Description

System for creating performance content having visual effect}

The present invention relates to a performance content production system supporting visual effects, and more particularly, a performance is photographed at a plurality of points through a plurality of cameras against a background of a chroma key installed at a plurality of levels, and then visual effects for the chroma key region are added. The present invention relates to a performance content production system that supports visual effects capable of generating a performance video by performing video synthesis for a performance and then providing the result as performance content that can be selectively viewed from multiple viewpoints to a user terminal through a communication network.

Recently, the number of users who want to watch various performances such as plays, musicals, operas, concerts, etc. is increasing. However, since they have to visit the concert halls to watch these performances, it is difficult for users who have difficulty visiting the concert halls to easily access the performances.

In addition, it is becoming more and more difficult to visit concert halls due to the recent outbreak of various infectious diseases, and accordingly, performing arts companies that have difficulty holding performances are overcoming these difficulties by providing content created by filming performances in the absence of spectators. .

However, since the content created by filming a performance in the conventional way cannot escape the limitations of a 2D flat image filmed at a fixed point of view, it is difficult to provide the 3D liveliness provided in an actual performance hall, and performances are performed only at a fixed point of view. There is a problem in that a performance experience obtained from a different point of view or an actual viewing point cannot be provided because the image is provided.

In addition, in recent real performances, screens are arranged and images are played through the screen to provide various visual effects to further improve the realism of the performance. In addition, there is a problem in that the liveliness of the visual effect using the screen in the actual performance hall is greatly reduced through the content.
