本申请一些实施例中的一种摄像头角度调整方法，如图8，该方法至少可以应用本申请实施例提供的显示设备上，该方法的执行主体包括但不限于显示设备的控制器，该方法可以包括如下步骤：A camera angle adjustment method in some embodiments of the present application, as shown in FIG. 8 , the method can be applied to at least the display device provided in the embodiments of the present application. The execution subject of the method includes but is not limited to the controller of the display device. Can include the following steps:
S4，响应于接收到指示显示摄像头设置界面的指令，呈现摄像头设置界面，所述摄像头设置界面包括用于调整摄像头初始角度的项目，所述初始角度为所述摄像头启动后所旋转到的目标角度；S4, in response to receiving an instruction to display a camera setting interface, present a camera setting interface, where the camera setting interface includes an item for adjusting the initial angle of the camera, where the initial angle is the target angle to which the camera is rotated after starting ;

S7，响应于接收到保存操作，将摄像头当前所处角度作为初始角度进行保存。S7, in response to receiving the save operation, save the current angle of the camera as the initial angle.
在一些示例性的实现方式中，***设置应用接收用户操作，并调用摄像头控制服务，通过摄像头控制服务执行与用户操作相对应的处理。示例性的，当***设置应用接收到用于调整摄像头角度的操作(如对遥控器上方向按键的按压操作)时，根据用户操作对应的目标调整方向和预设的调整步长，通过Hid1跨进程通信调用摄像头控制服务提供的特定接口(如rotateAroundAxisTo())，控制云台摄像头转动。另一示例性的，在控制云台摄像头转动过程中，***设置应用通过调用摄像头控制服务提供的特定接口(如getRotation())周期性获取摄像头的当前角度，当判定摄像头的当前角度达到相应的极限角度时，关闭摄像头控制服务，以终止云台摄像头转动。In some exemplary implementations, the system setting application receives the user operation, calls the camera control service, and performs processing corresponding to the user operation through the camera control service. Exemplarily, when the system settings application receives an operation for adjusting the angle of the camera (such as a pressing operation on the direction button on the remote control), it adjusts the direction according to the target corresponding to the user operation and the preset adjustment step, and crosses it through Hid1. The process communication calls the specific interface provided by the camera control service (such as rotateAroundAxisTo()) to control the rotation of the PTZ camera. Another example, in the process of controlling the rotation of the PTZ camera, the system setting application periodically obtains the current angle of the camera by calling a specific interface provided by the camera control service (such as getRotation()). When it is determined that the current angle of the camera reaches the corresponding When the angle is at the limit, close the camera control service to stop the pan/tilt camera rotation.
在一些示例性实施方式中，启动设置中“手动调整”应用后，应用调用绑定接口，通过HIDL进程间通信将CameraControlService进行绑定；In some exemplary embodiments, after the "manual adjustment" application in the startup settings, the application calls the binding interface to bind the CameraControlService through HIDL inter-process communication;
绑定成功后，用户可通过遥控器“上、下、左、右”四个方向键通过CameraControlService对摄像头的默认角度进行调节。每按一次按键，摄像头会朝按键方向移动10度。云台摄像头支持水平转动0-120度，垂直转动0-105度；After the binding is successful, the user can adjust the default angle of the camera through CameraControlService through the four direction keys of "up, down, left and right" on the remote control. Each time a button is pressed, the camera moves 10 degrees in the direction of the button. The PTZ camera supports horizontal rotation of 0-120 degrees and vertical rotation of 0-105 degrees;
例如：默认初始角度为：水平60度，垂直90度，此时用户按右键，“手动调整”应用 收到右键的键值后，调用CameraControlService中的rotateAroundAxisTo(Orientation o，int degree)方法进行调整，该方法有两个参数，For example: the default initial angle is: horizontal 60 degrees, vertical 90 degrees, at this time, the user presses the right button, and after the "manual adjustment" application receives the key value of the right button, it calls the rotateAroundAxisTo(Orientation o, int degree) method in CameraControlService to adjust, The method has two parameters,
参数1：Orientation：两个可选参数，Horizontal表示当前是水平转动，Vertical表示垂直转动；Parameter 1: Orientation: Two optional parameters, Horizontal means horizontal rotation, Vertical means vertical rotation;
参数2：degree：表示要转到的绝对角度，即在原来角度加上需要旋转的角度10后得到的角度；Parameter 2: degree: indicates the absolute angle to be turned, that is, the angle obtained after adding the original angle and the angle to be rotated by 10;
因此，用户按右键后，应用将横向参数Horizontal和70度分别传入方法rotateAroundAxisTo中，最终通过调用驱动接口控制摄像头马达转动到水平70度，实现遥控器调整摄像头角度的功能；Therefore, after the user presses the right button, the application passes the horizontal parameters Horizontal and 70 degrees into the method rotateAroundAxisTo respectively, and finally controls the camera motor to rotate to the horizontal 70 degrees by calling the driver interface to realize the function of adjusting the camera angle by the remote control;
在旋转的过程中，“手动调整”应用会通过CameraControlService中的getRotation()接口实时更新记录当前摄像头角度，一旦达到了某一方向上的临界值，会提示用户已转动到云台摄像头边缘，例如，若用户一直按右键，摄像头一直向右转动，转到水平120度时，此时“手动调整”应用获取到旋转后的角度为120度，则弹出提示：摄像头已转到云台边缘。During the rotation process, the "manual adjustment" application will update and record the current camera angle in real time through the getRotation() interface in CameraControlService. Once the critical value in a certain direction is reached, the user will be prompted to rotate to the edge of the PTZ camera, for example, If the user keeps pressing the right button, the camera keeps turning to the right and turns to 120 degrees horizontally. At this time, the "Manual Adjustment" application obtains the rotated angle of 120 degrees, and a prompt will pop up: The camera has turned to the edge of the gimbal.
用户完成调整点击OK键确认，此时“手动调整”应用调用CameraControlService的record()接口记录当前角度，例如：刚才按右键一次，水平角度调整为70度，垂直还是90度，因此会将：水平70度、垂直90度记录下来，后续摄像头默认仰起角度以此为准。After the user completes the adjustment, click the OK button to confirm. At this time, the "Manual Adjustment" application calls the record() interface of CameraControlService to record the current angle. For example, if you pressed the right button once, the horizontal angle is adjusted to 70 degrees, and the vertical angle is still 90 degrees, so it will be: horizontal Record at 70 degrees and 90 degrees vertically, and the default tilt angle of the subsequent cameras shall prevail.
图9中示例性示出了根据一些实施例的调节摄像头的拍摄角度的方法流程图。参见图9，控制器在执行响应于触发摄像头设置选项时产生的摄像头角度调整指令，调节摄像头的拍摄角度，被进一步配置为执行下述步骤：FIG. 9 exemplarily shows a flowchart of a method for adjusting a shooting angle of a camera according to some embodiments.

S33、响应于触发目标调整方式选项时产生的摄像头角度调整指令，调节摄像头的拍摄角度。S33. In response to the camera angle adjustment instruction generated when the target adjustment mode option is triggered, adjust the shooting angle of the camera.
用户通过控制装置中的选择按键，例如方向控制按键中的“确认键”，触发摄像头设置入口界面中的摄像头角度调整选项时，会产生选择指令，以表征当前与显示设备交互的结果为调整摄像头拍摄角度。When the user triggers the camera angle adjustment option in the camera setting portal interface through the selection button in the control device, such as the "confirm button" in the direction control button, a selection instruction will be generated to indicate that the current interaction with the display device is the result of adjusting the camera. Filming angle.

Schematic diagram of the interactive interface. 10 and FIG. 11 , the controller is further configured to perform the following steps when executing the camera angle adjustment instruction generated when the target adjustment mode option is triggered in step S33 to adjust the shooting angle of the camera:
S3311、响应于触发手动调整方式选项时产生的摄像头角度调整指令，开启摄像头以及在显示器中呈现摄像头采集的预览画面，预览画面中包括操作引导提示页面和展示方向控制按键的方向操作虚拟按键。S3311. In response to the camera angle adjustment instruction generated when the manual adjustment mode option is triggered, turn on the camera and present a preview screen captured by the camera on the display, where the preview screen includes an operation guide prompt page and a virtual button for displaying the direction of the direction control button.
S3312、响应于触发控制装置中的方向控制按键产生的控制指令，控制摄像头跟随控制指令指示的方向进行转动，将摄像头的拍摄角度调整到用户所需视角。S3312 , in response to the control instruction generated by triggering the direction control button in the control device, control the camera to rotate in the direction indicated by the control instruction, and adjust the shooting angle of the camera to the viewing angle required by the user.
用户在选择手动调整方式选项时，产生对应的摄像头角度调整指令，此时，控制器执行摄像头角度调整指令，控制摄像头开启。摄像头开启后，即进行预览画面的采集，同步将采集到的用户图像显示在显示器中。此时，显示器中的用户界面由显示的摄像头角度调整选项页面切换显示为摄像头采集到的预览画面。When the user selects the manual adjustment mode option, a corresponding camera angle adjustment instruction is generated. At this time, the controller executes the camera angle adjustment instruction to control the camera to be turned on. After the camera is turned on, the preview image is collected, and the collected user image is displayed on the display synchronously. At this time, the user interface in the display is switched from the displayed camera angle adjustment option page to the preview image captured by the camera.
为便于用户能够快速并简便的对摄像头角度进行手动调整，需要在预览画面中同步显示操作引导提示页面和展示方向控制按键的方向操作虚拟按键。方向操作虚拟按键用于标识用户在触发方向控制按键时的触发状态，操作引导提示页面用于提示手动调整摄像头角度时的相关操作。其中，操作引导提示页面包括操作步骤提示页面和设置提示页面，操作步骤提示页面用于显示手动调整摄像头角度时的操作步骤，设置提示页面用于显示在完成摄像头角度调整后的相关设置。In order to facilitate the user to quickly and easily adjust the angle of the camera manually, it is necessary to simultaneously display the operation guidance prompt page and the directional operation virtual keys of the directional control keys in the preview screen. The direction operation virtual button is used to identify the trigger state when the user triggers the direction control button, and the operation guide prompt page is used to prompt the relevant operation when manually adjusting the camera angle. The operation guide prompt page includes an operation step prompt page and a setting prompt page. The operation step prompt page is used to display the operation steps when manually adjusting the camera angle, and the setting prompt page is used to display the relevant settings after completing the camera angle adjustment.
在一些实施例中，方向操作虚拟按键显示在预览画面的顶端中部位置；操作引导提示页面显示在预览画面的右侧位置，其中，操作步骤提示页面位于右侧上端位置，设置提示页面位于右侧下端位置；预览画面的其他位置显示摄像头采集的用户图像。In some embodiments, the directional operation virtual key is displayed at the top middle position of the preview screen; the operation guidance prompt page is displayed on the right side of the preview screen, wherein the operation step prompt page is located at the upper end of the right side, and the setting prompt page is located on the right side Bottom position; other positions of the preview screen display the user image captured by the camera.
由于控制装置的按键值与摄像头角度已建立绑定关系，在用户触发控制装置中的方向控制按键时，随即摄像头角度产生相应的调整，例如，用户触发方向控制按键的 “左键”，则控制摄像头向左转动；用户触发方向控制按键的“右键”，则控制摄像头向右转动；用户触发方向控制按键的“上键”，则控制摄像头向上转动；用户触发方向控制按键的“下键”，则控制摄像头向下转动。Since the key value of the control device and the camera angle have established a binding relationship, when the user triggers the direction control button in the control device, the camera angle is adjusted accordingly. The camera rotates to the left; the user triggers the "right button" of the direction control button to control the camera to rotate to the right; the user triggers the "up button" of the direction control button to control the camera to rotate upward; the user triggers the "down button" of the direction control button ”, then control the camera to rotate downward.
可见，用户在触发控制装置中的方向控制按键时产生的控制指令中携带摄像头的转动方向，控制器响应控制指令，即可控制摄像头跟随控制指令指示的方向进行转动，将摄像头的拍摄角度调整到用户所需视角。另外，基于操作引导提示可使得用户能够较为直观的对摄像头视角调节，操作简便，交互引导性友好，在能够便捷地调整摄像头角度的同时，通过交互能够有效提升用户体验水平。It can be seen that the user carries the rotation direction of the camera in the control command generated when triggering the direction control button in the control device, and the controller responds to the control command to control the camera to rotate in the direction indicated by the control command, and adjust the shooting angle of the camera to User's desired perspective. In addition, based on the operation guidance prompts, users can intuitively adjust the camera angle of view, the operation is simple, and the interaction guidance is friendly. While the camera angle can be adjusted conveniently, the user experience level can be effectively improved through interaction.
为便于快速调整摄像头的拍摄角度，用户通过触发方向控制按键时，可产生不同角度的转动，为此，可设定为短按按键或长按按键对摄像头角度进行小角度转动或大角度转动。In order to quickly adjust the shooting angle of the camera, when the user triggers the direction control button, different angles of rotation can be generated. To this end, it can be set to short-press the button or long-press the button to rotate the camera at a small angle or a large angle.
在一些实施例中，控制器在执行步骤S3312中的响应于触发控制装置中的方向控制按键产生的控制指令，控制摄像头跟随所述控制指令指示的方向进行转动，被进一步配置为执行下述步骤：In some embodiments, the controller is further configured to perform the following steps when executing the control instruction generated in step S3312 in response to triggering the direction control button in the control device to control the camera to rotate in the direction indicated by the control instruction. :
步骤33121、接收触发控制装置中的方向控制按键产生的控制指令。Step 33121: Receive a control instruction generated by triggering a direction control button in the control device.
步骤33122、判断控制指令是短按调节控制指令还是长按调节控制指令。Step 33122: Determine whether the control instruction is a short-press adjustment control instruction or a long-press adjustment control instruction.
步骤33123、如果控制指令是短按调节控制指令，则按照第一控制角度，控制摄像头跟随短按调节控制指令指示的方向进行转动。Step 33123: If the control instruction is a short-press adjustment control instruction, control the camera to rotate in the direction indicated by the short-press adjustment control instruction according to the first control angle.
步骤33124、如果控制指令是长按调节控制指令，则按照第二控制角度，控制摄像头跟随长按调节控制指令指示的方向进行转动，第二控制角度大于第一控制角度。Step 33124: If the control instruction is a long press adjustment control instruction, control the camera to rotate in the direction indicated by the long press adjustment control instruction according to the second control angle, and the second control angle is greater than the first control angle.
用户每点击方向控制按键中的任一个按键，即产生对应的控制指令。控制器接收到控制指令后，根据该按键的触发时长，判断该控制指令为短按调节控制指令还是长按调节控制指令。如果触发时长小于或等于预设时长，则判断控制指令为短按调节控制指令；如果触发时长大于预设时长，则判断控制指令为长按调节控制指令。其中，预设时长可设定为2s，也可为其他数值，可根据实际情况而定。Each time the user clicks any one of the directional control buttons, a corresponding control instruction is generated. After receiving the control command, the controller determines whether the control command is a short-press adjustment control command or a long-press adjustment control command according to the triggering duration of the button. If the trigger duration is less than or equal to the preset duration, the control command is determined to be a short-press adjustment control command; if the trigger duration is greater than the preset duration, the control command is determined to be a long-press adjustment control command. The preset duration may be set to 2s, or may be other values, which may be determined according to the actual situation.
在控制指令是短按调节控制指令时，则按照第一控制角度控制摄像头跟随短按调节控制指令指示的方向进行转动。在一些实施例中，第一控制角度可设定为10度。在用户需要小范围的调整摄像头角度时，可短按方向控制按键中的某个按键，使得摄像头角度以10°/次的调整频率进行调整。When the control instruction is a short-pressing adjustment control instruction, the camera is controlled to rotate in the direction indicated by the short-pressing adjustment control instruction according to the first control angle. In some embodiments, the first control angle may be set to 10 degrees. When the user needs to adjust the camera angle in a small range, he can short press a button in the direction control buttons, so that the camera angle can be adjusted at an adjustment frequency of 10°/time.
例如，如果用户短按方向控制按键中的“左键”，则控制摄像头向左转动10°，改变摄像头的拍摄角度；如果用户短按方向控制按键中的“右键”，则控制摄像头向右转动10°，改变摄像头的拍摄角度；如果用户短按方向控制按键中的“上键”，则控制摄像头向上转动10°，改变摄像头的拍摄角度；如果用户短按方向控制按键中的“下键”，则控制摄像头向下转动10°，改变摄像头的拍摄角度。For example, if the user short presses the "left button" in the direction control button, the camera is controlled to rotate 10° to the left to change the shooting angle of the camera; if the user short presses the "right button" in the direction control button, the camera is controlled to the right Rotate 10° to change the shooting angle of the camera; if the user briefly presses the "up button" in the key”, then control the camera to rotate 10° downward to change the shooting angle of the camera.
在控制指令是长按调节控制指令时，则按照第二控制角度控制摄像头跟随长按调节控制指令指示的方向进行转动。在一些实施例中，第二控制角度大于第一控制角度，第二控制角度可设定为30度。在用户需要大范围的调整摄像头角度时，可长按方向控制按键中的某个按键，使得摄像头角度以30°/次的调整频率进行调整，提高角度调整效率。When the control instruction is a long-press adjustment control instruction, the camera is controlled to rotate in the direction indicated by the long-press adjustment control instruction according to the second control angle. In some embodiments, the second control angle is greater than the first control angle, and the second control angle may be set to 30 degrees. When the user needs to adjust the camera angle in a wide range, he can long press a button in the direction control buttons, so that the camera angle can be adjusted at a frequency of 30°/time, which improves the angle adjustment efficiency.
例如，如果用户长按方向控制按键中的“左键”，则控制摄像头向左转动30°， 改变摄像头的拍摄角度；如果用户长按方向控制按键中的“右键”，则控制摄像头向右转动30°，改变摄像头的拍摄角度；如果用户长按方向控制按键中的“上键”，则控制摄像头向上转动30°，改变摄像头的拍摄角度；如果用户长按方向控制按键中的“下键”，则控制摄像头向下转动30°，改变摄像头的拍摄角度。For example, if the user long presses the "left button" in the direction control button, the camera is controlled to rotate 30° to the left to change the shooting angle of the camera; if the user long presses the "right button" in the direction control button, the camera is controlled to the right Rotate 30° to change the shooting angle of the camera; if the user long presses the "up button" in the key", then control the camera to rotate down 30° to change the camera's shooting angle.
摄像头的拍摄角度被调整后，摄像头实时采集的预览画面也发生变化，预览画面中呈现的用户图像为摄像头按照新拍摄角度采集的新用户图像，并根据新用户图像生成新预览画面同步显示在显示器中，此时，显示器中展示的预览画面实时根据摄像头调整拍摄角度的变化产生相应变化。After the shooting angle of the camera is adjusted, the preview image captured by the camera in real time also changes. The user image displayed in the preview image is the new user image collected by the camera according to the new shooting angle, and a new preview image is generated based on the new user image and displayed on the monitor synchronously. , at this time, the preview image displayed on the display changes in real time according to the change of the camera's adjustment of the shooting angle.
可见，本实施例提供的显示设备，在用户触发控制装置中的方向控制按键时，即可实现对摄像头角度的调整。且不同触发时长也可产生对应的不同角度调整阈值，便于用户能够快速并准确地将摄像头角度调整到使用最佳角度。It can be seen that, with the display device provided in this embodiment, when the user triggers the direction control button in the control device, the angle of the camera can be adjusted. In addition, different trigger durations can also generate corresponding different angle adjustment thresholds, so that the user can quickly and accurately adjust the camera angle to the optimum angle for use.
为了便于用户能够实时查看到显示设备是否响应用户触发控制装置的方向控制按键时的控制指令，控制器在执行响应于触发控制装置中的方向控制按键产生的控制指令之后，被进一步配置为：接收触发方向控制按键中目标按键产生的目标控制指令；响应于目标控制指令，在方向操作虚拟按键中与目标按键对应的目标虚拟按键上呈现闪烁状态。In order for the user to be able to check in real time whether the display device responds to the control instruction when the user triggers the direction control button of the control device, after the controller executes the control instruction generated in response to triggering the direction control button in the control device, the controller is further configured to: receive The target control instruction generated by the target button in the direction control buttons is triggered; in response to the target control instruction, the target virtual button corresponding to the target button in the direction operation virtual button presents a flashing state.
用户每触发一次方向控制按键中的某个按键时，即可产生相应的目标控制指令，控制器接收到目标控制指令后，即可改变方向操作虚拟按键中与目标按键对应的目标虚拟按键上的显示状态，例如，可使目标虚拟按键闪烁一次。而闪烁状态可通过改变目标虚拟按键的亮度或显示颜色来实现。Each time the user triggers a certain button in the direction control buttons, the corresponding target control command can be generated. After the controller receives the target control command, it can change the direction to operate the virtual buttons on the target virtual button corresponding to the target button. Displaying the status, for example, can cause the target virtual key to blink once. The blinking state can be achieved by changing the brightness or display color of the target virtual key.
在一些实施例中，如果用户短按方向控制按键中的目标按键，则对应的目标虚拟按键短暂闪烁一次，可不超过2秒；如果用户长按方向控制按键中的目标按键，则对应的目标虚拟按键持续闪烁一次，持续时长可超过2秒，如3秒、4秒，具体的持续时长可与用户长按目标按键的触发时长相同。In some embodiments, if the user briefly presses the target button in the direction control buttons, the corresponding target virtual button flashes once briefly, which may not exceed 2 seconds; if the user presses the target button in the direction control buttons for a long time, the corresponding target virtual button The button flashes continuously once, and the duration can exceed 2 seconds, such as 3 seconds or 4 seconds, and the specific duration can be the same as the triggering duration of the user long-pressing the target button.
例如，用户触发方向控制按键中的“左键”，则显示器中显示的方向操作虚拟按键中的“左键”闪烁一次；用户触发方向控制按键中的“右键”，则显示器中显示的方向操作虚拟按键中的“右键”闪烁一次；用户触发方向控制按键中的“上键”，则显示器中显示的方向操作虚拟按键中的“上键”闪烁一次；用户触发方向控制按键中的“下键”，则显示器中显示的方向操作虚拟按键中的“下键”闪烁一次。For example, if the user triggers the "left button" in the direction control button, the "left button" in the directional operation virtual button displayed in the display flashes once; the user triggers the "right button" in the direction control button, the direction operation displayed in the display The "right key" in the virtual key flashes once; the user triggers the "up key" in the direction control key, and the "up key" in the virtual key for the direction operation displayed in the display flashes once; the user triggers the "down key" in the direction control key ”, the “Down key” in the virtual keys for direction operation displayed in the display flashes once.
用户在通过前述实施例提供的方式对摄像头的拍摄角度完成调整后，可对调整后的摄像头角度进行存储，此时，摄像头可按照新拍摄角度采集用户图像，以使得用户能够以最佳使用角度与显示设备进行交互。After the user has adjusted the shooting angle of the camera in the manner provided by the foregoing embodiment, the adjusted camera angle can be stored. At this time, the camera can collect the user's image according to the new shooting angle, so that the user can use the best angle. Interact with the display device.
为此，图12中示例性示出了根据一些实施例的保存调整后摄像头拍摄角度的交互界面示意图。参见图12，在一些实施例中，在完成摄像头角度调整后，控制器被进一步配置为执行下述步骤：响应于触发方向控制按键时产生的角度控制完毕指令，存储调整拍摄角度后的摄像头角度，以及，在预览画面中呈现保存完毕提示，保存完毕提示用于提示已完成调整拍摄角度后的摄像头角度的存储。To this end, FIG. 12 exemplarily shows a schematic diagram of an interactive interface for saving and adjusting the shooting angle of the camera according to some embodiments. Referring to FIG. 12 , in some embodiments, after completing the camera angle adjustment, the controller is further configured to perform the following steps: in response to the angle control completion instruction generated when the direction control button is triggered, store the camera angle after adjusting the shooting angle , and a saving completion prompt is displayed on the preview screen, and the saving completion prompt is used to prompt that the camera angle storage after adjusting the shooting angle has been completed.
由于显示器中的预览画面中实时显示操作引导提示页面，具体地，在预览画面的右侧下端位置实时显示设置提示页面，以提示用户可在完成摄像头角度调整后的相关设置。Because the operation guide prompt page is displayed in real time in the preview screen on the display, specifically, the setting prompt page is displayed in real time at the lower right end of the preview screen to prompt the user for relevant settings after completing the camera angle adjustment.
在一些实施例中，设置提示页面中显示的内容可为“按确认键-保存”，用户根据设置提示页面中的内容，触发控制装置中的方向控制按键的“确认键”，随即产生角度控制完毕指令，控制器响应该指令，实现对当前完成摄像头拍摄角度调整后的新摄像头角度的存储。In some embodiments, the content displayed in the setting prompt page may be “press the confirmation key-save”, and the user triggers the “confirmation key” of the direction control key in the control device according to the content in the setting prompt page, and the angle control key is generated immediately After completing the instruction, the controller responds to the instruction, and realizes the storage of the new camera angle after the current adjustment of the camera shooting angle is completed.
同时，为便于告知用户是否完成新摄像头角度的存储，在控制器响应“确认键”产生的角度控制完毕指令，对新摄像头角度完成存储后，随即生成保存完毕提示，并显示在预览画面中。用户在查看到预览画面中显示的保存完毕提示后，即可确定控制器已完成调整拍摄角度后的摄像头角度的存储。保存完毕提示可为图12所示的“摄像头角度已保存”。At the same time, in order to inform the user whether the storage of the new camera angle is completed, the controller responds to the "OK button" to generate the angle control completion command, and after the storage of the new camera angle is completed, a save completion prompt will be generated and displayed on the preview screen. After viewing the saving completion prompt displayed in the preview screen, the user can determine that the controller has completed the storage of the camera angle after adjusting the shooting angle. After saving, the prompt can be "Camera angle has been saved" as shown in Figure 12.
由于用户通过控制装置实现对摄像头角度的调整时，可能会出现调整的角度均不满意想要重新调整，或者，完成摄像头的当前次使用，需要控制摄像头的拍摄角度恢复至初始状态时，本发明实施例提供的显示设备，可对摄像头的拍摄角度进行重置。When the user adjusts the angle of the camera through the control device, there may be cases where the adjusted angle is not satisfied and wants to readjust, or when the current use of the camera is completed and the shooting angle of the camera needs to be controlled to return to the initial state, the present invention The display device provided by the embodiment can reset the shooting angle of the camera.
图13中示例性示出了根据一些实施例的重置摄像头拍摄角度的交互界面示意图。参见图13，在一些实施例中，在对摄像头的拍摄角度进行重置时，控制器被进一步配置为执行下述步骤：响应于触发控制装置中菜单键时产生的重置指令，在预览画面中呈现重置提示，重置提示用于提示摄像头的拍摄角度已恢复调整前的初始角度值。FIG. 13 exemplarily shows a schematic diagram of an interactive interface for resetting a camera shooting angle according to some embodiments. Referring to FIG. 13 , in some embodiments, when resetting the shooting angle of the camera, the controller is further configured to perform the following steps: in response to the reset instruction generated when the menu key in the control device is triggered, in the preview screen The reset prompt is displayed in the reset prompt, which is used to prompt that the shooting angle of the camera has returned to the initial angle value before adjustment.
为便于用户对摄像头拍摄角度进行重置，可在控制装置上设置菜单键，在选择按键为菜单键时，用户触发菜单键，即可实现对摄像头拍摄角度的重置。In order to facilitate the user to reset the shooting angle of the camera, a menu key can be set on the control device. When the selection key is the menu key, the user can trigger the menu key to reset the shooting angle of the camera.
在一些实施例中，设置提示页面中显示的内容可为“按菜单键-重置”，用户根据设置提示页面中的内容，触发控制装置中的菜单键，随即产生重置指令，使得摄像头的拍摄角度恢复至初始状态，初始状态是指开启摄像头时摄像头的所处角度。In some embodiments, the content displayed in the setting prompt page may be "press menu key-reset", the user triggers the menu key in the control device according to the content in the setting prompt page, and then generates a reset instruction, so that the camera's The shooting angle returns to the initial state, which refers to the angle of the camera when the camera is turned on.
同时，为便于告知用户是否完成摄像头角度的重置，在控制器响应菜单键产生的重置指令，对摄像头角度恢复至初始状态后，随即生成重置提示，并显示在预览画面中。用户在查看到预览画面中显示的重置提示后，即可确定控制器已完成摄像头角度的重置。重置提示可为图13所示的“摄像头角度已重置”。At the same time, in order to easily inform the user whether the reset of the camera angle is completed, after the controller responds to the reset command generated by the menu key and restores the camera angle to the initial state, a reset prompt is generated and displayed on the preview screen. After viewing the reset prompt displayed in the preview screen, the user can determine that the controller has completed the reset of the camera angle. The reset prompt can be "Camera angle has been reset" as shown in Figure 13.
如果用户一直朝一个方向调整摄像头的角度，如用户始终触发方向控制按键中的左键，使得摄像头一直向左转动，那么将会出现摄像头转动到左侧边缘的情况，此时，摄像头无法再向左转动。If the user keeps adjusting the angle of the camera in one direction, for example, if the user always triggers the left button in the direction control button, so that the camera keeps turning to the left, the camera will rotate to the left edge, at this time, the camera can no longer Turn left.
图14中示例性示出了根据一些实施例的摄像头拍摄角度转动超出界限的交互界面示意图。参见图14，在一些实施例中，为便于用户能够改变角度的转动方向，控制器被进一步配置为执行下述步骤：在摄像头的拍摄角度达到预设角度范围的阈值时，在预览画面中呈现转动超出界限提示，转动超出界限提示用于提示摄像头已转动到最大角度值。FIG. 14 exemplarily shows a schematic diagram of an interactive interface in which the rotation of the camera shooting angle exceeds the limit according to some embodiments. Referring to FIG. 14 , in some embodiments, in order to facilitate the user to change the rotation direction of the angle, the controller is further configured to perform the following steps: when the shooting angle of the camera reaches the threshold value of the preset angle range, display the image in the preview screen Rotation exceeds the limit prompt, the rotation beyond the limit prompt is used to indicate that the camera has been rotated to the maximum angle value.
如果调整后的摄像头的拍摄角度达到预设角度范围的阈值时，说明摄像头已转动到某一侧的边缘，无法再向该侧转动，需要提示用户。此时，生成转动超出界面提示并显示在预览画面中，以提示用户摄像头已转动到最大角度值。转动超出界限提示可为图14中所示的“摄像头已经转动到云台边缘”。If the adjusted shooting angle of the camera reaches the threshold of the preset angle range, it means that the camera has been rotated to the edge of a certain side and cannot be rotated to that side any more, and the user needs to be prompted. At this time, a rotation exceeding interface prompt is generated and displayed on the preview screen to prompt the user that the camera has rotated to the maximum angle value. If the rotation exceeds the limit, the prompt can be "The camera has been rotated to the edge of the gimbal" as shown in Figure 14.
前述实施例提供的显示设备，提供用户手动调整摄像头角度的实现方式，即通过触发控制装置中的方向控制按键实现摄像头角度的调整。而在其他实施例中，显示设备还可提供智能调整摄像头角度的实现方式。The display device provided in the foregoing embodiments provides an implementation manner for the user to manually adjust the angle of the camera, that is, to adjust the angle of the camera by triggering the direction control button in the control device. In other embodiments, the display device may further provide an implementation manner of intelligently adjusting the angle of the camera.
在一些实施例中，如果用户想要采用智能调整摄像头角度的方式时，可在摄像头角度调整选项页面中选定智能调整方式选项，即用户选择的目标调整方式选项为智能调整方式选项时。In some embodiments, if the user wants to use the intelligent adjustment method of the camera angle, the intelligent adjustment method option can be selected in the camera angle adjustment option page, that is, when the target adjustment method option selected by the user is the intelligent adjustment method option.
图15中示例性示出了根据一些实施例的基于智能调整方式调节摄像头的拍摄角度的方法流程图；图16中示例性示出了根据一些实施例的基于智能调整方式调节摄像头的拍摄角度的交互界面示意图。参见图15和图16，控制器在执行步骤S33中的响应于触发目标调整方式选项时产生的摄像头角度调整指令，调节所述摄像头的拍摄角度，被进一步配置为执行下述步骤：FIG. 15 exemplarily shows a flowchart of a method for adjusting the shooting angle of a camera based on an intelligent adjustment method according to some embodiments; FIG. 16 exemplarily shows a method of adjusting the shooting angle of a camera based on an intelligent adjustment method according to some embodiments. Schematic diagram of the interactive interface. 15 and FIG. 16 , the controller is further configured to perform the following steps when executing the camera angle adjustment instruction generated when the target adjustment mode option is triggered in step S33 to adjust the shooting angle of the camera:
S3321、响应于触发智能调整方式选项时产生的摄像头角度调整指令，开启摄像头以及在显示器中呈现摄像头采集的预览画面，预览画面中包括用户交互行为引导页面、操作引导提示页面和用户图像。S3321. In response to the camera angle adjustment instruction generated when the smart adjustment mode option is triggered, turn on the camera and present a preview image captured by the camera on the display, where the preview image includes a user interaction behavior guide page, an operation guide prompt page, and a user image.
S3322、响应于用户在面对显示器的方向移动时产生的控制指令，控制摄像头跟随控制指令指示的方向进行转动，将摄像头的拍摄角度调整到用户所需视角。S3322. In response to the control instruction generated by the user moving in the direction facing the display, control the camera to rotate in the direction indicated by the control instruction, and adjust the shooting angle of the camera to the viewing angle required by the user.
用户在选择智能调整方式选项时，产生对应的摄像头角度调整指令，此时，控制器执行摄像头角度调整指令，控制摄像头开启。摄像头开启后，即进行预览画面的采集，同步将采集到的用户图像显示在显示器中。此时，显示器中的用户界面由显示的摄像头角度调整选项页面切换显示为摄像头采集到的预览画面。When the user selects the intelligent adjustment mode option, a corresponding camera angle adjustment instruction is generated. At this time, the controller executes the camera angle adjustment instruction to control the camera to be turned on. After the camera is turned on, the preview image is collected, and the collected user image is displayed on the display synchronously. At this time, the user interface in the display is switched from the displayed camera angle adjustment option page to the preview image captured by the camera.
为便于用户能够快速并简便的对摄像头角度进行智能调整，需要在预览画面中同步显示用户交互行为引导页面、操作引导提示页面和用户图像。用户交互行为引导页面用户展示用户与显示设备交互以调整摄像头角度的交互方式，操作引导提示页面用于提示手动调整摄像头角度时的相关操作，用户图像用于体现用户的移动方向和移动距离程度。In order to facilitate the user to quickly and easily adjust the angle of the camera intelligently, it is necessary to simultaneously display the user interaction behavior guidance page, the operation guidance prompt page and the user image in the preview screen. The user interaction behavior guide page shows the user how the user interacts with the display device to adjust the camera angle. The operation guide prompt page is used to prompt the relevant operations when manually adjusting the camera angle. The user image is used to reflect the user's moving direction and moving distance.
在一些实施例中，用户交互行为引导页面显示在预览画面的右侧位置，操作引导提示页面显示在预览画面的上侧位置，用户图像显示在预览画面的中间位置。In some embodiments, the user interaction behavior guide page is displayed on the right side of the preview screen, the operation guide prompt page is displayed on the upper side of the preview screen, and the user image is displayed in the middle position of the preview screen.
如果在此刻之前摄像头角度并未进行调整过，则在预览画面的上部位置显示角度调整状态提示，显示内容可为如图16中所示的“智能摄像头角度调整”。操作引导提示页面位于角度调整状态提示的下方，显示内容可为图16中所示的“请移动到一个合适位置，摄像头将会智能跟踪，并调节至最优角度”。用户交互行为引导页面的显示内容可为图16中所示的“比手势”，例如，“OK手势”可执行保存操作，“手指手势”可执行退出操作。If the camera angle has not been adjusted before this moment, an angle adjustment status prompt will be displayed in the upper position of the preview screen, and the displayed content may be "smart camera angle adjustment" as shown in Figure 16. The operation guide prompt page is located below the angle adjustment state prompt, and the displayed content can be as shown in Figure 16, "Please move to a suitable position, the camera will intelligently track and adjust to the optimal angle". The displayed content of the user interaction behavior guidance page may be the "comparison gesture" shown in FIG. 16 , for example, the "OK gesture" can perform the save operation, and the "finger gesture" can perform the exit operation.
用户图像显示在预览画面的其他位置，并在用户图像的周围显示箭头以指示用户的可移动方向。例如，如果用户图像中所示用户呈站立姿势，则在用户图像的周围显示左箭头、右箭头和下箭头，以指示用户可向左移动位置、向右移动位置或向下移动位置(改站立姿势为蹲坐姿势)；如果用户图像中所示用户呈蹲坐姿势，则在用户图像的周围显示左箭头、右箭头、下箭头和上箭头，以指示用户可向左移动位置、向右移动位置、向下移动位置(改蹲坐姿势为坐姿势)，或向上移动位置(改蹲坐姿势为站立姿势)。The user image is displayed elsewhere on the preview screen, and arrows are displayed around the user image to indicate the direction in which the user can move. For example, if the user is shown in a standing position, a left arrow, right arrow, and down arrow are displayed around the user image to indicate that the user can move the position to the left, move the position right, or move the position down (instead of standing Squat pose); if the user is shown in a squat pose, a left arrow, right arrow, down arrow, and up arrow are displayed around the user image to indicate that the user can move the position left, move right position, move the position down (change the squat position to the sitting position), or move the position up (change the squat position to the standing position).
将摄像头实时采集到的用户图像的移动方向与摄像头角度建立绑定关系，在用户向某个方向移动位置时，可同步控制摄像头产生相应角度调整，例如，以用户面对显示器的所处方向，如果用户向左移动，则控制摄像头向左移动；如果用户向右移动， 则控制摄像头向右移动；如果用户向下移动，则控制摄像头向下移动；如果用户向上移动，则控制摄像头向上移动。A binding relationship is established between the moving direction of the user image captured by the camera in real time and the camera angle. When the user moves the position in a certain direction, the camera can be synchronously controlled to adjust the corresponding angle. For example, according to the direction where the user faces the display, If the user moves left, control the camera to move left; if the user moves right, control the camera to move right; if the user moves down, control the camera to move down; if the user moves up, control the camera to move up.
可见，用户在摄像头的拍摄区域内移动位置时，随即产生携带摄像头转动方向的控制指令，控制器响应该控制指令，即可控制摄像头跟随控制指令指示的方向进行转动，将摄像头的拍摄角度调整到用户所需视角。It can be seen that when the user moves the position in the shooting area of the camera, a control command carrying the rotation direction of the camera is generated immediately, and the controller responds to the control command to control the camera to rotate in the direction indicated by the control command, and adjust the shooting angle of the camera to User's desired perspective.
本发明实施例提供的显示设备，实现智能调整摄像头拍摄角度，根据用户在摄像头的拍摄区域内的移动位置，由控制器对用户改变的位置进行分析，判断出用户改变位置的方向，进而作为摄像头调整角度的转动方向，实现对摄像头拍摄角度的智能调整，无需用户过多的操作，操作简便，交互引导性好，以快速地调整摄像头角度，有效提升用户体验水平。The display device provided by the embodiment of the present invention realizes intelligent adjustment of the shooting angle of the camera. According to the moving position of the user in the shooting area of the camera, the controller analyzes the position changed by the user, determines the direction in which the user changes the position, and then acts as the camera. Adjust the rotation direction of the angle to realize the intelligent adjustment of the camera shooting angle, without the need for excessive user operations, easy operation, and good interaction guidance, so as to quickly adjust the camera angle and effectively improve the user experience level.
若用户完成对摄像头角度的调整后，预览画面中呈现的用户交互行为引导页面中显示有保存操作的交互手势，用户跟随用户交互行为引导页面的指示作出第一手势，例如作出“OK手势”时，产生角度控制完毕指令，控制器响应该指令，实现对当前完成摄像头拍摄角度调整后的新摄像头角度的存储。If the user completes the adjustment of the camera angle, the user interaction behavior guidance page displayed in the preview screen displays the interaction gesture of the save operation, and the user follows the instructions of the user interaction behavior guidance page to make the first gesture, for example, when making an "OK gesture" , an angle control completion command is generated, and the controller responds to the command to store the new camera angle after the current camera shooting angle adjustment is completed.
在一些实施例中，为便于告知用户是否完成新摄像头角度的存储，在控制器响应“第一手势”产生的角度控制完毕指令，对新摄像头角度完成存储后，随即生成保存完毕提示，并显示在预览画面中。用户在查看到预览画面中显示的保存完毕提示后，即可确定控制器已完成调整拍摄角度后的摄像头角度的存储。In some embodiments, in order to inform the user whether the storage of the new camera angle is completed, after the controller completes the storage of the new camera angle in response to the angle control completion instruction generated by the "first gesture", a saving completion prompt is generated immediately and displayed. in the preview screen. After viewing the saving completion prompt displayed in the preview screen, the user can determine that the controller has completed the storage of the camera angle after adjusting the shooting angle.
若用户想要采用调整后的新摄像头角度进行图像采集，则可退出当前智能摄像头角度调整页面，此时，用户跟随用户交互行为引导页面的指示作出第二手势，例如作出“手掌手势”时，产生退出指令，控制器响应退出指令，退出智能摄像头角度调整的操作，即在预览画面中取消用户交互行为引导页面和操作引导提示页面的显示，此时显示器中显示的仅为摄像头根据新摄像头角度采集的用户图像。If the user wants to use the adjusted new camera angle for image capture, he can exit the current smart camera angle adjustment page. At this time, the user follows the instructions on the user interaction behavior guidance page to make a second gesture, such as when making a "palm gesture" , generate an exit instruction, the controller responds to the exit instruction and exits the operation of adjusting the angle of the smart camera, that is, cancels the display of the user interaction behavior guidance page and the operation guidance prompt page in the preview screen, and the display shows only the camera according to the new camera. User image captured at an angle.
在完成摄像头角度调整并保存新角度完毕后，则在预览画面的上部位置显示的角度调整状态提示进行改变，并改变用户交互行为引导页面的显示内容和操作引导提示页面的显示内容，以告知用户已完成摄像头角度的调整。After completing the camera angle adjustment and saving the new angle, the angle adjustment status prompt displayed in the upper position of the preview screen is changed, and the display content of the user interaction behavior guidance page and the display content of the operation guidance prompt page are changed to inform the user. The adjustment of the camera angle has been completed.
图17中示例性示出了根据一些实施例的基于智能调整方式完成调节摄像头的拍摄角度的交互界面示意图。参见图17，改变后的角度调整状态提示的显示内容可为“摄像头角度已保存”；改变后的操作引导提示页面的显示内容可为“调整摄像头角度需要先比手势重置”；改变后的用户交互行为引导页面的显示内容由原显示保存手势的位置替换显示为重置手势，例如，比“拳头手势”可执行重置操作。FIG. 17 exemplarily shows a schematic diagram of an interactive interface for adjusting the shooting angle of a camera based on an intelligent adjustment method according to some embodiments. Referring to Fig. 17, the displayed content of the changed angle adjustment status prompt can be "Camera angle has been saved"; the displayed content of the changed operation guidance prompt page can be "To adjust the camera angle needs to be reset before gestures"; The displayed content of the user interaction behavior guidance page is replaced by a reset gesture from the location where the save gesture was originally displayed. For example, a reset operation can be performed more than a "fist gesture".
在完成调整后的摄像头角度的存储后，显示设备不再跟随用户的移动位置调整摄像头的角度，以避免用户在将摄像头角度调整到最佳使用角度后，用户再次移动位置导致摄像头角度发生变化，影响用户的使用效果。After completing the storage of the adjusted camera angle, the display device will no longer adjust the camera angle following the user's moving position, so as to avoid the camera angle changing due to the user moving the position again after the user adjusts the camera angle to the optimal use angle. Affect the user's use effect.
而如果用户需要对摄像头角度的调整时，可能会出现调整的角度均不满意想要重新调整，或者，完成摄像头的当前次使用，需要控制摄像头的拍摄角度恢复至初始状态时，本发明实施例提供的显示设备，可对摄像头的拍摄角度进行重置。However, if the user needs to adjust the angle of the camera, it may happen that the adjusted angle is not satisfied and wants to re-adjust, or when the current use of the camera is completed and the shooting angle of the camera needs to be controlled to return to the initial state, the embodiment of the present invention The provided display device can reset the shooting angle of the camera.
此时用户可用户交互行为引导页面的指示作出第三手势，例如作出“拳头手势”时，产生重置指令，控制器响应重置指令，使得摄像头的拍摄角度恢复至初始状态，初始状态是指开启摄像头时(调整前)摄像头的初始角度值。At this time, the user can make a third gesture according to the instruction of the user interaction behavior guidance page. For example, when making a "fist gesture", a reset command is generated, and the controller responds to the reset command to restore the shooting angle of the camera to the initial state. The initial state refers to the reset command. The initial angle value of the camera when the camera is turned on (before adjustment).
在一些实施例中，为便于告知用户是否完成摄像头角度的重置，在控制器响应“拳头手势”产生的重置指令，对摄像头角度恢复至初始状态后，随即生成重置提示，并显示在预览画面中。用户在查看到预览画面中显示的重置提示后，即可确定控制器已完成摄像头角度的重置。In some embodiments, in order to inform the user whether the reset of the camera angle is completed, after the controller responds to the reset instruction generated by the "fist gesture" and restores the camera angle to the initial state, a reset prompt is generated immediately and displayed on the in the preview screen. After viewing the reset prompt displayed in the preview screen, the user can determine that the controller has completed the reset of the camera angle.
摄像头的拍摄角度被调整后，摄像头实时采集的预览画面也发生变化，预览画面中呈现的用户图像为摄像头按照新拍摄角度采集的新用户图像，并根据新用户图像生成新预览画面同步显示在显示器中，此时，显示器中展示的预览画面实时根据摄像头调整拍摄角度的变化产生相应变化。After the shooting angle of the camera is adjusted, the preview image captured by the camera in real time also changes. The user image displayed in the preview image is the new user image collected by the camera according to the new shooting angle, and a new preview image is generated based on the new user image and displayed on the monitor synchronously. , at this time, the preview image displayed on the display changes in real time according to the change of the camera's adjustment of the shooting angle.
可见，本实施例提供的显示设备，通过智能调整的方式调整摄像头的拍摄角度，即根据用户实时移动的位置，由控制器对用户改变的位置进行分析，确定出用户改变位置的方向，进而作为摄像头调整角度的转动方向，实现对摄像头拍摄角度的智能调整，无需用户过多的操作，操作简便，交互引导性好，以快速地调整摄像头角度，有效提升用户体验水平。It can be seen that the display device provided in this embodiment adjusts the shooting angle of the camera through intelligent adjustment, that is, according to the real-time moving position of the user, the controller analyzes the position changed by the user, determines the direction in which the user changes the position, and then acts as a The rotation direction of the camera adjustment angle realizes the intelligent adjustment of the camera shooting angle, without the need for excessive user operations, easy operation, and good interaction guidance, so as to quickly adjust the camera angle and effectively improve the user experience level.
