Your clouds look very good!

Regarding the video on the viso2_ros wiki page: The object is at a distance of about 1m and it has a very good texture. To get the reconstruction, we downsampled the point clouds using VoxelGridFilter and accumulated them in rviz using viso2_ros to generate odometry, setting the fixed frame in rviz to /odom and the decay time of the PointCloud2 display to 10 seconds. You can use fovis_ros for the visual odometry as well. There is no SLAM algorithm in the background so the reconstruction will suffer from drift after a couple of seconds. I don't remember what we got as epipolar error during our calibration. I think 0.25 is okay.

EDIT:

If you want to slow down processing (stereo_image_proc can get quite busy on calculating point clouds) you can throttle one input topic for stereo_image_proc.
