3D Map is not loaded

[Everest829]

hareware：jetson Xavier NX OS：Ubuntu 18.04，ROS Melodic Environment:CUDA 10.2.89 ; Opencv 4.4.0;ZED 2;ZED-SDK：ZED_SDK_Tegra_JP45_v3.4.0.run

I can't view the 3D Map generated when I launch the zed2.launch. The commands I executed are listed as follows： $roslaunch zed_wrapper zed2.launch camera_model:=zed2； $roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start" rgb_topic:=/zed2/zed_node/rgb/image_rect_color depth_topic:=/zed2/zed_node/depth/depth_registered camera_info_topic:=/zed2/zed_node/rgb/camera_info frame_id:=base_link approx_sync:=false visual_odometry:=false odom_topic:=/zed2/zed_node/odom. Finally,the result I got is shown as in the figure. Thanks in advance！

Unfortunately, this is an issue with the jetpack with incompatible VTK versus Qt libraries. See https://github.com/introlab/rtabmap/issues/427

I recommend to use RVIZ instead for visualization on the jetson. If you are on many computers and you want to use rtabmapviz, you could launch rtabmapviz on a laptop.

I have followed the method #427 ,but I got a new question when I input the shell command _cmake -DVTK_Group_Qt=ON -DVTK_QT_VERSION=4 -DBUILD_TESTING=OFF -DCMAKE_BUILD_TYPE=Release .. I have remove all Qt5 related vtk libraries installed in /usr/lib/aarch64-linux-gnu，and I install qt4

Which VTK version is used? PCL/Rtabmap won't build with VTK>=9. It looks like cmake is looking for QtWebkit, which is not installed.

I built vtk 6.3.0 from source，but I couldn‘t make it.The Qt version I've installed is Qt5.I followed the method you recommended，then I uninstalled Qt5 and I installed Qt4 successfully。In Part2，I can not execut the last step Cmake. Error occured， . So The place occured error is commented out Finally，I executed '_cmake -DVTK_Group_Qt=ON -DVTK_QT_VERSION=4 -DBUILD_TESTING=OFF -DCMAKE_BUILD_TYPE=Release ..',I got the result

Another solution is to use the docker image, see https://github.com/introlab/rtabmap/wiki/Installation#rtab-map-desktop-ubuntu-1804-2004 (updated from this issue https://github.com/introlab/rtabmap/issues/776), the 3D Map view is working properly.

Which computer are you using? the docker error contain cuda not found libraries, this is not rtabmap related.

Thanks,I will check it out.
