I'm now using robot_localization package on Ubuntu 16.04. I want to fuse the data of pose (given by orb_slam2), imu and gps signal collected by DJI Matrice 100. But the result looks strange. I'm not sure whether my configuration is right or not.

Hi, I'm trying to use robot_localization to fuse two localization sources: amcl + feature-based localization.

How Also, I am fusing amcl with the algorithm because the robot possesses a Lidar sensor. The AMCL algorithm provides estimates for pose data to the ekf and it appears to be working adequately since the pose array converges; however, I have noticed that the ekf algorithm has been giving poor results with regard to localizing within the map.EKF Prerequisites sudo apt install ros-noetic-robot-localization -y Robot Localization. robot_localization is a ROS package, that contains a generalized form of EKF, that can be used for any number of sensors, and inputs.

On the other hand, I noticed that visual odometry is usually considered continuous, thus only one EKF is used. However, the map->odom transform is not static, so the second EKF looks like a good way to update it dynamically.…
