C# Class Emgu.CV.StereoSGBM

This is a variation of "Stereo Processing by Semiglobal Matching and Mutual Information" by Heiko Hirschmuller. We match blocks rather than individual pixels, thus the algorithm is called SGBM (Semi-global block matching)

Inheritance: Emgu.Util.UnmanagedObject

Public Methods

Method	Description
FindStereoCorrespondence ( Byte>.Image left, Byte>.Image right, Int16>.Image disparity ) : void	Computes disparity map for the input rectified stereo pair. Invalid pixels (for which disparity can not be computed) are set to (state->minDisparity-1)*16
StereoSGBM ( int minDisparity, int numDisparities, int SADWindowSize, int P1, int P2, int disp12MaxDiff, int preFilterCap, int uniquenessRatio, int speckleWindowSize, int speckleRange, bool fullDP ) : System	Create a stereo disparity solver using StereoSGBM algorithm (combination of H. Hirschmuller + K. Konolige approaches)

Protected Methods

Method	Description
DisposeObject ( ) : void	Release the unmanged memory associated with this stereo solver

Method Details

DisposeObject() protected method

Release the unmanged memory associated with this stereo solver

protected DisposeObject ( ) : void
return	void

FindStereoCorrespondence() public method

Computes disparity map for the input rectified stereo pair.

Invalid pixels (for which disparity can not be computed) are set to (state->minDisparity-1)*16

public FindStereoCorrespondence ( Byte>.Image left, Byte>.Image right, Int16>.Image disparity ) : void
left	Byte>.Image	The left single-channel, 8-bit image
right	Byte>.Image	The right image of the same size and the same type
disparity	Int16>.Image	The output single-channel 16-bit signed disparity map of the same size as input images. Its elements will be the computed disparities, multiplied by 16 and rounded to integer's
return	void

StereoSGBM() public method

Create a stereo disparity solver using StereoSGBM algorithm (combination of H. Hirschmuller + K. Konolige approaches)

public StereoSGBM ( int minDisparity, int numDisparities, int SADWindowSize, int P1, int P2, int disp12MaxDiff, int preFilterCap, int uniquenessRatio, int speckleWindowSize, int speckleRange, bool fullDP ) : System
