hi
i implemented a one dimension(one vector) kalman filter. but the output has some problem. the biggest problem is that accelerometer has more power in out put and when i move device rapidly up and down the output become incorrect as you can see in pic in region A.
Region A is when i move device up and down without rotating as you can see in gyro output that device has just a little rotation.
can any one tell me where is the problem?
i use this guid to implement kalman filter
http://tom.pycke.be/mav/71/kalman-filtering-of-imu-data
here is three constant values:
E(alpha2) = 0.001
E(bias2) = 0.003
Sz = 0.3 (radians = 17.2 degrees)
how can i calc this values of my sensors? i think this const values causes my problem that i expalin it in first post.
