2016-05-03 04:01:39 -0500 | commented answer | Octree to Quadtree from Octomap hi, i came across the same problem, but after i modify the octomap_server_multilayer.cpp(/opt/ros/groovy/stacks/octomap_mapping), how do i rebuild the file to make the system know that the file has been changed? I tried rosmake, but i didn't work? Any suggestion? Thank you |

2016-01-22 04:25:21 -0500 | asked a question | error on pcl_viewer Hi everyone, I use rgbdslam v2 to build 3D map and I save the map to file .pcd format. When I use command pcl_viewer to read the file .pcd format, it says, The viewer window provides interactive commands; for help, press 'h' or 'H' from within the window. Loading quicksave.pcd [pcl::PCDReader::readHeader] No points to read.
I hope someone can help me solve it. Any suggestion is welcome.
Thanks in advance.

2016-01-22 03:21:51 -0500 | asked a question | error compiling g2o about g2o_viewer Hi everyone, Recently, I have been studying g2o link:[https://github.com/RainerKuemmerle/g2o] , an open-source C++ framework for optimizing graph-based nonlinear error functions, I followed the README in the file g2o. When i cmake the file, it all went well, but when i make it, it failed, which is run on ubuntu 14.04 indigo. Obviouly, making g2o_viewer went wrong.

2015-07-24 01:32:01 -0500 | asked a question | problems with OctoMap on ubuntu 12.04(groovy) Hi,guys I create 3D map using OctoMap , but I only can get the last frame not like the link http://ais.informatik.uni-freiburg.de... with kinect and hokuyo, which has annoyed me for a few weeks. The octomap_mapping.launch is as following: <launch>
<node pkg="octomap_server" type="octomap_server_node" name="octomap_server">
<param name="resolution" value="0.05">
<!-- fixed map frame (set to 'map' if SLAM or localization running!) -->
<param name="frame_id" type="string" value="odom_combined" />
<!-- maximum range to integrate (speedup!) -->
<param name="sensor_model/max_range" value="5.0" />
<!-- data source to integrate (PointCloud2) -->
<remap from="cloud_in" to="/narrow_stereo/points_filtered2" />
</node>
</launch>
When I use rxgraph , the type of topic /narrow_stereo/points_filtered2 is unknown and rostopic echo /narrow_stereo/points_filtered2 has no data output.
the topic of pointcloud2 is octomap_point_cloud_center and the topic of markerarray is occupied_cells_vis_array. I don't konw what is wrong. Hope someone can help me solve the problem.
Thanks in advance. cheers, jwlifly |
2015-07-22 02:56:05 -0500 | asked a question | 3D mapping using octomap + Kinect hi , everyone
i'm new to ros and i try to create a 3d map. Now I have a question about 3D mapping using OctoMap , which has annoyed me for a few weeks. Each time, I build a map with Microsoft XBOX 360 ,I always have the last scene not the global scene like the link http://ais.informatik.uni-freiburg.de... When I run the .launch file , I debug the programs using rostopic list , then use rostopic ehco /octomap_full etc , but no data outputs. Also what more frustrates me is that topic /narrow_stereo/points_filtered2 remapped from cloud_in does not output data , which I think cloud_in is not output anything data or even octomap_server doesn't work at all . In rviz, when I choose the topic /octomap_point_cloud_centers of PointCloud2, there is no image , but /camera/depth/points or /camera/depth_registered/points does. Maybe the tf transform is not right,either. I really don't know how to solve the problem. I hope someone can help me solve the problem. Any suggestion is appreciated. Thanks in advance. The detail of list and launch file is following. hustrobot@hustrobot-desktop:~$ roswtf
