Problems running ppl_detection in astar-ros-pkg

edit

Try changing line 468 of kinect_detect.cpp from: std::string model_string = "svm_models/" + model_name + ".model"; to: std::string model_string = "../svm_models/" + model_name + ".model";

This fixed the segfaulting for me.

If you believe the segmentation fault occurs at RViz, this thread might be of help.

Else if you experience seg-fault while trying to run kinect_detect, first of all the current implementation requires you run the command from the home directory of ppl_detection (by roscd ppl_detection or something. See around line#468 in kinect_detect.cpp where relative path of .model file is specified). Then try what @Liz Murphy suggests. If that still doesn't solve, modify the same part as:

std::string model_string = "./svm_models/" + model_name + ".model";

On one of my notebook (Ubuntu 11.04, Intel i7, ROS electric), I didn't have to do anything for kinect_detect, but on Turtlebot (eeepc), I had to do the above (maybe it's rooted in that the way fopen in C++ treats the current directory varies depending on the computer architecture? I haven't investigated further).

HTH.

If rviz gives you an error you can always try removing the temporary folder created by rviz. considering you are in home directory

rm -rf .rviz

Now restart the rviz.

If kinect_detect gives you a segmentation fault even after the above changes, then just re build it once again by assuming you are in ppl_detection package path

make

now do

rosrun ppl_detection kinect_detect

hope it helps :)

The launch file contains a strange reference to a "trainer" package.

If that is the problem, check whether you can find the launchfile (i.e. have a look into the package) or try to edit the launchfile and remove args="--display-config $(find trainer)/kinect_detect.vcg", you might then need to add the necessary displays manually.
