Member Data Documentation

◆ clip

int32_t osp::StereoMatchingSgmParams::clip

Clip value for cost (used to preserve overflow in cost function)

◆ ctWinSize

int32_t osp::StereoMatchingSgmParams::ctWinSize

Specifies the census transform window size

◆ filterTopArea

bool osp::StereoMatchingSgmParams::filterTopArea

Filter cost at top image area with low gradients

◆ hcWinSize

int32_t osp::StereoMatchingSgmParams::hcWinSize

Specifies the hamming cost window size

◆ maxDiff

int32_t osp::StereoMatchingSgmParams::maxDiff

Maximum allowed difference (in integer pixel units) in the left-right disparity check

◆ maxDisparity

int32_t osp::StereoMatchingSgmParams::maxDisparity

The maximum disparity value

◆ p1

int32_t osp::StereoMatchingSgmParams::p1

Smoothness penalty

◆ p2

int32_t osp::StereoMatchingSgmParams::p2

Discontiguous penalty

◆ pyramidalStereo

bool osp::StereoMatchingSgmParams::pyramidalStereo

Use pyramidal scheme: lower resolution imagery for nearby objects and the full resolution for far-away objects

◆ sad

int32_t osp::StereoMatchingSgmParams::sad

Specifies the average window size for sum of absolute differences (set to 1 for original SGM)

◆ scanlines

int osp::StereoMatchingSgmParams::scanlines

Scan line directions mask (Any bit-OR of ScanLineDirection values is suitable)

◆ uniqueness

int32_t osp::StereoMatchingSgmParams::uniqueness

Margin in percentage by which the best (minimum) computed cost function value should “win” the second best value to consider the found match correct
