kylerlaird Posted April 17, 2017 at 08:42 PM Share Posted April 17, 2017 at 08:42 PM I use an IMU2 to maintain my tractor's heading. I would like to use it to estimate displacement over the 100ms period between my (10Hz) GPS updates. For now, I am only interested in displacement along X. In other words, if Y is aligned with the line I'm driving, how far away from the line have I moved in the last 0.1 second? I've tried accumulating acceleration[0] at various rates, resetting every 100ms, and moving the IMU back and forth by hand. It seems to be only vaguely related to displacement along X. Is this a reasonable thing to do with the IMU? Am I missing something obvious? Thank you. --kyler Quote Link to comment Share on other sites More sharing options...
DrWino Posted July 4, 2017 at 11:45 AM Share Posted July 4, 2017 at 11:45 AM IMHO - it is not possible to perform position odometry accurately using just a compass/IMU. You need a positional reference - such as GPS. I have been following your work and really RTK is the way to go with dual-RTK for heading. I have also build such a system and it works well. The real problem is continued operation when RTK is momentarily lost. This is where I am hoping the IMU may come in handy. Quote Link to comment Share on other sites More sharing options...
