本发明涉及一种基于LED背景墙的电影虚拟化制作方法，特别涉及一种基于深度信息实时可变绿幕生成方法及抠像方法，属于电影虚拟化制作领域。针对现有制作技术中存在的溢色和绿幕穿帮现象，本发明提出一种基于深度信息实时可变绿幕生成方法及抠像方法，利用深度摄像头获取被摄主体的轮廓，并将处理后的被摄主体轮廓区域作为绿幕或蓝幕区域投射到LED背景墙上，替代原本大面积的四边形绿幕或蓝幕，减小对被摄物的溢色影响及绿幕穿帮概率，提高拍摄画面的质量，并且利用前期拍摄时录制的绿/蓝幕轮廓，在后期制作中快速地进行抠像制作。本发明减小LED背景墙中蓝/绿幕的面积，从而减少制作过程中的绿幕影响，提高影视作品质量。 The invention relates to a movie virtualization production method based on an LED background wall, in particular to a real-time variable green screen generation method and an image matting method based on depth information, and belongs to the field of movie virtualization production. The invention provides a real-time variable green screen generation method and an image matting method based on depth information aiming at the phenomena of color overflow and green screen penetration in the existing manufacturing technology, a depth camera is used for acquiring the outline of a shot subject, and the processed outline area of the shot subject is projected to an LED background wall as a green screen or blue screen area.
