You are saying that the bottom picture from lidarview is a display of the .ply created from the example?

What does the disparity look like?

Hey Tetragramm, yes, the picture is a display from the points which cv.reprojectImageTo3D(disp, Q) returned. So the color ísn't visualized. The Disparity picture is added.

I don't actually do much with Stereo, but take a look at THIS tutorial. It seems to represent your issue.
