기존의 얼굴 캡처 기술은 이제 매우 성숙해졌습니다. 현재 대부분의 얼굴 캡처 시스템은 빛에 민감한 마니를 연기자의 얼굴에 붙여서 얼굴 표정을 캡처합니다. 그러나 높은 장비 및 소프트웨어 비용으로 인해 사용이 제한됩니다. Apple의 ARkit은 얼굴의 특정 토폴로지 구조 정보를 캡슐화하고 모션 캡처 기술을 사용하여 보조 마니 없이 가장 간단한 방법으로 정확한 위치 지정 및 얼굴 표정 감지를 달성합니다. 그러나 Blendshape은 정보가 적이 때문에 얼굴 캡처의 효과가 이상적이지 않습니다. 간단한 얼굴 캡처만 수행할 수 있어, 영화 및 게임에 적요하기 어렵습니다. ARkit의 Blendshape를 친목회에 대한 연구입니다. 안면 근육 움직임의 정보를 제공함으로써 Apple의 ARkit에 표시되지 않은 얼굴 캡처의 효과를 향상시킵니다. Traditional face capture technology is now very mature. Most current face capture systems capture facial expressions by attaching light-sensitive manias to the actor’s face. However, the high cost of equipment and software is limited to use. Apple’s ARkit encapsulates face-specific topology structure information and uses motion capture techniques to achieve accurate positioning and facial expression detection in the simplest way without auxiliary mani. However, Blendshape has less information, so the effect of facial capture is not ideal. I can only perform simple face capture. It’s hard to apply to movies and games. It’s a study of ARkit’s Blendshape on social gatherings. Improves the effectiveness of facial capture not shown on Apple’s ARkit by providing information on facial muscle movements.

Virtual production technology is becoming more mature and is widely used in the production of video content such as movies, drama series, and advertisements. In the two solutions of virtual production (Live LED Wall Cinematography and Live Compositing), the virtual camera and the real camera are required to be identical, that is, after the synchronization of the intrinsic hardware parameters of the real camera and the virtual camera, the exposure parameters of the real camera are changed during shooting, the corresponding parameters of the virtual camera must also be changed to ensure the consistency of the picture. At present, most virtual production studios use camera control systems that are transformed from broadcast camera consoles usually require cumbersome accessories and high prices. During the actual production process, a camera control system using the Arduino development board is found, which inherits the characteristics of easy-to-operate and strong adaptability of the Arduino development board. The serial digital interface camera control protocol provided by Blackmagic Design (BMD SDI CCP), allows the virtual camera (CineCamera) in the virtual production engine Unreal Engine 5 (UE5) and the real camera to communicate in real-time through the use of serial communication. This paper uses literature analysis to explore the necessity and functional requirements of virtual production camera control systems and the feasibility of the virtual production camera system proposed in this study through analysis of academic journals, industry white papers, professional practitioners, and organization presentations. Descript the hardware requirement and design code for the camera control system, verify the feasibility of the system through empirical research, and provide a camera control system that can be customized for individuals or teams who want to make video content through virtual production.
