Application of VR computer image technology in 3D virtualization of sports human science

摘要

Compared with traditional geometric modeling techniques, image-based modeling technologyhas the advantages of simple operation, quick reconstruction, and strong sense of reality.Compared with the three-dimensional scanning technology, it has the characteristics of low costand simple algorithm. In a broad sense, the image-based 3D modeling technique not only includesthe geometric modeling of the entity but also includes visual restoration, ie, reconstruction ofthe geometric model of the entity using the image, and restoration of its corresponding surfacetexture, reflection properties, lighting conditions, and the like. This paper focuses on the applicationof geometric reconstruction methods to study the application of VR computer imagesin the three-dimensional virtualization of sports human science. By combining the backgrounddifference method and the interframe difference method, the target region where the movinghuman body is located can be accurately extracted from the video, and then the idea of the humanbody can be divided along the virtual plane. Finally, the end-point feature points of the humanbody are determined by the geodesic distance, and a three-dimensionalmodel skeleton is buriedusing a discrete penalty function, and an image-based three-dimensional reconstruction systemis realized.
