ptam exist without error #103

Open rnunziata opened 6 years ago

rnunziata commented 6 years ago

ptam exist without error: There are no errors or warning in any of the logs files just 'process has died' . See full log files attached. System is ubuntu16, kinetic. How can I get more information?N

Note: this only happens when running from a launch file. If I run rosrun ptam ptam image:=/wide_stereo/left/image_rect and run the bag file it works ok.

OK...after recompiling now it just segfaults even on rosrun. Any idea on how to look at this kind of error .. my kingdom for a python implementation.

rosrun ptam ptam image:=/wide_stereo/left/image_rect
[ INFO] [1508205701.069258520]: starting ptam with node name /ptam

seems to a timing issue during initialization....if I hold roscore so the system has to wait then start it , it works...or it could be random too early to tell yet.
