Can opencv stitcher generate a full spherical panoramas like street view?

edit

Hi

I can stitch two or three horizontal pan angle images into one image using opencv. But I need to combine all 360X180 field of view into a single spherical panoramas file.

for example 6 horizontal images (at pan angles 0°, 60°, 120°, 180°, 240°, 300°) 2 images vertically up (at pan angle 0° and 90°) 2 images vertically down (at pan angle 0° and 90°)

Of course, we can use Hugin to finish this. But I am wondering ..

Can opencv stitcher generate a full spherical panorama??

Thank you
