NumberOfDisparities

The number of disparities in pixels where correspondences in the stereo image pair are being searched, starting at MinDisparity. The resolution reductions by Scaling and Binning are automatically accounted for. The actual value used in the matching process is output in ScaledNumberOfDisparities.

Note

When using the PatchMatch Method this parameter only has an effect when EnforceDisparityRange is enabled.

Note

The value is clipped such that the ScaledNumberOfDisparities does not exceed 256 unless the PatchMatch Method is used.

Format

Number

An integer specifying the number of disparities in pixels where the images are being matched.

Note

The NumberOfDisparities parameter must be a multiple of 32.

Default

128

Example

In the illustration below the search range for a pixel in the left image is shown. The MinDisparity parameter describes the offset of the search range, whereas the NumberOfDisparities parameter indicates the length of the search range in pixels in the rectified images.
