The invention relates to the technical field of action recognition, in particular to a pattern rope skipping action recognition system and method, and the system comprises a limb angle collection module, a stability recognition module, an action triggering and screening module, a rope body direction analysis module and a cross mapping judgment module. According to the method, by introducing three-dimensional coordinate extraction and included angle change trend analysis of limb key joints in the jumping period, the dynamic characteristics of limbs in the action process can be accurately reflected, and the action amplitude and stability change can be effectively expressed through an angle data sequence constructed by multi-dimensional indexes such as the maximum value, the minimum value and the average value of the included angle in the period; a stability identification mechanism is constructed to carry out local regression fitting and residual error statistics on a periodic angle trend, accurate labeling of a stable state of an action posture is realized, and then a key frame sequence with an actual jump intention and a continuous posture in the jump action is effectively identified through fusion screening of labeled frames and a jump-empty state.

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.
