Problems solved by technology
[0003] When the carrying orientation of the portable device relative to the carrier is different, the orientations of the three single axes in the coordinate system applied by the IMU will be different, and because the placement direction of the portable device relative to the carrier cannot be identified based on the IMU data measured by the IMU, Therefore, the IMU data measured by the IMU will lead to the inability to accurately identify the movement of the carrier
For example, suppose the portable device is a watch. When the watch is worn on the right wrist of the human body and the right hand of the human body is raised, and when the watch is worn on the left wrist of the human body and the left hand of the human body is drooping, the IMU data measured by the IMU are The same, and the IMU data measured by the IMU cannot identify whether the carrier is the right wrist or the left wrist of the human body, so the IMU data measured by the IMU will not be able to accurately identify the motion posture of the carrier

A motion recognition method, a portable device, and a machine-readable storage medium, the method is applied to a portable device, the portable device is used to detect the motion posture of a carrier, the portable device includes an inertial measurement unit, and the inertial measurement The unit is used to acquire IMU data, and the method includes: detecting that the current orientation of the inertial measurement unit is different from a preset orientation; and processing the IMU data according to the preset orientation. By applying the embodiments of the present invention, it is possible to accurately identify the movement posture of the carrier.
Description
technical field [0001] The present invention relates to the technical field of motion recognition, in particular to a motion recognition method, a portable device, and a machine-readable storage medium. Background technique [0002] IMU (Inertial Measurement Unit, Inertial Measurement Unit) consists of three uniaxial acceleration sensors and three uniaxial angular velocity sensors (gyroscopes), which can measure IMU data, including the acceleration data and angular velocity of the carrier in three-dimensional space Based on the data, an IMU can be installed in portable devices, such as wearable portable devices and handheld portable devices, and the motion posture of the carrier can be calculated according to the IMU data measured by the IMU. [0003] When the carrying orientation of the portable device relative to the carrier is different, the orientations of the three single axes in the coordinate system applied by the IMU will be different, and because the placement direc...
