Description

Remote pre-visualization system and pre-visualization method utilizing virtual cameras and lighting for virtual production.

[0001] The present invention relates to a remote pre-visualization system and method utilizing a virtual production camera and lighting. More specifically, it relates to a remote pre-visualization system and method utilizing a virtual production camera and lighting constructed to check the effects of a camera moving shot in advance before shooting LED wall-based driving video in a studio, and to provide a more creative and efficient work environment during actual shooting.

[0002] Generally, to film scenes such as car chases in dramas or movies, cameras are installed inside the vehicle to capture the surroundings; however, due to the limited space inside the vehicle, the camera's movement and lighting positions are restricted, making it difficult to create creative shots.

[0003] Therefore, a vehicle is set up on a set and a green chroma mat is installed around it to make the background and the interior of the vehicle recognizable separately through color contrast effects, and then a chroma technique is used to apply CG to the video filmed on the set through post-production.

[0004] However, while this chroma technique has the advantage of creating creative, three-dimensional images from various angles during camera shooting, it has the problem of increasing the overall budget required by adding CG during post-production, and particularly extending the production period depending on the workload.

[0005] Therefore, recently, in order to solve the aforementioned problems, films such as the domestic "Train to Busan" or the overseas "Oblivion",

[0006] A filming method has been developed in which a large-screen LED wall, large enough to extend beyond the camera's field of view, is installed inside a set (studio), and a train or vehicle is positioned in front of the LED wall. By playing a background image of a specific location in high definition through the LED wall, the method creates the effect that the vehicle or train equipped in the set is moving through the actual background image.

[0007] However, this method requires having a large-screen source (hereinafter referred to as the background image) that is played through the LED wall of the set (studio) secured in advance, and

[0008] In particular, as the camera equipped in the set (hereinafter referred to as the studio) must simultaneously film vehicles and the like along with the background image played through the LED wall, the space where the camera is placed and the viewing direction must be considered. Furthermore, since driving footage that resembles driving on a road must be filmed in a state where the real and virtual are mixed, there were often cases where unexpected results occurred or the footage differed from what the director had envisioned, leading to reshoots and delays.

[0009] Therefore, the present invention aims to provide a system and method that can verify the effect of a camera moving shot in advance before shooting an LED wall-based driving video, and provide a more creative and efficient shooting and work environment during actual shooting.

[0010] Accordingly, to solve the above-mentioned problem, the present invention is equipped with a service server capable of generating a virtual studio with mesh conversion based on LiDAR scanning of a studio at the site equipped with an LED wall to determine its size, while also modeling cameras, lighting, and vehicles used at the shooting site to create a database for selective use in the virtual studio, and creating a database for a large-screen background image playable through the LED wall at the studio at the site to play through the LED wall at the virtual studio.

[0011] The system comprises a user terminal configured to connect to the service server to place a camera, lighting, and a vehicle in a virtual studio, set their position values ​​and settings, and set a background image to be played through an LED wall provided in the virtual studio, while also enabling the user to view a video of a vehicle driving as the camera viewpoint changes based on the background image played through the LED wall provided in the virtual studio when the service server plays the background image.

[0074] To explain with reference to this, the present invention includes a connection step (S110), a project creation step (S120), a placement step (S130), a setting step (S140), a shooting and playback step (S150), and a correction and monitoring step (S160), and may further include a collaboration step (S170) according to an embodiment.

[0075] Here, the connection step (S110) is that when the user terminal (1) connects to the service server (10), a web page is opened and an ID and password are entered into the connection window of the web page to verify whether the user is a legitimate user.

[0076] The project creation step (S120) involves displaying a virtual studio containing an LED wall (21) and a ceiling panel (22) on a webpage when it is confirmed that the connected user is a legitimate user, and granting permission to use the virtual studio.

[0077] That is, referring to FIG. 4, after logging in, a webpage (30) is equipped with a plurality of menu buttons (32) and a play button (33), and a project window (31) is displayed. At this time, the project window (31) displays a 180-degree basic screen that allows for a full view of the stage (20) and the LED wall (21), and as the diagonal line moves according to the control of the mouse or keyboard, the operating space, lobby, or ceiling where the director and staff are located can be checked accordingly.

[0078] The placement step (S130) is a step of arranging cameras, lighting, and vehicles in a virtual studio so that they can be positioned respectively based on data stored in the database of the service server (10), and selecting a background image to be played through the LED wall accordingly.

[0079] That is, referring to FIG. 5, a plurality of menu buttons (32) are provided at the top of a project window (31) that displays a virtual studio, and when a vehicle button (32c) among the plurality of menu buttons (32) is selected, a side window (34) is displayed on the left side of the project window (31), and one of the plurality of vehicle icons provided in the side window can be selected.

[0080] At this time, if you select one of the multiple vehicle icons displayed on the side window (34) with a mouse and drag it to a virtual studio, the vehicle is placed on a stage (20) equipped with an LED wall (21).

[0081] For reference, the backgrounds of the camera (23), lighting (24), and LED wall (21) are also selected and arranged in the same way.

[0082] The setting step (S140) enables shooting by adjusting the positions of the camera (23), lighting (24), and vehicle (25) placed in the virtual studio, while also enabling viewing the appearance of the virtual studio that has changed accordingly.

[0083] That is, as illustrated in FIG. 5, when the camera (23), lighting (24), and vehicle (25) displayed on the side window (34) at one end of the project window (31) are each placed on the stage (20), a setting window (35) is displayed on the right end of the project window (31), and through the setting window (35), the position values ​​(Position, Rotation, Scale) are set / adjusted, while the setting values ​​(e.g., Intensity, Color, Temperature, ShadowHardness, SoftSourecRadius, InnerAngle, etc.) are set / adjusted, thereby setting the status of each camera (23), lighting (24), and vehicle (25) placed in the virtual studio.

[0084] The shooting and playback step (S150) involves playing a large screen background image through an LED wall (21) provided in a virtual studio, while shooting a driving video with the LED wall (21) as the background using a camera (23) placed in the studio.

[0085] That is, as illustrated in FIG. 6, after completing the placement of the camera (23), lighting (24), and vehicle (25) in the virtual studio and completing the settings such as detailed position values / setting values, when the play button (33) provided at the top right of the project window (31) is clicked,

[0091] The collaboration stage (S170) is terminated if there are no specific modifications after correction and monitoring are completed. If there are multiple users connected to the service server, the recorded driving video is communicated via voice or text with multiple users (e.g., production company, staff, actors, etc.) connected from different locations to check for additional details or corrections.

[0092] For reference, when the collaboration button (32e) among the multiple menu buttons (32) provided at the top of the project window (31) is clicked, a side window is displayed on one side of the project window (31), allowing users to check the connected users and communicate.

[0093] Additionally, the reshooting step (S180) is terminated if, as a result of consultation with multiple users, it is determined that reshooting is not necessary. Alternatively, to check for additional details or corrections, the position values ​​and settings of the camera or lighting placed in the virtual studio may be changed, or the project completed so far may be saved and the process returned to the project creation step (S120) and repeated up to the consultation step (S170).

[0094] In addition, in the reshooting step (S180), according to the embodiment, a user (e.g., director) or manager (e.g., account manager) currently shooting driving footage may select one of the multiple users (e.g., staff) and grant priority (account usage rights). At this time, the user (e.g., staff) granted priority may adjust the position of cameras or lighting placed in the virtual studio, correct characteristic values, save the project completed so far, and pre-shoot various driving footage while proceeding with a new project, so that it is reflected when shooting at the on-site studio later.

[0095] Therefore, the present invention enables the filming of vehicle driving footage more stably, quickly, and effectively in the on-site studio by conducting various camera tests in a virtual studio in advance before filming driving footage using an LED wall in the on-site studio.
