具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
图1是本发明实施例提供的一种变焦方法的步骤流程图，如图1所示，该方法应用于包括多个成像设备的电子设备，包括：FIG. 1 is a flowchart of steps of a zoom method provided by an embodiment of the present invention. As shown in FIG. 1 , the method is applied to an electronic device including multiple imaging devices, including:
步骤101：获取变焦指令。Step 101: Acquire a zoom instruction.
本步骤中，变焦指令中包括用于调节多个成像设备焦距的变焦参数。这里，变焦参数可以为焦距值，即成像设备变焦后对应的焦距值。当然变焦参数也可以为与焦距值相关联的其它参数，该其它参数与焦距值具有固定关系，通过预设计算方式可以根据该其它参数计算得到对应的焦距值。In this step, the zoom instruction includes zoom parameters for adjusting the focal lengths of the multiple imaging devices. Here, the zoom parameter may be a focal length value, that is, a corresponding focal length value after the imaging device is zoomed. Of course, the zoom parameter may also be other parameters associated with the focal length value, the other parameters have a fixed relationship with the focal length value, and the corresponding focal length value can be calculated according to the other parameters through a preset calculation method.
步骤102：根据变焦指令中的变焦参数，调节多个成像设备的焦距。Step 102: Adjust the focal lengths of the multiple imaging devices according to the zoom parameters in the zoom instruction.
本步骤中，同一变焦指令可以调节多个成像设备的焦距。其中，成像设备为依据光线进行成像的设备，可以基于成像设备成像所依据的光线的波长范围对成像设备进行分类。同一类的成像设备将依据相同波长范围的光进行成像；不同类的成像设备将依据不同波长范围的光进行成像。电子设备中的多个成像设备可以为同一类的成像设备，也可以为不同类的成像设备。这里，成像设备可以为相机、手机等。较佳地，可以根据变焦参数调节多个成像设备中至少两个成像设备的焦距。调节成像设备的焦距，即调节成像设备中镜头的焦距，也就是常说的光学变焦。当然调节成像设备的焦距，还可以理解为调节成像设备中与数码变焦相关联的参数，从而达到变焦效果。本发明实施例中，在获取变焦指令之后，可以根据变焦指令中的变焦参数，调节多个成像设备的焦距，实现对多个成像设备的统一变焦，从而减少多个成像设备变焦的操作难度和反应速度，提升后续步骤如多相机跟焦、多相机联动变焦、智能监控、智能追踪的工作效率。In this step, the same zoom instruction can adjust the focal lengths of multiple imaging devices. The imaging device is a device that performs imaging according to light, and the imaging devices can be classified based on the wavelength range of the light on which the imaging device is imaging. Imaging devices of the same type will image based on light in the same wavelength range; imaging devices of different types will image based on light in different wavelength ranges. The multiple imaging devices in the electronic device may be the same type of imaging device, or may be different types of imaging devices. Here, the imaging device may be a camera, a mobile phone, or the like. Preferably, the focal lengths of at least two of the plurality of imaging devices can be adjusted according to the zoom parameter. Adjusting the focal length of the imaging device means adjusting the focal length of the lens in the imaging device, which is often referred to as optical zoom. Of course, adjusting the focal length of the imaging device can also be understood as adjusting the parameters associated with the digital zoom in the imaging device, so as to achieve a zoom effect. In this embodiment of the present invention, after the zoom instruction is acquired, the focal lengths of multiple imaging devices can be adjusted according to the zoom parameters in the zoom instruction, so as to realize unified zooming of the multiple imaging devices, thereby reducing the operational difficulty and difficulty of zooming the multiple imaging devices. The response speed improves the work efficiency of subsequent steps such as multi-camera follow focus, multi-camera linked zoom, intelligent monitoring, and intelligent tracking.
可选地，多个成像设备依据不同波长范围的光进行成像。Optionally, a plurality of imaging devices perform imaging according to light of different wavelength ranges.
这里，光可以依据不同波长范围分为可见光、红外光、紫外光等，而依据不同波长范围的光进行成像的成像设备可以应用于不同的场景中。为适用更多的场景，本发明实施例中的多个成像设备依据不同波长范围的光进行成像。可选地，多个成像设备包括以下至少两种：可见光相机、红外相机、紫 外相机。其中，在多个成像设备包括可见光相机和红外相机时，通过可见光相机和红外相机两者的配合，可以在消防，电力巡检，光伏巡检，安防等行业大大提高作业效率。在多个成像设备包括可见光相机和紫外相机时，在利用紫外相机获取紫外线照射下的影像的同时，利用可见光相机获取高清晰影像，实现同时需要可见光相机和紫外相机进行作业的场景需求。在多个成像设备包括红外相机和紫外相机时，利用红外相机进行红外成像的同时，利用紫外相机获取紫外线照射下的影像，实现同时需要红外相机和紫外相机进行作业的场景需求。当然，多个成像设备也可以理解为包括多个成像模块的同一设备，例如，多个成像设备可以包括可见光相机和红外相机；也可以为一双光相机，其中，双光相机设置有两个成像模块，一个成像模块利用可见光成像，另一个成像模块利用红外光成像。Here, light can be classified into visible light, infrared light, ultraviolet light, etc. according to different wavelength ranges, and imaging devices that perform imaging according to light in different wavelength ranges can be applied to different scenarios. In order to apply to more scenarios, the multiple imaging devices in the embodiments of the present invention perform imaging according to light in different wavelength ranges. Optionally, the plurality of imaging devices include at least two of the following: visible light cameras, infrared cameras, and ultraviolet cameras. Among them, when multiple imaging devices include visible light cameras and infrared cameras, the cooperation of visible light cameras and infrared cameras can greatly improve operational efficiency in fire protection, power inspection, photovoltaic inspection, security and other industries. When multiple imaging devices include a visible light camera and an ultraviolet camera, the visible light camera is used to obtain high-definition images while the ultraviolet camera is used to obtain images under ultraviolet light, so as to achieve the scene requirements that require both the visible light camera and the ultraviolet camera for operation. When multiple imaging devices include an infrared camera and an ultraviolet camera, the infrared camera is used for infrared imaging, and the ultraviolet camera is used to obtain images under ultraviolet radiation, so as to meet the scene requirements that require both the infrared camera and the ultraviolet camera for operation. Of course, multiple imaging devices can also be understood as the same device including multiple imaging modules, for example, the multiple imaging devices can include a visible light camera and an infrared camera; it can also be a dual-light camera, wherein the dual-light camera is provided with two imaging devices Modules, one imaging module uses visible light imaging, and the other imaging module uses infrared light imaging.
可以理解的是，通常可见光相机成像所依据的波长范围，为可见光波长范围内的某一波长范围。也就是说，不同可见光相机成像所依据的波长范围，可以为可见光波长范围内的不同波长范围，本发明实施例中多个成像设备可以为依据同一种光进行成像，但依据不同波长范围的光进行成像的成像设备。例如可见光波长范围为390纳米～780纳米，多个成像设备中的第一成像设备可以为依据390纳米～600纳米的可见光进行成像的可见光相机，第二成像设备可以为依据500纳米～700纳米的可见光进行成像的可见光相机。It can be understood that, the wavelength range on which the visible light camera is usually imaged is a certain wavelength range within the visible light wavelength range. That is to say, the wavelength ranges on which the imaging of different visible light cameras is based may be different wavelength ranges within the visible light wavelength range. An imaging device that performs imaging. For example, the wavelength range of visible light is 390 nanometers to 780 nanometers. The first imaging device in the plurality of imaging devices can be a visible light camera that performs imaging based on visible light of 390 nanometers to 600 nanometers, and the second imaging device can be based on 500 nanometers to 700 nanometers. Visible light camera for imaging with visible light.

Of course, the same screen mode can also be used to display multiple imaging images on the same display screen, and at least some of the images overlap, for example, the imaging centers of the multiple imaging images are placed at the same point on the same display screen; Intuitively comparing the differences between different imaging pictures, and under the condition that the field angles of different imaging pictures are at least partially aligned, it is also possible to quickly locate the position of the same point on different imaging pictures.

本步骤中，变焦控件用于调节多个成像设备中至少两个成像设备的焦距。即，通过变焦控件可以实现对电子设备上的至少两个成像设备进行变焦。这里，变焦控件包括虚拟控件或者实体控件。即可以将电子设备的显示屏中显示的虚拟控件作为变焦控件，如图2所示，为电子设备的显示屏示意图，其中包括显示至少两个成像设备中第一成像设备的成像画面的第一显示区域21、显示至少两个成像设备中第二成像设备的成像画面的第二显示区域22以及变焦控件23，通过对变焦控件23进行输入可以调节第一成像设备和第二成像设备的焦距。当然，变焦控件也可以将电子设备上的实体控件，例如将摇杆、按键、滑动键等作为变焦控件。这里的第一输入可以为点击、滑动、长按、拨动、开启等输入。当然地，第一输入也可以包括预设指令，例如满足特定条件即可触发的输入指令，特定条件包 括特定时间(段)、特定地点、传感器感知到的数据达到阈值等。In this step, the zoom control is used to adjust the focal length of at least two imaging devices in the plurality of imaging devices. That is, zooming of at least two imaging devices on the electronic device can be achieved through the zoom control. Here, the zoom controls include virtual controls or physical controls.
