What is complementary filter?
The complementary filter is a computationally inexpensive sensor fusion technique that consists of a low-pass and a high-pass filter. In this application of inertial-sensor-based attitude estimation, the gyroscope's dynamic motion characteristics are complementary to that of the accelerometer and magnetometer.
Is Kalman filter a complementary filter?
So basically the Kalman filter contains the complementary filter, and will behave as such with the most basic system possible that basically provides no additional information.
Why do we need complementary filters?
A complementary filter is a quick and effective method for blending measurements from an accelerometer and a gyroscope to generate an estimate for orientation.
