Hi @narutojxl, the /map topic is the global map. You may check with rosrun rqt_graph rqt_graph. The laser mapping node is the final node to construct the optimized global map.
Yes, but in rviz, the map is like this:
I have no idea about this. BTW, I have modified
<param name="scan_line" value="16" />
of iscloam_mapping.launch
. There is a big delay, when pausing the played rosbag data.
@narutojxl for the small map it may happen. This is because the parameters I set is for large scale map. E.g., the resolution of the map. This may cause error mapping in your case. You may want to try another SLAM FLOAM under my project list https://github.com/wh200720041/floam.git for a quick test I provided the velodyne VLP-16 version in FLOAM which has been tested on my local VLP-16. For ISC-LOAM, I need to test on my local robot first, because I also need to change the parameters for intensity scan context. The VLP-16 version will be updated as soon as I finish the test.
@wh200720041, thanks very much, look forward to your ISC-LOAM test on vlp-16.
Hi @narutojxl, I have the same question as you, can you get the entire map?
Hi @wh200720041, thanks for your work! I have a vlp-16 bag data to run the demo. The topic
map
published byiscloam_laser_mapping_node
is not the whole map, right? How to see the whole map in rviz, thanks a lot!
