Methods

ComputePhaseMap(IInputArrayOfArrays, IOutputArray, IOutputArray, IInputArray)

Compute a wrapped phase map from sinusoidal patterns.

public void ComputePhaseMap(IInputArrayOfArrays patternImages, IOutputArray wrappedPhaseMap, IOutputArray shadowMask = null, IInputArray fundamental = null)

Parameters

patternImages IInputArrayOfArrays

Input data to compute the wrapped phase map.

wrappedPhaseMap IOutputArray

Wrapped phase map obtained through one of the three methods.

shadowMask IOutputArray

Mask used to discard shadow regions.

fundamental IInputArray

Fundamental matrix used to compute epipolar lines and ease the matching step.

DisposeObject()

protected override void DisposeObject()

UnwrapPhaseMap(IInputArray, IOutputArray, Size, IInputArray)

Unwrap the wrapped phase map to remove phase ambiguities.

public void UnwrapPhaseMap(IInputArray wrappedPhaseMap, IOutputArray unwrappedPhaseMap, Size camSize, IInputArray shadowMask = null)

Parameters

wrappedPhaseMap IInputArray

The wrapped phase map computed from the pattern.

unwrappedPhaseMap IOutputArray

The unwrapped phase map used to find correspondences between the two devices.

camSize Size

Resolution of the camera.

shadowMask IInputArray

Mask used to discard shadow regions.
