I'm trying to follow http://www.ros.org/wiki/sba/Tutorials/PerformingSBAOnDataFromFile (Performing SBA on Data from File). It has been running on ROS Groovy Galapagos on Ubuntu 12.04.

In the last part, Visualization with Rviz of the http://www.ros.org/wiki/sba/Tutorials/PerformingSBAOnDataFromFile (Performing SBA on Data from File), Rviz shows strange visualization because landmark points(x,y,z) and camera pose(x,y,z) in the result file have different sign in x values each other. I generated the result file by using writeBundlerFile() after running sparse bundle adjustment with sample_bundler_file.out.

This is the some part of the result file.
