2013-04-18 17:26:44 -0500 | commented answer | RGBDSlam crashes after a few minutes of running After adding this line "cv::reduce(descriptors, sums_vec, 1 /sum over columns/, CV_REDUCE_SUM, CV_32FC1);" RGBDSlam hasn't been crashing. Thanks for yall's help. |
2013-04-12 07:16:44 -0500 | commented answer | RGBDSlam crashes after a few minutes of running Also, Felix, I tried to uncomment #ADD_DEFINITIONS(-DRGB_IS_4TH_DIM) and recompile but it gave me a warning that it was dangerous to do that so I didn't do it. |
2013-04-12 06:37:19 -0500 | commented answer | RGBDSlam crashes after a few minutes of running Felix, a few updates. I updated the code and recompiled and set the visualization_skip_step parameter to 3. I ran rgbdslam in headless mode and it crashed after running for a little over 4 mins. I posted the output in the original post. Thanks for your input. |

2013-04-03 10:58:50 -0500 | asked a question | RGBDSlam crashes after a few minutes of running Hi, I am running RGBDSlam along with slam_gmapping and hector_exploration_node. Basically, my robot uses hector_Exploration to navigate by using a 2D map created from slam_gmapping. While this is happening, I am running RGBDSlam to create a 3D map. The problem I am having is that when I run RGBDSlam for longer than 3 mins, the GUI disappears and it crashes. I have been getting exit codes 6 and 11. I switched to RGBDSlam headless mode and it seemed to map for 5 mins without crashing but when I tried to save the file, it said it saved but it never showed up in the directory I saved to and the computer crashed. So, I was wondering if anyone else has these issues and if there are any solutions. Any help will be appreciated, thank you! EDIT: This is the debug output when I ran RGBDSlam with the GUI and RGBDSlam crashed. (more) |

2013-03-25 13:26:20 -0500 | commented answer | help with hector_exploration and hector_mapping Okay, that makes sense. I ended up using gmapping instead and hector_exploration_node and it seems to be working now. The robot moves faster than I would like it to move but I think I need to mess with config files a bit more. Thanks for all your help! |

2013-03-24 17:31:54 -0500 | asked a question | help with hector_exploration and hector_mapping Hi, I am trying to run hector_exploration_node and hector_mapping. First, I launch the pointcloud_to_laserscan (I am using a kinect and getting laser scan data from pointcloud_to_laserscan), then I run the launch file for hector mapping, and then I run the launch file for hector_exploration_node. I also have segway drivers running in the background. After launching hector_ exploration_node, I get this warning: Waiting on transform from /base_link to /map to become available before running costmap, tf error: After messing with the launch file, I managed to get this warning: Waiting on transform from /base_link to /map to become available before running costmap, tf error: Could not find a connection between '/map' and '/base_link' because they are not part of the same tree.Tf has two or more unconnected trees. I edited the hector_ugv.launch file and added the following: "node pkg="tf" type="static_transform_publisher" name="base_link_map_broadcaster" args="0 0 0 0 0 0 base_link map 100" After this, I managed to get rid of the previous error and now it says "Initializing hectorExplorationPlanner" but does not do anything after that. I have read through the other similar questions but I do not understand the solutions posted. I am also wondering why I did not get a specific tf error in the first place and if the edit that I made to get rid of the tf error is even correct. Another thing, can I simply install and run hector_exploration_node as it is or do I need to change some configurations? If so, what configurations should I change? Any help would be sincerely appreciated, thank you! |

2013-02-24 11:53:41 -0500 | commented answer | RGBDSlam Point Cloud Scaling Felix, thanks for your help. I was able to figure it out and the map looks great now. One thing though, the file's path was src/graph_manager.cpp (lines 1361-1363). |
2013-02-23 06:47:29 -0500 | commented question | RGBDSlam Point Cloud Scaling I want to process the point cloud automatically, because I will be processing a lot of clouds. Does meshlab have a way to run a script or something to automatically resize a point cloud? |

2013-02-20 08:27:31 -0500 | asked a question | RGBDSlam Point Cloud Scaling Hi, I am trying to display the data collected by RGBDSlam as a .ply file on a separate program (web GUI by XB PointStream). The problem is that when this file is displayed on the GUI, it comes out very tiny and all the points look very close together. Is there a way to scale up the size of the point cloud data so that it displays correctly on XB PointStream? |
