The second change action is the operator's hand unfolding action lasting 2s or more. The reason for selecting the above actions as the first and last actions is: in actual operation, the operator will grasp a handful of tea leaves and place them in the palm of his hand when kneading. At this time, the other hand will close with the hand with the tea leaves to prepare for the kneading operation. Capturing at this time can ensure a more accurate start time. The unfolding action of the hand unfolding for 2s or more is selected because when the kneading is finished, the operator's hands will unfold and will not close again. At the same time, in order to avoid erroneous opening caused by operating errors in the middle, an unfolding time of more than 2s is determined. It should be noted that n in this implementation represents the last change in hand movement.

[0036]

[0037] in, The temperature of the last tea leaves Initial tea temperature The difference between is the standard temperature value.

[0038] when When the drying temperature is qualified; when or When the drying temperature is not up to standard, the drying process will continue, and the above steps will be repeated until the temperature of the tea leaves reaches the appropriate value after drying.

[0039] After completing the above steps, when the time and temperature results are qualified, the motion capture device, temperature collector and timer all stop working. After that, the precision control of the kneading and drying parts of the entire post-processing process is completed.

[0040] In order to better understand the method mentioned in this application, the present application also provides a system, which includes: The capture module is used to obtain the first hand activity and the second hand activity.

Initial tea temperature The qualified rate of temperature difference ; Stop module: when the time result and the temperature result are both qualified, the stop module executes the operation of stopping the motion capture device, the temperature collector and the timer.

[0041] Among them, the first calculation module is data-connected with the second calculation module. During actual operation, the first calculation module and the second calculation module can operate independently, synchronously, or sequentially. At the same time, the first calculation module in this implementation is set in the timer, and the second calculation module is set in the temperature collector.
