Configuration file locate issue

Dear author,

First off, thank you so much for this open source sharing.

I have OS0-32 myself, and I wanted to get familiar with your example before proceeding to your example.

Here is my issue. Upon running the slam_launch.sh, I get the following error

slambox@slambox-NUC10i7FNH:~/ouster_slam_ws/src$ bash slam_launch.sh
... logging to /home/slambox/.ros/log/2f907054-b8e4-11eb-8788-f8ac65d8d6d2/roslaunch-slambox-NUC10i7FNH-24521.log

IOError: [Errno 2] No such file or directory: u'.../src/ouster_slam_ws/configuration_files/os1_16.lua/urdf/os_sensor.urdf'

As you can see from the last line, it seems to have trouble locating the .lua configuration file for the cartographer.

Here is my .sh file,

#!/bin/bash
source ../devel/setup.bash

BAGPATH='.../OS1-16_city1.bag' #own path
CONFIGPATH='.../sample_config_file_16.json' #own path

CARTOCONF='.../src/ouster_slam_ws/configuration_files/os1_16.lua' #own path

roslaunch ouster_slam os_slam.launch \
                             udp_hostname:=169.254.207.33 \
                             replay:=true \
                             bag_filename:=${BAGPATH}\
                             metadata:=${CONFIGPATH}\
                             carto_conf:=${CARTOCONF}

As you can see, I have correctly inputted by CARTOCONF location. But from the error message, it seems to be adding /urdf/os_sensor.urdf to whatever that is typed for CARTOCONF. Is this supposed to happen or is this a bug? What do you mean by CARTOCONF here? I thought you are referring to .lua file, not the urdf file.

Thank you for your generous help.

Best.

Map gets lost after some time on KITTI Run 007 at turns

Hi, I am trying to run cartographer using KITTI run 007. I preprocesed the dataset using a preprocessing step that turns the data into a range image of size [3,60,512]. The cartograher works well in straight lines but blunders at turns. I am clueless as to what coud be the issue here and tried different tricks with respect to the lua configuration, but didnt work. Could someone help here. I am posting the rosbag and the lua file here for refernece. KITTI bag used: kitti-run-007-bag Lua file used Lua This is the result using the bag with the given configuration. The map seems to get lost at the turns. Requesting your help here. Thanks. Prashant

Change .gitmodules

Please edit URL in .gitmodules file like this:
