Abstract
A high-precision sensitive and portable “transmitter” of the hand gesture recognition system is designed in this paper. The MPU6050 sensor is used to collect the hand gesture data in real time. And the quaternion is obtained by the digital motion processing (DMP) unit of the sensor, and the Euler angle is obtained by the mathematical formulas operation. After that the complementary filtering correction algorithm is used to calculate the human hand gesture. Wireless modules are used to send data to the intelligent terminals and realize the function of wireless control of the intelligent terminals by hand gesture. Finally, the effectiveness and reliability of the scheme are verified by experiments. The experimental results show that compared with Euler angle method and direction cosine method, the attitude calculation method based on quaternion method and adding correction algorithm proposed by this scheme has the characteristics of less calculation, fast calculation speed and less drift error.
