[0033] Please see Figure 1 This is a schematic block diagram illustrating the application environment of the multi-camera control method according to an embodiment of this application. The application environment of the multi-camera control method according to an embodiment of this application includes a camera remote control device 110, a plurality of cameras 120, and a multi-camera control device 130. The plurality of cameras 120 are respectively connected to the camera remote control device 110 and the multi-camera control device 130. The camera remote control device 110 is used to send first camera remote control data. The plurality of cameras 120 respectively transmit the collected first camera remote control data to the multi-camera control device 130. The multi-camera control device controls the action of the target camera according to the plurality of first camera remote control data and the time of receiving the plurality of first camera remote control data.

[0034] The multiple cameras 120 generally have basic functions such as video recording / transmission and still image capture. After the cameras capture images through their lenses, the photosensitive component circuit and control component inside the cameras process the images and convert them into digital signals that can be recognized by the multi-camera control device 130. Then, the signals are input to the multi-camera control device 130 for image reconstruction via a parallel port or USB connection. The multiple cameras 120 can be identical cameras or different cameras; this application does not impose any restrictions.

[0035] The camera remote control device 110 establishes a wireless connection with several cameras 120. Optionally, the wireless method can be various types such as infrared remote control or Bluetooth remote control, so that the several cameras 120 can receive the camera remote control signal emitted by the camera remote control device 110. Specifically, the camera remote control device 110 can be an infrared remote control, a remote control with Bluetooth communication function, etc.

[0036] The multi-camera control device 130 can be implemented through software and / or hardware. The multi-camera control device 130 can consist of two or more physical entities, or it can consist of a single physical entity. From a hardware perspective, the hardware referred to by the multi-camera control device 130 is essentially a computer device with capabilities equivalent to a personal computer. It is a hardware device with the necessary components revealed by the von Neumann architecture, such as a central processing unit (including an arithmetic logic unit and a control unit), memory, input devices, and output devices. The computer program is stored in the memory, and the central processing unit calls the computer program stored in the memory to run it, execute the instructions in the computer program, and interact with the input / output devices to complete specific functions.

[0037] Optionally, the multi-camera control device 130 may include a display 140, meaning the display 140 is part of the multi-camera control device 130; or the multi-camera control device 130 may also be connected to the display 140, meaning the display 140 exists independently of the components of the multi-camera control device 130. The display 140 is used to receive instructions from the multi-camera control device 130 to display images captured by the cameras, or information such as the working status of each camera.

[0038] It should be noted that the multi-camera control method of this application can be applied to conference and education scenarios. This application takes a conference scenario as an example to illustrate the multi-camera control method of this application. Specifically, several cameras 120 are arranged in the conference room, and the several cameras 120 are respectively connected to the camera remote control device 110 and the multi-camera control device 130; the identification and control of one or more cameras in the conference room can be realized through the camera remote control device 110 and the multi-camera control device 130.

[0039] Example 1

[0040] The following will be combined with the appendix Figures 2 to 6 This application provides a detailed description of the multi-camera control method provided in its embodiments.

[0041] Please see Figure 2 This is a flowchart illustrating a multi-camera control method according to an embodiment of this application; the multi-camera control method provided in this embodiment includes the following steps:

[0042] Step S101: Receive several first camera remote control data transmitted by several cameras within a preset time period and obtain the time of receiving several first camera remote control data.

[0043] When a remote control event occurs on the camera remote control device, such as when a user presses a button, the camera remote control device will generate a corresponding camera remote control command, thereby broadcasting first camera remote control data. Several cameras that have established a wireless connection with the camera remote control device can acquire this first camera remote control data within their wireless reception range. Subsequently, the first camera remote control data collected by the several cameras will be forwarded to the multi-camera control device.

[0044] It is understandable that the first camera remote control data collected by several cameras is the same first camera remote control data. This first camera remote control data corresponds to the remote control event and is used to control the action of one or more cameras.

[0045] Understandably, when several cameras forward the first camera remote control data they collect to the multi-camera control device, the multi-camera remote control device will receive several first camera remote control data within a preset time. At this time, the multi-camera remote control device can record the time of receiving several first camera remote control data.

[0046] Step S102: Based on the time difference of receiving several first camera remote control data and several first camera remote control data, obtain a target camera remote control data corresponding to a remote control event; wherein, the target camera remote control data is used to indicate sending a target remote control command to the target camera.

[0047] Clearly, when several cameras forward the first camera remote control data they collect to the multi-camera control device, within a preset time, the several first camera remote control data obtained by the multi-remote control device may correspond to one remote control event or multiple remote control events. Therefore, by distinguishing and obtaining one target camera remote control data corresponding to one remote control event based on the time difference of receiving several first camera remote control data and the several first camera remote control data, the control of the target camera can be realized.

[0048] The target remote control command can be any command that controls the camera's actions, such as commands to turn the camera on, turn the camera off, adjust the camera's orientation, take a picture, or record video.

[0049] Step S103: Send the target remote control command to the target camera corresponding to the target camera identifier.

[0050] This application embodiment receives several first camera remote control data transmitted by several cameras within a preset time period and obtains the time of receiving the several first camera remote control data; based on the time difference of receiving the several first camera remote control data and the several first camera remote control data, it obtains a target camera remote control data corresponding to a remote control event; wherein, the target camera remote control data is used to indicate sending a target remote control command to a target camera; the target remote control command is sent to the target camera, so that each camera can obtain the first camera remote control data, thereby conveniently and quickly realizing the control of any camera and reducing costs.

[0051] In one embodiment, before the steps of receiving several first camera remote control data transmitted by several cameras within a preset time and obtaining the time of receiving the several first camera remote control data in step S101, the following steps are further included, namely, step S100:

[0052] Step S100: When a camera is detected to be connected, obtain the device information of the camera, configure a camera number for the camera, and establish a mapping relationship between the device information of the camera and the camera number; wherein, the camera number corresponds to one or more pieces of device information.

[0053] Device information, including the camera's IP address, MAC address, or the socket of the communication channel connected to the camera, allows multi-camera control devices to identify one or more of the camera's information. When the device information includes multiple pieces of information, it allows the system to obtain the necessary information, such as updating camera mapping information or retrieving camera-related information, using any of the aforementioned pieces of information.

[0054] The camera number is a serial number assigned to the camera based on actual needs, allowing users to easily identify the camera. Optionally, cameras can be numbered sequentially according to the order in which they were connected, such as 1, 2, 3, etc.

[0055] In one application scenario, because each camera has a different location and function, each camera number uniquely corresponds to one device information, thus enabling control of a single camera based on its number. In another application scenario, cameras can be grouped together based on their orientation or function. For example, turning on the camera on the left or the camera used for monitoring teaching can be done by assigning multiple device information to the same camera number, thereby enabling control of several cameras with the same camera number.

[0056] The step of sending the target remote control command to the target camera in step S103 includes the following steps S1031-S1033:

[0057] Step S1031: Obtain the target camera number.

[0058] Step S1032: Obtain the device information of the target camera corresponding to the target camera number based on the mapping relationship between the device information of the camera and the camera number.

[0059] Step S1033: Based on the device information of the target camera, send the target remote control command to the target camera.

[0060] This application establishes a mapping relationship between camera device information and camera number, enabling interaction between the user and the multi-camera control device and the camera, thereby allowing the multi-camera control device to control the corresponding camera based on the camera number input by the user.

[0061] Optionally, the step of obtaining the target camera number in step S1031 includes: obtaining the default target camera number. In one application scenario, a multi-camera device has a default target camera number. When remote control data for a target camera is received, the corresponding target camera is controlled according to the target camera number. It is understood that users can change the default target camera number in the multi-camera device according to actual needs, thereby achieving control of the desired target camera.

[0062] Optionally, the target camera remote control data includes the target camera number; the step of obtaining the target camera number in step S1031 includes: obtaining the target camera number from the target camera remote control data. In one application scenario, the camera remote control device sends a remote control command and simultaneously sends the target camera number to be controlled, thereby allowing direct specification of the corresponding target camera in the camera remote control device to control the target camera.

[0063] Please see Figure 3In one embodiment, the camera's device information further includes the camera's MAC address; the step S100, which involves obtaining the camera's device information and configuring a camera number for the camera when its access is detected, and establishing a mapping relationship between the camera's device information and the camera number, includes steps S1001-S1003 as follows:

[0064] S1001: When a camera is detected to be connected, obtain the MAC addresses of all currently connected cameras, and determine whether a corresponding mapping relationship has been established between the currently connected cameras based on the MAC addresses.

[0065] Optionally, the MAC addresses of all currently connected cameras can be obtained via multicast.

[0066] S1002: If the camera does not have a corresponding mapping relationship, obtain the current device connection information of the camera, configure a camera number for the camera, and establish a mapping relationship between the camera MAC address, the device connection information and the camera number.

[0067] S1003: If the camera has already established a corresponding mapping relationship, obtain the current device connection information of the camera and the device connection information in the mapping relationship; when the current device connection information of the camera is different from the device connection information in the mapping relationship, replace the device connection information in the mapping relationship with the current device connection information, and update the mapping relationship corresponding to the MAC address of the camera.

[0068] Optionally, the camera can be hot-swapped to the multi-camera control device. Specifically, the multi-camera control device may include several USB ports; the camera may include a UVC (USB Video Class) port; the multi-camera control device can be hot-swapped to several cameras through several USB ports and several UVC ports; that is, the camera can be plugged into the running multi-camera control device or unplugged from the USB port of the running multi-camera control device.

[0069] In this scenario, different USB ports use the same socket; the same USB port uses the same socket. In one application scenario, for the same camera, it might be plugged into the first USB port, unplugged, and then plugged back into the first USB port. Although multiple camera devices can detect two camera connections, the actual device information obtained, such as the camera's IP address, MAC address, or the socket of the communication channel connected to the camera, is the same. In another application scenario, for the same camera, it might be plugged into the first USB port, unplugged, and then plugged into the second USB port. In this case, multiple camera devices can detect two camera connections, but the camera's MAC address is the same; only the camera's IP address and the socket of the communication channel connected to the camera are different. Therefore, the unique camera MAC address is used to determine whether a mapping relationship needs to be established and updated, thereby achieving accurate control of the camera.

[0070] It is understood that when the current device connection information of the camera is the same as the device connection information in the mapping relationship, the mapping relationship remains unchanged.

[0071] In one embodiment, step S101, which involves receiving several sets of first camera remote control data transmitted by several cameras within a preset time period and obtaining the time of receiving the several sets of first camera remote control data, includes:

[0072] Step S1011: Obtain target transmission device information.

[0073] The target transmission device information may include the camera's IP address, MAC address, or the socket of the communication channel connected to the camera, which can enable the multi-camera control device to identify one or more of the camera's information.

[0074] Step S1012: Receive several first camera remote control data transmitted by several cameras corresponding to the target transmission device information within a preset time, and obtain the time of receiving several first camera remote control data.

[0075] In one application scenario, the user's location is relatively fixed, such as in a conference room. Typically, the presenter or other participants walk to the front to give a presentation. In this case, it is only necessary to acquire the first camera remote control data captured by the camera at the front of the conference room. This first camera remote control data can then be directly used as the target remote control data to control the target camera. In this situation, the first camera remote control data transmitted by other cameras is obviously redundant. Therefore, target transmission device information can be set, so that only the first camera remote control data transmitted by the camera corresponding to the target transmission device information is received to determine the target remote control data. This reduces the acquisition and identification of first camera remote control data and improves the efficiency of camera identification and control.

[0076] Please see Figure 4 In one embodiment, step S102, which describes obtaining a target camera remote control data corresponding to a remote control event based on the time difference of receiving a plurality of first camera remote control data and the plurality of first camera remote control data, includes the following steps S10211-S10212:

[0077] S10211: Calculate the time difference between receiving a plurality of first camera remote control data, and obtain a plurality of second camera remote control data whose time difference is within a preset time threshold.

[0078] Optionally, a number of first camera remote control data are received sequentially within a preset time period, and the time difference between the received number of first camera remote control data is calculated one by one. Then, it is determined whether the time difference is within a preset time threshold, and the number of first camera remote control data whose time difference is within the preset time threshold is used as a number of second camera remote control data.

[0079] S10212: Merge several second camera remote control data into one target camera remote control data.

[0080] In one application scenario, when a user needs to control one or more target cameras, the target camera may be too far away to receive the first remote control data sent by the camera remote control device. In this case, control of the target camera can be achieved by acquiring several first remote control data sets collected by several cameras near the user. Specifically, since several cameras collect several first remote control data sets for a single remote control event, and these sets arrive at the multi-camera control device at roughly the same time, several second remote control data sets with time differences within a preset time threshold can be merged into a single target remote control data set. This target remote control data can then be used to control the target camera.

[0081] This application embodiment calculates the time difference between receiving several first camera remote control data and obtains several second camera remote control data whose time difference is within a preset time threshold. The several second camera remote control data are then merged into one target camera remote control data. After receiving several first camera remote control data transmitted from several cameras, the target remote control data can be obtained accurately and quickly, thereby realizing the control of the target camera.

[0082] Please see Figure 5 In another embodiment, step S102, which describes obtaining a target camera remote control data corresponding to a remote control event based on the time difference of receiving a plurality of first camera remote control data and the plurality of first camera remote control data, includes the following steps S10221-S10223:

[0083] S10221: Calculate the time difference between receiving a plurality of first camera remote control data, and obtain a plurality of second camera remote control data whose time difference is within a preset time threshold.

[0084] Optionally, a number of first camera remote control data are received sequentially within a preset time period, and the time difference between the received number of first camera remote control data is calculated one by one. Then, it is determined whether the time difference is within a preset time threshold, and the number of first camera remote control data whose time difference is within the preset time threshold is used as a number of second camera remote control data.

[0085] S10222: Obtain device information of the camera that transmits the second camera remote control data.

[0086] The device information includes the camera's IP address, MAC address, or socket of the communication channel connected to the camera, which allows the multi-camera control device to identify one or more of the camera's information.

[0087] An IP address (Internet Protocol Address) is a logical address provided by the IP protocol, which assigns a unique address to every network and every host on the Internet.

[0088] The MAC address (Media Access Control Address), also known as the physical address or hardware address, is burned into the EPROM (a type of flash memory chip that can usually be erased and rewritten by a program) of the network interface card (NIC) by the network equipment manufacturer during production. It is used to uniquely identify the device.

[0089] A socket is one end of inter-process communication on a network, providing a mechanism for application-layer processes to exchange data using network protocols. In terms of its position, a socket connects to the application process above and the network protocol stack below. It is the interface through which applications communicate via network protocols, the interface through which applications interact with the network protocol root, and can also be seen as the endpoint in the communication connection between two network applications.

[0090] In this embodiment, the device information of the camera transmitting the second camera remote control data obtained in step S10222 is the socket of the communication channel corresponding to the camera. Specifically, several cameras communicate with a multi-camera control device through their respective communication channels, and a thread is set for each communication channel to monitor the operation of each communication channel. When the first camera remote control data is received on the communication channel, the socket of the corresponding communication channel can be obtained through the thread. At the same time, by calculating the time difference of receiving several first camera remote control data, several second camera remote control data with the time difference within a preset time threshold are obtained, thereby obtaining the device information of the camera transmitting the second camera remote control data.

[0091] S10223: Several second camera remote control data with the same device information of the camera transmitting the second camera remote control data are respectively used as target camera remote control data, and several second camera remote control data with different device information of the camera transmitting the first camera remote control data are merged into one target camera remote control data.

[0092] In one application scenario, within a preset time period, the camera remote control device may experience multiple button presses, generating multiple remote control events and thus multiple sets of first camera remote control data. In this case, the same camera may continuously transmit multiple sets of first camera remote control data within the preset time. Therefore, among several sets of second camera remote control data, it is necessary to determine which sets are transmitted from the same camera. For multiple sets of second camera remote control data transmitted from the same camera, each set needs to be used as a separate target remote control data. Since each camera is connected to a different socket, several sets of second camera remote control data transmitted from cameras connected to the same socket are used as separate target remote control data, while several sets of second camera remote control data transmitted from cameras connected to different sockets are merged into a single target remote control data.

[0093] In this embodiment of the application, among several second camera remote control data that have a time difference within a preset time threshold, the device information of the camera transmitting the second camera remote control data is combined to further identify the target camera remote control data, which can further improve the accuracy of identifying the target camera remote control data.

[0094] The following is in conjunction with the appendix Figure 6 A detailed explanation of the multi-camera control method.

[0095] like Figure 6 As shown, when the multi-camera control device detects a camera connection, it obtains the MAC addresses of all currently connected cameras via multicast. Based on the MAC addresses, it determines whether a corresponding mapping relationship has been established between the currently connected cameras. If no corresponding mapping relationship has been established, it obtains the current IP address of the camera and the corresponding connection socket, configures a camera number for the camera, and establishes a mapping relationship between the camera's MAC address, IP address, corresponding connection socket, and camera number.

[0096] When a remote control event occurs on the camera remote control device, such as when a user presses one of the control buttons, the camera remote control device generates a corresponding camera remote control command, causing it to broadcast first camera remote control data. Several cameras wirelessly connected to the camera remote control device acquire this first camera remote control data within their wireless reception range. These cameras then forward their respective first camera remote control data to a multi-camera control device. The multi-camera control device receives several first camera remote control data packets from the cameras and obtains the corresponding socket for each camera and the time the data was received through a thread. Next, the multi-camera control device imports the first camera remote control data packets, the corresponding sockets for each camera, and the time the data was received into a remote control filter to obtain target camera remote control data corresponding to a remote control event. Finally, the target remote control command is obtained based on the target camera remote control data. Meanwhile, the multi-camera control device obtains the default target camera number, and based on the camera's MAC address, IP address, and the mapping relationship between the corresponding connection socket and the camera number, obtains the socket corresponding to the target camera number. Then, it sends the target remote control command to the target camera through the socket corresponding to the target camera number, thereby realizing the control of the target camera.
