2022-12-22 18:39:25 -0500 | marked best answer | [SOLVED] rviz not showing 16 bits-per-pixel, single channel depth images Hi, I am playing a bag of 16 bits-per-pixel depth and 8 bit rgb images. While playing the bag, I can extract both the rgb and the depth images into files (verifying that the data is ok) (I used the thread here to create and extract the depth images) The way the depth image is stored in the bag is by using a python script that uses the PIL package to read a pgm image from file into a PIL object, serialize the object data into byte array (using io.BytesIO()), and save the byte array in PPM format. In rviz I can view the rgb image, but I cannot view the depth image. rviz issues an error message: The transport Hint in rviz is set to "raw" and I cannot change it. Thanks, Avner |

2021-05-02 14:04:10 -0500 | marked best answer | Running rtabmap on bag of rgb and depth images Hi, I want to run ros rtabmap on a bag of rgb and depth images, with the following topics: I am using the well known canned bag rgbd_dataset_freiburg1_xyz as a reference example. This bag has the following topics: In my bag I don't have /imu, /tf topics. To get the program to flow, I added the following transforms. I added the transform with 0 values for x,y,z,rot,pitch,yaw (i.e. no effect), except for the yaw argument to align the orientation of 3d points with the image If I just play my bag, I can see in rviz the images (rgb, depth) and the 3d points (via /voxel_cloud), but in local frame coordinates. With these tf nodes the rtabmap runs, but the /rtabmap/mapData shows incorrect - the 3d points are just laid on top of each other without a proper 3d model. I created a bag rgbd_dataset_freiburg1_xyz_no_tf.bag without the topics: /cortex_marker_array /imu /tf, (and replaced with static transforms) With this setting, rtabmap creates the mapData incorrectly as well. So it looks like the launch file that I am using from here requires the topics that were filtered above. My questions:
Thanks, Avner |

2019-08-16 17:17:48 -0500 | marked best answer | [SOLVED] RTABMAP does not generate accumulated 3d points in rgbd mode Hi, I am running RTABMAP against a stereo camera that provides left and right and depth images. When I run RTABMAP in stereo_mode (based on left and right image pairs) RTABMAP is working OK (e.g. I can see the 3d point cloud being build in Rviz via the topic /rtabmap/mapData) Now I want to test RTABMAP in rgbd mode (based on right and depth image pairs). In this mode the rgbd_odometry runs OK, and produces odometry results (snippet1). I also echo the /rtabmap/odom topic and I can see published data. But nothing is published for topic /rtabmap/mapData. RTABMAP does publish data for topic /rtabmap/odom_local_map (see snippet2) To debug the problem, I list odom_local_map in Rviz and set the field "Fixed Frame" to "odom", but nothing is displayed in the 3d pane. How can I debug the problem, to see the accumulated 3d point cloud in Rviz? Or, how can I debug the problem, to see intermediate results such as odom_local_map in Rviz? Thanks, Avner EDIT: The RTABMAP launch files are listed in snippet3, snippet4 The ros related processes are in snippet5 snippet1 - rgb_odometry runs ok snippet2 - I can echo topic from /rtabmap/odom_local_map snapshot3 - RTABMAP launch file snippet4 - RTABMAP base launch file (more) |

When I run RTABMAP in stereo_mode (based on left and right image pairs) RTABMAP is working OK. (e.g. I can see the 3d point cloud being accumulated in Rviz) Next, I want to test RTABMAP in rgbd mode (based on right and depth image pairs). In this mode I'm getting error messages from RTABMAP (snippet1) I echo the /rtabmap/odom topic and indeed nothing is advertised. To debug the problem, I kill the rgbd_odometry process that is triggered from the launch file, and run the same command from the command line. This time rgbd_odometry runs OK, and I can echo the topic (snippet3) Why rgbd_odometry doesn't publish anything when it runs from the launch file, but publishes data when it runs separately? The launch files that are related to RTABMAP is in snippet4 Thanks, Avner snippet1 - getting error messages from RTABMAP snippet2 - run rgb_odometry directly from the command line snippet3 - echo the topic /odom (more) |
