Description

Technical Field

[0001] The present invention relates to the field of monitoring, and in particular to a pan / tilt control method, device, system and computer-readable storage medium. Background Art

[0002] There are many protocols used by PTZ devices to access streaming media servers, and the interaction methods of PTZ devices with different protocols are also different. For example, the currently more mainstream ONVIF protocol and GB28181 protocol, of which ONVIF protocol is an international standard, supported by most PTZs, and GB28181 protocol is a domestic standard, supported by mainstream domestic PTZs. When the PTZ uses the ONVIF protocol to access the streaming media server, the streaming media server needs to actively connect to the PTZ, communicate with the PTZ through the SOAP protocol, and send SOAP messages to achieve PTZ control. When the PTZ uses the GB28181 protocol to access the streaming media server, it will actively report to the streaming media server and register. The two communicate through the SIP protocol, and the streaming media server sends SIP signaling to the PTZ to achieve PTZ control. Since PTZ devices with different protocols require different platforms to control, streaming media server developers need to develop different platforms to support PTZ devices with different protocols, which increases development and maintenance costs.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0044] The following combination Figure 1 , Figure 1 A flowchart of a pan / tilt control method provided by an embodiment of the present invention, the method may include:

[0045] S101: receiving a PTZ control request sent by a client.

[0046] The execution subject of this embodiment can be a streaming media server. Furthermore, this embodiment does not limit the specific type of server. It can be classified by chassis structure, such as desktop server, rack server, cabinet server and blade server; it can also be classified by purpose, such as general-purpose server and special-purpose server; it can also be classified by processor architecture, such as CISC (Complex Instruction Set Computer) server, RISC (Reduced Instruction Set Computing) server and VLIW (Very Long Instruction Word) server; it can also be classified by application level, such as entry-level server, workgroup-level server, department-level server and enterprise-level server.

[0047] This embodiment does not limit the specific connection method between the client and the streaming media server, which can be connected by wire or wirelessly. Furthermore, this embodiment does not limit the number of connected clients. This embodiment does not limit the generation method of the pan-tilt control request. Generally, the user can input the request parameters corresponding to the pan-tilt through the client, and the client analyzes the request parameters to obtain the pan-tilt control request, and the client sends the pan-tilt control request to the streaming media server. This embodiment does not limit the specific content of the request parameters, which can generally be commonly used and general, such as device ID (Identity Document), device protocol, device action, moving direction, focal length adjustment, zoom speed and moving speed. This embodiment does not limit the specific content of the request parameters. For example, the movement direction of the device can be set to other movement directions besides up, down, left and right. After the user inputs the command according to the above request parameters, the client parses the request parameters. This embodiment does not limit the parsed content of the request parameters. Among them, since ONVIF (OpenNetwork Video Interface Forum) protocol and GB28181 protocol are two more commonly used pan-tilt protocols, in this embodiment, the device protocol can be parsed into ONVIF, GB28181 and other types, the device action can be parsed into move and stop, the movement direction can be parsed into up, down, left and right, the focal length adjustment can be parsed into zoom in and out, the zoom speed can be parsed into an integer between 1 and 10, and the movement speed can be parsed into an integer between 1 and 10.

[0048] Furthermore, if the client determines that the parsed device protocol type is not a supported protocol preset by the client, the client will issue a protocol incompatibility notification and will not send a control request. For example, if the conversion service in the streaming media server includes the ONVIF protocol and the GB28181 protocol, then for other protocol types other than these two protocols, the client will issue a protocol incompatibility notification. However, the method of this embodiment does not only support these two protocols. If the streaming media server is equipped with conversion services for other types of protocols, then the client can also parse the request parameters of other protocol types, and generate a pan-tilt control request and send it to the streaming media server.

[0049] S102: Convert the pan-tilt control request into a target pan-tilt control request of a corresponding protocol according to the device protocol in the pan-tilt control request.

[0050] In this embodiment, since the ONVIF protocol is an international universal standard, most pan-tilt heads support it, and the GB28181 protocol is a domestic standard, and domestic mainstream pan-tilt head devices also support it, the streaming media server in this embodiment can be a streaming media server with ONVIF protocol and GB28181 protocol conversion services. When the pan-tilt head uses the ONVIF protocol to access the streaming media server, the streaming media server needs to actively connect to the pan-tilt head, communicate with the pan-tilt head through the SOAP protocol, and send SOAP (Simple Object Access Protocol) messages to achieve pan-tilt head control. When the pan-tilt head uses the GB28181 protocol to access the streaming media server, it will actively report to and register with the streaming media server. The two communicate through the SIP (Session Initiation Protocol) protocol. The streaming media server sends SIP signaling to the pan-tilt head to achieve pan-tilt head control. The specific process can be as follows. Figure 2 shown.

[0051] In this embodiment, the streaming media server makes a judgment based on the device protocol type in the pan-tilt control request sent by the client. If it is judged to be the ONVIF protocol, the streaming media server can access the database based on the device ID in the pan-tilt control request to query the specific information of the device. The device information may include the device IP (Internet Protocol) address, device user name, and device password. The streaming media server then interacts with the pan-tilt through the SOAP protocol based on the request parameters and device information, and finally generates a target pan-tilt control request that supports SOAP protocol messages. If it is judged to be the GB28181 protocol, the streaming media server generates an 8-byte PTZ instruction based on the device action, moving direction, focal length adjustment, zoom speed, and moving speed in the pan-tilt control request sent by the client, and generates the generated instruction, the device ID in the pan-tilt control request, and a self-incrementing SN (Sum Number) as the target pan-tilt control request of the SIP protocol.

[0052] Further, this embodiment does not limit the specific steps for the streaming media server to convert the PTZ control request into the target PTZ control request. Generally, when converting the target PTZ control request of the SOAP protocol, the streaming media server can send a SOAP message that calls the Get Capabilities interface in the ONVIF protocol to the PTZ according to the device IP address, and obtain the service address of the PTZ media module and the PTZ (Pan Tilt Zoom, full range movement and lens zoom and zoom control) module. Then, according to the obtained media module service address, as well as the device user name and device password information, a SOAP protocol message that calls the GetProfiles interface in the ONVIF protocol is sent to the PTZ to obtain the Profile Token of the PTZ. The streaming media server judges the device action in the PTZ control request. If it is judged that the device action in the PTZ control request is to stop, the Stop interface in the ONVIF protocol can be used to assign the Profile Token attribute value in the interface to the value of the Profile token of the PTZ, and set the PTZ attribute values ​​in the interface to false, and finally generate the target PTZ control request converted into a SOAP message.

[0053] In this embodiment, when it is determined that the device action in the pan-tilt control is moving, the Continuous Move interface in the ONVIF protocol can be used, and the Profile Token attribute value in the interface is assigned to the attribute value of the Profile token in the pan-tilt. The streaming media server processes the moving direction, focal length adjustment, zoom speed and moving speed in the pan-tilt control request. When the moving direction in the pan-tilt control request is up, the moving speed of the pan-tilt control request is multiplied by 0.1 and the result is assigned to the y attribute under the Pan Tilt (horizontal and vertical movement) attribute in the interface; when the moving direction in the pan-tilt control request is down, the moving speed is multiplied by -0.1 and the result is assigned to the y attribute under the Pan Tilt attribute in the interface; when the moving direction in the pan-tilt control request is left, the moving speed is multiplied by -0.1 and the result is assigned to the x attribute under the PanTilt attribute in the interface; when the moving direction in the pan-tilt control request is right, the moving speed is multiplied by 0.1 and the result is assigned to the Pan Tilt attribute in the interface. The x attribute under the Tilt attribute; when the focus is adjusted to zoom in in the gimbal control request, the zoom speed is multiplied by 0.1 and assigned to the x attribute under the Zoom attribute in the interface; when the focus is adjusted to zoom out in the gimbal control request, the zoom speed is multiplied by 0.1 and assigned to the x attribute under the Zoom attribute in the interface, and finally the target gimbal control request of the SOAP message is generated.

[0054] Further, in this embodiment, when converting the target PTZ control request of the SIP protocol, if the device action in the PTZ control request is stop, the PTZ instruction can be directly assigned as: A50F01017D000033. If the device action in the PTZ control request is move, the moving speed and zoom speed are first processed, and the moving speed in the PTZ control request can be converted into a byte of two hexadecimal digits. When the moving direction is left or right, the moving speed can be set in the 5th byte of the PTZ instruction; when the moving direction is up or down, the moving speed can be set in the 6th byte of the PTZ instruction; when the focal length is adjusted to zoom in or out, the zoom speed can be set to the high 4 bits of the 7th byte of the PTZ instruction, and the low 4 bits are set to 0H. Then the moving direction is processed. When the moving direction is right, the fourth byte of the PTZ instruction can be set to 01H; when the moving direction is left, the fourth byte of the PTZ instruction can be set to 02H; when the moving direction is down, the fourth byte of the PTZ instruction can be set to 04H; when the moving direction is up, the fourth byte of the PTZ instruction can be set to 08H; when the focus is adjusted to zoom in, the fourth byte of the PTZ instruction can be set to 10H; when the focus is adjusted to zoom out, the fourth byte of the PTZ instruction can be set to 20H. Finally, the 8th byte of the PTZ instruction is set to the lower 8 bits of the arithmetic sum of the first 7 bytes. The first three bytes default to A5H, 0FH and 01H, and the remaining bytes not mentioned default to 00H. The above steps generate the corresponding PTZ instruction according to the PTZ control request. The streaming media server then generates the final SIP protocol target PTZ control request with the PTZ control instruction, the device ID in the PTZ control request, and a self-incrementing SN.

[0055] S103: Sending the target PTZ control request to the corresponding PTZ through the device address, so that the corresponding PTZ performs an operation according to the target PTZ control request.

[0056] In this embodiment, the IP address of the connected PTZ device is stored in the database of the streaming media server, and the corresponding device IP address is found through the device ID in the PTZ control protocol. The target control request that is finally converted is sent to the corresponding PTZ through the device IP address. After receiving the target PTZ control request, the corresponding PTZ performs the corresponding operation according to the command in the request. Furthermore, this embodiment does not limit the number of PTZs connected to the streaming media server, nor does it limit the connection method with the PTZ. It can be a wired network connection or a wireless network connection. The transmission speed of the wired network connection is faster and more stable, and the wireless network connection eliminates the problem of wiring. The specific connection method can be selected according to the actual usage scenario.

[0057] This embodiment converts the pan-tilt control request into a target pan-tilt control request of the corresponding protocol according to the device protocol type in the pan-tilt control request, redefines the calling interface and parameters, and shields the communication methods and calling differences between pan-tilt protocols internally, while providing consistent pan-tilt control options externally. This avoids the problem in the prior art of needing to develop different platforms to support pan-tilts of different protocols due to different pan-tilt protocols, and can save developers' energy in developing and maintaining the platform.

[0064] 6.
