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.

const

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

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

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.

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 [];
