Description
Technical Field
The present invention relates to an image pickup apparatus, and more particularly, to a multifunctional integrated image pickup apparatus.
Background
In recent years, recording and broadcasting systems are more and more widely applied, the requirements of real-time recording, live broadcasting, later-period on-demand and the like of various activities in various industries are rapidly increased, and recorded video files are used for recording, learning and sharing. Especially in the fields of meetings, education and training, stages, internet entertainment live broadcast and the like, the demand of the market live broadcast equipment is obviously increased.
However, emerging market demands place considerable demands on "cost performance", "ease of use", etc. On one hand, many users do not need broadcast television grade image quality, and the users need cheap and durable products; on the other hand, users basically do not have professional broadcast media training, and are far from understanding professional direct broadcasting and live broadcasting equipment, and the users need simple and easy-to-learn products. Which presents a significant challenge to the prior art.
Because the current civil-level live broadcast and recording system has the following two types:
firstly, a studio system: the existing studio system mainly depends on a studio host computer with 1X 86 server architecture, and a video capture card, a blue-green key keying system and live broadcasting guide software are additionally arranged in the host computer. The core signaling logic is:
1. and collecting the pictures of the high-definition camera by a video capture card.
2. And the PCIE slot is communicated with a server mainboard, and a color key keying system is used for calling the picture flow.
3. And the picture stream is coded by built-in direct broadcasting and live broadcasting software and is pushed to a third party direct broadcasting streaming media server in a streaming media form.
Such core usage logic presents two problems:
1. the keying system of the blue/green key and the live broadcasting guide software consume CPU and GPU resources of the server, so that the cost and the energy consumption of the server are high.
2. The high-definition camera is external, so there are acquisition card cost, wiring cost, installation cost.
Secondly, a wireless portable recording and broadcasting system:
the existing wireless portable recording and broadcasting system mainly uses a WIFI-AP module as a networking core to generate a WIFI hotspot base station, each wireless camera is accessed through a WIFI network, and then a wired network module with a built-in ARM mainboard is connected with the wireless AP module through a built-in switch module of a host, so that networking of the ARM mainboard and the wireless cameras is realized on a physical layer and a data link layer.
Then, an embedded linux system is operated on the ARM chip, the encoding and decoding chip is called to decode and render the streaming media of the wireless camera through built-in director and live broadcast software, and the software pictures are output to a touch screen of the camera body.
Such core usage logic presents two problems:
1. the AP module is arranged in each wireless camera, and each wireless camera can be a WIFI hotspot base station. Theoretically, the scheme only needs 1 WIFI hotspot base station, and all the other devices are access points. This type of scheme actually increases the cost of WIFI networking significantly.
2. Each wireless camera is a small-sized ARM computer, and generally has functions of streaming media encoding, live broadcasting and recording. However, in the existing scheme, all the pictures are connected to the portable recording and broadcasting host computer and then are recorded and controlled in a unified manner, so that an expensive recording and broadcasting host computer is added in hardware configuration, and the cost of a user is increased.
Therefore, it is an urgent need for those skilled in the art to develop a multifunctional integrated image pickup apparatus.
Disclosure of Invention

Furthermore, the x86 industrial control mainboard of the host is provided with a touch screen interface module and is connected with a standard portable touch screen on the market, so that the host and software can be conveniently controlled.
The scheme of the invention is realized in detail:
1. video channel presentation (screen rendering):
when the program guide and record play software runs, multiple spare video channels are loaded firstly, and the video channels can come from cameras, video files and the like. In a general studio or a recording and broadcasting system, a scheme of CPU soft solution or GPU hard solution is adopted, and the scheme has high requirements on the CPU and the GPU, thereby bringing large hardware overhead. How the present invention renders various common videos will be described as follows:
the channel with the camera comprises: the video data stream (generally in YUV format) is obtained from the USB camera module through the drive of the USB camera, and is decoded by a professional decoding chip of the encoding and decoding accelerator card, and finally rendered by the director recording and broadcasting software and displayed on a Windows interface.
An external network camera: the streaming media (generally RTSP, RTMP or HLS) of the external camera is obtained through an IP network, then decoded by a professional decoding chip of the coding and decoding acceleration card, and finally rendered by the program guide and recording software and displayed on a Windows interface.
2. And (3) encoding of a live channel:
a video program is obtained by processing a plurality of video channels by a user, such as switching, splicing, special effects, and the like, so that the program guide and recording software generally needs to encode a live channel, and the live channel can be used for program recording, program live broadcasting, third-party system monitoring and calling, and the like.
At this time, if the design idea of the traditional studio is used, the idea of CPU soft-programming or GPU hard-programming or directly using the embedded special soc needs to be adopted, and such design ideas all have a cost problem. In the invention, the coding work is not finished by a CPU or a GPU, but is finished by a special hardware coding chip carried on a coding and decoding accelerator card, and then the coded H.264/H.265 data stream is transmitted back to the director software. After the h.264/h.265 stream is acquired, the director software performs streaming media encapsulation or video file encapsulation (the CPU overhead of such encapsulation is low), and functions such as streaming media live broadcast and video recording are realized.
3. The realization of the function of virtual background image matting:
the director and recording software on the market at present realizes the function of virtual background matting, and generally adopts a GPU rendering mode to realize the function, however, the cost for realizing high-quality virtual background matting is very high, so that the cost of the current studio (especially a virtual studio) system is very high, and the system structure is very complex. The invention uses the special color key image matting chip of the coding and decoding accelerator card to carry out the specific color matting of the video channel to obtain a transparent foreground channel, and then the picture is superposed on another channel to obtain a virtual background image matting channel.
The device has the following specific application:

A single machine can realize the virtual studio system.
2. The wireless recording and broadcasting system can be connected with a plurality of wireless cameras through an external USB wireless network card, and then the streaming media pictures of the cameras are pulled through an IP network and the pan-tilt control is carried out, so that the wireless recording and broadcasting system without a recording and broadcasting host is formed.
3. The portable touch screen can be externally connected with a standard portable touch screen on the market, and a host and software can be conveniently controlled.
4. The prompter software can be installed in the operating system and is externally connected with a dedication screen, so that word drafts can be conveniently provided for a photographer in the recording process.
The essence of the invention is a technical solution, and the core of the invention is as follows: various concepts such as recording and broadcasting, broadcasting guide, live broadcasting, virtual background matting, wireless video transmission and the like are integrated into a host, and the host is packaged into a device with the appearance similar to a pan-tilt-zoom camera.
The device also comprises a plurality of peripheral accessories which can be matched with the device, and the device can realize more functions by matching a wireless WIFI module, a wireless Bluetooth module, a touch screen interface module and the like, is applied to various scenes, and can solve the following existing problems:
1. the existing problems of the virtual studio system are solved:
the invention mainly solves the problems of excessive bulkiness, redundancy and high cost of the current studio system.
The equipment that current studio systems need to be equipped at least includes: the invention has the advantages that the camera, the server-level studio host, the cabinet, the video acquisition card and the like are adopted, and only one device is needed, so that the heavy cabinet and the server are omitted, and the cost is greatly reduced.
2. The current problem of wireless portable recorded broadcast system is solved:
the invention can also solve the problem that the current wireless portable recording and broadcasting system needs to be provided with a host independently.
The current wireless portable recording and broadcasting system is generally in a mode of 1 host machine plus N wireless cameras, but the invention can help users to save 1 host machine or 1 wireless camera, thereby achieving the effects of reducing cost and facilitating deployment.
Compared with the prior art, the invention has the advantages that: the power consumption of the special hardware coding chip is low, and the high-speed mini-pcie protocol slot can guarantee the transmission bandwidth. The invention transfers the work of coding, decoding, rendering, matting and the like which needs a large amount of expenses of a CPU and a GPU to the coding and decoding accelerator card, thereby greatly reducing the configuration requirements of the CPU and the GPU.
From a hardware perspective, the architecture of the host is changed from the x86 server level or the dedicated embedded level to the x86 industrial control level of low power consumption and low configuration, so that the scheme does not need expensive main boards, CPUs and GPUs, and expensive customized embedded main boards. Secondly, since most of the existing CPUs (particularly CPUs of intel and AMD companies) have integrated GPUs with simple functions, the scheme has low requirements on GPU configuration, and thus expensive professional graphic display cards do not need to be equipped separately. Thirdly, due to the reduction of power consumption, the power supply stability design and the electromagnetic interference design of the mainboard become simple, a high-power ATX power supply is not needed, a standard 12V direct-current voltage-stabilized power supply with higher yield and lower price can be used, and the cost is further reduced. Fourthly, the cradle head camera and the host are designed into the same machine body, so that the equipment number and the system complexity are reduced, and the wiring, power supply, construction and debugging costs are reduced.
From the perspective of software, firstly, the invention is based on the design of an x86 industrial control mainboard, a standard linux or Windows system can be run on an x86 mainboard, and a mature operating system has strong resources and multithread management capability and also has a large number of mature stable libraries, thereby reducing the threshold of software development. And secondly, a customized embedded mainboard is not needed, so that the workload of stability testing, drive debugging, peripheral configuration and the like is greatly reduced. Thirdly, mature coding and decoding accelerator card (or acquisition card) products are available in the market, and many manufacturers open SDKs for developers to use, so that a lot of workload can be reduced in the development process of the direct broadcasting and live broadcasting software, particularly in the development of coding, decoding, image matting and the like. Finally, because of the high technical threshold of embedded software development, the labor cost of x86 software development in the industry is generally lower than that of embedded development.
