MPU-9250 and Arduino (9-Axis IMU) Introduction. It fuses angular velocities, accelerations, and (optionally) magnetic readings from a generic IMU device into an orientation quaternion, and publishes the fused data on the imu/data topic. I would like to know a way to get this values. The "typical" solution for us is to use odometry + IMU to get an ego-motion estimate and then use GPS to correct X,Y,Z and heading bias. Using its two “eyes” and through triangulation, the ZED provides a three-dimensional understanding of the scene it observes, allowing your application to become space and motion aware. I know the drift of IMU might not give a better position estimation than other sensors. Based on the work of [1]. There I will run an imu_madgick_filter node in order to get orientation and then fusing it with odometry from wheel encoder. Suggest Edits. It can support an unlimited number of inputs from multiple sensor types, and allows users to customize which sensor data fields are fused with the current state estimate.

(IMU) integrated with the Robot Operating System (ROS). In order to filter the IMU noise, gravity is observed over a certain amount of time. In robotic systems and frameworks such as ROS, the data used to measure these things is in the form of quaternion data. The stack contains: imu_filter_madgwick: a filter which fuses angular velocities, accelerations, and (optionally) magnetic readings from a generic IMU device into an orientation. ros::Time::now(). The method then publishes the data to RViz (ROS master). One way to get a better odometry from a robot is by fusing wheels odometry with IMU data. The sensor data that will be fused together comes from a robots inertial measurement unit (imu), rotary encoders (wheel odometry) and vision sensors (camera). Measurements from individual sensors in the IMU are fused, often using Kalman filters to avoid drift or bias, but are still not terribly stable. That is because retrieving the orientation requires to integrate angular velocities (raw measurements from a gyro) and possibly filter them to reduce biases! Such computation is performed by the madgwick IMU filter. To improve performance, modify properties of your imufilter object. I am using a ROS package called ethzasl-msf (I am using the multi sensor fusion because then I have to add. D research at the University of Bristol.
