Description

光圈控制方法、装置、光圈设备和拍摄设备Aperture control method, device, aperture device, and photographing device

技术领域Technical field

本发明涉及拍摄技术领域，尤其涉及一种光圈控制方法、装置、光圈设备和拍摄设备。The present invention relates to the field of photographing technology, and in particular, to a method, a device, an aperture device, and a photographing device for controlling an aperture.

背景技术Background technique

镜头内部通常设置有光圈，用于控制透过镜头进入相机内感光面的光量的大小。光圈大小采用光圈值进行表示。An aperture is usually provided inside the lens to control the amount of light that passes through the lens and enters the photosensitive surface in the camera. The aperture size is expressed by the aperture value.

光圈装置通常包括光圈控制器和光圈驱动机构两大部分。光圈控制器根据接收到的命令，通过光圈驱动机构改变光圈中叶片的位置，从而改变叶片形成的孔状光栅的面积，达到改变通光量的目的。光圈驱动机构存在加工、装配、工作形变等误差，导致光圈控制的准确度受到一定限制。The aperture device usually includes two parts: an aperture controller and an aperture driving mechanism. According to the received command, the aperture controller changes the position of the blade in the aperture through the aperture driving mechanism, thereby changing the area of the hole-shaped grating formed by the blade, so as to change the amount of light. The aperture driving mechanism has errors in processing, assembly, and work deformation, which causes the accuracy of the aperture control to be limited.

目前，为了提高光圈控制的准确度，可以减小光圈驱动机构加工、装配、工作形变等误差来实现。但是，误差每减小一个数量级，都会带来光圈装置制造成本的急剧上升。并且，误差的减小也存在极限，导致光圈控制的准确度较低。At present, in order to improve the accuracy of the aperture control, it can be achieved by reducing errors such as processing, assembly, and work deformation of the aperture drive mechanism. However, reducing the error by an order of magnitude leads to a sharp rise in the manufacturing cost of the aperture device. In addition, there is a limit to the reduction of errors, resulting in a lower accuracy of the aperture control.

图1为本发明实施例一提供的光圈控制方法的流程图。本实施例提供的光圈控制方法，执行主体可以为光圈控制器，所述光圈控制器可以设置在光圈设备中。如图1所示，本实施例提供的光圈控制方法，可以包括：FIG. 1 is a flowchart of an aperture control method according to a first embodiment of the present invention. In the aperture control method provided in this embodiment, an execution body may be an aperture controller, and the aperture controller may be provided in an aperture device. As shown in FIG. 1, the aperture control method provided in this embodiment may include:

The aperture drive mechanism usually includes a motor. This embodiment does not limit the specific structures of the aperture driving mechanism and the aperture blade. This embodiment does not limit the type of the motor. The motor can move the aperture blades at a certain speed, so as to adjust the aperture value. When the aperture formed by the aperture blade becomes larger, the aperture value of the aperture device becomes smaller. When the aperture formed by the aperture blade becomes smaller, the aperture value of the aperture device becomes larger. In this embodiment, the target aperture value indicates the size of the aperture value desired to be set. The speed value of the motor indicates the speed of the motor during the process of adjusting the aperture value. After obtaining the aperture setting instruction, the motor can be controlled to move at the speed of the motor, thereby adjusting the aperture value of the aperture device to the target aperture value.

需要说明的是，本实施例对于目标光圈值和电机的速度值的具体取值不做限定。It should be noted that, in this embodiment, specific values of the target aperture value and the speed value of the motor are not limited.

需要说明的是，本实施例对于目标光圈值和电机的速度值的获取方式不做限定。可选的，目标光圈值和电机的速度值可以为用户输入的。可选的，目标光圈值和电机的速度值可以为拍摄设备中的控制器输出给光圈设备的。本实施例对于拍摄设备中的控制器如何获得目标光圈值和电机的速度值不做限定，可以采用现有的算法。It should be noted that, in this embodiment, a method for acquiring the target aperture value and the speed value of the motor is not limited. Optionally, the target aperture value and the speed of the motor may be entered by the user. Optionally, the target aperture value and the speed value of the motor may be output to the aperture device by a controller in the shooting device. This embodiment does not limit how the controller in the shooting device obtains the target aperture value and the speed value of the motor, and an existing algorithm may be used.

S102、根据目标光圈值、电机的速度值和预设的光圈特征数据确定电机的目标电机位置。S102. Determine a target motor position of the motor according to the target aperture value, the speed value of the motor, and preset aperture characteristic data.

其中，预设的光圈特征数据可以包括：多个预设电机位置，电机的多个预设速度值和多个光圈值。光圈值为电机以预设速度值运动到预设电机位置时对应的光圈值。The preset aperture characteristic data may include multiple preset motor positions, multiple preset speed values and multiple aperture values of the motor.

可选的，目标电机位置为电机以电机的速度值运动时使得光圈值为目标光圈值时的电机位置。Optionally, the target motor position is a motor position when the motor moves at the speed value of the motor such that the aperture value is the target aperture value.

具体的，预设的光圈特征数据可以预先存储在存储器中。光圈控制器可以从存储器中获取预设的光圈特征数据。本实施例对于存储器的类型和位置不做限定。可选的，存储器可以为设置在光圈设备中的存储器。可选的，存储器可以为设置在光圈控制器中的存储器。在调整光圈值大小的过程中，为了使光圈设备的光圈值为期望设置的光圈值，电机将最终运动到一个位置。在本实施例中，可以根据目标光圈值、电机的速度值和预设的光圈特征数据确定电机的目标电机位置。这样，电机以电机的速度值运动到所述目标电机位置时，可以将光圈设备的光圈值调整到目标光圈值。Specifically, the preset aperture characteristic data may be stored in a memory in advance. The aperture controller can obtain preset aperture characteristic data from the memory. This embodiment does not limit the type and location of the memory. Optionally, the memory may be a memory provided in the aperture device. Optionally, the memory may be a memory provided in the aperture controller. In the process of adjusting the aperture value, in order to make the aperture value of the aperture device the desired aperture value, the motor will eventually move to a position. In this embodiment, the target motor position of the motor may be determined according to the target aperture value, the speed value of the motor, and preset aperture characteristic data. In this way, when the motor moves to the target motor position at the speed value of the motor, the aperture value of the aperture device can be adjusted to the target aperture value.

光圈设备中的光圈驱动机构在加工、装配、工作形变时存在误差，导致光圈控制的准确性较低。在本实施例中，根据目标光圈值和电机的速度值确定目标电机位置时，考虑了预设的光圈特征数据。由于预设的光圈特征数据可以反映出电机位置、电机的速度值与光圈值之间的准确的对应关系，因此，提高了确定电机的目标电机位置的准确性，进而提高了光圈控制的准确性。There is an error in the aperture driving mechanism of the aperture device during processing, assembly, and work deformation, resulting in a lower accuracy of the aperture control. In this embodiment, when determining the target motor position according to the target aperture value and the speed value of the motor, preset aperture characteristic data is considered. Since the preset aperture characteristic data can reflect the accurate correspondence between the motor position, the speed value of the motor, and the aperture value, the accuracy of determining the target motor position of the motor is improved, and the accuracy of the aperture control is improved. .

需要说明的是，本实施例对于预设电机位置、预设速度值和光圈值的具体取值不做限定，可以是对出厂前的光圈设备进行测量获得的数据，并预先存储在光圈设备中设置的存储器中。可选的，可以根据用户经常设置的目标光圈值和电机的速度值，通过大数据分析的方法确定预设电机位置和预设速度值。可选的，多个预设电机位置可以均匀覆盖电机位置的取值范围，多个预设速度值可以均匀覆盖电机的速度值的取值范围。可选的，利用出厂前的光圈设备，控制电机以预设速度值运动到预设电机位置时，使用光圈面积计或者其他仪器测量得到对应的光圈值。It should be noted that the specific values of the preset motor position, preset speed value, and aperture value are not limited in this embodiment, and may be data obtained by measuring the aperture device before leaving the factory and stored in the aperture device in advance. Set in memory. Optionally, the preset motor position and the preset speed value can be determined by a method of big data analysis according to the target aperture value and the speed value of the motor that are often set by the user. Optionally, multiple preset motor positions can evenly cover the value range of the motor position, and multiple preset speed values can even cover the value range of the motor's speed value. Optionally, when the aperture device before the factory is used, when the control motor is moved to the preset motor position at a preset speed value, the corresponding aperture value is measured using an aperture area meter or other instruments.

需要说明的是，存储器的存储空间有限，存储器中预先存储的光圈特征数据，可以为测量得到的所有光圈特征数据中的一部分。当需要根据预设的光圈特征数据确定目标电机位置时，可以基于预设的光圈特征数据采用插值的方法获得更多的光圈特征数据。It should be noted that the storage space of the memory is limited, and the aperture feature data stored in the memory in advance may be a part of all the aperture feature data obtained through measurement. When the target motor position needs to be determined according to the preset aperture feature data, more aperture feature data can be obtained by interpolation based on the preset aperture feature data.

下面通过表1详细说明预设的光圈特征数据。The preset aperture characteristic data is described in detail below through Table 1.

表1Table 1

在表1中，Pos表示预设电机位置。具体的，Pos 0…Pos N表示N+1个预设电机位置。Speed表示电机的预设速度值。具体的，Speed 0…Speed M表示电机的M+1个预设速度值。Val表示光圈值。具体的，Val _Pos _{i_Speed} _j表示电机以预设速度值Speed j运动到预设电机位置Pos i时对应的光圈值，0≤i≤N，0≤j≤M。例如，Val _Pos _{1_Speed} _M表示电机以预设速度值Speed M运动到预设电机位置Pos 1时对应的光圈值。又例如，Val _Pos _{N_Speed} ₁表示电机以预设速度值Speed 1运动到预设电机位置PosN时对应的光圈值。 In Table 1, Pos indicates the preset motor position. Specifically, Pos 0 ... Pos N represents N + 1 preset motor positions. Speed indicates the preset speed value of the motor. Specifically, Speed 0 ... Speed M represents M + 1 preset speed values of the motor. Val is the aperture value. Specifically, Val _Pos _{i_Speed} _j represents a corresponding aperture value when the motor moves at a preset speed value Speed j to a preset motor position Pos i, 0 ≦ i ≦ N, 0 ≦ j ≦ M. For example, Val _Pos _{1_Speed} _M represents the corresponding aperture value when the motor moves at a preset speed value Speed M to a preset motor position Pos 1. For another example, Val _Pos _{N_Speed} ₁ represents a corresponding aperture value when the motor moves at a preset speed value Speed 1 to a preset motor position PosN.

S103、控制电机以速度值运动到目标电机位置。S103. The control motor moves to a target motor position at a speed value.

可见，本实施例提供的光圈控制方法，在获取目标光圈值和电机的速度值之后，可以根据目标光圈值、电机的速度值和预设的光圈特征数据确定电机的目标电机位置，从而，电机以电机的速度值运动到目标电机位置时，可以将光圈设备的光圈值调整到目标光圈值。由于预设的光圈特征数据可以反映出电机位置、电机的速度值与光圈值之间的准确的对应关系，因此，提高了确定目标电机位置的准确性，进而提高了光圈控制的准确性。而且，避免了减小光圈驱动机构加工、装配、工作形变等误差，降低了硬件实现难度，降低了光圈设备的成本。It can be seen that after obtaining the target aperture value and the speed value of the motor, the aperture control method provided in this embodiment may determine the target motor position of the motor according to the target aperture value, the speed value of the motor, and preset aperture characteristic data. When moving to the target motor position with the speed value of the motor, the aperture value of the aperture device can be adjusted to the target aperture value. Since the preset aperture characteristic data can reflect the accurate correspondence between the motor position, the speed value of the motor and the aperture value, the accuracy of determining the target motor position is improved, and the accuracy of the aperture control is improved. In addition, errors such as processing, assembling, and working deformation of the aperture driving mechanism are reduced, the difficulty of hardware implementation is reduced, and the cost of the aperture equipment is reduced.

可选的，光圈特征数据还可以包括光圈移动方向。光圈移动方向包括使光圈值变大和/或变小的方向。例如，光圈值从f/1.4调整为f/2时电机的运动方向即为使光圈值变大的方向。此时，光圈叶片形成的通光孔变小。反之，光圈值从f/2调整为f/1.4时电机的运动方向即为使光圈值变小的方向。此时，光圈叶片形成的通光孔变大。光圈值具体为电机按照光圈移动方向以预设速度值运动到预设电机位置时对应的光圈值。Optionally, the aperture characteristic data may further include an aperture movement direction. The aperture movement direction includes a direction in which the aperture value becomes larger and / or smaller. For example, when the aperture value is adjusted from f / 1.4 to f / 2, the direction of movement of the motor is the direction in which the aperture value becomes larger. At this time, the through-hole formed by the diaphragm blade becomes smaller. Conversely, when the aperture value is adjusted from f / 2 to f / 1.4, the direction of movement of the motor is the direction in which the aperture value becomes smaller. At this time, the through-hole formed by the diaphragm blade becomes larger. The aperture value is specifically the aperture value when the motor moves to the preset motor position at a preset speed value according to the direction of the aperture movement.

下面通过示例进行说明。The following uses examples to illustrate.

表2示出了使光圈值变大的方向对应的光圈特征数据。表3示出了使光圈值变小的方向对应的光圈特征数据。Table 2 shows the aperture characteristic data corresponding to the direction in which the aperture value is increased. Table 3 shows the aperture characteristic data corresponding to the direction in which the aperture value becomes smaller.

表2(光圈值变大的方向)Table 2 (the direction in which the aperture value becomes larger)

表3(光圈值变小的方向)Table 3 (Aperture direction becomes smaller)

相比于表1，在表2中，Val表示光圈值。具体的，Val _Pos _{i_Speed} _{j_OC}表示电机按照使光圈值变大的方向，以预设速度值Speed j运动到预设电机位置Pos i时对应的光圈值。 Compared to Table 1, in Table 2, Val represents an aperture value. Specifically, Val _Pos _{i_Speed} _{j_OC} represents a corresponding aperture value when the motor moves at a preset speed value Speed j to a preset motor position Pos i in a direction of _increasing the aperture value.

相比于表1，在表3中，Val表示光圈值。具体的，Val _Pos _{i_Speed} _{j_CO}表示电机按照使光圈值变小的方向，以预设速度值Speed j运动到预设电机位置Pos i时对应的光圈值。 Compared to Table 1, in Table 3, Val represents the aperture value. Specifically, Val _Pos _{i_Speed} _{j_CO} represents a corresponding aperture value when the motor moves at a preset speed value Speed j to a preset motor position Pos i in a direction that makes the aperture value smaller.

需要说明的是，由于光圈驱动机构加工、装配、工作形变等误差，光圈移动方向不同时，电机按照光圈移动方向以相同的预设速度值运动到相同的预设电机位置时对应的光圈值，可能相同，也可能不相同。通过具体示例进行说明。表2中的Val _Pos _{N_Speed} _{1_OC}与表3中的Val _Pos _{N_Speed} _{1_CO}可能相同。表2中的Val _Pos _{1_Speed} _{M_OC}与表3中的Val _Pos _{1_Speed} _{M_CO}可能不同。 It should be noted that due to errors in the processing, assembly, and work deformation of the aperture drive mechanism, when the aperture movement direction is different, the corresponding aperture value when the motor moves at the same preset speed value according to the aperture movement direction to the same preset motor position. May be the same or different. Explain with specific examples. In Table ₂ _Val _Pos N_Speed 1_OC in Table 3 may be the same _{_Val} _Pos N_Speed 1_CO. In Table ₂ _Val _Pos 1_Speed M_OC in Table 3 _{_Val} _Pos 1_Speed M_CO may be different.

可选的，若目标光圈值大于当前光圈值，S102中，预设的光圈特征数据具体为与光圈移动方向为使光圈值变大的方向对应的光圈特征数据。Optionally, if the target aperture value is greater than the current aperture value, in S102, the preset aperture feature data is specifically the aperture feature data corresponding to the direction in which the aperture movement direction is to make the aperture value larger.

可选的，若目标光圈值小于当前光圈值，S102中，预设的光圈特征数据具体为与光圈移动方向为使光圈值变小的方向对应的光圈特征数据。Optionally, if the target aperture value is smaller than the current aperture value, in S102, the preset aperture feature data is specifically aperture feature data corresponding to a direction in which the aperture movement direction is made smaller.

具体的，如果目标光圈值大于当前光圈值，说明需要将光圈设备的光圈值调大。因此，在确定目标点击位置时，需要根据使光圈值变大的方向对应的光圈特征数据。如果目标光圈值小于当前光圈值，说明需要将光圈设备的光圈值调小。因此，在确定目标点击位置时，需要根据使光圈值变小的方向对应的光圈特征数据。Specifically, if the target aperture value is greater than the current aperture value, it means that the aperture value of the aperture device needs to be increased. Therefore, when determining the target click position, it is necessary to use the aperture characteristic data corresponding to the direction in which the aperture value becomes larger. If the target aperture value is smaller than the current aperture value, it means that the aperture value of the aperture device needs to be reduced. Therefore, when determining the target click position, it is necessary to use the aperture characteristic data corresponding to the direction in which the aperture value becomes smaller.

通过在确定目标电机位置时考虑光圈移动方向对应的光圈特征数据，进一步提升了确定目标电机位置的准确性，提升了光圈控制的准确性。By considering the aperture characteristic data corresponding to the direction of aperture movement when determining the position of the target motor, the accuracy of determining the position of the target motor is further improved, and the accuracy of the aperture control is improved.

本实施例提供一种光圈控制方法，包括：获取光圈设置指令，根据目标光圈值、电机的速度值和预设的光圈特征数据确定电机的目标电机位置，控制电机以速度值运动到目标电机位置。本实施例提供的光圈控制方法，由于预设的光圈特征数据可以反映出电机位置、电机的速度值与光圈值之间的准确的对应关系，根据目标光圈值、电机的速度值和预设的光圈特征数据确定电机的目标电机位置，提高了确定目标电机位置的准确性，进而提高了光圈控制的准确性。并且，降低了硬件实现难度，降低了光圈设备的成本。This embodiment provides an aperture control method, including: acquiring an aperture setting instruction, determining a target motor position of the motor according to a target aperture value, a motor speed value, and preset aperture characteristic data, and controlling the motor to move to the target motor position at a speed value . According to the aperture control method provided in this embodiment, the preset aperture characteristic data can reflect the accurate correspondence between the motor position, the speed value of the motor, and the aperture value. According to the target aperture value, the speed value of the motor, and the preset The aperture characteristic data determines the target motor position of the motor, which improves the accuracy of determining the target motor position, and further improves the accuracy of the aperture control. In addition, the hardware implementation difficulty is reduced, and the cost of the aperture device is reduced.

图2为本发明实施例二提供的光圈控制方法的流程图。本实施例在图1所示实施例一的基础上，提供了光圈控制方法的一种具体实现方式，具体提供了S102的一种实现方式。如图2所示，本实施例提供的光圈控制方法，S102中，根据目标光圈值、速度值和预设的光圈特征数据确定电机的目标电机位置，可以包括：FIG. 2 is a flowchart of an aperture control method according to a second embodiment of the present invention. Based on the first embodiment shown in FIG. 1, this embodiment provides a specific implementation manner of the aperture control method, and specifically provides an implementation manner of S102. As shown in FIG. 2, in the aperture control method provided in this embodiment, in S102, determining a target motor position of a motor according to a target aperture value, a speed value, and preset aperture characteristic data may include:

S201、若多个预设速度值不包括电机的速度值，则根据光圈特征数据进行插值，获得电机以电机的速度值运动时电机位置与光圈值之间的对应关系。S201. If the plurality of preset speed values do not include the speed value of the motor, perform interpolation based on the aperture characteristic data to obtain the correspondence between the motor position and the aperture value when the motor moves at the speed value of the motor.

S202、根据电机位置与光圈值之间的对应关系，确定目标光圈值对应的目标电机位置。S202. Determine the target motor position corresponding to the target aperture value according to the corresponding relationship between the motor position and the aperture value.

具体的，预设的光圈特征数据仅包括了有限数目的预设速度值、预设电机位置和光圈值。多个预设速度值可能包括电机的速度值，也可能不包括电机的速度值。当多个预设速度值不包括电机的速度值时，需要以预设的光圈特征数据为基础进行插值，获得电机以电机的速度值(标记为Speed X)运动时对应的电机位置与光圈值之间的对应关系。可选的，所述对应关系可以为以电机位置为自变量，以光圈值为因变量的函数关系。可选的，所述对应关系可以为以光圈值为自变量，以电机位置为因变量的函数关系。从而，可以根据该对应关系获得Val＝Y(目标光圈值)时对应的目标电机位置(标记为Pos Y)。Specifically, the preset aperture characteristic data includes only a limited number of preset speed values, preset motor positions, and aperture values. The multiple preset speed values may or may not include the speed value of the motor. When multiple preset speed values do not include the speed value of the motor, it is necessary to perform interpolation based on the preset aperture characteristic data to obtain the corresponding motor position and aperture value when the motor moves at the speed value of the motor (labeled Speed X) Correspondence between. Optionally, the corresponding relationship may be a function relationship with the motor position as an independent variable and the aperture value as a dependent variable. Optionally, the corresponding relationship may be a function relationship with an aperture value as an independent variable and a motor position as a dependent variable. Therefore, the corresponding target motor position (labeled Pos Y) when Val = Y (target aperture value) can be obtained according to the corresponding relationship.

由于预设的光圈特征数据可以反映出预设电机位置、预设速度值与光圈值之间的准确的对应关系，因此，根据预设的光圈特征数据进行插值可以获得准确的电机位置与光圈值之间的对应关系，进而可以获得准确的目标电机位置，提升了光圈控制的准确性。Since the preset aperture characteristic data can reflect the accurate correspondence between the preset motor position, the preset speed value and the aperture value, the interpolation can be performed according to the preset aperture characteristic data to obtain an accurate motor position and aperture value.

下面通过示例对本实施例提供的光圈控制方法进行说明。The following describes the aperture control method provided by this embodiment through an example.

在一个示例中，目标光圈值大于当前光圈值。预设的光圈特征数据具体为光圈移动方向为使光圈值变大的方向对应的光圈特征数据。结合表2，本实施例提供的光圈控制方法，可以包括：In one example, the target aperture value is greater than the current aperture value. The preset aperture feature data is specifically aperture feature data corresponding to a direction in which the aperture movement direction is a direction in which the aperture value becomes larger. With reference to Table 2, the aperture control method provided in this embodiment may include:

步骤1：根据表2中每个Pos i对应的Speed j和Val _Pos _{i_Speed} _{j_OC}，通过插值获得每个Pos i对应的速度值-光圈值拟合曲线。并且，根据每个Pos i对应的速度值-光圈值拟合曲线，得到每个Pos i在Speed X(电机的速度值)下对应的实际光圈值Val _Pos _{i_Speed} _{X_OC}。 Step 1: According to the Speed j and Val _Pos _{i_Speed} _{j_OC} corresponding to each Pos i in Table 2, the speed-aperture value fitting curve corresponding to each Pos i is obtained by interpolation. And, according to the speed-aperture value fitting curve corresponding to each Pos i, the actual aperture value Val _Pos _{i_Speed} _{X_OC} corresponding to each Pos i under Speed X (speed value of the motor) is _obtained .

具体的，如表2所示，针对Pos 0，根据Pos 0对应的速度值(Speed 0…Speed M)和光圈值(Val _Pos _{0_Speed} _j…Val _Pos _{0_Speed} _j，0≤j≤M)，通过插值可以获得Pos 0对应的速度值-光圈值拟合曲线。根据该速度值-光圈值拟合曲线，可以获得当速度值为Speed X(电机的速度值)时对应的实际光圈值(标记为Val _Pos _{0_Speed} _{M_OC})。或者理解为获得了(Pos 0，Speed X，Val _Pos _{0_Speed} _{M_OC})数对。针对Pos 1，根据Pos 1对应的速度值(Speed 0…Speed M)和光圈值(Val _Pos _{1_Speed} _j…Val _Pos _{1_Speed} _j，0≤j≤M)，可以获得Pos 1对应的速度值-光圈值拟合曲线。根据该速度值-光圈值拟合曲线，可以获得当速度值为Speed X(电机的速度值)时对应的实际光圈值(标记为Val _Pos _{1_Speed} _{M_OC})。或者理解为获得了(Pos 1，Speed X，Val _Pos _{1_Speed} _{M_OC})数对。类似的，针对表2中的N+1个预设电机位置(Pos 0…Pos N)，可以获得N+1条速度值-光圈值拟合曲线和N+1个数对(Pos i，Speed X，Val _Pos _{i_Speed} _{M_OC})，0≤i≤N。这样，就得到了每个Pos i在Speed X(电机的速度值)下对应的实际光圈值Val _Pos _{i_Speed} _{X_OC}。 Specifically, as shown in Table 2, for Pos 0, according to the speed value (Speed 0 ... Speed M) and aperture value (Val _Pos _{0_Speed} _j ... Val _Pos _{0_Speed} _j , 0≤j≤M) corresponding to Pos 0, interpolation is performed. A speed-aperture value fitting curve corresponding to Pos 0 can be obtained. According to the speed value-aperture value fitting curve, the actual aperture value (labeled as Val _Pos _{0_Speed} _{M_OC} ) can be obtained when the speed value is Speed X (the speed value of the motor). Or it is understood that a pair of (Pos 0, Speed X, Val _Pos _{0_Speed} _{M_OC} ) is obtained. For Pos 1, according to the speed value (Speed 0 ... Speed M) and aperture value (Val _Pos _{1_Speed} _j ... Val _Pos _{1_Speed} _j , 0≤j≤M) corresponding to Pos 1, the speed value-aperture value corresponding to Pos 1 can be obtained Curve fitting. According to the speed value-aperture value fitting curve, the actual aperture value (labeled as Val _Pos _{1_Speed} _{M_OC} ) can be obtained when the speed value is Speed X (the speed value of the motor). Or it is understood that a pair of (Pos 1, Speed X, Val _Pos _{1_Speed} _{M_OC} ) is obtained. Similarly, for N + 1 preset motor positions (Pos 0 ... Pos N) in Table 2, N + 1 speed value-aperture value fitting curves and N + 1 number pairs (Pos i, Speed X, Val _Pos _{i_Speed} _{M_OC} ), 0 ≦ i ≦ N. In this way, the actual aperture value Val _Pos _{i_Speed} _{X_OC} corresponding to each Pos i under Speed X (speed value of the motor) is _obtained .

步骤2：根据每个Pos i及其对应的实际光圈值Val _Pos _{i_Speed} _{X_OC}，通过插值得到电机以Speed X(电机的速度值)运动时的电机位置-光圈值拟合曲线。并且，根据该电机位置-光圈值拟合曲线得到目标光圈值Y对应的目标电机位置Pos Y。 Step 2: According to each Pos i and its corresponding actual aperture value Val _Pos _{i_Speed} _{X_OC} , the motor position-aperture value fitting curve when the motor moves at Speed X (speed value of the motor) is obtained through interpolation. And, according to the motor position-aperture value fitting curve, the target motor position Pos Y corresponding to the target aperture value Y is obtained.

具体的，根据N+1个数对(Pos i，Speed X，Val _Pos _{i_Speed} _{M_OC})，通过插值可以获得电机以电机的速度值(Speed X)运动时的电机位置-光圈值拟合曲线。这样，根据该电机位置-光圈值拟合曲线，可以得到目标光圈值Y对应的目标电机位置Pos Y。 Specifically, according to N + 1 number pairs (Pos i, Speed X, Val _Pos _{i_Speed} _{M_OC} ), a motor position-aperture value fitting curve when the motor moves at the motor speed value (Speed X) can be obtained through interpolation. In this way, according to the motor position-aperture value fitting curve, the target motor position Pos Y corresponding to the target aperture value Y can be obtained.

步骤3：控制电机以Speed X运动到目标电机位置Pos Y。Step 3: Control the motor to move to the target motor position Pos Y at Speed X.

The preset aperture feature data is specifically aperture feature data corresponding to a direction in which the aperture movement direction is a direction in which the aperture value becomes smaller. With reference to Table 3, the aperture control method provided in this embodiment may include:

步骤1：根据表3中每个Pos i对应的Speed j和Val _Pos _{i_Speed} _{j_CO}，通过插值获得每个Pos i对应的速度值-光圈值拟合曲线。并且，根据每个Pos i对应的速度值-光圈值拟合曲线，得到每个Pos i在Speed X(电机的速度值)下对应的实际光圈值Val _Pos _{i_Speed} _{X_CO}。 Step 1: According to Speed j and Val _Pos _{i_Speed} _{j_CO} corresponding to each Pos i in Table 3, a speed-aperture value fitting curve corresponding to each Pos i is obtained by interpolation. And, according to the speed-aperture value fitting curve corresponding to each Pos i, the actual aperture value Val _Pos _{i_Speed} _{X_CO} corresponding to each Pos i under Speed X (speed value of the motor) is _obtained .

步骤2：根据每个Pos i及其对应的实际光圈值Val _Pos _{i_Speed} _{X_CO}，通过插值得到电机以Speed X(电机的速度值)运动时的电机位置-光圈值拟合曲线。并且，根据该电机位置-光圈值拟合曲线得到目标光圈值Y对应的目标电机位置Pos Y。 Step 2: According to each Pos i and its corresponding actual aperture value Val _Pos _{i_Speed} _{X_CO} , the motor position-aperture value fitting curve when the motor moves at Speed X (speed value of the motor) is obtained through interpolation. And, according to the motor position-aperture value fitting curve, the target motor position Pos Y corresponding to the target aperture value Y is obtained.

图3为本发明实施例三提供的光圈控制方法的流程图。本实施例在图1所示实施例一的基础上，提供了光圈控制方法的另一种具体实现方式，具体提供了S102的一种实现方式。如图3所示，本实施例提供的光圈控制方法，S102中，根据目标光圈值、速度值和预设的光圈特征数据确定电机的目标电机位置，可以包括：FIG. 3 is a flowchart of an aperture control method according to a third embodiment of the present invention. Based on the first embodiment shown in FIG. 1, this embodiment provides another specific implementation manner of the aperture control method, and specifically provides an implementation manner of S102. As shown in FIG. 3, in the aperture control method provided in this embodiment, in S102, determining a target motor position of a motor according to a target aperture value, a speed value, and preset aperture characteristic data may include:

S301、若多个预设速度值包括电机的速度值，确定与电机的速度值对应的光圈特征数据中是否包括目标光圈值。S301. If the multiple preset speed values include the speed value of the motor, determine whether the aperture characteristic data corresponding to the speed value of the motor includes the target aperture value.

S302、若与电机的速度值对应的光圈特征数据中包括目标光圈值，则将与电机的速度值和目标光圈值对应的预设电机位置确定为目标电机位置。S302. If the aperture characteristic data corresponding to the speed value of the motor includes the target aperture value, determine the preset motor position corresponding to the speed value and the target aperture value of the motor as the target motor position.

下面结合表1进行示例说明。An example is described below with reference to Table 1.

预设的光圈特征数据仅包括了有限数目的预设速度值、预设电机位置和光圈值。多个预设速度值(Speed 0…Speed M)包括电机的速度值(Speed X)。假设，Speed X＝Speed 1。则需要进一步确定与电机的速度值对应的光圈特征数据(Val _Pos _{i_Speed} ₁…Val _Pos _{i_Speed} ₁,0≤i≤N)中是否包括目标光圈值(Y)。如果与电机的速度值对应的光圈特征数据中包括目标光圈值(假设Y＝Val _Pos _{N_Speed} ₁)，则将与电机的速度值和目标光圈值对应的预设电机位置(Pos N)确定为目标电机位置。 The preset aperture characteristic data includes only a limited number of preset speed values, preset motor positions, and aperture values. The multiple preset speed values (Speed 0 ... Speed M) include the speed value (Speed X) of the motor. It is assumed that Speed X = Speed 1. Then it is necessary to further determine whether the aperture characteristic data (Val _Pos _{i_Speed} ₁ … Val _Pos _{i_Speed} ₁ , 0 ≦ i ≦ N) corresponding to the speed value of the motor includes the target aperture value (Y). If the aperture characteristic data corresponding to the speed value of the motor includes the target aperture value (assuming Y = Val _Pos _{N_Speed} ₁ ), the preset motor position (Pos N) corresponding to the speed value and the target aperture value of the motor is determined as the target Motor position.

由于预设的光圈特征数据可以反映出预设电机位置、预设速度值与光圈值之间的准确的对应关系，因此，当多个预设速度值包括电机的速度值，且与电机的速度值对应的光圈特征数据中包括目标光圈值时，可以直接根据预设的光圈特征数据确定目标电机位置，提升了目标电机位置的准确性，进而提升了光圈控制的准确性。Because the preset aperture characteristic data can reflect the accurate correspondence between the preset motor position, the preset speed value, and the aperture value, when multiple preset speed values include the speed value of the motor, and the speed of the motor When the target aperture value is included in the aperture characteristic data corresponding to the value, the target motor position can be directly determined based on the preset aperture characteristic data, which improves the accuracy of the target motor position and thus the accuracy of the aperture control.

可选的，本实施例提供的光圈控制方法，还可以包括：Optionally, the aperture control method provided in this embodiment may further include:

若与电机的速度值对应的光圈特征数据中不包括目标光圈值，则根据与电机的速度值对应的光圈特征数据获得电机以电机的速度值运动时电机位置与光圈值之间的对应关系。If the aperture characteristic data corresponding to the speed value of the motor does not include the target aperture value, the correspondence between the motor position and the aperture value when the motor moves at the speed value of the motor is obtained according to the aperture characteristic data corresponding to the speed value of the motor.

根据电机位置与光圈值之间的对应关系，确定目标光圈值对应的目标电机位置。According to the corresponding relationship between the motor position and the aperture value, the target motor position corresponding to the target aperture value is determined.

本实施例提供了一种光圈控制方法，应用于预设的光圈特征数据中包括电机的速度值的场景。若与电机的速度值对应的光圈特征数据中包括目标光圈值，则将与电机的速度值和目标光圈值对应的预设电机位置确定为目标电机位置，提升了确定目标电机位置的准确性，进而提升了光圈控制的准确性。This embodiment provides an aperture control method, which is applied to a scenario in which preset aperture characteristic data includes a speed value of a motor. If the aperture characteristic data corresponding to the speed value of the motor includes the target aperture value, the preset motor position corresponding to the speed value and the target aperture value of the motor is determined as the target motor position, thereby improving the accuracy of determining the target motor position.
