Example 1

The following describes in detail the multi-camera control method provided in the embodiment of the present application with reference to fig. 2 to 6.

Referring to fig. 2, a flowchart of a multi-camera control method according to an embodiment of the present application is shown; the multi-camera control method provided by the embodiment of the application comprises the following steps:

Step S101: and receiving a plurality of first shooting remote control data transmitted by a plurality of cameras respectively in preset time and acquiring time for receiving a plurality of first shooting remote control data.

When a remote control event is generated on the camera remote control device, for example, when a user presses a key, the camera remote control device generates a corresponding camera remote control instruction, so that the camera remote control device broadcasts and sends out first camera remote control data; and the cameras which are in wireless connection with the camera remote control equipment can acquire the first camera remote control data in the wireless receiving range. And then, the plurality of cameras transmit the first camera remote control data acquired respectively to the multi-camera control equipment.

It can be understood that the first camera remote control data respectively collected by the plurality of cameras is the same first camera remote control data, and the first camera remote control data corresponds to a remote control event and is used for controlling one or more cameras to act.

It can be understood that when the plurality of cameras transmit the first camera remote control data acquired respectively to the multi-camera control device, the multi-camera remote control device receives the plurality of first camera remote control data within a preset time, and at this time, the multi-camera remote control device can record the time of receiving the plurality of first camera remote control data respectively.

Step S102: obtaining target shooting remote control data corresponding to a remote control event according to the time difference of receiving a plurality of first shooting remote control data and a plurality of first shooting remote control data; the target camera remote control data are used for indicating to send a target remote control instruction to the target camera.

Obviously, when the plurality of cameras transmit the first shooting remote control data acquired respectively to the multi-camera control device, in a preset time, the plurality of first shooting remote control data acquired by the multi-remote control device may correspond to one remote control event or may correspond to a plurality of remote control events, so that one target shooting remote control data corresponding to one remote control event is obtained by distinguishing according to the time difference of receiving the plurality of first shooting remote control data and the plurality of first shooting remote control data, so as to realize control of the target cameras.

The target remote control instruction can be any instruction for controlling the action of the camera, such as an instruction for controlling the opening of the camera, an instruction for controlling the closing of the camera, an instruction for adjusting the steering of the camera, an instruction for controlling the photographing of the camera, an instruction for controlling the video of the camera, and the like.

Step S103: and sending the target remote control instruction to a target camera corresponding to the target camera identification.

According to the embodiment of the application, the first camera remote control data transmitted by the cameras respectively in the preset time are received, and the time for receiving the first camera remote control data is acquired; obtaining target camera remote control data corresponding to a remote control event according to the time difference of receiving a plurality of first camera remote control data and a plurality of first camera remote control data; the target camera shooting remote control data are used for indicating to send a target remote control instruction to the target camera shooting head; and the target remote control instruction is sent to the target cameras, so that each camera can obtain the first shooting remote control data, and further, the control of any one camera can be conveniently and quickly realized, and the cost is reduced.

In one embodiment, before the step of receiving the plurality of first image capturing remote control data respectively transmitted by the plurality of cameras within the preset time and the step of obtaining the time of receiving the plurality of first image capturing remote control data in step S101, the method further includes the following steps:

Step S100: when monitoring that a camera is accessed, acquiring equipment information of the camera, configuring a camera number for the camera, and establishing a mapping relation between the equipment information of the camera and the camera number; wherein the camera number corresponds to one or more of the device information.

The device information includes one or more of information of the camera, such as an IP address of the camera, a mac address of the camera, or a socket (socket) of a communication channel correspondingly connected to the camera, which may enable the multi-camera control device to identify the camera. When the device information includes various information, the camera mapping information may be updated or the camera related information may be obtained through any of the above information.

The camera numbers are serial numbers which are set for the camera according to actual needs, so that a user can intuitively identify the camera. Optionally, the camera configuration may be numbered sequentially according to the time sequence of the access of the camera, such as 1,2,3, etc.

In an application scene, because the position and the action of each camera are different, the camera number uniquely corresponds to one piece of equipment information, and therefore the control of the unique camera is realized according to the camera number. In another application scenario, the cameras can be classified into the same group according to the direction or action, for example, the left camera is started, the monitoring teaching camera is started, and the like, and the camera numbers can be corresponding to a plurality of pieces of equipment information, so that control of a plurality of cameras with the same camera number is realized.

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

step S1031: and obtaining the number of the target camera.

Step S1032: and obtaining the equipment information of the target camera corresponding to the target camera number according to the mapping relation between the equipment information of the camera and the camera number.

Step S1033: and sending the target remote control instruction to the target camera according to the equipment information of the target camera.

According to the method and the device for controlling the camera, the mapping relation between the equipment information of the camera and the camera number is established, interaction between a user and the multi-camera control equipment and interaction between the user and the camera can be achieved, and the multi-camera control equipment can control the corresponding camera according to the camera number input by the user.

Optionally, the step of obtaining the number of the target camera in step S1031 includes: and acquiring a target camera number set by default. In one application scenario, the multi-camera device defaults to a target camera number, and when receiving target image remote control data, the multi-camera device controls a corresponding target camera according to the target camera number. It can be appreciated that the user can change the default target camera number in the multi-camera device according to actual needs, thereby realizing control of the required target cameras.

Optionally, the target camera remote control data includes a target camera number; the step of obtaining the number of the target camera in step S1031 includes: and acquiring a target camera number from the target camera remote control number. In an application scene, the camera remote control equipment sends a remote control instruction and simultaneously sends a target camera number to be controlled, so that a corresponding target camera can be directly designated and controlled in the camera remote control equipment, and the control of the target camera is realized.

Referring to fig. 3, in one embodiment, the device information of the camera further includes a camera mac address; when the camera access is monitored in the step S100, acquiring the equipment information of the camera, configuring a camera number for the camera, and establishing a mapping relationship between the equipment information of the camera and the camera number, wherein the steps S1001-S1003 are as follows:

s1001: when the access of the cameras is monitored, the mac addresses of all cameras which are accessed currently are obtained, and whether the corresponding mapping relation is established among all cameras which are accessed currently is judged according to the mac addresses.

Alternatively, mac addresses of all cameras currently accessed can be obtained through a multicast mode.

S1002: if the camera does not establish a corresponding mapping relation, acquiring current equipment connection information of the camera, configuring a camera number for the camera, and establishing a mapping relation among the camera mac address, the equipment connection information and the camera number.

S1003: if the camera has established a corresponding mapping relation, acquiring current equipment connection information of the camera and the equipment connection information in the mapping relation; when the current equipment connection information of the camera is different from the equipment connection information in the mapping relation, replacing the equipment connection information in the mapping relation with the current equipment connection information, and updating the mapping relation corresponding to the mac address of the camera.

Optionally, the camera may be connected to the multi-camera control device by hot plug, and in particular, the multi-camera control device may include a plurality of USB interfaces; the camera may include a UVC (USB Video Class) interface; the multi-camera control equipment is connected with the cameras in a pluggable manner through the USB interfaces and the UVC interfaces; i.e. the camera can be plugged into the running multi-camera control device or pulled out of the USB interface of the running multi-camera control device.

Wherein, the sockets corresponding to different USB interfaces are the same; the sockets corresponding to the same USB interface are the same. In an application scenario, for the same camera, after the first USB interface is inserted, the same camera may be pulled out and then inserted into the first USB interface, where, although the multi-camera device may monitor the access of the camera twice, the device information of the camera actually obtained is the same as the IP address of the camera, the mac address of the camera, or the socket of the communication channel correspondingly connected to the camera. In another application scenario, for the same camera, after the first USB interface is inserted, the same camera may be pulled out and then inserted into the second USB interface, at this time, the multi-camera device may monitor the access of the camera twice, but the mac addresses of the cameras are the same, but the IP addresses of the cameras are different from the socket of the communication channel correspondingly connected to the cameras, so that whether the mapping relationship needs to be established or not and whether the mapping relationship needs to be updated is judged through the unique mac address of the camera, thereby realizing accurate control of the camera.

It can be 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 is kept unchanged.

In one embodiment of the present invention, in one embodiment, in step S101, the step of receiving a plurality of first image capturing remote control data respectively transmitted by a plurality of cameras within a preset time and obtaining a time for receiving a plurality of first image capturing remote control data includes:

step S1011: and acquiring target transmission equipment information.

The target transmission device information may include one or more of an IP address of the camera, a mac address of the camera, a socket (socket) of a communication channel correspondingly connected to the camera, or the like, which may enable the multi-camera control device to recognize the camera.

Step S1012: receiving a plurality of first shooting remote control data which are respectively transmitted by a plurality of cameras corresponding to target transmission equipment information in preset time, and acquiring time for receiving the plurality of first shooting remote control data.

In an application scene, the position of the user is relatively fixed, for example, in a conference room, a presenter or conference personnel walks to the front to carry out a lecture, at this time, only the first image capturing remote control data collected by one camera in front of the conference room is needed to be obtained, and then the first image capturing remote control data collected by the camera is directly used as target remote control data, so that the control of the target camera is realized, at this time, the first image capturing remote control data transmitted by other cameras are obviously superfluous, therefore, the target transmission equipment information can be set, and only the first image capturing remote control data transmitted by the camera corresponding to the target transmission equipment information is received to determine the target remote control data, so that the acquisition and identification of the first image capturing remote control data are reduced, and the identification and control efficiency of the camera are improved.

Referring to fig. 4, in one embodiment, the step of obtaining, in step S102, target remote control data corresponding to a remote control event according to a time difference of receiving a plurality of first remote control data and a plurality of first remote control data includes steps S10211 to S10212 as follows:

s10211: calculating time differences of receiving a plurality of first shooting remote control data, and obtaining a plurality of second shooting remote control data of which the time differences are within a preset time threshold.

Optionally, the time difference of the received plurality of first image capturing remote control data may be calculated one by one after receiving the plurality of first image capturing remote control data in sequence within a preset time, so as to determine whether the time difference is within a preset time threshold, so that the plurality of first image capturing remote control data with the time difference within the preset time threshold is used as the plurality of second image capturing remote control data.

S10212: and combining a plurality of second camera shooting remote control data into one target camera shooting remote control data.

In an application scene, when a user needs to control one or more than two target cameras, the target cameras cannot receive first image capturing remote control data sent by the image capturing remote control equipment because the positions of the target cameras are far away from the user; at this time, control over the target camera may be achieved by acquiring a plurality of first camera remote control data acquired by a plurality of cameras near the user. Specifically, for a remote control event, the plurality of cameras collect the plurality of first camera remote control data, and when the plurality of first camera remote control data are to be forwarded to the multi-camera control device, the time of the plurality of first camera remote control data reaching the multi-camera device is almost the same, so that the plurality of second camera remote control data which acquire the time difference within a preset time threshold can be combined into one camera remote control data to serve as target camera remote control data, and the target camera is controlled by the target camera remote control data.

According to the method and the device for controlling the target camera, the time difference of receiving the plurality of first camera remote control data is calculated, the plurality of second camera remote control data with the time difference within the preset time threshold are obtained, the plurality of second camera remote control data are combined into the target camera remote control data, and the target remote control data can be accurately and rapidly obtained after the plurality of first camera remote control data transmitted by the plurality of cameras are received, so that the control of the target camera is realized.

Referring to fig. 5, in another embodiment, in step S102, the step of obtaining target remote control data corresponding to a remote control event according to the time difference of receiving a plurality of the first remote control data and a plurality of the first remote control data includes the following steps S10221-S10223:

s10221: calculating time differences of receiving a plurality of first shooting remote control data, and obtaining a plurality of second shooting remote control data of which the time differences are within a preset time threshold.

Optionally, the time difference of the received plurality of first image capturing remote control data may be calculated one by one after receiving the plurality of first image capturing remote control data in sequence within a preset time, so as to determine whether the time difference is within a preset time threshold, so that the plurality of first image capturing remote control data with the time difference within the preset time threshold is used as the plurality of second image capturing remote control data.

S10222: and acquiring equipment information of the camera transmitting the second camera remote control data.

The device information includes one or more of information of the camera, such as an IP address of the camera, a mac address of the camera, or a socket (socket) of a communication channel correspondingly connected to the camera, which may enable the multi-camera control device to identify the camera.

Wherein, the IP address (nternet Protocol Address) refers to an Internet protocol address, and is translated into an Internet protocol address being an IP protocol. The IP address is a unified address format provided by the IP protocol, which assigns a logical address to each network and each host on the internet.

The mac address (Media Access Control Address ) is also called a physical address or a hardware address, and is burned on an EPROM (a flash memory chip, which may be typically erased by a program) of the network card (Network lnterface Card) when produced by a manufacturer of the network device, and is used to uniquely identify the device.

The socket is one end of the communication of the process on the network, and provides a mechanism for the application layer process to exchange data by using the network protocol. In terms of the position, the socket is connected with the application process in an upper mode, the lower network protocol stack is an interface for the application program to communicate through a network protocol, is an interface for the application program to interact with a network protocol root, and can also be regarded as endpoints in respective communication connection when the two network application programs communicate.

In this embodiment of the present application, the device information of the camera that transmits the second remote control data for image capturing, acquired in step S10222, is a socket of a communication channel correspondingly connected to the camera. Specifically, the cameras and the multi-camera control device communicate through respective communication channels, and each communication channel is correspondingly provided with a thread, so that the work of each communication channel is monitored through the thread; when first shooting remote control data are received in a communication channel, a socket corresponding to the communication channel can be obtained through a thread, meanwhile, the time difference of receiving a plurality of first shooting remote control data is calculated, a plurality of second shooting remote control data of which the time difference is within a preset time threshold are obtained, and then equipment information of a camera transmitting the second shooting remote control data is obtained.

S10223: and respectively taking a plurality of second shooting remote control data with the same equipment information of the cameras transmitting the second shooting remote control data as target shooting remote control data, and combining the plurality of second shooting remote control data with different equipment information of the cameras transmitting the first shooting remote control data into one target shooting remote control data.

In an application scenario, there may be multiple key operations on the camera remote control device in a preset time to generate multiple remote control events, so as to generate multiple first camera remote control data, where the same camera may continuously transmit multiple first camera remote control data in the preset time. The socket of each camera is different, so that the plurality of second camera remote control data transmitted by the camera corresponding to the same socket are respectively used as target remote control data, and the plurality of second camera remote control data transmitted by the cameras corresponding to different sockets are combined into one target remote control data.

According to the method and the device for identifying the target shooting remote control data, in the process of obtaining the plurality of second shooting remote control data with the time difference within the preset time threshold, the target shooting remote control data are further identified by combining the equipment information of the cameras for transmitting the second shooting remote control data, and the accuracy of identifying the target shooting remote control data can be further improved.

The following describes the multi-camera control method in detail with reference to fig. 6.

As shown in fig. 6, when the multi-camera control device monitors an event with camera access, acquiring mac addresses of all cameras currently accessed in a multicast mode, and judging whether corresponding mapping relations are established for all cameras currently accessed according to the mac addresses; if the camera does not establish a corresponding mapping relation, acquiring the current IP address of the camera and the socket corresponding to the camera, configuring the camera number for the camera, and establishing the mapping relation of the camera mac address, the IP address of the camera and the socket corresponding to the camera and the camera number.

When a remote control event is generated on the camera remote control device, for example, when a user presses one of the control keys, the camera remote control device generates a corresponding camera remote control instruction, so that the camera remote control device broadcasts and sends out first camera remote control data; and the cameras are in wireless connection with the camera remote control equipment, and the first camera remote control data are acquired in the wireless receiving range of the cameras. The plurality of cameras transmit the first camera remote control data acquired respectively to the multi-camera control equipment, and at the moment, the multi-camera control equipment receives the plurality of first camera remote control data transmitted by the plurality of cameras, and obtains sockets corresponding to the cameras and the time for receiving the first camera remote control data through threads; then, the multi-camera control equipment leads a plurality of first camera remote control data, sockets corresponding to all cameras and time for receiving the first camera remote control data into a remote control filter to obtain target camera remote control data corresponding to a remote control event; and obtaining a target remote control instruction according to the target shooting remote control data. Meanwhile, the multi-camera control equipment acquires a target camera number set by default, acquires a socket corresponding to the target camera number according to the camera mac address, the IP address of the camera and the mapping relation of the socket corresponding to the camera and the camera number, and then sends a target remote control instruction to the target camera through the socket corresponding to the target camera number so as to control the target camera.
