Sensor Fusion for Orientation Estimation

[@mehmetkilic9518]

Is it possible to integrate angular rates in order to get a set of euler angles. Shouldn't we consider a coordinate or reference frame conversation using like quaternion or dcm? After that we can use the corresponding results with the calculated ones come from accelerometer and magnetometer.

[@jenkner2352]

You must convert the angular rate that usually is projected into body frame in euler angular rate where each angle is in a different reference frame if you use intrinsic euler angle. After that convertion you can integrate the euler angular rate and obtain the euler angle. I hope is enought clear, you can find a lot on the web. :)

What is sample rate? Why did you set yours to 100 (11:05)? How do I determine a sample rate for my phone/calculation?

[@roboticseabass]

I believe 100 Hz was the maximum rate you can get from MATLAB Mobile. For a real sensor fusion application, you want to sample as quickly as possible to get good results, given the computational resources available.

Is it possible to track the imu position in the space for short periods of time like for less than five seconds using this app?

Do you have a demo for orientation estimation in smartphones? The one is the matlabcentral does not work well with several Android phones.

[@blackboardradio343]

when I run the code: orientation(i) = aFilter(a(i,:),w(i,:)); It says that the orientation expected to be 3 (in addition to System object), got 2. Could anyone have some solution?

@9:19 is that okay if i consider accelerometer data for prediction, and gyro data for correction

[@ThomasHaberkorn]

is there also a tutorial for position estimation based on the shown method?

[@ibrahimkayani240]

Did you find anything

[@fernando.liozzi.41878]

Hello, is it possible to do this in simulink? What would be the blocks? Thanks!, I need for code generation for a microcontroller.

[@roboticseabass]

Right now you can put these MATLAB objects into a MATLAB Function block in Simulink. This functionality does generate C code so it should work.

Good job, excelent lesson

[@hligfl]

Oh my god the guy saying yes all the time is so funny

[@ayuminor]

It's distracting me so hard haha

[@hoanchu7603]

thank for the lesson. It's really interessting. I'm trying to test it but when i try to log in my MATLAB Mobile , it always come the error " MATLAB Mobile is no longer supported with desktop MATLAB, use MATLAB Online instead." I try it on desktop version, online version and in mobile version too but it comes with the same error. How can i fix this error ? Thank u so much :)

I think we need extended simulink tutorial.

[@adamlevschuk571]

Could someone please explain lines 23-29 where they align the reference frames?

[@juralochie]

did you find an answer to this?

[@adamlevschuk571]

Jesse Gilham no I didnt

Sir can you help me...basic. learning of matlab please
