Hi @Varun1407 thanks fo getting in touch! Did you follow the instructions of the readme file for compiling segmatch and laser_mapper?
Hi @rdube. thanks for the response. Yes I followed all the instruction as per the read me file. Now I am getting an error as below.
[FATAL] [1505220674.695524262]: Error opening file: /home/eberhardt/segmatchcatkin_ws/src/segmatch/laser_mapper/demonstration_files/kitti/2011_09_30_drive_18.bag [player-4] process has died [pid 3137, exit code 1, cmd /opt/ros/indigo/lib/rosbag/play -r 1 -s 0 --clock --pause /home/eberhardt/segmatchcatkin_ws/src/segmatch/laser_mapper/demonstration_files/kitti/2011_09_30_drive_18.bag name:=player log:=/home/eberhardt/.ros/log/0c484310-97b9-11e7-8644-3ca9f455f8e8/player-4.log]. log file: /home/eberhardt/.ros/log/0c484310-97b9-11e7-8644-3ca9f455f8e8/player-4*.log
I have converted the kitti dataset using the kitti to rosbag repository.
also in rviz I am getting the global status warning for fixed frame as below:
No tf data. Actual error: Fixed Frame [map] does not exist
You can get a bag file here: http://robotics.ethz.ch/segmatch/ and make sure that it is in the correct location.
I used the file you suggested but still I am getting the same error. I have placed it in the location as specified in the wiki for demonstrations of segmatch.
Most likely the file was not found. Can you recheck the path? eg. is the segmatchcatkin_ws folder correct?
Simply go to the folder where 2011_09_30_drive_18.bag
is located and do pwd to get the correct path.
I rectified the previous error. but now i am facing a new one. [laser_mapper-2] process has died [pid 30749, exit code -11, cmd /home/eberhardt/segmatchcatkin_ws/devel_isolated/laser_mapper/lib/laser_mapper/laser_mapper_node __name:=laser_mapper __log:=/home/eberhardt/.ros/log/40989b54-a85f-11e7-989b-3ca9f455f8e8/laser_mapper-2.log]. log file: /home/eberhardt/.ros/log/40989b54-a85f-11e7-989b-3ca9f455f8e8/laser_mapper-2*.log Kindly help to resolve this.
thanks.
@Varun1407 I believe that the issue is not related to the launch file anymore (or of not having the bag file at the correct location). Please consider closing and re-opening new issues when a given problem is fixed.
For this new issue you could use GBD to get more information. See #47
@Varun1407 did that help?
@Varun1407 given the delay I will assume that this has been solved on your side by now.
Hi all,
i am trying to execute the Kitti demo file as mentioned in the wiki page, but I am getting the following error.
--roslaunch laser_mapper kitti_loop_closure.launch error -- [kitti_loop_closure.launch] is neither a launch file in package [laser_mapper] nor is [laser_mapper] a launch file name The traceback for the exception was written to the log file
I have the launch files and bash setup accordingly, yet I am not able to execute. Kindly help.
Thanks in advance.
