摘要
针对陀螺仪采集到的速度信号噪声大、平滑性不好以及采用一般工程数字滤波方法对数据处理求角加速度效果不佳的问题,提出了采用Savitzky-golay滤波方法对陀螺仪采集的速度信号进行数字滤波。所得滤波结果经微分处理,得到了角加速度波形,该波形较为平滑,保留了信号的主要特征,表明了此方法的有效性。
According to the problem of speed signal of gyroscope collected being large noise, poor smooth and the problem of the general project of digital filtering method to the date processing efficiency, this paper puts forward a new method of using Savitzky-golay digital filter to filter the speed signal of gyroscope collected. The filtering results by differential treatment obtain the angular acceleration waveforms. The waveform is smooth, retains the main characteristic signal and shows that the method is effective.
