Abstract: A set of attitude detection system based on MEMS sensor is designed to obtain the angular velocity,acceleration and other information.The collected data is hardware filtered to achieve the measurement of the attitude angle of moving targets.Complementary filtering of data fusion effectively eliminates the noise interference and improves the detection accuracy of the system.The wireless module realizes the synchronous of lower computer and upper computer with real-time display of the motion attitude of the target.Experiments show that the system has high precision and good performance of real-time display.
