[0070] This application provides a lens positioning method, device, and storage medium for a rotary optical lens assembly, used to achieve high-precision positioning of each lens in a rotary disk.

[0071] It should be noted that the lens positioning method for a rotating optical lens group provided in this application can be applied to terminals as well as servers. For example, the terminal can be a smartphone, computer, tablet, smart TV, smartwatch, portable computer terminal, or a desktop computer or other fixed terminal. For ease of explanation, this application uses a terminal as the implementing entity for illustrative purposes.

[0072] Please refer to Figures 1 and 6. Figure 1 shows an embodiment of a lens positioning method for a rotary optical lens assembly provided in this application. The rotary optical lens assembly is connected to a turntable via a rotating shaft. The rotary optical lens assembly includes at least two lenses arranged circumferentially. At least two marker strips of different lengths are embedded in the outer side of the turntable at positions corresponding to the at least two lenses. A sensor is fixed to the turntable. The structure of the rotary optical lens assembly is shown in Figure 6. The method includes:

[0073] 101. Obtain the positional relationship between the sensor and the first marker bar;

[0074] In this embodiment, the positional relationship between the sensor and the first marker bar is obtained. The positional relationship between the sensor and the first marker bar includes: the sensor is located on the first marker bar, and the sensor is not located on the first marker bar. If it is determined that the sensor is not located on the first marker bar, then step 102 is executed.

[0075] 102. Determine whether the sensor is located on the first marker bar;

[0076] In this embodiment, it is determined whether the sensor is located on the first marker bar. If so, step 103 is executed.

[0077] 103. If the sensor is not located on the first marker bar, the control turntable drives the sensor to rotate along the first direction to the starting point of the first marker bar;

[0078] In this embodiment, if the sensor is not located on the first marker bar, the control turntable drives the sensor to rotate clockwise to the starting point of the first marker bar.

[0079] 104. Control the sensor to rotate from the starting point of the first marker bar along the first direction to the ending point of the first marker bar;

[0080] In this embodiment, the sensor is controlled by a turntable to rotate along the first direction to the starting point of the first marker bar and then to the ending point of the first marker bar. When the sensor senses the starting point of the first marker bar, the sensor starts timing. When the sensor rotates to the ending point of the first marker bar, the sensing disappears and the sensor stops timing.

[0081] 105. When the sensor rotates to the end of the first marker bar, the control turntable stops rotating and the first time required for the sensor to pass through the first marker bar is obtained;

[0082] In this embodiment, when the sensor rotates to the end of the first marker bar, the control turntable stops rotating, and the first time required for the sensor to pass through the first marker bar is obtained based on the sensor's timing duration.

[0083] 106. Determine the first lens corresponding to the first marker bar based on the first duration, and determine the first position of the first lens;

[0084] In this embodiment, when the sensor rotation speed remains constant, the first time taken to pass through the first marker strip is determined by the length of the first marker strip. Therefore, the first lens corresponding to the first marker strip can be determined based on the length of the first marker strip, and the first position of the first lens can be determined. The specific determination method will be described in detail in the next embodiment, and will not be repeated here.

[0085] 107. Control the turntable to drive the sensor to rotate along the first direction to the starting point of the second marker strip, determine the second lens corresponding to the second marker strip according to the second time required for the sensor to pass through the second marker strip, and determine the second position of the second lens;

[0086] In this embodiment, the rotary optical lens assembly includes at least two lenses, each corresponding to at least two marker strips of different lengths. The control turntable drives the sensor to continue rotating along the first direction to the starting point of the second marker strip. The second time required for the sensor to pass through the entire second marker strip is determined to identify the second lens corresponding to the second marker strip and to determine the second position of the second lens. It is understood that this application's solution is not only applicable to rotary optical lens assemblies with only two lenses. For example, this application's solution can be applied to an optical wheel-type lens assembly with six lenses, each corresponding to one of six marker strips of different lengths. The sensor passes through each of the six marker strips of different lengths to obtain the six... The six lenses and their positions are determined according to six different durations. The number of lenses included in the rotary optical lens group to which this application solution is specifically applicable is not limited. The sensor can be a through-beam photoelectric switch, the first marker strip can be a first-length edge strip, and the second marker strip can be a second-length edge strip; or, the sensor can be a Hall element, the first marker strip can be a first-length magnet, and the second marker strip can be a second-length magnet; or, the sensor can be a capacitive sensor or an inductive sensor, the first marker strip can be a first-length metal strip, and the second marker strip can be a second-length metal strip, wherein the materials of the first and second length metal strips are different from the material of the rotary disk.

[0087] This application uses a sensor and a first marker strip to determine the first lens corresponding to the first marker strip and the first position of the first lens, and uses a second marker strip to determine the second lens corresponding to the second marker strip and the second position of the second lens. This enables high-precision positioning of each lens in the turntable. Furthermore, the first lens identified by the first marker strip and the second lens identified by the second marker strip can automatically switch between multiple lenses in a rotary optical lens group as needed, thereby reducing the cost of automatic switching of optical lenses. In addition, the structure of this application is relatively easy to debug, effectively reducing costs without affecting the motion control accuracy. At the same time, because it does not require a motor with a built-in closed-loop control system, it can also reduce the space occupied by the motor.

[0092] In this embodiment, if the sensor is located on the first marker bar, step 230 is executed; if the sensor is located on the first marker bar, step 204 is executed.

[0093] 203. If the sensor is located on the first marker bar, the control turntable drives the sensor to rotate in the second direction to the starting point of the first marker bar;

[0094] In this embodiment, if the sensor is located on the first marker bar, the control turntable drives the sensor to rotate counterclockwise to the starting point of the first marker bar.
