StereoBM in OpenCV 3 (Python) missing module

you will have to use the 'create' function:

>>> help(cv2.StereoBM_create)
Help on built-in function StereoBM_create:

StereoBM_create(...)
    StereoBM_create([, numDisparities[, blockSize]]) -> retval

>>> help(cv2.StereoSGBM_create)
Help on built-in function StereoSGBM_create:

StereoSGBM_create(...)
    StereoSGBM_create(minDisparity, numDisparities, blockSize[, P1[, P2[, disp12MaxDiff[, preFilterCap[, uniquenessRatio[, speckleWindowSize[, speckleRange[, mode]]]]]]]]) -> retval

Thanks for the answer, it worked. Would you be so kind as to point me to some official documentation about this? The Python tutorials for OpenCV 3.0.0 still show the old createStereoBM()

yea, that needs to be changed ;)

at least samples/python2/stereo_match.py has it correct.

berak (Apr 14 '15)edit

actually no, it doesn't :/ AttributeError: 'module' object has no attribute 'StereoSGBM' . This is from a build based on mid-february commits because the python bindings were broken on opencv_contrib see this

techfort (Apr 14 '15)edit

what's exactly wrong now ?

berak (Apr 14 '15)edit

this line stereo = cv2.StereoSGBM(minDisparity = min_disp, calls StereoSGBM which python complains it's not an attribute of cv2. Maybe the method signature has changed?

techfort (Apr 15 '15)edit

dear, look at the answer again, please ;)

berak (Apr 15 '15)edit

Of course. Silly me, apologies! I will point out though that stereo_match.py still has the old signature :)

techfort (Apr 16 '15)edit

not true !

berak (Apr 16 '15)edit

Ok apologies again. My checkout of OpenCV 3 was about 4 months old.
