Hi everybody, i'm working on Rviz, after opening it:

roscore
rosrun rviz rviz

and open a configuration:

rviz_config.rviz

that the instuction of SVO gives me

it give me an errore on the fixed frame:

No tf data.  Actual error: Fixed Frame [world] does not exist

and i cannot display nothing on my grid and cannot change my markers that doesn't work on image... i'm new on rviz, did someone know how solve the problem?? cause yesterday was working well.... for more precision, i'm working on the svo instruction, with the video from the bag.

thanks

Hi everybody,

i'm looking for a method that could help me visualize a pointcloud in .ply format, saved from LSD (pressing the "p" while it is mapping) in Rviz. did somebody could help me? thanks

Hi, i'm using octomap to obtain a 2dmap from a 3d pointcloud. i'm looking for a method for scale the pointcloud in meter, knowing the distance between two knowing points of the pointcloud. there is a way to modify the distances and so obtain a right scaled 2dmap?

Hi everybody. Installing the "scan_tools" on hydro 12.04, while give the catkin_make, it gives me:

gsl home: 
DBG GSL_CONFIG GSL_CONFIG-NOTFOUND
FATAL_ERROR,FindGSL.cmake: gsl-config not found. Please set it manually. GSL_CONFIG=GSL_CONFIG-NOTFOUND
CMake Error at sm/CMakeLists.txt:30 (MESSAGE):

do somebody knows how to solve?? thanks

i cannot understand what from-paths src and --ignore-src -- means can you explain well or link some pages? cause i really cannot understand what you'd write.

hi, after give from terminal the catkin_make command, it give an error that say:

CMake Error at /home/jacopo/catkin_ws/devel/share/pcl_ros/cmake/pcl_rosConfig.cmake:106 (message):
  Project 'pcl_ros' specifies '/usr/include/ni' as an include dir, which is
  not found.  It does neither exist as an absolute directory nor in
  '/home/jacopo/catkin_ws/src/perception_pcl-indigo-devel/pcl_ros//usr/include/ni'.

i've found in the web that the manual removing of the /usr/include/ni from the /opt/ros/hydro/share/pcl_ros/cmake/pcl_rosConfig.cmake can solve the problem. after removing it, you could see that the error is no more from that directory, but from the devel directory of catkin... how i can solve that problem??

using catkin, i have only the same directories etc that you could see here https://github.com/ros-perception/perception_pcl. i'm doing it in the wrong way?? after i use catkin_make and it run, but without the lib ply and i cannot use your apt-get

i don't have pcl-1.7 this is probably the cause of the missing libraries... but i cannot find it for hydro, all i can find on github for hydro is: https://github.com/ros-perception/perception_pcl and libraries aren't in there

i'm having some problems: for using functions that convert/visualize from a .ply file, i need the ply:io.h for the #include, but i don't have it in my pcl directory. i'm using ros hydro. somebody could helpe me?
