Member Function Documentation

◆ compute()

virtual void cv::StereoMatcher::compute ( InputArray  left,
InputArray  right,
OutputArray  disparity 
)
pure virtual
Python:
disparity=cv.StereoMatcher.compute(left, right[, disparity])

Computes disparity map for the specified stereo pair.

Parameters
leftLeft 8-bit single-channel image.
rightRight image of the same size and the same type as the left one.
disparityOutput disparity map. It has the same size as the input images. Some algorithms, like StereoBM or StereoSGBM compute 16-bit fixed-point disparity map (where each disparity value has 4 fractional bits), whereas other algorithms output 32-bit floating-point disparity map.

Implemented in cv::cuda::StereoSGM.
