Hi @ju-mingyue, in order to use that funktion RTAB-Map has to be built from source like this:
$ sudo apt remove ros-$ROS_DISTRO-rtabmap-ros
$ cd ~/catkin_ws/src
$ git clone -b $ROS_DISTRO-devel https://github.com/introlab/rtabmap_ros.git
$ cd ~/catkin_ws
$ catkin_make -DRTABMAP_SYNC_MULTI_RGBD=ON
@taletovic Thank you very much for your help. Now I have a new problem. My D435 camera will suddenly detect a non-existent obstacle and add it to the costmap, causing the robot to change its path.
Following parameters could be used to filter noise:
rtabmap --params | grep Grid/
Param: Grid/NoiseFilteringMinNeighbors = "5" [Noise filtering minimum neighbors.]
Param: Grid/NoiseFilteringRadius = "0.0" [Noise filtering radius (0=disabled). Done after segmentation.]
@matlabbe I'm very sorry, I gave up using rtabmap. I chose the simplest method to convert the depth information of the d435 camera into a laser signal. In the end, the above problem appeared. With regard to the current method, do you have a way to solve the noise problem?
If you generate a 2d scan, you could easily filter the scan data by comparing previous and next ranges to find ranges that are noise and set them to 0.
Please if you solved the issue please let me know,I don't know how to adjust the time stamp of the rtabmap inputs
Hello, I have a problem when using two D435 cameras in combination with the rtabmap program. My program configuration is as follows: `

Problems after running as follows:![深度截图_选择区域_20210704134449](https://user-images.githubusercontent.com/81499872/124417950-e3af2b80-dd8c-11eb-970b-0edb2ad8e570.png)
I have looked for a lot of solutions, but still can't solve it, whether it is downloading the source package or using apt-get to download.
I have tried this link,But to no avail https://github.com/IntelRealSense/realsense-ros/wiki/SLAM-with-D435i
