2013-11-19 18:09:01 -0500 | commented answer | how to use ethzasl_icp_mapping with velodyne? Hey, is odometry input (wheel, GPS, IMU) really necessary for node ethzasl_icp_mapping to work? I tried the node with velodyne 32E pcap file without any odometry input. But it couldn't output direction or move forward for more than 5m. After which it stopped at a point and kept adding points at the same place. |
2013-10-20 23:34:51 -0500 | asked a question | ethzasl_icp_mapping not moving forward while registering. Initially map moves forward a little bit but after that it just keep on adding points standing still at the same place. Is there problem with the launch file? I am using velodyne-32-E and configuration file from artor. this is the launch file I am using: |

2013-10-20 08:57:31 -0500 | asked a question | I am trying to use velodyne_height_map for velodyne HDL-32E. Actually I am new to ROS. I read velodyne_height_map link given on ros wiki carefully but may not have understood it completely so here is what is did.

I am using groovy and velodyne 32E for ethzasl_icp_mapper, but it keep on showing this error ERROR: cannot launch node of type [point_cloud_converter/point_cloud_converter]: point_cloud_converter artor file in launch folder i.e. artor_mapper.launch mentions this <remap from="cloud_in" to="/velodyne/assembled_cloud2"/> which really doesn't exist. |

2013-10-15 00:56:13 -0500 | commented answer | 3D SLAM & Velodyne HDL-32E I am trying to use velodyne_height_map for velodyne HDL-32E. Actually I am new to ROS and to the website also thatswhy posting my question here as the website says I nee dto increase my karma to post it on the website. I read this link(http://wiki.ros.org/velodyne_height_map) carefully but may not have understood it completely so here is what is did. 1. roslaunch velodyne_pointcloud 32e_points.launch calibration:=/home/user/32db.yaml (i.e. calling the velodyne point cloud which i think is subscriber and velodyne basic driver) 2. rosrun nodelet nodelet standalone velodyne_height_map/HeightMapNodelet (for using height based algo to get obstacles.) But, Its constantly showing this error ERROR: [ INFO] [1381872765.269655830]: height map parameters: 320x320, 0.5m cells, 0.25m threshold, not publishing full clouds |
