The present invention discloses a method for identifying fancy rope skipping. The rope skipping device includes a 3-axis acceleration sensor, a 3-axis gyroscope, and a classifier. The 3-axis acceleration sensor is used to collect acceleration data of the 3 axes, and the 3-axis gyroscope is used to collect angular velocity data of the 3 axes. The acceleration and angular velocity data of the rope skipping are collected at the same sampling rate. The acquired angular velocity and acceleration data are fused into a quaternion. Each axis of the quaternion is subjected to a simplified bandpass filtering process. A feature window T1 within a preset time period is determined and searched. Feature data within the feature window T1 is extracted. The data in the feature window is input into a classifier, and the classifier identifies and determines whether it is a crossover action and performs a validity judgment. The present invention utilizes the quaternion data formed by the fusion of acceleration and angular velocity data to identify crossover actions in fancy rope skipping. This method does not require excessive resource consumption and can complete offline recognition at the rope skipping end.
