For **Jetpack 4** (Ubuntu 18.04 with ROS Melodic), see this [post](https://github.com/introlab/rtabmap/issues/427#issuecomment-608052821). + To use `rtabmap_ros` on Jetson, you can follow the instructions above if you don't care if OpenCV is built for Tegra. However, if you want `rtabmap` to use OpenCV 4 Tegra, we must re-build [vision_opencv](https://github.com/ros-perception/vision_opencv) stack from source too to avoid conflicts with [vision_opencv](https://github.com/ros-perception/vision_opencv) stack binaries from ros (which are linked on a not optimized version of OpenCV). Here are the steps: 1. Install [JetPack](https://developer.nvidia.com/embedded/jetpack) with OpenCV on the Jetson. 2. Do steps 1.2 and 1.3 from http://wiki.ros.org/kinetic/Installation/Ubuntu 3.
