Example 6:
based on the method described in embodiment 1, in the following, some of the various implementations included in embodiment 1 will be specifically described in combination with specific implementation details, and the description of how to solve the offset angle of each pointer will be focused on the algorithm side. In this embodiment, the smart terminal is embodied as a smart phone. The method is characterized in that a scanning mode is adopted instead of photographing identification, one main reason is that photographing identification needs to be triggered by a user actively, and the user can only perform identification attempt once under the condition of active triggering, once the identification is not clear, the user experience is poor, in addition, as a watch is generally worn on the hand, the other hand of the user operates a mobile phone, the user experience and the intelligence degree can be greatly improved by adopting the scanning mode under the conditions that the screen of the mobile phone is increasingly large and focusing and photographing are almost impossible to operate by one hand. The specific image processing algorithm flow contained therein refers to the flow shown in fig. 7. The overall procedure is set forth below:
the first step is as follows: a user's scanning interface is aligned with the watch dial for scanning, the center of a circle of the dial and the position of 12 points are overlapped with the virtual position of the mobile phone end as much as possible, and the smart phone end can automatically select a picture with clear images and send the picture into a subsequent program for processing. Wherein, the scanning process is finished, and what the smart phone presents to the user is to wait for a moment to correct the progress bar.
The second step is that: the color image is converted to a grayscale image and then top-hat transformed (i.e., the grayscale image minus the on-operated image) in order to extract useful information in addition to the background. Moreover, the top hat transformation can be performed according to different background lights, so that the situation that some dark background places are lost during binarization is prevented, and then binarization processing is performed to obtain the graph 9.
The third step: the method is mainly used for dividing the pointer from the image, the method is used for calculating the maximum connected domain in the image (because the pointer is connected around a shaft, the method is particularly good in effect), the maximum connected domain is that the outline is searched for the graph firstly, then the maximum outline is the maximum connected domain, meanwhile, the center of a circle of the pointer is obtained according to the pointer shaft, the center of the circle is the center of a circle of a pointer coordinate system, the method plays an important role in accurately calculating the angle of the subsequent pointer, and meanwhile, the method plays a role in judging the straight line, and is shown in figure 10.
The fourth step: the straight line of the image is detected by using Hough transform, and the noise interference can be better reduced by finding the straight line through Hough transform compared with other methods. The method comprises the following steps: a straight line is a set of a series of discrete points in an image, and through a discrete polar coordinate formula of the straight line, a geometric equation of the discrete points of the straight line can be expressed as follows: x cos (theta) + y sin (theta) ═ r, where angle theta refers to the angle between r and the X axis, and r is the geometric perpendicular distance to the line. Any point x, y on a straight line can be expressed where r, theta are constants. The formula is graphically represented as shown in fig. 11.
However, in the field of image processing implemented, the pixel coordinates P (x, y) of the image are known, and r, theta are the variables we are looking for. If we can plot each (r, theta) value from the pixel point coordinate P (x, y) value, we convert from the image cartesian coordinate system to the polar hough space system, and this point-to-curve transformation is called the hough transformation of straight lines. The transform equally divides or accumulates the grid for a finite interval of values by quantizing the hough parameter space. When the hough transform algorithm starts, each pixel coordinate point P (x, y) is transformed to the upper surface of the curve point of (r, theta), and is accumulated to the corresponding grid data point, when a peak appears, it indicates that a straight line exists, and the detection result is as shown in fig. 12, where the first and last points of the straight line are detected at the marked position in fig. 12. And judging the hour hand, the minute hand and the second hand according to the length of the straight line.
The fifth step: according to three linear equations obtained by hough transform, the corresponding angle can be calculated by using an inverse triangle, and the time can be calculated by using the angle, for example, the hour hand is 275 °, so that the hour is obtained:
(must be rounded in hours)
The calculation formulas of the minute hand and the second hand can be obtained in turn:
those of ordinary skill in the art will appreciate that all or part of the steps of the various methods of the embodiments may be implemented by associated hardware as instructed by a program, which may be stored on a computer-readable storage medium, which may include: a Read Only Memory (ROM), a Random Access Memory (RAM), a magnetic or optical disk, or the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.

the camera is used for scanning the dial plate of the intelligent watch, recording the current information of the hand and/or the dial plate of the intelligent watch by using the memory, intercepting one or more images containing the current information of the hand and/or the dial plate of the intelligent watch, and performing target identification on the hour hand, the minute hand and/or the second hand by using the called information of the hand and the dial plate under the model of the intelligent watch;
the processor is used for calling corresponding pointer information and dial plate information stored in the memory according to the model of the intelligent watch, performing target identification on an hour hand, a minute hand and/or a second hand by using the called pointer information and dial plate information under the model of the intelligent watch, analyzing the intelligent watch hand and/or dial plate information, acquiring current intelligent watch time information, analyzing an image A containing the intelligent watch hand and/or dial plate information by the intelligent terminal, acquiring current intelligent watch time information, and calling an intercepted and acquired image B for analysis if the current acquired intelligent watch time information is judged to be not satisfactory;
if the acquired time information of the intelligent watch does not meet the requirements, the intelligent terminal controls the dial plate of the intelligent watch to change the brightness, so that the image of the pointer and/or dial plate information of the intelligent watch intercepted after adjustment can be analyzed and acquired, the watch time information meeting the requirements is recorded, the scanning time is used for being combined with the time consumed by analyzing the pointer and/or dial plate information of the intelligent watch, the delay time for analysis is calculated, the network standard time, the current time of the intelligent watch and the delay time are corrected, the correction time difference is calculated and obtained, and the correction time difference is sent to the intelligent watch by using a data interface;
and the network interface is used for providing an interface for the processor to acquire the network standard time.
