Embodiment 1

[0101] Embodiment 1: Real-time splicing of five video streams with a resolution of 3840*2160 collected by a multi-eye fisheye camera.

[0102] Since the fisheye lens has serious radial distortion, it is necessary to correct each frame of video image before registration, projection and fusion. In the present invention, in order to avoid the influence caused by moving objects passing through the suture line and different illumination differences, a video fusion algorithm based on dynamic optimal suture line and improved fade-in and fade-out method is proposed. Firstly, through the background removal algorithm based on mixture of Gaussian (MOG), background removal is performed on each frame of video image to obtain the foreground image. Then according to the corresponding objective function, the optimal suture line algorithm based on dynamic programming is used to obtain the optimal suture line without moving objects, and finally the improved gradual in and out method is used to ...

Abstract

The invention discloses a video fusion algorithm based on a dynamic optimal suture line and an improved fade-in and fade-out method, and belongs to the technical field of video information processing. The method comprises the steps of: acquiring a real-time video stream with an overlapping area through a multi-view camera system; extracting feature points of the overlapped region, performing rough matching and purification on the feature points, and calculating an internal reference matrix and a rotation matrix of each camera by combining a beam adjustment method; performing spherical projection on images between different visual angles and twisting the images to the same reference plane, and then splicing video images by adopting an optimal suture line algorithm, aiming at the situation that a moving object passes through an image overlapping area to generate double images and blurring; adopting an optimal suture line dynamic updating algorithm to avoid ghosting and blurring phenomena generated when a moving object penetrates through a suture line; and obtaining a wide-view-field and high-resolution panoramic spliced video with a good visual effect by using an improved fade-in and fade-out fusion algorithm. The steps are simple, and the spliced image with a good visual effect can be quickly obtained.

Description

technical field [0001] The invention relates to a video fusion algorithm, in particular to a video fusion algorithm based on a dynamic optimal suture line and an improved fade-in and fade-out method suitable for a multi-eye camera system, and belongs to the technical field of video information processing. Background technique [0002] Vision is the most effective means for human beings to obtain information. About 80% of the information that human beings receive every day is obtained through vision. In today's society, shooting equipment such as digital cameras, photography and video technologies have become a must for every family, and multimedia information such as video and images play an important role in monitoring security, intelligent driving, entertainment, remote sensing, military and many other fields. effect. At present, most of the video shooting equipment on the market can obtain a small field of view, which is far less than the field of view of the human eye, ...
