    Discover common uses of Kalman filters by walking through some examples. A Kalman filter is an optimal estimation algorithm used to estimate states of a system from indirect and uncertain measurements.
    In the first example, you’re going to see how a Kalman filter can be used to estimate the state of a system (the internal temperature of a combustion chamber) from an indirect measurement (the external temperature of the combustion chamber).
    The second example demonstrates another common use of Kalman filters, in which you can optimally estimate the state of a system (e.g., the position of a car) by fusing measurements from multiple sources (e.g., an inertial measurement unit (IMU), an odometer, and a GPS receiver) in the presence of noisy measurements.

    While a speedometer claims to be measuring distance/time, it’s actually measuring revolutions/time of the tires, but displaying it as distance/time based on an assumption of tire size. As tires wear, the speedometer calibration changes.

    does it make sense to use a low pass filter on the sensor reading, before introducing it into the kalman filter?

    • @ArruVision
      @ArruVision 7 หลายเดือนก่อน

      I would like to know too, but based on my understanding so far, it seems the answer is no. A low pass filter will reduce noise based on the (crude) assumption that the variable observed by your sensor changes at a certain slow frequency, anything above is noise. Instead, you want the prediction model to provide this denoised, stable signal, and use the Kalman filter to combine it with the observed, noisy sensor data (leaving low pass filtering out). That’s my take anyway, anyone with deeper understanding please chime in :)

    I can honestly say this is a poor explanation of Kalman Filters. I first watched this video when I started learning about estimation 4 yrs ago, and have been studying and using them for work/research ever since. Kalman filters are used to estimate dynamical systems (ie a driving car). They have nothing to do with measuring variables indirectly; that’s pretty much what any estimation method would do. You also don’t talk at all about noise in this video. Kalman filters are great because they allow you to explicitly identify different noise sources in your sensor and your physics model.
