Problems solved by technology

With the rise of smart devices, there are gradually automatic time synchronization methods, but the automatic time synchronization method is generally limited to electronic watches.
The reason is that watches with quartz movement or mechanical movement are mechanically controlled, and there is no feedback on the position of the pointer relative to the dial. Therefore, even if an intelligent module is installed on the quartz movement or mechanical movement, it is impossible to know where the pointer is currently pointing.

Embodiment 1

[0021] Use the image analysis software of the mobile phone to take pictures of the dial of the watch. The image analysis software not only obtains the image of the dial, but also records the actual time t1 of the photo, such as t1 is 5:3:20, and stores the actual time t1 in in the memory module of the mobile phone.

[0022] The image analysis software analyzes the acquired image to obtain the display time t2 of the dial, for example, t2 is 5 hours, 2 minutes and 55 seconds, and the display time t2 is stored in the storage module of the mobile phone.

[0023] The image analysis software calculates the time difference Δt=t1-t2=25 seconds.

[0024] The mobile phone transmits the time difference of 25s to the watch through the wireless communication module. After receiving the time difference, the controller of the watch adjusts the pointer and starts timing from 0 at the same time. The time threshold T=30 seconds is stored in the controller, then the adjustment amount is Δt+T, t...

Embodiment 2

[0027] Use the image analysis software of the mobile phone to take pictures of the dial of the watch. The image analysis software not only obtains the image of the dial, but also records the actual time t1 of the photo, such as t1 is 5:3:20, and stores the actual time t1 in in the memory module of the mobile phone.

[0028] The image analysis software analyzes the acquired image to obtain the display time t2 of the dial, for example, t2 is 5 hours, 5 minutes and 20 seconds, and the display time t2 is stored in the storage module of the mobile phone.

[0029] The image analysis software calculates the time difference Δt=t1-t2=-120 seconds.

[0030] The mobile phone transmits the time difference of 25s to the watch through the wireless communication module. After receiving the time difference, the controller of the watch adjusts the pointer and starts timing from 0 at the same time. The time threshold T=30 seconds is stored in the controller, then the adjustment amount is Δt+T,...

Abstract

A method for time-setting a watch through image recognition. The method includes the following steps: step 1, image acquisition of the dial of the watch; step 2, analyzing the acquired image to obtain the Describe the display time of the dial when the image is acquired; step 3, compare the display time in the step 2 with the actual time of the image acquisition in the step 1, and obtain the time difference; step 4, according to the step 3 In the time difference, adjust the hands of the watch. Through the above technical solution, the user only needs to take pictures of the dial with the mobile phone, and transmit the processed data to the watch, and the watch can automatically adjust the time.

Description

technical field [0001] The invention relates to a method for time-setting a watch, in particular to a method for time-setting a watch through image recognition. Background technique [0002] The current watch time is generally observed by human eyes, and if there is a difference with the network time, manual adjustment is performed. With the rise of smart devices, there are gradually automatic time-setting methods, but the automatic time-setting method is generally limited to electronic watches. The reason is that watches with quartz movement or mechanical movement are mechanically controlled, and there is no feedback on the position of the pointer relative to the dial. Therefore, even if an intelligent module is installed on the quartz movement or mechanical movement, it is impossible to know where the pointer is currently pointing. . Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention sets a controller in t...
