Real time image matting and synthesizing system

Abstract

The invention discloses a real time image matting and synthesizing system. A blue image matting background is arranged on one wall surface. Another wall surface opposite to the wall surface is equipped with a projection screen. A slide rail is mounted at upper side between the two wall surfaces. A movable device is arranged in the slide rail. The movable device comprises a camera slide block and a projector slide block. A camera fixing mechanism is fixedly connected with the camera slide block. A projector fixing mechanism is fixedly connected with the projector slide block. A double-groove pulley is fixedly arranged on the slide rail. Two pull ropes are winded on the double-groove pulley. One end of one pull rope is fixed on the camera slide block, and the other end is a free end. One end of the other pull rope is fixed on the projector slide block, and the other end is the free end. A camera is mounted on the camera fixing mechanism. A projector is mounted on the projector fixing mechanism. The camera faces towards a photographing target. The projector faces towards the projection screen. The camera and the projector are connected with a computer. The video signals photographed by the camera are input into the computer. The synthesized video signals are output to the projector. The system is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to a real-time image matting synthesis system. Background technique [0002] At present, the existing image matting process requires the actors to use a camera or video camera to shoot in front of a green or blue background with uniform lighting in a special studio. Computer software processes photos or videos, adds background synthesis, and finally exports the synthesized photos or videos. Only in this way can the keying and display of photos or videos be realized, and real-time display cannot be performed. [0003] The main problem of the existing matting process is that the photos or videos must be processed by the computer after the pictures and shooting are completed, and the processing time is relatively long, which leads to a long time from the beginning of the shooting to the actual viewing at the end. It is not real-time, and it is not practical in the exhibition industry. Contents of the invention [0004] The purpos...
