This paper presents … WebDec 1, 2024 · On the other hand, Madgwick filter assumes that the accelerometer measures gravity. This means that it is affected by horizontal accelerations. Filter parameters (the two it has) need to be adjusted for your specific case, achieving a tradeoff between gyro bias correction and sensitivity to horizontal accelerations.

WebDec 6, 2024 · They are actually the same orientation. The EKF requires a set of noise variances, which define the certainty of each sensor. By default, they are defined as 0.3^2 for the gyroscopes, 0.5^2 for the accelerometers, and 0.8^2 for the magnetometer. The smaller they are, the more you "trust" the sensor. Try redefining them when you create the class. http://wiki.ros.org/imu_complementary_filter
