2. Equipment selection of studio

 

The Virtual Reality Interactive Studio is equipped with six cameras, three of which are for live shooting. The cameras are host lens, guest lens and panoramic lens respectively. The cameras are Kaidi broadcast 4kptz camera Kaidi 4K camera control integrated camera kd-sk580uh. The virtual matting area is also a 3-machine configuration. The virtual matting area plans to configure a deep blue box to realize the production of 3D virtual studio. This scheme uses the top tracking technology of virtual studio, and takes advantage of the control advantages of kd-sk580uh camera to realize the virtual studio with tracking. Generally, the virtual studio with tracking is the host tracking, that is, only the host This virtual tracking studio is designed with three cameras. We need to make sure that each camera can track. In this way, the effect of our virtual scene will be very real and gorgeous, making the studio multi perspective and three-dimensional. Kd-3dvc990n, a 3D virtual all-in-one system of Kaidi, is adopted as the virtual host of the guide. For the sake of safety, a hardware lossless 8-channel pilot switching station with loop out is set in the middle, and six channel recording modules are added. These three devices are the most important core equipment of the studio.

 

3. Description of main equipment selection

 

 

 

3.1 front end camera

 

 

 

The first is the camera. This purchase has higher requirements for the camera, which requires the camera to shoot with better picture quality. The camera should be suitable for shooting under the complex lighting of the stage. The scene color collected by the camera is always restored to be real, free from the interference of environment and light, with high-quality imaging. The color restoration of the camera is good, and the illumination should also have a good performance, in the dim light There is no noise when shooting in dark light, so the layout of the imager of the camera should be large enough. Because there are many photographers required when shooting in multiple positions, many units lack professional photographers, so the camera can be remotely controlled, that is, the camera lens can be pushed, pulled, swayed, pitching, and set white balance, aperture, etc. can be remotely adjusted. According to the above requirements, the camera selection of this scheme is kd-sk580uh, which is an integrated camera with broadcast level and camera control.

Kd-sk580uh technical specification sheet (see http://www.xkd.com.cn )：

 

 

 

Kd-sk580uh is a kind of camera that can be controlled remotely. It solves the problem that many photographers are needed in the multi position on-site shooting business. It is a way for the director to adjust and set the white balance and aperture of the camera by controlling the push, pull, shake, pitch and pitch of the camera remotely At the same time, the director, tuning, recording, live broadcasting and control can be completed in one go, and one director can complete the live production of a multi seat scene.

 

 

 

The camera has broadcast level signal quality. The image imager of kd-sk580uh 4K camera is 1.0 (1 inch) backlight Exmor R CMOS imager, with a resolution of 3840 × 2160 and effective pixels up to 12.4 million, realizes 4K image acquisition at broadcast level. The camera has the interface of traditional professional camera and the latest hdbaset interface in the industry. It provides 20gbp / s signal transmission without compression and delay, fully meeting the requirements of 4K signal transmission at broadcast level. The pan tilt of the camera adopts servo motor with high precision It is fast and extremely quiet. The camera starts, brakes and moves very smoothly, which can't be achieved by ordinary people. The camera has many elements that make it competent for professional broadcast level EFP business. With the combination of virtual and real of media network, the Interactive Studio has many slots (6 slots), and the studio space is narrow, so the shooting scene can not accommodate multiple photographers, and the cost of shooting personnel with up to 6 slots is very high. For the above reasons, this scheme adopts kd-sk580uh.

 

 

 

3.2. All in one director and recorder

 

 

 

Financial media attaches great importance to the safety of program production in the studio. Generally, the key equipment adopts the signal processing, storage, transmission and other backup schemes of dual standby. In this studio, we connect the six cameras in the studio to the Caddy's all-in-one broadcast and recording machine through 3g-sdi cable. The all-in-one broadcast and recording machine first records six channels of six machines, and then broadcasts through caddy The six channel recording units of kd-bc800h record six MP4 files of constant frame and constant code, and record the initial signal collected by the camera. Kd-bc800h is sent to 3D virtual all-in-one machine through the SDI ring of kd-bc800h. As a pure hardware guide Station, kd-bc800h can also do guide switching.

 

 

 

Kd-bc800h has a built-in 8-channel high-definition mixed stunt station, and hardware full interface mixed input, realizing 4:4:4 lossless hard cut. The video input of kd-bc800h integrates SDI × 8, ring out SDI × 8 and HDMI × 2 interfaces, and combines with KD camera control all-in-one machine to realize a 75 Ω coaxial line control and transmit five channel signals. The combination of kd-bc800h and KD camera control all-in-one machine is a combination It is a seamless combination of Jackie Chan, which has obvious advantages in multi position shooting.

 

 

 

The audio part of Kaidi all-in-one broadcasting and recording machine also has irreplaceable technical characteristics. It integrates digital mixer and analog mixer, and realizes the mixing of digital audio and analog audio with reliable hardware. It not only integrates many necessary functions of mixer, but also solves some very difficult problems in the industry, such as the sound quality of analog audio collected by various XLR professional microphones There is a difficult problem in the industry that the audio is not clear when it is mixed with the digital audio embedded in the microphone of the on-site camera. This all-in-one machine has a built-in hardware audio delayer, which processes the audio through the encoder. First, the input digital audio is synchronized with the input analog audio, and then the audio and video are accurately synchronized. The application of this technology provides a good hardware platform for complex audio processing, and it is also one of the few products in the industry that can solve this problem.

3.3 3D virtual all in one machine

 

Kaidi 3D virtual all-in-one system is a highly integrated device, which is small, light and powerful. A portable device includes all functions. The detailed parameters of the device are shown in the table below. At the same time, the virtual all-in-one system is a three-dimensional virtual system with tracking, which cooperates with kd-sk580uh camera of the same brand of Kaidi Xingye to realize synchronous follow-up of camera mobile scene, with accuracy.

 

Kaidi Xingye virtual studio can easily achieve large in-depth shooting effect, and the scene can be changed at any time. It not only saves space than the real scene, but also presents better and more diverse shooting effect. The picture on the left is a picture of the studio, which is realized by three-dimensional virtual. All objects and lighting effects are synthesized by virtual synthesis. Moreover, we can change the style at any time. Some effects can't be achieved by real scene shooting. For example, the actual shooting effect of the camera on the large screen is far less than the effect of virtual presentation, and the shooting of light reflection. In addition, for the shooting of large-scale activities such as product launch, some real scene shooting costs will be very high, and others will be difficult to achieve. Virtual reality can be achieved as long as you can think of it.

 

 

All from the perspective of practical application or from the perspective of cost control, the application of 3D virtual system is of great significance. With the progress of science and technology, virtual matting technology has a qualitative development. The new mask matting technology has lower requirements on the cost of lighting and environment, and is cleaner. It can achieve good results even in the stray light. With the progress of algorithm, it is possible in the future Realize no background matting.

 

As another important technology of 3D virtual studio, 3D virtual engine, with the launch of 64 bit win10 and i9900 multithreaded CPU, plus more and more powerful GPU, 3D scene will be more delicate and realistic, with more fine mapping and more perfect light reflection rendering.

 

The above business needs, coupled with mature technology means, make us choose products with high technology content, high integration and high intelligence in the construction of studio today.
