How to solve TF_NAN_INPUT
Hi, I'm quite new to vslam and I was wondering if anyone who could help me with this problem. When I try to get live data using a bumblebee2 camera and rviz, the blue lines get all broken and scattered in weird places. like this: 
I suspect the following error message below(it was reported in my rviz window) will show what is responsible for this, but I cannot interpret where the error is. Thanks for the help.
[ERROR] [1306481857.228246721]: TF_NAN_INPUT: Ignoring transform for child_frame_id "/visual_odom" from authority "/bumblebee2/stereo_vslam_node" because of a nan value in the transform (nan nan nan) (-nan nan nan -nan)

It would help if you post exactly what you're running - any relevant launch files or commands. Are there any other errors or warnings in the console or the logs? Also the title doesn't seem to have anything to do with the question - consider renaming, "TF_NAN_INPUT in vslam" for example

I got this message from several nodes while calling the tf static_transform_publisher (with a all zero transform, needed for move_base) in a bash. Putting the same call as a node in the move_base launch file kept the error away, nevertheless I do not understand it.

I'd recommend to change the title to something like "How to solve TF_NAN_INPUT". I fail to see how your question is related to rosbag record.
