Green-screen-free matting implementation method for virtual live broadcasting room

The invention discloses a green-screen-free matting implementation method for a virtual live broadcast room, and the method comprises the steps: collecting the image information of the virtual live broadcast room for training, processing all live broadcast room figure and object image types in the high-resolution input virtual live broadcast room image information by using a Background Matting algorithm model to obtain a live broadcast room figure and object feature image set for training; processing specific image blocks on an original high-resolution image by using a Background Matting algorithm model based on the field of live broadcast room figure and object image type identification; adjusting and optimizing algorithm parameters through a cloud-based man-machine interaction port, and carrying out image cutout on unconventional pixel points of figures and objects according to abnormal image types of figures and objects in the live broadcast room; sending the identification result of the image types of the
