PURPOSE: A device and a method for measuring an angle using a complementary filter are provided to prevent a delay of a responding speed by using an n-th complementary filter in which an n-th low-pass filter, an n-th high-pass filter, and a least-squares method are applied. CONSTITUTION: A device for measuring an angle using a complementary filter(200) comprises a first sensor, a second sensor, a control unit, and a output unit. The first sensor senses the angular velocity with respect to a movement of a subject. The second sensor detects an angle with respect to the movement of the subject. The control unit calculates an angle value with respect to the movement of the subject based on the output value output from the first and second sensors. The output unit outputs the angle value with respect to the movement of the subject. The complementary filter comprises a calculation member, an n-th low-pass filter, an n-th high-pass filter, an integrating member, and an integral calculus member. |
