Real-time visualization method and system suitable for film and television virtual shooting and production

Abstract

The invention discloses a real-time visualization method and system suitable for film and television virtual shooting and production, and relates to the field of photography, and the method comprises the steps: mounting an LED ring screen in a photostudio according to a preset specification, and setting the refresh frequency of the LED ring screen according to a preset frequency; capturing a background image under the condition that the LED ring screen background, the role target and the camera coaxially move through a photographing servo system, and obtaining a special photographing image of the special photographing target; acquiring a sensing signal of the sensor, acquiring a contour space of the role target according to the sensing signal, transferring a background sub-screen in the LED ring screen according to the contour space, and acquiring an action image of the role target in the background sub-screen; and when the image is captured, fusing the action image, the background image and the special shot image through the shooting servo system, and obtaining an omnibearing real-time interactive image. According to the invention, synchronous shooting of the visual special effect and the role target is realized, the production of the visual special effect is preposed, and the cost and the period of later production are greatly reduced.

Description

technical field [0001] The invention relates to the field of photography, in particular to a real-time visualization method and system suitable for virtual filming and production of film and television. Background technique [0002] The main scene and environment carrier for film and television shooting is the studio. In the process of film and television shooting, production and the development of visual special effects technology, the digital studio has undergone several technological changes: the first generation of digital studios used green or blue color filter paint. Layer background, manually record the positional relationship between the character and the camera, light intensity, angle, etc. during shooting, track the recorded data during post-production, and achieve visual effects synthesis and high-resolution with real or computer-generated scenes, objects, and characters. rate rendering. The second-generation digital studio uses a green or blue color filter coati...

AI Technical Summary

Problems solved by technology

[0003] Although compared with the first generation digital studio, the second-generation digital studio added a large LED screen, and achieved preliminary synthesis on the shooting site, which has relative control over the production and synthesis of special effects, but both generations of digital studios require manual labor. A large number of data records are made on the positional relationship between the shooting character and the camera, light intensity and angle. Operators’ personal factors lead to a large number of errors and unpredictable errors, and the actual results after post-production and rendering are often difficult to fully meet expectations

At the same time, due to the detailed processing of difficult movements and body language performed by the actors in the later stage, the characters often need to have a partial green sub-screen to filter out the outline space, and the existing green sub-screen is usually fixed at one place on the screen, in a relatively fixed scene During shooting, it cannot follow the movement of the character target

At the same time, the existing special shooting targets are often added in post-processing, so the real actor roles and props cannot be in the same scene during the shooting period, so that the actors have no references and interactive objects during the shooting process, and can only perform and perform based on their personal imagination. shape creation
