Betterment of attitude estimation based on complementary filter applied in drumstick

For the problem of attitude estimation of drumstick in strenuous exercise, a detailed analysis of the attitude estimation process of complementary filter is done and the difficult issues during this process are proposed. The old attitude estimation based on complementary filter algorithm is improved. Experimental results show out that Betterment of attitude estimation based on complementary filter can solve high precision attitude of drumstick in strenuous exercise, and the virtual drums can be played successfully.
