First, the concept involved in the embodiments of the present application will be explained.
The thin client is a computing dumb terminal which basically does not need an application program in a client-cloud server network system; the system is communicated with a cloud server through some protocols, and then is accessed to a local area network. The thin terminal is a device using desktop cloud, and is generally a device embedded with an independent embedded operating system and capable of being connected to a desktop running on a cloud server through various protocols.
Desktop cloud, which can access cross-platform applications and entire client desktop through thin clients or any other network connected devices. Desktop cloud and cloud desktop are the exposition of different emphasis points of the same object.

It should be noted that the numbers of the lens devices and the virtual machines in fig. 1 are merely illustrative and are not limited to specific ones.
The camera terminal in the embodiment of the application is a thin terminal after being modified, wherein the modified mode can be that some plug-ins are installed, so that the modified camera terminal has the capability of being connected to a desktop running on a cloud server. Therefore, the existing resources can be fully utilized, and the maximum application of IT (Information Technology) assets is realized. Therefore, the embodiment of the application is a specially-made thin terminal type photographing terminal which is connected with a cloud server to perform photographing and data storage operations.
Specifically, the photographing device in the embodiment of the application comprises two parts, a photographing terminal and a lens device, wherein the photographing terminal is provided with a high-bandwidth network card, a small amount of storage media and an operating system which supports photographing and can be connected with a virtual machine; the lens device is a general term, and includes each imaging component, and the cooperation and application of each component and the imaging principle can refer to the related art, which is not described herein. In the actual application process, the photographing terminal and the lens device are matched for application, and a corresponding driving program needs to be installed in the cloud or the local of the photographing terminal. It should be noted that the type of the camera terminal and the corresponding lens device can be replaced, the type of the camera terminal mainly affects the image viewing experience and the interactive mode of the user at the front end, and the type of the lens device mainly affects the image quality level and the type of the imaging, for example, the lens device of the infrared imaging or thermal imaging type can be applied. The photography mode is called a cloud camera mode; the platform formed by the desktop cloud-based photographing system is called a cloud camera platform.
In the embodiment of the application, the desktop cloud-based photographing system comprises photographing equipment and a cloud server, the photographing equipment comprises a photographing terminal and a lens device, the cloud server comprises at least one virtual machine, connection between the photographing terminal and the virtual machine is established through cooperation between the photographing equipment and the cloud server to control the corresponding lens device to shoot, and then images are generated according to data streams obtained through shooting and displayed on the photographing terminal. Compared with the traditional photography mode, the data security and the information security are higher, and the data cannot be illegally utilized due to the loss of a camera or the damage of a storage medium; the complicated steps of importing and exporting data are reduced, in addition, the local processing data volume is small, and the cruising ability of the photographic equipment is further improved; the hardware requirement of the client is reduced, the resource utilization rate of the server is improved, and the server is convenient to maintain.
The operation of the camera terminal on the cloud server may be in a key mode or a touch screen mode, which is only an example and is not limited in particular.
Optionally, the connection request includes a device identifier of the camera terminal or a user identifier of a user to which the camera terminal belongs, and the cloud server verifies the validity of the camera terminal according to the device identifier and/or the user identifier. The device identification and/or the user identification may be authenticated when the photographing terminal accesses the server, for example, it is determined that the photographing terminal to be accessed is not an illegal photographing terminal.
For example, the connection request further includes device information of a lens device matched with the photographing terminal, after the photographing terminal and the target virtual machine are connected, the target virtual machine determines whether the target virtual machine includes a driver of the lens device according to the device information of the lens device, and if not, downloads the driver of the lens device according to the device information of the lens device and installs the driver. In addition, the connection request can also judge whether the access device is a photographing terminal or other electronic devices such as a mobile phone, a computer or a tablet. Specifically, each lens device can be operated only by the matched driver, whether the corresponding driver exists in the target virtual machine is judged according to the device information of the lens device, and if the corresponding driver does not exist, the corresponding driver can be downloaded according to the device information of the lens device for installation. In a specific example, the device information of the lens apparatus may be a model of the lens apparatus or the like.
Next, driving in the embodiment of the present application will be explained. The driving in the embodiment of the application is a conventional driving and a cloud driving. The conventional drive is a drive mounted on a photographing terminal, and mainly functions to perform an image pickup operation using a lens apparatus. The download of the conventional drive can be carried out by connecting a cloud server. In a specific example, the same camera terminal may support the installation of five conventional drivers. The cloud driver is a driver installed on the virtual machine, and the driver mainly calls a lens device connected with the camera terminal through a network protocol to perform data stream transmission. In a specific example, the installation of the cloud driver may be performed by reading a driver installation package stored in the shared storage in the virtual machine, and the number of drivers that a virtual machine supports to install is not limited.
In addition, in the cloud camera mode, the photographing terminal communicates with the cloud server through a built-in wireless network card, and after the user identity or the effectiveness of the photographing terminal is determined, the user virtual machine in the cloud server can be mapped, and the user virtual machine can be also called a target virtual machine. The user remotely operates the target virtual machine to realize the setting and shooting of the shooting terminal. It should be noted that the photographing terminal only performs imaging, and an image on a display screen of the photographing terminal is returned to the photographing terminal from a data stream after the target virtual machine calls the lens device. It should be noted that, in the cloud camera mode, all data processing and storage are completed on the virtual machine, and do not occupy excessive resources and internal storage of the photographing terminal, so that, in design, the size of the photographing terminal will be significantly smaller than that of the conventional photographing device, and the cruising ability is far greater than that of the conventional photographing device.
In an actual application process, the cloud server is further configured to: receiving an access request of an intelligent terminal; and displaying the corresponding image data to the intelligent terminal according to the access request. Besides receiving the access of the camera terminal, the server can also support the access of other intelligent devices such as an intelligent terminal, for example, a mobile phone. Specifically, the intelligent terminal initiates an access request, and the server performs identity verification on the access request, so that illegal intelligent terminals are avoided. In a specific example, the presentation process of the image data may be: the cloud camera display method is used for displaying image data shot by all cloud cameras of a user in a classified mode after logging in through the intelligent device, and the classification rules can be that the image data of each cloud camera serves as a category and then are displayed on a display screen of the intelligent terminal in a classified mode. It should be noted that, the presentation of the data of all the cloud applications of the user can be presented, because a storage manner of shared storage is adopted in the past, and all data of one user are stored in the same storage device or the same storage system.
In addition, the working modes of the photographing system further include a local camera mode, and if the cloud camera mode of the photographing system fails to be started, the photographing system is switched to the local camera mode. The local camera mode is suitable for the situation without network signals, and in the local camera mode, the driver of the corresponding lens device can be installed and then used, and the driver can be downloaded and installed after being connected with the cloud server. The processor performance of the photographic equipment is relatively weak, so that the photographic equipment can easily enter a high-load state in a local camera mode, and the service time is short; and the storage is small, so that long-time photographing cannot be realized. Therefore, the cost camera mode is switched only after the start-up of the cloud camera mode of the photographing system fails. Compared with the local camera mode, the cloud camera mode has remarkable improvement in performance, endurance, data security, information security and storage space. It should be noted that, for the detailed principle and flow of the cloud camera mode, reference is made to the description of the foregoing embodiments, which are not repeated herein.
For example, if the target virtual machine does not receive the data stream within a set time range after sending the shooting instruction to the corresponding lens device, all image data stored in the current target virtual machine is saved in a dropped state. In a specific example, during communication between the virtual machine and the lens device, the purpose that the driving command can be transmitted in the Internet is achieved by encapsulating the driving command with TCP/IP (Transmission Control Protocol/Internet Protocol).
In the embodiment of the application, when the photographing terminal works in a cloud camera mode, a crisis handling mechanism is automatically started, in the mechanism, when a virtual machine works by using a lens device, if physical equipment is damaged, a target virtual machine possibly does not receive a data stream within a set time range after sending a shooting instruction, at the moment, the mechanism is triggered, and all data just shot in the memory of the current target virtual machine can be stored in a falling manner under the mechanism. Therefore, by applying the cloud camera technology, all computing work and storage work are completed in the virtual machine in the cloud server, and even if the camera is damaged, the data stored in the virtual machine cannot be lost.
In a specific example, the photographing terminal is further configured to receive a control instruction of the intelligent terminal, where the control instruction is used to control a lens device matched with the photographing terminal.
In the actual application process, a user can purchase some basic cloud services on the cloud platform, such as more virtual machines, the memory, the storage capacity, the processor frequency and the like of the virtual machines, and some advanced cloud services of the camera terminal based on image optimization or intelligent device operation.
Optionally, if the user purchases advanced cloud services, the user may also access the cloud camera through another intelligent terminal to control the photographing terminal. It should be noted that the connected cloud camera must be in a state of being used by the photographing terminal, that is, the same cloud camera is used by both a smart terminal and a photographing terminal, and at this time, the user can use the smart terminal to operate the lens device of the photographing terminal through the cloud camera. It should be noted that, one user may purchase more virtual machines by a service provider, support one camera terminal corresponding to a plurality of virtual machines, and support one virtual machine to be connected by a plurality of camera terminals of the same type, but support only one camera terminal to be connected at the same time.
It should be noted that only one camera terminal can use the lens device at a time, that is, when the intelligent terminal operates the lens device, the camera terminal cannot operate the lens device, and the control mode of the intelligent terminal and the camera terminal on the lens device is a preemption control mode, that is, a first-come first-control mode.
Optionally, the photographing terminal is a thin terminal. In the embodiment of the application, the Video computing system is mainly used for a virtual machine connected and operated by a camera terminal on a cloud server. The operating system is provided with a driver installation system, and can automatically select and install a corresponding driver from a shared memory according to the device information of the lens device of the connected shooting device. The drive is mainly used for realizing the operation and the lens device setting when being controlled by the thin photographing terminal. In one particular example, the thin terminal may include a browser system.
In addition, the embodiment of the application also has the following beneficial effects: due to the adoption of the cloud camera shooting mode, the volume of the camera shooting equipment of the embodiment of the application is obviously smaller than that of a traditional camera shooting device. In addition, the introduction of other intelligent terminals redefines the mode of remotely controlling the camera by a third party, and the intelligent camera is more intelligent. The cloud service platform personal space is provided, people communication is achieved, data safety is guaranteed, the system is based on the IDV (Intelligent Desktop Virtualization) technology, and management and maintenance are convenient.
