Gazebo sensor plugins for barometric pressure Sensor with geometry_msgs/PointStamped?
I`m doing some underwater UUV Gazebo simulation and would like to use the hector_pose_estimationhector_pose_estimation package to fuse IMU and Fluid pressure sensors input for pose estimation. But when running the node I got ERROR
Client [/hector_pose_estimation] wants topic /rexrov2/pressure to have datatype/md5sum [geometry_msgs/PointStamped/c63aecb41bfdfd6b7e1fac37c7cbe7bf], but our version has [sensor_msgs/FluidPressure/804dc5cea1c5306d6a2eb80b9833befe]. Dropping connection.
So my Pressure Sensor has sensor_msgs/FluidPressure but the package wants pressure_height (geometry_msgs/PointStamped) as input. Any help where can find urdf xacro and gazebo ros plugins for barometric pressure with geometry_msgs/PointStamped?
Thanks
FluidPressure is water pressure, and the pressure_height is altitude derived from air pressure? You could interject a ros node to convert water pressure to depth below water, then pass that as a negative altitude in PointStamped form to hector, and see if that works. Maybe there are other underwater hector projects too look into?
Im not sure the pressure_height is altitude derived from air pressure . I know that hector_pose_estimation package need
pressure_height (geometry_msgs/PointStamped), Altitude from barometric pressureas input topic. . How to convert water pressure to depth below water?You might be better off asking in forum/stack devoted to ocean engineering or marine robotics (though possibly there is an off-the-shelf ros package that does the calculation).
Something like this doesn't look that difficult to duplicate in python/C++: https://bluerobotics.com/learn/pressu...
