I am using a videre stereo camera.When I try to view the stereo images using the stereo_image_proc it is giving the following warnings.

Left images received: 4381 (topic '/stereo/left/image_rect_color')

Right images received: 4427 (topic '/stereo/right/image_rect_color')

Disparity images received: 432 (topic '/stereo/disparity')

Synchronized triplets: 408

Possible issues:

* stereo_image_proc is not running.
  Does `rosnode info /stereo_view_1314808654600120880` show any connections?
* The cameras are not synchronized.
  Try restarting stereo_view with parameter _approximate_sync:=True
* The network is too slow. One or more images are dropped from each triplet.
  Try restarting stereo_view, increasing parameter 'queue_size' (currently 10)

I have read about the same kind of problem herelink text I have followed the suggestions given there by making the approximate_sync:=true and increasing the queue size to 10.But still the warnings persist.I wanted to know whether this will impact in disparity view as well as point cloud created.Thanking you

Are the images showing correctly in stereo_view, and do the pointclouds look reasonable? Possible solutions would be to increase the queue size even further.

@Helen The images are not showing correctly even in stereo_view..The images are contionously moving and there is noise in the images..What is the reason for this..
