Description

Technical Field

[0001] The invention relates to a system and method for regulating camera control priority, belonging to the field of camera pan / tilt control. Background Art

[0002] In today's digital age, video surveillance systems play a vital role in many fields such as security monitoring, traffic management, and telemedicine. As technology develops, these systems are becoming more and more complex and feature-rich. Among them, pan-tilt control technology allows users to remotely control the position of the camera to achieve precise monitoring of a specific area. However, as the number of users increases, especially in environments that require multi-person collaboration, how to efficiently and fairly manage the control of the same camera pan-tilt has become a problem that needs to be solved.

[0003] In existing technologies, when multiple users try to control the same camera pan / tilt at the same time, there is often a phenomenon of competition for control. This disorderly competition not only reduces monitoring efficiency, but may also lead to mistakes at critical monitoring moments. For example, in an emergency, a theoretically high-priority user (such as a security officer) may not be able to adjust the camera angle in time because the control is occupied by a low-priority user, thereby delaying the response to the emergency.

[0004] In addition, existing systems often lack effective mechanisms to manage and coordinate control requests from multiple users. This leads to an uneven distribution of control rights, where the needs of high-priority users cannot be met in a timely manner, while low-priority users may frequently interfere with the control process. These problems not only affect the performance of the monitoring system, but also reduce users' trust and satisfaction with the system. Summary of the invention

[0005] The present invention proposes a system and method for regulating camera control priority. By introducing an advanced priority mechanism and aspect-oriented programming (AOP) technology, control requests on the camera control interface are intercepted and processed, and orderly management of control permissions is achieved, thereby solving the problem of camera control contention in the prior art.

[0006] A system for controlling camera control priority includes a user priority configuration module, an AOP request interception module, a locking mechanism module, a priority determination module and a queuing module. The user priority configuration module, the AOP request interception module and the priority determination module are connected in sequence, the priority determination module and the queuing module are bidirectionally connected, and the locking mechanism module is connected to the AOP request interception module and the priority determination module at the same time.

[0007] User priority configuration module, used to assign camera control priority when creating a user, and the priority information is stored in the system;

[0008] AOP request interception module, used to intercept control requests on the camera control interface, check the current camera status, controller and lock time;

[0009] The locking mechanism module is used to record the current camera controller and the locking time, manage the countdown of the locking time, and thus determine whether to terminate the current controller's right of use;

[0010] The priority determination module is used to determine whether the user has the authority to seize control and make decisions based on the user priority and lock time;

[0011] The queuing module is used to queue the grabbers according to the user priority and grabbing sequence, and automatically initiate a "whether to control" query to the grabber at the front of the queue when the controller is missing.

[0012] A method for controlling camera control priority, based on the above-mentioned system for controlling camera control priority, the method for controlling camera control priority comprises the following steps:

[0013] S100, when a user creates an account in the system, the corresponding camera control priority is assigned according to the user's identity and authority and the priority information is stored for subsequent use in determining the control authority;

[0014] S200, using AOP technology, intercepting the control request when the snatcher sends the control request, and checking whether the current camera has a controller, if not, granting the snatcher the right to use; otherwise, checking the control state, controller and locking time of the current camera, and executing S300;

[0015] S300, determining whether the current camera switches controllers. If the priority of the grabber is higher than that of the controller, the control of the camera is immediately given to the grabber; if the priority of the grabber is the same as that of the controller, or lower than that of the controller, the original controller is maintained unchanged and the grabber is added to the queue.

[0016] Furthermore, in S200, in the action of "checking the control status, controller and locking time of the current camera", check whether the control status is operated by someone or not, check the user identity information, authority information and priority information of the controller, and check the remaining time of the locking time.

[0017] Furthermore, in S200 and S300, when granting the snatcher the right to use, the following steps are included:

[0018] First, let the snatcher set the lock time;

[0019] Then, a countdown starts according to the snatcher's lock time, and at the same time the snatcher is given control, turning him into a controller.

[0020] Furthermore, the lock time is set to an upper limit of 5 minutes.

[0021] Furthermore, in S300, the queue is partitioned according to priority classification, and the higher priority grabber queue is always located before the lower priority grabber queue, and multiple grabbers of the same priority are arranged from early to late according to the time of initiating the grab right instruction.

[0022] Furthermore, in S300, when the previous controller ends the control, an inquiry of "whether to take control" is automatically initiated to the front grabber in the queue, and a countdown is started. If the grabber confirms to take control during the countdown, the process of granting the grabber the right to use is started; if the grabber gives up the control or the grabber does not respond during the countdown, an inquiry is initiated to the next grabber in the matching queue.

[0023] Furthermore, the conditions for the previous controller to end control are:

[0024] The previous controller voluntarily gave up the right to use;

[0025] Or the lockout period expires.

[0026] A storage medium stores a computer program, which implements the above-mentioned method for regulating camera control priority when executed by a processor.

[0027] A computer device includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. The processor executes the program to implement the above-mentioned method for adjusting the priority of camera control.

[0028] Beneficial effects of the invention: The system and method for controlling camera control priority of the invention significantly improve the efficiency and fairness of camera control in a multi-user environment through a carefully designed modular structure. The core advantage of the system lies in its user priority configuration module, which clearly assigns a priority to each user, ensuring orderliness during resource competition. The application of AOP technology makes request interception and processing more efficient, while enhancing the security and response speed of the system.

[0029] The introduction of the locking mechanism module, through intelligent countdown management, not only guarantees the control time of the current controller, but also provides a fair waiting period for other users, effectively avoiding long-term occupation of resources. The priority determination module makes accurate control rights allocation decisions based on user priority and locking time, further ensuring the fairness of the system.

[0030] The dynamic management function of the queue module optimizes the waiting queue by considering both priority and time sequence, making the transfer of control more reasonable. The implementation of the automatic inquiry mechanism reduces the user's waiting time and improves the efficiency of the transfer of control.

[0031] In addition, the flexibility of the operation and the wide application of the technology of the method of the present invention make it not only suitable for specific monitoring or conference scenarios, but also can be extended to a wider range of multi-user device control fields. Whether implemented through storage media or computer devices, the present application provides a flexible technical solution to adapt to different hardware and software environments, thereby significantly improving the efficiency and fairness in multi-user control scenarios while ensuring monitoring effects and system stability.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1 As shown, a system for controlling priority of camera control includes a user priority configuration module, an AOP request interception module, a locking mechanism module, a priority determination module and a queuing module. The user priority configuration module, the AOP request interception module and the priority determination module are connected in sequence, the priority determination module and the queuing module are bidirectionally connected, and the locking mechanism module is connected to the AOP request interception module and the priority determination module at the same time, wherein,

[0035] User priority configuration module, used to assign camera control priority when creating a user, and the priority information is stored in the system;

[0036] AOP request interception module, used to intercept control requests on the camera control interface, check the current camera status, controller and lock time;

[0037] The locking mechanism module is used to record the current camera controller and the locking time, manage the countdown of the locking time, and thus determine whether to terminate the current controller's right of use;

[0038] The priority determination module is used to determine whether the user has the authority to seize control and make decisions based on the user priority and lock time;

[0039] The queuing module is used to queue the grabbers according to the user priority and grabbing sequence, and automatically initiate a "whether to control" query to the grabber at the front of the queue when the controller is missing.

[0040] Specifically, the present invention realizes efficient and orderly management of camera control in a multi-user environment by constructing a comprehensive camera control priority control system. The system allocates control priority when a user creates an account through a user priority configuration module, ensuring the clarity and rationality of user permissions. The AOP request interception module is responsible for intercepting and checking control requests on the camera control interface, improving the security and response speed of request processing. The locking mechanism module effectively manages the duration of control rights by recording the controller and the locking time, preventing unreasonable occupation of resources. The priority determination module makes a decision on whether to grant control rights based on the user's priority and locking time, ensuring the fairness of control rights allocation. The queuing queue module further optimizes the management of waiting users, queues users by priority and request timing, and automatically asks users in the queue whether they are willing to take over control rights at an appropriate time, thereby improving the interactivity of the system and user satisfaction. Overall, this system not only improves the flexibility and control efficiency of camera control, but also enhances the fairness and transparency in a multi-user operation environment, providing users with a more stable and reliable control experience.

[0041] A method for controlling camera control priority, based on the above-mentioned system for controlling camera control priority, the method for controlling camera control priority comprises the following steps:

[0042] S100, when a user creates an account in the system, the corresponding camera control priority is assigned according to the user's identity and authority and the priority information is stored for subsequent use in determining the control authority;

[0043] S200, using AOP technology, intercepting the control request when the snatcher sends the control request, and checking whether the current camera has a controller, if not, granting the snatcher the right to use; otherwise, checking the control state, controller and locking time of the current camera, and executing S300;

[0044] S300, determining whether the current camera switches controllers. If the priority of the grabber is higher than that of the controller, the control of the camera is immediately given to the grabber; if the priority of the grabber is the same as that of the controller, or lower than that of the controller, the original controller is maintained unchanged and the grabber is added to the queue.

[0045] Specifically, the camera control priority control method proposed in the present invention realizes accurate and efficient management of camera control rights. In the stage of user account creation (S100), the system assigns corresponding camera control priorities according to the user's identity and authority, and stores this information for subsequent use, which lays the foundation for subsequent authority determination. When the user tries to control the camera (S200), AOP technology is used to intercept the control request. This step not only ensures the timeliness of request processing, but also enhances the security of the system. The system then checks whether there is a controller at present. If not, the grabber is directly granted the right to use, thereby avoiding unnecessary waiting. If there is already a controller, the system enters step S300, and decides whether to switch control rights based on the comparison of the grabber's priority with the current controller. This decision-making process reflects the intelligence and fairness of the system. If the grabber's priority is higher, the control right is obtained immediately; if the priority is the same or lower, it is added to the queue and waits for subsequent control opportunities. The introduction of the queue enables all users to have the opportunity to wait and obtain control rights fairly, further improving the user experience and resource utilization efficiency of the system. Overall, this method optimizes the camera control process in a multi-user environment through intelligent permission management and queuing mechanism, ensuring the rational allocation and efficient transfer of control rights.

[0046] Furthermore, in S200, in the action of "checking the control status, controller and locking time of the current camera", check whether the control status is operated by someone or not, check the user identity information, authority information and priority information of the controller, and check the remaining time of the locking time.

[0047] Specifically, the inspection action further refined in S200 involves the following aspects:

[0048] (1) Checking the control status: The system first determines whether the camera is currently in a state of manned or unmanned operation. If the camera is unmanned, the system can directly grant control to the requester, thereby speeding up the response;

[0049] (2) Check the controller information: If the camera already has a controller, the system will check the controller's user identity information, authority information, and priority information. This information helps the system understand the current controller's rights scope and priority level, and provides necessary data support for subsequent authority determination;

[0050] (3) Check lock time: The system also checks whether the time for the current controller to lock the camera has expired. If the lock time is about to end or has ended, the system can prepare to transfer control to the next user in the queue or re-evaluate the allocation of control based on priority.

[0051] Through the above detailed checks, the system can more intelligently handle camera control requests, ensuring that the distribution of control rights is fair and efficient. This approach not only improves the user experience by reducing user waiting time and improving the transparency of operations, but also enhances the stability and security of the system by ensuring that only the right users can get control rights at the right time.

[0052] Furthermore, in S200 and S300, when granting the snatcher the right to use, the following steps are included:

[0053] First, let the snatcher set the lock time;

[0054] Then, a countdown starts according to the snatcher's lock time, and at the same time the snatcher is given control, turning him into a controller.

[0055] Specifically, in steps S200 and S300, when the system decides to grant the snatcher the right to use, the specific steps are as follows:

[0056] (1) Setting the lock time: First, the system requires the snatcher to set a lock time, allowing the user to choose an appropriate control duration according to his or her needs, thereby ensuring that the user can use the camera in a targeted manner, while also reserving usage opportunities for other waiting users.

[0057] (2) Countdown and granting of control rights: After the lock time is set, the system immediately starts the countdown and grants control rights to the snatcher at the same time, thus ensuring a seamless transfer of control rights, reducing delays or interruptions caused by authority switching, and improving the user experience.

[0058] (3) Transformation into controller: With the granting of control rights, the robber officially becomes the current controller and can start operating the camera, conducting surveillance or other related activities. At the same time, the system will record this change, update the information of the current controller, and start managing the countdown of the lock time.

[0059] Through this process, the system not only ensures the reasonable allocation of control rights, but also improves the efficiency and fairness of resource utilization through the setting of lock time and countdown mechanism. The method of the present invention allows users to control cameras according to their own needs and plans, while ensuring that other users also have a fair chance to use the equipment. In addition, this flexible control right management mechanism also helps to reduce the waste of resources and improve the operating efficiency of the entire system.

[0060] Furthermore, the lock time is set to an upper limit of 5 minutes.

[0061] Specifically, by setting the upper limit of the lock time to 5 minutes, a single user is effectively prevented from occupying the camera resources for a long time, thus improving resource utilization and fairness. This measure ensures that all users have the opportunity to use the camera within a reasonable time, reduces waiting time, and provides flexibility for users to complete tasks. In addition, the fixed lock time upper limit simplifies system management and facilitates countdown execution and reallocation of control rights, thus achieving a good balance between ensuring user needs and system control, and improving the efficiency and user satisfaction of the entire camera control priority control system.

[0062] Furthermore, in S300, the queue is partitioned according to priority classification, and the higher priority grabber queue is always located before the lower priority grabber queue, and multiple grabbers of the same priority are arranged from early to late according to the time of initiating the grab right instruction.

[0063] Specifically, in S300, the optimized management of the queue further enhances the efficiency and fairness of the camera control priority control method. Specifically, the queue is partitioned according to the user priority, ensuring that the requests of high-priority users are responded to faster. This partitioning strategy makes the high-priority user queue always ahead of the low-priority user queue, so that it has priority to obtain control. For users with the same priority, the system arranges them according to the time order of their control requests, first come first served, ensuring time fairness. This method not only improves the satisfaction of high-priority users, but also encourages all users to comply with the system rules, because they know that their waiting is meaningful. In addition, this meticulous queuing mechanism also helps to reduce conflicts and improve the transparency of the system, because each user can clearly understand his position in the queue. In general, this queue management based on priority and time order provides a more reasonable and user-friendly operating environment for the camera control priority control method.

[0064] Here is a specific example. There are three predators A, B, and C in the queue. Their priorities are 100, 50, and 100 respectively. The time nodes for initiating control applications are 12:00, 12:01, and 12:02 respectively. If no one cancels the control application, the order of control transfer is A, C, and B.

[0065] Furthermore, in S300, when the previous controller ends the control, an inquiry of "whether to take control" is automatically initiated to the front grabber in the queue, and a countdown is started. If the grabber confirms to take control during the countdown, the process of granting the grabber the right to use is started (the grabber is asked to set a lock time...); if the grabber gives up the control or the grabber has no response during the countdown, an inquiry is initiated to the next grabber in the matching queue.

[0066] Specifically, in step S300, the system further optimizes the distribution process of camera control rights through an automatic inquiry mechanism. When the previous controller ends control, the system immediately starts a countdown and automatically asks the first person in the queue whether to take control. This mechanism ensures the rapid and effective transfer of control rights and reduces the idle period of control rights.

[0067] (1) If the snatcher confirms control during the countdown, the system quickly starts the process of granting the snatcher the right to use the camera, ensuring the continuity and real-time nature of camera control.

[0068] (2) If the snatcher gives up control or does not respond within the specified time, the system will automatically query the next snatcher in line, ensuring that every user has an equal opportunity to gain control.

[0069] (3) Through the countdown and automatic inquiry mechanism, the system reduces the time other users have to wait to control the camera, thus improving the overall user experience.

[0070] (4) This mechanism encourages users to stay focused while queuing, as they may need to respond to the system’s inquiries at any time, thereby improving the overall operating efficiency of the system.

[0071] (5) This interaction between the system and the user enhances the user's sense of participation and control over the system, making the user more actively interact with the system.

[0072] (6) By ensuring that control is transferred promptly to users who are willing and prepared to exercise control, the system avoids wasting resources due to user unresponsiveness.

[0073] Furthermore, the conditions for the previous controller to end control are:

[0074] The previous controller voluntarily gave up the right to use;

[0075] Or the lockout period expires.

[0076] Specifically, in step S300, the conditions for the previous controller to end control are stipulated to be the active abandonment of the right to use or the expiration of the lock time, which further clarifies the triggering conditions for the transfer of control rights. Specifically:

[0077] (1) After completing the monitoring or operation task, the controller can actively release the camera control right, which not only reflects the user's autonomy, but also provides other waiting users with the opportunity to use the camera.

[0078] (2) Introduce a lock time mechanism to ensure that the controller must release control rights after a certain period of time, regardless of whether the task is completed. This helps prevent the controller from occupying resources for a long time and ensures fair allocation of resources.

[0079] (3) Clarify the conditions for ending control so that all users can clearly understand when they can expect to regain control, increasing the transparency of the system and user trust.

[0080] (4) By limiting the control time, users are encouraged to use resources efficiently while ensuring that other users can get the opportunity to use the camera in a timely manner, thereby improving the overall utilization rate of the camera.

[0081] (5) Clear control end conditions help reduce conflicts between users because each user can anticipate when it is his or her turn to control the camera.

[0082] A storage medium stores a computer program, which implements the above-mentioned method for regulating camera control priority when executed by a processor.

[0083] Specifically, the storage medium provided by the present invention is embedded with a carefully designed computer program. Once executed on a processor, it can automatically implement a camera control priority control method to ensure efficient and orderly allocation and use of camera resources in a multi-user environment. This storage medium is easy to deploy, improves the efficiency and reliability of the control process, and at the same time, through the scalability and compatibility of the program, ensures the long-term applicability of the system and the applicability of a wide range of devices. In addition, its built-in security features and maintenance functions further enhance the stability and manageability of the system, providing users with a comprehensive and efficient solution.

[0084] A computer device includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. The processor executes the program to implement the above-mentioned method for adjusting the priority of camera control.

[0085] Specifically, the computer device proposed in the present invention provides users with a highly integrated and automated solution to achieve effective regulation of camera control priority through its built-in memory, high-performance processor and computer program developed for this purpose. The device not only ensures the convenience of operation and high efficiency of management, but also ensures the stability and security of the system through its design, while supporting future technology upgrades and functional expansions, greatly improving the utilization efficiency of camera resources and the user's operating experience in a multi-user environment.

The user priority configuration module ensures the orderliness of resource competition, and the AOP technology improves the efficiency of request processing and system security. The locking mechanism module balances the controller's usage rights and the fairness of waiting users through countdown management, while the priority determination module ensures the fairness of control rights allocation. The dynamic management and automatic inquiry mechanism of the queuing queue module further optimize the flow of control rights and reduce user waiting time. This method is not only suitable for monitoring or conference scenarios, but can also be extended to a wider range of equipment control fields, providing a flexible technical solution that adapts to a variety of hardware and software environments, thereby significantly improving the efficiency and fairness of multi-user control scenarios while ensuring monitoring effects and system stability.
