane

)

const

Returns the plane plane from houghpositions converted to the ( x,y,z ) space.

incParamPos()

void PlaneFrom3DSpaceHoughTransform::incParamPos ( int  normal, double  dist  )

protected

setClipRate()

void PlaneFrom3DSpaceHoughTransform::setClipRate

(

float

)

Between 0-1. For instance, cliprate 0.6 will set Data with the 60% highest values of indata. Default is 0.7

setData()

void PlaneFrom3DSpaceHoughTransform::setData

(

const Array3D< float > *

)

setResolution()

void PlaneFrom3DSpaceHoughTransform::setResolution	(	double	dangle,
		int	distsize
	)

Parameters

dangle	is the angle between the planes that are tested.
distsize	is the number of bins in the distance domain.

sortParamSpace()

TopList<unsigned int, unsigned int>* PlaneFrom3DSpaceHoughTransform::sortParamSpace

(

int

)

const

Sorts the paramspace and returns an array with the indexes of the planes, from less likely planes to likely planes. The best plane is thus the res[getParamSpaceSize()-1] value. Result is managed by caller and should be deleted with [];
