Referring to fig. 2, an application scenario diagram of the camera control method provided in the embodiment of the present application includes a user 200, a terminal 201, a background server 202, and a camera 203.

In the method, a plurality of users 200 and terminals 201 may exist, wherein each user 200 may select a control instruction through a user interface on the terminal 201, and then the terminal 201 sends the control instruction to the backend server 202 for analysis, and after the backend server 202 analyzes the control instruction sent by each user 200, one control instruction to be executed is obtained according to a priority corresponding to each control instruction and sent to the camera 203.

The terminal 201 and the backend server 202 may be communicatively connected through a communication network, which may be a local area network, a wide area network, or the like.

It should be noted that the backend server 202 can also implement control over a plurality of cameras 203. The application mainly discusses the control scene of a plurality of users to the same camera.

It should be noted that the application scenario shown in fig. 2 is only an example, and the embodiment of the present application does not limit this.

In the field of hospital digitization and informatization, when a plurality of operation classroom and a plurality of users log in an operation teaching system at the same time, a camera is controlled together; if the user A controls the camera to move leftwards, a leftward instruction is sent, and then the camera moves leftwards; at the moment or after the user A sends a left instruction, the user B controls the camera to move rightwards or upwards, and then sends a right or upwards instruction; therefore, the overall motion state of the camera is as follows: move to the left and then to the right or upward. The inventors have found that, in such a scenario, if a control command is transmitted a plurality of times in succession, there is a problem that the lifetime is shortened due to frequent rotation, seizure, long-term consumption, and the like.

Fig. 3 is a schematic diagram of an application principle according to an embodiment of the present application. The part can be implemented by a part of modules or functional components of the communication terminal shown in fig. 1, and only the main components will be described below, while other components, such as a memory, a controller, a control circuit, etc., will not be described herein again.

As shown in fig. 3, the application environment may include a user interface 310 to be waited for a user operation provided via an input and output unit, a display unit 320 for displaying the user interface, and a processor 330 controlling display of the user interface.

The display unit 320 may include a display panel 321, a backlight assembly 322. The display panel 321 is configured to display an image, the backlight assembly 322 is disposed at the back of the display panel 321, and the backlight assembly 322 may include a plurality of backlight partitions (not shown), each of which may emit light with different brightness to illuminate the display panel 321.

The processor 330 may be configured to control the backlight brightness of each backlight partition in the backlight assembly 322 and cause each backlight partition in the backlight assembly to light the display panel 321 according to the corresponding backlight brightness.

The processor 330 may include an analysis unit 331 and a transmission unit 332. The analysis unit 331 may be configured to analyze the control instructions received in a specified time period, and obtain one control instruction to be executed according to a priority corresponding to each control instruction; the control instruction is used for controlling the camera to execute corresponding actions. The sending unit 332 is configured to send the control instruction to be executed to the camera for execution.

In view of this, the present application provides a camera control method, which mainly includes: in a scene for controlling the camera, a plurality of users may send control instructions to the camera, and because a plurality of control instructions sent by the users are available and may be sent simultaneously, a series of problems of shortening the service life of the camera caused by the fact that the camera needs to execute each control instruction are avoided; the method and the device for analyzing the control commands realize the analysis of the control commands, so that the control commands to be executed are obtained according to the priorities corresponding to the control commands and are sent to the camera for execution. Through the implementation mode, the camera can move orderly according to the control instruction or the synthesized control instruction in the appointed time period, and the movement disorder of the camera is avoided because each control instruction is not required to be executed, so that the abrasion of the camera is avoided, and the service life of the camera is prolonged.

Based on the above description, fig. 4 shows a detailed schematic flow chart of a camera control method provided in the embodiment of the present application, where the flow chart specifically includes:

step 401: analyzing the control instructions received in a specified time period, and obtaining a control instruction to be executed according to the priority corresponding to each control instruction; the control instruction is used for controlling the camera to execute corresponding actions.

Step 402: and sending the control instruction to be executed to the camera for execution.

One possible scenario for analyzing the control instructions received within the specified time period is that the received control instructions all have corresponding priorities; therefore, for the control instructions received in the designated time period, one control instruction to be executed can be determined according to the priority of each control instruction.

In one possible implementation manner of determining the priority corresponding to the control instruction during implementation, the priority of the control instruction sent by the user account is determined by configuring the priority for each user account. In some exemplary embodiments, the prioritizing of the user account may be performed in a relatively simple configuration, including: the priority of the user account has a plurality of levels (such as high priority, medium priority, low priority, etc.), and the present application is not limited herein. A correspondence between a user account and its corresponding priority is shown in table 1:

TABLE 1

User account	Priority level
		User A	High priority
User B	Low priority
		User C	Low priority

The priority of the user a can be determined as a high priority from table 1, and therefore, if each control instruction sent by the user a, the user B, and the user C is received within a specified time period, the determination is performed according to the priority level, where the level of the user a is the highest, the control instruction sent by the user a is used as a control instruction to be executed, and is further sent to the camera for execution. In addition, the configuration manner and the corresponding relationship of the user account priority in table 1 are only one possible implementation manner provided by the embodiment of the present application, and are not used to limit the present application, for example, the configuration manner of the user account priority may further include: the first priority, the second priority, the third priority and the like can determine the configuration mode of the user account priority according to needs.

It should be noted that, there may be a case that each user account logs in or logs out at any time, and after the background server recognizes the login or logout signal of the user account, the priority of the user account in a specified time period may change. For example, user B, user C log out and user D logs in for a specified period of time, where user D may have a higher priority than user A, then user D may be determined to be a high priority user A with a low priority for the specified period of time. Of course, in some exemplary embodiments, a plurality of specific priorities corresponding to different user accounts may be configured, and a plurality of possible priorities of the plurality of user accounts may be determined by the specific priorities.

In addition, in some exemplary embodiments, an instruction stack is established, and then the instruction analyzer analyzes the control instructions in the instruction stack, so as to obtain a control instruction to be executed, and send the control instruction to be executed to the camera for execution.

Specifically, for example, each control instruction sent by each user account is stored in the instruction stack in combination with the level of the priority corresponding to the control instruction. One possible implementation of the instruction stack is shown in table 2:

TABLE 2

Receiving sequence of control instructions	Control instruction	Priority level of user account
			6	End up	All in one
5	End up	Is low in
			4	Up	Is low in
3	To the left	Height of
			2	Start of	Is low in
1	Start of	Height of

Wherein "1-6" in table 2 indicates the receiving order of the control instructions in the stack, wherein the ordering of "1" indicates the control instruction received first. Through the analysis of the command analyzer, it can be determined that the control commands for controlling the camera motion include two control commands ordered as "3", "4" as shown in table 2. And, by combining the judgment of the priority, since the priority of the control instruction ranked as "3" is higher, the control instruction ranked as "3" to the left "is sent to the camera as the control instruction to be executed, so that the camera executes the action to the left.

In addition, when determining a control instruction to be executed according to the priority of each control instruction, in some exemplary embodiments, comparing the priorities of the control instructions to determine the control instruction with the highest priority, there are several possible implementation scenarios including:

scene 1: first, a first control instruction received in a specified time period can be stored in the instruction stack; and if the control instruction is received again in the appointed time period, comparing the control instruction received again with the priority of the control instruction in the instruction stack.

If the comparison result shows that the priorities are the same, storing the control instruction received again into the instruction stack; if the comparison result is that the priority of the control instruction received again is the highest, filtering out the control instruction which is lower than the priority of the control instruction received again in the instruction stack; and when the timing of the specified time period is ended, determining that the control instruction in the instruction stack is the control instruction with the highest priority.

It should be noted that the designated time period is set, and in some exemplary embodiments, the designated time period is set as the starting time point (e.g. T1) when the instruction stack receives the first control instruction for controlling the movement of the camera except the control instruction indicating "start", and then the designated time period is set as the time threshold (e.g. T) preset in the system. Therefore, it can be understood that the control instruction with the highest priority within the specified time period of T1 to T1+ T is determined. Or, the specified time period is a specified time period specified by the system according to the current state of the camera or the system.

In a possible embodiment, if no other control command is received in the specified time period, the first received control command is directly executed. In another possible embodiment, if a new control instruction is received again at this specified time period, the new control instruction is compared with the control instruction currently stored in the instruction stack. One possible implementation of the comparison is shown in table 3:

TABLE 3

If the control instruction is received again, if the control instruction received again is higher than the priority of the control instruction currently stored in the instruction stack or the priority of the control instruction received again is the same as the priority of the control instruction currently stored in the instruction stack, the control instruction currently stored in the instruction stack is shifted out, and the control instruction received again is stored in the instruction stack; for example, sequence number 1 in table 3 corresponds to the content of the row, or sequence number n corresponds to the content of the row. On the contrary, if the control instruction received again has lower priority than the control instruction currently stored in the instruction stack, filtering the control instruction received again, namely disregarding the control instruction received again; for example, the content of the row corresponding to the sequence number 2 in table 3. In addition, prompt information such as "operation occupation" and the like can be sent to the user account corresponding to the low-priority control instruction. For example, referring to fig. 5, an interface display diagram provided according to the embodiment of the present application is shown, where a user pops up a prompt message of "operation occupied" through a display panel within a specified time period after selecting a control instruction or after the specified time period is over, so that the user can determine that the control instruction is not executed this time, and then the user can wait for a certain time to reselect. By comparison of the control instructions in the instruction stack, it can be determined that the control instruction at the end of the specified time period in time in the instruction stack is the highest priority control instruction or the same priority and most recently received control instruction.

And after the appointed time period is ended, sending the control instruction currently stored in the instruction stack to the camera as the control instruction to be executed. Furthermore, after the execution of the control instruction by the camera is completed, a control instruction indicating "end" may be sent to the system, so that the system clears the instruction stack and waits for the reception of the next control instruction.

Scene 2: and when one control instruction with the highest priority exists, taking the control instruction with the highest priority as the control instruction to be executed.

When the control instruction to be executed is determined, all the control instructions in the specified time period can be analyzed, so that the control instruction with the highest priority is determined. If the form of the instruction stack is adopted, in some exemplary embodiments, all instructions received within a specified time period are stored in the instruction stack, and the control instruction with the highest priority in all control instructions in the instruction stack is determined through analyzing the priority of each control instruction in the instruction stack.

Wherein, only one control instruction is available if the priority is the highest. For example, the user accounts have only high priority and low priority, and in a specified time period, only one control instruction with high priority is determined through analysis, and the other control instructions are the control instructions sent by the user accounts with low priority, so that the control instructions with high priority are taken as the control instructions to be executed.

Scene 3: when there are a plurality of control instructions with the highest priority, selecting one control instruction from the plurality of control instructions with the highest priority as the control instruction to be executed, or combining the plurality of control instructions with the highest priority into one control instruction as the control instruction to be executed.

In this case, a plurality of control commands having the highest priority may exist after the analysis, corresponding to scenario 2. In one embodiment, one control instruction is selected from the determined plurality of highest priority control instructions as the control instruction to be executed.

One possible implementation is to classify a plurality of control commands with the highest priority, wherein the control commands requesting the camera to execute the same action are of one class; determining the number of control instructions contained in each type; when one class with the largest number of control instructions exists, determining the control instructions of the class as the control instructions to be executed; when the class with the largest number of control instructions is provided with a plurality of classes, combining a plurality of control instructions with the highest priority contained in the plurality of classes into one control instruction as the control instruction to be executed.

For example, the plurality of highest priority control instructions includes: "Up", "up", "left", two of the "up" control commands are identified as a first category and "left" is identified as a second category; then, because the first class includes two control commands and the second class includes one control command, the control command represented by the first class is used as the control command to be executed, that is, the "leftward" control command is sent to the camera for execution.

Or, for example, a plurality of highest priority control instructions, including: "up", "left", then it may be determined at this point that the first type of "up" control command includes two, and the second type of "left" control command includes two as well. In one embodiment, the two types of control instructions are combined into one control instruction as the control instruction to be executed.

And combining the control instructions with the highest priority into one control instruction to be used as the control instruction to be executed. In specific implementation, the merging instructions corresponding to the control instructions with the highest priority can be searched in a pre-constructed and stored instruction dictionary; and determining the searched merging instruction as the merged control instruction. For example, the combined instruction of the "up" and "left" control instructions is found from the instruction dictionary as the "top left" control instruction, and therefore the control instruction is sent to the camera for execution as the control instruction to be executed. Wherein, a possible construction method of the instruction dictionary is shown in table 4:

control instructions to be merged	Merged control instructions in instruction dictionary
		Upwards and leftwards	Upper left of
Upwards and rightwards	Upper right part
		Down and left	Left lower part
Down and to the right	Lower right

It should be noted that the merged control command in the command dictionary in table 4 is only one possible implementation and is not a unique limitation on the command dictionary.

In addition, if the merging instruction corresponding to the control instructions with the highest priority is not found in the pre-constructed and stored instruction dictionary, selecting one control instruction from the control instructions with the highest priority as the control instruction to be executed, which may further include several possible implementation manners, as follows:

mode 1: and selecting the last received control instruction from the control instructions with the highest priority as the control instruction to be executed.

For example, if the plurality of control commands with the highest priority includes: "upward", "downward"; since the merged control command is not found in the command dictionary, the "down" control command is taken as the control command to be executed since the "down" control command was received last. In this embodiment, the possible reason is that different control instructions are sent by the same user, where the control instruction sent first is an error instruction, and therefore the control instruction sent later is taken as the last control instruction to be executed.

Mode 2: and selecting the control instruction received firstly as the control instruction to be executed.

Similarly, the corresponding method 1 may also use the control instruction received first as the control instruction to be executed. The possible reason is that the same user may first want to execute the "up" control command and then execute the "down" control command. If the user does not monitor or receive the downward control instruction executed by the camera after the designated time period is over, the user can choose to send the control instruction again.

Mode 3: and randomly selecting a control instruction as the control instruction to be executed.

By the camera control method, the control instruction which needs to be executed by the camera can be selectively sent to the camera if a plurality of control instructions are received in the specified time period. By this method, only one control instruction is executed, compared to the manner in which all the received control instructions need to be executed within a specified time period in the related art. Therefore, the camera avoids a series of problems of shortening the service life of the camera caused by multiple movements in a short time and the like.

To better understand the present application, first, an implementation process of controlling a camera by only one user is introduced, and referring to fig. 6, a flowchart of a camera control method provided in an embodiment of the present application is shown, where the process includes:

step 601: a control instruction indicating "start" is received.

Step 602: and acquiring a set specified time period (for example, the duration of the specified time period is T).

Step 603: a control instruction configured for camera movement is received.

If the designated time period is set within the time period T for sending the control command, the time for sending the control command needs to be recorded (T1). Alternatively, the start time or the end time of the specified time period is recorded.

Step 604: it is determined whether a specified time period has arrived.

If the specified time period has not been reached, continue to step 605, and if the specified time period has been reached, continue to step 606.

Step 605: and continuing to wait.

And returns to execution step 604.

Step 606: and sending the control instruction to the camera.

Step 607: a control command is received indicating "end".

Referring to fig. 7, another schematic flow chart of a camera control method provided in an embodiment of the present application is shown, where in fig. 7, a possible flow of controlling a camera by multiple users includes:

step 701: control instructions indicating "start" sent by multiple users are received.

Step 702: an instruction stack of control instructions is generated.

The embodiment of generating the instruction stack is only one possible embodiment of the present application, and one control instruction to be executed, which is used to control the movement of the camera, may also be used to determine a plurality of control instructions within a specified time period in the present application.

Step 703: an instruction analyzer of the system monitors the instruction stack for message changes in control instructions in real time.

Step 704: the command analyzer aggregates the number and levels of different control commands.

Step 705: and judging whether a control instruction with high priority exists or not.

If yes, go on to step 706, otherwise go to step 706'.

Step 706: it is determined whether there is only one control instruction of high priority.

If yes, go to step 711. Otherwise, execution continues at step 707.

Step 706': control instructions in the instruction stack that are all low priority are determined. Execution then continues at step 708.

Step 707: a plurality of high priority control instructions are recorded and low priority control instructions are ignored.

Wherein ignoring the low priority control instructions in some exemplary embodiments moves the low priority control instructions out of the instruction stack.

Step 708: the instruction analyzer aggregates the number of control instructions within the class of different control instructions of the priority.

Step 709: and judging whether the number of the control instructions of one class is the largest in each class.

If yes, proceed to step 710. Otherwise, step 710a is performed.

Step 710: and determining the control instruction of the class as the control instruction to be executed according to the majority principle.

Step 710 a: and determining the synthesized control instruction of the same class of the control instruction in the instruction dictionary.

Step 710 b: and determining the synthesized control instruction as the control instruction to be executed.

Step 711: and when the specified time period is reached, sending the control instruction to be executed to the camera for execution.

Step 712: a control command indicating "end" is received and the control command received within a specified time period is cleared.
