Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0029] The electronic device in the present application may be a terminal, and the terminal may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch or a smart charging station, etc., but is not limited thereto.

[0030] The following is an explanation of the pan-tilt camera control method provided by the present application. In this embodiment, it will be described from the perspective of the pan-tilt camera control device. In order to facilitate the explanation of the pan-tilt camera method of the present application, the following will be explained in detail with the pan-tilt camera device integrated in the terminal, that is, the terminal will be used as the execution subject for detailed explanation.

[0031] like Figure 1 As shown, Figure 1 This is a flow chart of an embodiment of a pan-tilt camera control method in an embodiment of the present application, and the pan-tilt camera control method includes:

[0032] 101. Obtain control interaction information of a target object for a control interaction area, and obtain a first mapping strategy and a second mapping strategy, wherein the control interaction information includes a current motion trajectory and a current motion speed of the target object.

[0033] The target object refers to an object that can control its own limbs to operate in the control interaction area. The type of the target object can be selected according to actual conditions, for example, the target object can be a user or a robot, and the embodiment of the present application does not limit this.

[0034] The target object can control its own limbs to directly operate on the control interaction area, for example, directly operate on the control interaction area, so that the terminal obtains the control interaction information of the target object for the control interaction area. Alternatively, the target object can also operate on the control interaction area through its own limb control input device, for example, operate on the control interaction area through its own limb control input device, so that the terminal obtains the control interaction information of the target object for the control interaction area.

[0035] The type of input device can be selected according to actual conditions. For example, the input device can be a mouse or a stylus pen, which is not limited in the embodiments of the present application.

[0036] The current motion trajectory of the target object refers to the trajectory of the target object's current motion with respect to the control interaction area. The current motion speed of the target object refers to the speed of the target object's current motion with respect to the control interaction area. For example, the form of motion may include sliding, then the current motion trajectory of the target object may include the sliding trajectory of the target object on the control interaction area at the current moment, and the current motion speed of the target object may include the sliding speed of the target object on the control interaction area at the current moment. For another example, the form of motion may include a combination of interactive operations such as clicking, sliding, and long pressing, then the current motion trajectory of the target object may include a combination of motion trajectories formed when the target object performs interactive operations such as clicking, sliding, and long pressing on the control interaction area at the current moment, and the current motion speed of the target object may include the motion speed inferred at the current moment based on the combined interactive operations such as clicking, sliding, and long pressing on the control interaction area.

[0037] The control interaction area refers to the area where the terminal can obtain the interactive operation of the target object, and the control interaction area can be used for the target object to control the PTZ camera. For example, the terminal can obtain the control interaction information of the target object through the touch area in the control interaction area, and the control interaction information may include the current motion trajectory and current motion speed of the target object.

[0038] Optionally, a specific interactive control operation can be configured for the touch area in the control interaction area to quickly trigger a specific function of the PTZ camera. For example, a double-click function can be configured for the touch area. When the user triggers a double-click operation in the touch area, the terminal can obtain control interaction information of the target object through the touch area in the control interaction area. The control interaction information may include double-click operation information. Correspondingly, the terminal can quickly trigger functions such as zooming, tracking, and shooting.

[0039] The position, proportion, presentation form, etc. of the touch area in the control interaction area can be configured according to actual conditions. For example, the touch area can be located below the control interaction area (for example, Figure 2 Alternatively, the touch area may be located above the control interaction area, which is not limited in the present application. For example, the touch area may occupy a fixed proportion of the control interaction area (for example, Figure 2Alternatively, the proportion of the touch area in the control interaction area may be adjusted accordingly according to different control interaction modes triggered by the target object, which is not limited in the present embodiment of the present application. For another example, the presentation form of the touch area in the control interaction area may be presented in a fixed position and proportion (for example, Figure 2 Alternatively, the presentation form of the touch area in the control interaction area may be that when no control interaction operation of the target object on the touch area is detected within a preset time, the touch area is displayed in thumbnail form until a trigger operation of the target object on the thumbnailed touch area is detected, and then the touch area is displayed in the form before thumbnail form. The embodiments of the present application are not limited here.

[0040] Optionally, after displaying the control interaction area, the terminal may suppress the screen from turning off, so that the target object can control the PTZ camera.

[0041] Optionally, the touch area in the control interaction area may include a touchpad and a first control control, and the touchpad may be used to obtain the current motion trajectory and the current motion speed. The type of the first control control may be set according to actual conditions, and the embodiment of the present application does not limit this.

[0042] For example, Figure 2 As shown, the first control control may include a mirror control, a gimbal reset control, a direction control, and a zoom control. Among them, the mirror control can be used to adjust the image to a mirror mode; the gimbal reset control can be used to quickly restore the gimbal to an initial position; the direction control can be used to finely adjust the rotation of the gimbal; and the zoom control can be used to zoom the image.

[0043] Optionally, the control interaction area may also include a control area for the pan-tilt camera, and the control area includes controls for controlling the pan-tilt camera. The controls may be set according to actual conditions, and the embodiments of the present application are not limited thereto.

[0044] For example, the control area and the controls for controlling the PTZ camera included in the control area are as follows: Figure 2 As shown. The overhead control indicates the overhead shooting mode, which can be used to control the PTZ camera to shoot overhead, for example, to achieve shooting by hanging the camera above the object being shot; the whiteboard control indicates the whiteboard mode, which can be used to control the PTZ camera to shoot the whiteboard; the Tracking control indicates the tracking mode, which can be used to control the PTZ camera to track the object, for example, to track the moving user; the Deskview control indicates the smart desktop mode, which can be used to display the objects on the desktop; the Preset Position control indicates the preset position, which provides 6 editable preset positions for quickly switching to the corresponding position.

[0045] The terminal can respond to the trigger operation on the pan-tilt camera client to display the control interaction area on the pan-tilt camera client, and then respond to the sliding operation of the target object on the control interaction area to obtain the current motion trajectory and current motion speed of the target object.

[0046] The type of the pan-tilt camera client can be set according to actual conditions. For example, the pan-tilt camera client can be in the form of an application, a mini-program or a web page, which is not limited in the embodiments of the present application.

[0047] The first mapping strategy refers to a strategy of mapping the current motion trajectory to a rotation angle parameter, and the second mapping strategy refers to a strategy of mapping the current motion speed to a rotation speed parameter. The longer the current motion trajectory, the larger the rotation angle parameter, and the faster the current motion speed, the larger the rotation speed parameter.

[0048] The forms of the first mapping strategy and the second mapping strategy can be set according to actual conditions. For example, the first mapping strategy can be a first mapping function, and the second mapping strategy can be a second mapping function, or the first mapping strategy can be a first mapping table, and the second mapping strategy can be a second mapping table, or the first mapping strategy can be a first mapping function, and the second mapping strategy can be a second mapping table, or the first mapping strategy can be a first mapping table, and the second mapping strategy can be a second mapping function. The embodiments of the present application are not limited here.

[0049] In some embodiments, obtaining the control interaction information of the target object for the control interaction area may include:

[0050] Get the target sampling time;

[0051] According to the target sampling time, control interaction information of the target object for the control interaction area is obtained.

[0052] The target sampling time refers to the interval for obtaining the control interaction information. For example, the target sampling time may be 30 milliseconds, which means that the terminal obtains the control interaction information every 30 milliseconds.

[0053] The target sampling time can be fixed or dynamically changing. When the target sampling time is dynamically changing, the process of obtaining the target sampling time can be:

[0054] Displaying a time setting page, the time setting page includes a time setting control;

[0055] In response to a trigger operation on a time setting control, the time corresponding to the trigger operation is used as a target sampling time.

[0056] For example, the time setting page can be Figure 3 As shown, Figure 3 The touch throttling in the example is a time setting control. The triggering operation of the time setting control may be, for example, a dragging operation of the time setting control. The time "15 milliseconds" at the end position of the dragging operation is used as the target sampling time.

[0057] Alternatively, when the target sampling time changes dynamically, the process of obtaining the target sampling time may also be:

[0058] Get the historical sliding data of the target object;

[0059] Predict the control interaction habit parameters of the target object based on historical sliding data;

[0060] Generate target sampling time based on control interaction habit parameters.

[0061] Among them, the historical sliding data can be analyzed to obtain the changes corresponding to the historical sliding data, and the control interaction habit parameters of the target object can be predicted based on the changes. Alternatively, the historical sliding data can be input into a trained prediction model for prediction to obtain the control interaction habit parameters of the target object.

[0062] In the related art, if the target sampling time is too long for the target object, the rotation of the gimbal camera may cause a time delay to the target object. If the target sampling time is too short for the target object, the gimbal camera may rotate frequently and consume high power.

[0063] For example, Figure 4 As shown, the target object is the target user. In 0-30 milliseconds, the target user's finger slides from position A to position B on the control interaction area. In 31-60 milliseconds, the target user's finger slides from position B to position C on the control interaction area. If the target sampling time is 60 milliseconds, the current motion trajectory collected is AC. AC is first mapped to obtain the rotation angle parameter corresponding to AC. The pan-tilt camera is controlled to rotate the rotation angle parameter corresponding to AC. The pan-tilt camera rotates once.

[0064] If the target sampling time is 30 milliseconds, the current motion trajectory AB is first collected, and the first mapping processing is performed on AB to obtain the rotation angle parameters corresponding to AB, and the gimbal camera is controlled to rotate the rotation angle parameters corresponding to AB. Then, the current motion trajectory BC is collected, and the first mapping processing is performed on BC to obtain the rotation angle parameters corresponding to BC, and the gimbal camera is controlled to rotate the rotation angle parameters corresponding to BC. At this time, the rotation angle parameters of the gimbal camera are actually the rotation angle parameters corresponding to AC. However, the gimbal camera rotates twice, and the power consumption is relatively high.

[0065] In an embodiment of the present application, historical sliding data of the target object is obtained, and the control interaction habit parameters of the target object are predicted based on the historical sliding data. Then, based on the control interaction habit parameters, a target sampling time is generated, so that the target sampling time changes as the control interaction habits of the target object change. This not only reduces the phenomenon of delay caused by the rotation of the pan-tilt camera to the target object, but also reduces the number of rotations of the pan-tilt camera, thereby reducing the power consumption of the pan-tilt camera.

[0066] 102. Perform a first mapping process on the current motion trajectory according to the first mapping strategy to obtain a rotation angle parameter of the pan / tilt camera.

[0067] The pan-tilt camera may include a pan-tilt and a shooting device, wherein the shooting device may be fixedly mounted on the pan-tilt or may be detachably mounted on the pan-tilt, which is not limited in the embodiments of the present application. The pan-tilt camera may drive the shooting device to rotate by controlling the pan-tilt to rotate on one or more axes. Optionally, the pan-tilt camera may specifically be a pan-tilt camera.

[0068] After obtaining the current motion trajectory and the first mapping strategy, the terminal may substitute the current motion trajectory into the first mapping strategy to perform the first mapping process, thereby obtaining the rotation angle parameter of the pan-tilt camera.

[0069] Optionally, the rotation angle parameter may include an angle and a rotation direction. Alternatively, the rotation angle parameter may also include only an angle, excluding the rotation direction of the pan-tilt camera. In this case, the rotation direction of the pan-tilt camera may be determined according to the movement direction of the target object in the control interaction area. The movement direction of the target object in the control interaction area may be used as the rotation direction of the pan-tilt camera, or the opposite direction of the movement direction of the target object in the control interaction area may be used as the rotation direction of the pan-tilt camera.

[0070] Optionally, when the rotation angle parameter does not include the rotation direction of the pan-tilt camera, before performing the first mapping process on the current motion trajectory according to the first mapping strategy to obtain the rotation angle parameter terminal of the pan-tilt camera, the terminal can display the direction selection page (for example, Figure 3As shown, the direction selection page and the time setting page can be the same page), the direction selection page can include a positive direction control and a negative direction control. In response to the selection operation of the positive direction control, the positive direction is used as the rotation direction of the pan-tilt camera, or, in response to the selection operation of the negative direction control, the negative direction is used as the rotation direction of the pan-tilt camera. After obtaining the current motion trajectory, the motion direction of the target object in the control interaction area can be obtained. If the rotation direction of the pan-tilt camera is the positive direction, the motion direction of the target object in the control interaction area is used as the rotation direction of the pan-tilt camera. If the rotation direction of the pan-tilt camera is the negative direction, the opposite direction of the motion direction of the target object in the control interaction area is used as the rotation direction of the pan-tilt camera.

[0071] Optionally, in the process of performing the first mapping process on the current motion trajectory according to the first mapping strategy, a step of smoothing the current motion trajectory using a smoothing algorithm may be included.

[0072] 103. According to the second mapping strategy, perform a second mapping process on the current motion speed to obtain a rotation speed parameter of the pan / tilt camera.

[0073] The second mapping strategy may include at least one. When the second mapping strategy includes one, the terminal may directly substitute the current motion speed into the second mapping strategy for second mapping processing to obtain the rotation speed parameter of the pan-tilt camera.

[0074] When the second mapping strategy includes multiple ones, a target second mapping strategy can be screened out from the multiple second mapping strategies according to the degree to which the pan-tilt camera follows the target object, and then the second mapping processing is performed on the current motion speed according to the target second mapping strategy. At this time, each second mapping strategy can be set to correspond to a different sensitivity type, and the sensitivity type can indicate the degree to which the pan-tilt camera follows the target object (for example, the following degree can be understood as the hand-following degree of the pan-tilt camera). According to the second mapping strategy, the second mapping processing is performed on the current motion speed to obtain the rotation speed parameter of the pan-tilt camera, which can include:

[0075] Determine the target sensitivity type;

[0076] Filtering out a second mapping strategy that matches the target sensitivity type from a plurality of second mapping strategies to obtain a target second mapping strategy;

[0077] According to the target second mapping strategy, the current motion speed is subjected to second mapping processing to obtain the rotation speed parameter of the pan / tilt camera.

[0078] Among them, when the sensitivity type indicates that the degree of following the target object of the gimbal camera is higher, the rotation speed parameter of the gimbal camera is larger, and when the sensitivity type indicates that the degree of following the target object of the gimbal camera is lower, the rotation speed parameter of the gimbal camera is smaller.

[0079] In an embodiment of the present application, a target sensitivity type is determined; a second mapping strategy matching the target sensitivity type is screened out from a plurality of second mapping strategies to obtain a target second mapping strategy; according to the target second mapping strategy, a second mapping process is performed on the current motion speed to obtain a rotation speed parameter of the gimbal camera, so as to determine the rotation speed parameter of the gimbal camera according to the degree to which the gimbal camera follows the target object, so that for the same current motion speed, when the degree to which the gimbal camera follows the target object is different, the rotation speed parameter of the gimbal camera is also different.

[0080] Optionally, the target sensitivity type may be determined according to the current motion speed, or the target sensitivity type may be determined according to the rotation angle parameter. When the target sensitivity type is determined according to the current motion speed, the process of determining the target sensitivity type may be:

[0081] Acquire at least two speed types, where the sensitivity types corresponding to the speed types indicate the degree to which the PTZ camera follows the target object when the target object is at a motion speed corresponding to the speed type;

[0082] Determine the speed type corresponding to the current motion speed and obtain the target speed type;

[0083] The sensitivity type corresponding to the target speed type is determined as the target sensitivity type.

[0084] Among them, a speed type can be associated with a sensitivity type, and the sensitivity type associated with the speed type is the sensitivity type corresponding to the speed type.

[0085] The faster the movement speed, the higher the degree of following the target object indicated by the speed type corresponding to the movement speed and the sensitivity type corresponding to the movement speed; the slower the movement speed, the lower the degree of following the target object indicated by the speed type corresponding to the movement speed and the sensitivity type corresponding to the movement speed.

[0086] The speed type can be divided according to the speed threshold. For example, when the speed types include two, the speed type can be a high speed type and a low speed type, the movement speed corresponding to the high speed type is a movement speed greater than the speed threshold, and the movement speed corresponding to the low speed type is a movement speed less than or equal to the speed threshold. For another example, when the speed types include three, the speed types can be a high speed type, a medium speed type and a low speed type, the movement speed corresponding to the high speed type is a movement speed greater than the first speed threshold, the movement speed corresponding to the medium speed type is a movement speed less than or equal to the first speed threshold and greater than the second speed threshold, and the movement speed corresponding to the low speed type is a movement speed less than or equal to the second speed threshold.

[0087] When the speed type includes two, after obtaining the current movement speed, the terminal can compare the current movement speed with the speed threshold. If the current movement speed is greater than the speed threshold, the speed type corresponding to the current movement speed is the high speed type, that is, the target speed type is the high speed type. If the current movement speed is less than the speed threshold, the speed type corresponding to the current movement speed is the low speed type, that is, the target speed type is the low speed type.

[0088] Optionally, the terminal may display a speed threshold setting page, the speed threshold setting page including a threshold setting control, and the speed threshold is acquired in response to a triggering operation on the threshold setting control.

[0089] For example, Figure 3 As shown, the speed threshold setting page and the time setting page can be the same page. Figure 3 The speed limit value control in is a threshold setting control. In response to a drag operation on the threshold setting control, the terminal can use the value 16 at the stop position of the drag operation as the speed threshold.

[0090] In an embodiment of the present application, at least two speed types are obtained, and the sensitivity type corresponding to the speed type indicates the degree to which the gimbal camera follows the target object when the target object is at a movement speed corresponding to the speed type; the speed type corresponding to the current movement speed is determined to obtain the target speed type; the sensitivity type corresponding to the target speed type is determined as the target sensitivity type, so as to change the degree to which the gimbal camera follows the target object according to the current movement speed.

[0091] Optionally, a speed type may correspond to at least one sensitivity coefficient. When a speed type corresponds to a sensitivity coefficient, after the terminal selects a second mapping strategy that matches the target sensitivity type from multiple second mapping strategies and obtains the target second mapping strategy, it can directly perform second mapping processing on the current motion speed according to the target second mapping strategy to obtain the rotation speed parameter of the pan-tilt camera.

[0092] When a speed type corresponds to multiple sensitivity coefficients, the current motion speed can also be subjected to a second mapping process according to the sensitivity coefficient. At this time, before the current motion speed is subjected to a second mapping process according to the target second mapping strategy and the rotation speed parameter of the pan / tilt camera is obtained, the following may also be included:

[0093] Displaying a sensitivity setting page, the sensitivity setting page including at least two sensitivity setting controls corresponding to the speed types;

[0094] In response to a trigger operation on a sensitivity setting control, a sensitivity coefficient corresponding to the speed type is determined, the sensitivity coefficient indicating a following level of the target object by the gimbal camera when the target object is at a moving speed corresponding to the speed type.

[0095] Among them, a following degree can be divided into multiple following sub-degrees, and one following sub-degree corresponds to a following level. When the target object is at a moving speed corresponding to the speed type, the following level in the following degree of the PTZ camera for the target object is higher, indicating that the following sub-degree in the following degree indicated by the sensitivity type corresponding to the speed type of the PTZ camera is higher, and when the target object is at a moving speed corresponding to the speed type, the following level in the following degree of the PTZ camera for the target object is lower, indicating that the following sub-degree in the following degree indicated by the sensitivity type corresponding to the speed type of the PTZ camera is lower.

[0096] For example, the sensitivity setting page can be Figure 3 As shown, the sensitivity setting page and the time setting page are the same page, and the speed type can include a high speed type and a low speed type. Figure 3 The touch low speed sensitivity in is the sensitivity setting control corresponding to the low speed type. Figure 3 The touch high speed sensitivity is the sensitivity setting control corresponding to the high speed type. In response to the dragging operation of the sensitivity setting control corresponding to the low speed type, the value 3 is used as the sensitivity coefficient corresponding to the low speed type. In response to the dragging operation of the sensitivity setting control corresponding to the high speed type, the value 5 is used as the sensitivity coefficient corresponding to the low speed type.

[0097] At this time, according to the target second mapping strategy, the current motion speed is subjected to second mapping processing to obtain the rotation speed parameter of the pan / tilt camera, which may include:

[0098] According to the sensitivity coefficient corresponding to the target speed type, the current movement speed is adjusted to obtain the adjusted movement speed;

[0099] According to the target second mapping strategy, the adjusted motion speed is subjected to second mapping processing to obtain the rotation speed parameter of the pan-tilt camera.

[0100] For example, the sensitivity coefficient corresponding to the target speed type may be multiplied by the current movement speed to obtain the adjusted movement speed, or a speed adjustment parameter associated with the sensitivity coefficient corresponding to the target speed type may be determined, and the speed adjustment parameter may be multiplied by the current movement speed to obtain the adjusted movement speed.

[0101] Alternatively, a second mapping strategy may include multiple second sub-mapping strategies, and different sensitivity systems correspond to different second sub-mapping strategies, that is, the target second mapping strategy includes multiple second sub-mapping strategies. At this time, according to the target second mapping strategy, the current motion speed is subjected to second mapping processing to obtain the rotation speed parameter of the pan-tilt camera, which may include:

[0102] Selecting a second sub-mapping strategy that matches the sensitivity coefficient corresponding to the target speed type from the second sub-mapping strategy of the target second mapping strategy to obtain the target second sub-mapping strategy;

[0103] According to the target second sub-mapping strategy, the current motion speed is subjected to second mapping processing to obtain the rotation speed parameter of the pan-tilt camera.

[0104] When the target sensitivity type is determined according to the rotation angle parameter, the process of determining the target sensitivity type may be:

[0105] Acquire at least two preset angle intervals, where the sensitivity types corresponding to the preset angle intervals indicate the degree to which the PTZ camera follows the target object when the rotation angle parameter is within the preset angle interval;

[0106] The preset angle interval where the rotation angle parameter is located is determined as the target preset angle interval;

[0107] The sensitivity type corresponding to the target preset angle range is determined as the target sensitivity type.

[0108] Among them, the larger the rotation angle parameter, the larger the preset angle interval, the higher the degree of following the target object indicated by the sensitivity type corresponding to the preset angle interval, the larger the rotation speed parameter of the gimbal camera, the smaller the rotation angle parameter, the smaller the preset angle interval, the lower the degree of following the target object indicated by the sensitivity type corresponding to the preset angle interval, and the smaller the rotation speed parameter of the gimbal camera.

[0109] In an embodiment of the present application, at least two preset angle intervals are obtained, and the sensitivity type corresponding to the preset angle interval indicates the degree to which the gimbal camera follows the target object when the rotation angle parameter is in the preset angle interval; the preset angle interval in which the rotation angle parameter is located is determined as the target preset angle interval; the sensitivity type corresponding to the target preset angle interval is determined as the target sensitivity type, so that when the rotation angle parameter is larger, the rotation speed parameter is larger, and when the rotation angle parameter is smaller, the rotation speed parameter is smaller.

[0110] Optionally, when the target sensitivity is determined according to the rotation angle parameter and the current motion speed at the same time, the process of determining the target sensitivity may be:

[0111] Acquire at least two speed types, where the sensitivity types corresponding to the speed types indicate the degree to which the PTZ camera follows the target object when the target object is at a motion speed corresponding to the speed type;

[0112] Determine the speed type corresponding to the current motion speed and obtain the target speed type;

[0113] Determine the sensitivity type corresponding to the target speed type as the first target sensitivity type;

[0114] Acquire at least two preset angle intervals, where the sensitivity types corresponding to the preset angle intervals indicate the degree to which the PTZ camera follows the target object when the rotation angle parameter is within the preset angle interval;

[0115] The preset angle interval where the rotation angle parameter is located is determined as the target preset angle interval;

[0116] Determine the sensitivity type corresponding to the preset angle interval of the target as the second target sensitivity type;

[0117] A target sensitivity type is determined according to the first target sensitivity type and the second target sensitivity type.

[0118] Among them, the priority of the first target sensitivity type and the priority of the second target sensitivity type can be determined. If the priority of the first target sensitivity type is higher than the priority of the second target sensitivity type, the first target sensitivity type is used as the target sensitivity type. If the priority of the first target sensitivity type is lower than the priority of the second target sensitivity type, the second target sensitivity type is used as the target sensitivity type.

[0119] Alternatively, an intermediate sensitivity type between the first target sensitivity type and the second target sensitivity type may be used as the target sensitivity type. For example, if the first target sensitivity type is a high speed type and the second target sensitivity type is a low speed type, the intermediate speed type may be used as the target sensitivity type.

[0120] Alternatively, the current emotion of the target object may be acquired, and the sensitivity type that matches the current emotion between the first target sensitivity type and the second target sensitivity type is used as the target sensitivity type.

[0121] For example, the degree to which the gimbal camera follows the target object indicated by the first target sensitivity type is higher than the degree to which the gimbal camera follows the target object indicated by the second target sensitivity type. If the current emotion is a calm emotion, the second target sensitivity type is used as the sensitivity type that matches the current emotion. If the current emotion is an impatient emotion, the first target sensitivity type is used as the sensitivity type that matches the current emotion.

[0122] Optionally, in the process of performing the second mapping process on the current motion speed according to the second mapping strategy, a step of smoothing the current motion speed using a smoothing algorithm may be included.

[0123] 104. Control the PTZ camera to rotate according to the rotation speed parameter and the rotation angle parameter.

[0124] After obtaining the rotation speed parameter and the rotation angle parameter, the terminal may send the rotation speed parameter and the rotation angle parameter to the pan-tilt camera, and the pan-tilt camera then rotates the rotation angle parameter according to the rotation speed parameter.

[0125] The terminal may send the rotation speed parameter and the rotation angle parameter to the pan-tilt camera in a wired or wireless manner. When the terminal sends the rotation speed parameter and the rotation angle parameter to the pan-tilt camera in a wireless manner, the terminal and the pan-tilt camera may be located in the same wireless local area network.

[0126] In an embodiment of the present application, control interaction information of the target object for the control interaction area is obtained, as well as a first mapping strategy and a second mapping strategy, wherein the control interaction information includes the current motion trajectory and the current motion speed of the target object; according to the first mapping strategy, a first mapping process is performed on the current motion trajectory to obtain a rotation angle parameter of the gimbal camera; according to the second mapping strategy, a second mapping process is performed on the current motion speed to obtain a rotation speed parameter of the gimbal camera; the gimbal camera is controlled to rotate the rotation angle parameter according to the rotation speed parameter, so as to control the rotation of the gimbal camera according to the current motion trajectory and the current motion speed of the target object. When the current motion trajectory and the current motion speed are different, the rotation angle parameter and the rotation speed parameter of the gimbal camera are also different, which gives the user a more intuitive operating experience and reduces the difficulty of controlling the rotation of the gimbal camera.

[0127] In some embodiments, controlling the pan / tilt camera to rotate the rotation angle parameter according to the rotation speed parameter may include:

[0128] Get the preset rotation speed threshold;

[0129] If the rotation speed parameter is less than or equal to the preset rotation speed threshold, the pan / tilt camera is controlled to rotate the rotation angle parameter according to the rotation speed parameter.

[0130] If the rotation speed parameter is greater than the preset rotation speed threshold, the pan / tilt camera is controlled to rotate the rotation angle parameter according to the preset rotation speed threshold.

[0131] When the rotation speed parameter of the pan-tilt camera is too large, if the pan-tilt camera rotates the rotation angle parameter according to the rotation speed parameter, the pan-tilt camera will cause shaking. Therefore, in the embodiment of the present application, a preset rotation speed threshold is obtained; if the rotation speed parameter is less than or equal to the preset rotation speed threshold, the pan-tilt camera is controlled to rotate the rotation angle parameter according to the rotation speed parameter. If the rotation speed parameter is greater than the preset rotation speed threshold, the pan-tilt camera is controlled to rotate the rotation angle parameter according to the preset rotation speed threshold to avoid the shaking of the pan-tilt camera due to too fast rotation speed.

[0132] As can be seen from the above, the present application obtains the control interaction information of the target object for the control interaction area, and obtains the first mapping strategy and the second mapping strategy, wherein the control interaction information includes the current motion trajectory and the current motion speed of the target object; according to the first mapping strategy, the current motion trajectory is subjected to a first mapping processing to obtain the rotation angle parameter of the gimbal camera; according to the second mapping strategy, the current motion speed is subjected to a second mapping processing to obtain the rotation speed parameter of the gimbal camera; the gimbal camera is controlled to rotate the rotation angle parameter according to the rotation speed parameter, so as to realize the control of the rotation of the gimbal camera according to the current motion trajectory and the current motion speed of the target object, thereby reducing the difficulty of controlling the rotation of the gimbal camera.
