Embodiment Construction

[0025] The present invention will be described in further detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0026] Aiming at stage scenes and large baseline camera array acquisition, this patent proposes an interactive free-viewpoint video guidance system and method based on virtual viewpoint synthesis, which makes free-viewpoint video guidance possible.

[0027] The present invention is based on the interactive free-viewpoint video guidance method based on virtual viewpoint synthesis, such as figure 2 As shown, it includes the following steps: S1: collect multi-viewpoint video; S2: match the collected multi-viewpoint video to obtain the "viewpoint + disparity map" video formed by each adjacent viewpoint and its corresponding disparity map; S3: according to the user Selectivel...

Abstract

The invention provides a free viewpoint video director method. The free viewpoint video director method comprises the following steps: S1, collecting a multi-view video; S2, matching and processing the collected multi-view video, and obtaining a ''viewpoint + parallax'' video formed by the adjacent viewpoint and the corresponding parallax image; S3, transmitting the ''viewpoint + parallax'' video to the user selectively according to the view point position of the user; S4, synthesizing a virtual viewpoint video according to the ''viewpoint + parallax'' video. The invention also provides a free viewpoint video director system based on the free viewpoint video director method mentioned above. According to the free viewpoint video director method and system provided by the invention, the virtual viewpoint video of arbitrary viewpoint can be synthesized through the video of ''view + parallax'' formed by the adjacent viewpoint and the corresponding parallax image, therefore, the video with free optional viewpoint can be provided to the user.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method for synthesizing virtual viewpoints, and an interactive free-viewpoint video guidance method and system based on virtual viewpoint synthesis. Background technique [0002] In traditional film and television and radio and television, the audience can only passively accept the shots taken by the photographer or directed by the director, and there are jumps in the position of the viewpoint and the video screen during the switching process of the angle of view or the shot, resulting in the audience lacking the presence of watching sense and experience. With the rapid development of multimedia display technology in recent years, especially the improvement of multimedia terminal processing capabilities, the improvement of the collection quality of multimedia information collection equipment, and the development of various display devices, free viewpoint video technology has emer...
