Problems solved by technology
This method has relatively high requirements for the user's gestures. If the user's gestures are different from the standard actions, it is easy to fail to recognize the user's gestures, so the recognition accuracy is not high.

A gesture recognition method applied in the technical field of wearable devices, including: S1, initializing the attitude quaternion of the inertial sensor, the three-axis acceleration vector of the inertial sensor in the geographic coordinate system, and the three-axis acceleration vector of the inertial sensor in the body coordinate system. Axis gyroscope vector and gesture feature code, S2, obtain the three-axis acceleration vector and three-axis gyroscope vector, S3, based on the three-axis acceleration vector and three-axis gyroscope vector, determine whether the state of the inertial sensor is a non-stationary state, S4, Calculate and record the motion vector angle based on the three-axis acceleration vector, S5, determine the gesture identification code based on the motion vector angle, S6, update the gesture feature code based on the gesture identification code, S7, search in the preset gesture feature code library Gesture signature to identify user gestures. The present disclosure also provides a gesture recognition device, device and storage medium. The present disclosure effectively solves the problem of low recognition accuracy caused by high requirements on gesture actions in the prior art.
Description
technical field [0001] The present disclosure relates to the technical field of wearable devices, and in particular to a gesture recognition method, device and storage medium. Background technique [0002] Smart wearable devices are currently one of the hot topics in the field of consumer electronics. Using inertial sensors on wearable devices, such as accelerometers, gyroscopes, etc., the wearer's gestures can be detected and recognized. Compared with the gesture recognition method based on vision, the gesture recognition method based on inertial sensor has the advantages of not being affected by ambient light, fast recognition speed, and low cost. [0003] At present, the gesture recognition method based on the inertial sensor will establish a gesture action library, which contains a large number of gesture action features, and gestures are recognized by comparing the action features sensed by the inertial sensor with the gesture action features in the gesture action libr...
