Abstract

The invention provides a multi-source projection seamless edge stitching method and system. The system comprises an edge fusion processor, a digital camera, a control computer, a projection screen and a projector; a geometric correction module, an image segmentation module, a feature matching module and an edge fusion module are arranged on the edge fusion processor; the digital camera is used for acquiring a video signal, and transmitting the video signal to the edge fusion processor; the control computer is used for sending a control signal to the edge fusion processor; and the projection screen and the projector are used for displaying a projected image. By means of the method, a physical stitching seam at the edge of an image can be thoroughly eliminated; and integration and multi-channel seamless stitching of the image are realized.

Description

technical field [0001] The invention relates to a multi-source projection seamless edge splicing method and system, belonging to the field of image processing. Background technique [0002] With the development of science and technology, the pursuit of bright super-large screens, pure colors, and high-resolution display effects has always been a potential requirement for people's visual experience. The desire for large-screen, multi-color, high-brightness, and high-resolution display effects is becoming stronger and stronger, while traditional video walls, projection hard splicing screens, and box splicing walls and other seamed splicing methods lack picture integrity and uniform brightness and color Sex, it is difficult to meet people's requirements in this regard. The edge blending technology that has recently risen rapidly is a new seamless stitching technology that has emerged in recent years. It better improves the visual effect of stitched images and has become the mo...
