Gait tasks have become a topic of increasing inter-est in biological engineering research in recent years. One way to obtain the gait cycle time (GCT) is to analyze a subject's gait acceleration signal as recorded by an inertial measurement unit (IMU) [1]. An accurate peak detection of the IMU acceleration has thus become a requirement for GCT analysis. This study proposes a detection procedure for accurately detecting the peaks in a noisy IMU acceleration signal based on a frequency-domain analysis of the acceleration.
近年来，步态任务已成为生物工程研究中日益受到关注的课题。获取步态周期时间（GCT）的一种方法是分析惯性测量单元（IMU）记录的受试者步态加速度信号[1]。因此，准确地检测 IMU 加速度的峰值成为 GCT 分析的要求。本研究提出了一种基于加速度频域分析的检测程序，用于准确检测噪声 IMU 加速度信号中的峰值。
