Unable to run tune_blockmatcher and image_to_point

Question

I am able to capture images on webcams and calibrate them well using StereoVision library from erget.

But, while trying for execution of tune_blockmatcher and images_to_pointcloud, i found below errors as StereoBM and StereoSGBM classes are unable to import.

>import cv2
>from stereovision.blockmatchers import StereoBM, StereoSGBM
Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
 File "C:\Python27\lib\site-packages\stereovision\blockmatchers.py", line 111,

   class StereoBM(BlockMatcher):
 File "C:\Python27\lib\site-packages\stereovision\blockmatchers.py", line 117,
in StereoBM
   "stereo_bm_preset": cv2.STEREO_BM_NARROW_PRESET}
AttributeError: 'module' object has no attribute 'STEREO_BM_NARROW_PRESET'

OS i am running is Windows7, running OPENCV 3.4.0 and Python2.7, installed stereovision library with 'pip install StereoVision'

Any solution for this issue ?

Answer 1

You are facing this issue because the StereoVision framework provided by Daniel Lee does not work with OpenCV 3.

First of all, uninstall OpenCV 3 from your machine.

Then install OpenCV 2 and retry: your problem will be gone.

Hope this helps
