Pointer calibration method of touch screen-based pointer type intelligent clock and application system

The invention discloses a pointer calibration method of touch screen-based pointer type intelligent clock and application system. According to the pointer calibration method, a clock MCU module can obtain a real position of the physical pointer dial at present; after synchronization adjustment, the internal time of the clock MCU module is consistent with the real indication time of the pointer. Time service is provided after pointer calibration, therefore, the accuracy of time service is further ensured. In the step of touching and calibration, a user only needs to dial a pointer on a touch screen to make a position of a physical pointer. The whole process is full of interactivity and amusement, and experience degree is lifted.
