Setting threshold according to characteristic parameters and identifying target muscle by machine learning algorithm
Judging whether the mean value and the variance exceed a preset threshold value or not to obtain a target-detected recognition result of the target muscle;
s4: parameter adjustment
Defining an impact force parameter as force, and representing the impact force of the treatment head;
defining a regulation parameter as gain, which represents the gain of regulating the impact force according to the muscle activity;
when the target muscle is successfully identified, the value of the target_detected variable is set to true, which will trigger subsequent operations to adjust the impact force parameter: adjusted_force=force×gain;
and adjusting the behavior of the treatment head according to the adjusted impact force parameters.
