I am trying to run RViz, then I receive the error,

Transform error: Could not find a connection between 'map' and 'arm1' because they are not part of the same tree.Tf has two or more unconnected trees.

I am publishing point clouds from LSD_SLAM to RViz to visualize a map.

I checked for, rosrun tf view_frames

and my tf looks like this,

C:\fakepath\frames.png

And I don't visualize the point cloud properly in RViz but just as a group of white clouds.

C:\fakepath\pointcloud.jpg

what could be the reason for this?

well, that certainly looks like you have two disconnected trees there: one with shadow as the root, and one with ardrone_base_link.

You should probably fix that.
