    Man, this corner of RUclips right along with Ben Eater and 3brown1blue channels are among the best

      I agree, these three channel is the holy grail.

    Love the extra effort in addressing the drifting problem not only in a theoretical way, but showing this in an (un)practical scenario.

    Your channel is a pure bliss. Profound and still condensed knowledge.
    Are you planning on doing another video on FIR and IIR filtering including the FMAC peripheral of the stm32 MCs?

    • @PhilsLab
      @PhilsLab  3 года назад +1

      Thank you very much, Helge!
      I haven't planned any videos on the STM32's FMAC yet I'm afraid..

    I can't wait for the Kalman filter video, because I'm aware of it, and of sensor fusion in general, by quite a long time now.. however this may be the first time that I really understand it, because your explanations are really clear and to the essentials!!
    Thank you so much for your work!

  • @brus54per
    @brus54per 3 года назад +9

    Really nice presentation, thank you! Sensor fusion is a wonderful rabbit hole where one can spend all time until retirement if need be ;)
    It would be very nice if you would include quaternion-based solutions as well. With modern processors, that is a viable route that offers some very interesting possibilities. Good luck and happy fusioning!

  •  3 года назад +2

    Love the video and looking forward to the next part with sensor fusion, I have not yet managed to wrap my brain around Kalman filters.

    • @PhilsLab
      @PhilsLab  3 года назад

      Thank you! Hopefully the Kalman filter video can clear that up a bit :)

    The formula you used at 10:44 was seen in many articles, all of which uses “plus” quadcopter setup to mathematically model. But I always wonder if plus setup and X setup would be the same, or if I could use their result for an X quadcopter. If not, why use plus, while X is more practical.

    What I'd like to see more of is fusion with a structural model of the vehicle and MEMS combos at multiple points on the structure.

    This is a super welcome video, thanks for the effort! How about a 4th part too with quaternions? :)

    • @PhilsLab

      Thank you, Peet! Good idea, I may add a bonus quaternion-based EKF as a last video :)

    • @DrGreenGiant

      Came here to say the same thing about quaternions. This is what we did for an aerobatic UAV to get around the Euler issues at 90 degrees

    Thank you for this video, im greatly looking forward to this series. Have you looked into the Madjwick filter, it seems like it's less computationally expensive than the EKF
    Also do you plan on making a video on integrating the attitude estimates with GPS?

    • @PhilsLab
      @PhilsLab  3 года назад +3

      Thank you! I've played around with the Madgwick filter but wasn't happy with the performance and expandability in comparison with an EKF, although it is less computationally expensive.
      I'll probably add in IMU-based GPS-smoothing in a future video (not this series however, as this'll just cover the basics).

    Great content Phil - looking forward to the filters video.
    It would be useful if you could include commentary on additional sensors (e.g. magnetometer for yaw , thermal horizon sensing for pitch and roll).

    • @PhilsLab
      @PhilsLab  3 года назад +1

      Thank you very much, Mike! Yes, I'll touch on using a magnetometer for heading estimation when we come to the EKF!

  • @mostafakh5075
    @mostafakh5075 3 года назад

    that's what I'm working on it these days, great 👌. I'm implementing imu to achieve yaw. i set it on my desired point and set it to zero, then when i rotate that it gives me a good yaw at the first rotation but after that it start the random walk and drifting the system, i don't know how to solve it. in this case i dont use magnet

    I am really interested in learning all about IMU and all the implementation methods. I would like to really understand how everything works but even If I am an engineer I feel that I need to re-study everything again.
    Could you please recommend me some good technical books for learning about this?

    I'm getting a NaN when acc_x is greater than 9.81, because sin^-1 of something >1 is a Mathematical error, so I was wondering if it is due to my accel sensor reading or maybe the pass low filter or I have to declare a constraints? Btw, terrific tutorial, thank you a lot.
