Method for calibrating a watch by image recognition

This case relates to an image recognition method, and more particularly to a method for calibrating a watch by image recognition.

In general, traditional pointer watches do not have the function of automatically calibrating the hands or movements, so users often need to manually adjust the pointer to the correct position.

Although there is a radio wave watch on the market, it can perform time calibration by receiving radio waves. However, in a remote area or a poor signal area, the position of the pointer cannot be effectively calibrated because the radio wave cannot be surely received. On the other hand, although in recent years, watch products using the GPS to perform pointer calibration have been developed, the installation of the GPS receiver in the watch causes rapid consumption of battery power and increases the overall volume of the watch, and also increases the number of watches. The manufacturing cost of the watch. In addition, some watch products that receive the GPS signal in this way perform pointer calibration by driving the gear reducer. If the feedback method is not set, the position of the pointer cannot be ensured after the calibration.

Therefore, how to develop a method for calibrating a watch by image recognition, which can reduce power loss and effectively reduce product volume and manufacturing cost, is still a problem to be solved.

The main purpose of the present invention is to provide a method for calibrating a watch by image recognition, which solves the problem that the conventional pointer calibration is limited by geographical factors, causing a large loss of power, and the product volume and manufacturing cost are high.

Another object of the present invention is to provide a method for calibrating a watch by image recognition, by performing image capture on a watch by a portable communication device, and performing alignment by analyzing the captured image, thereby performing calibration, or not Limited by any geographical environment factors, it can effectively reduce power loss and achieve the effects of reducing product volume and reducing manufacturing costs.
