The Research Of 3D Reconstruction Based On Image Texture Information

The technology of 3D reconstruction is an important research direction in the field of computer vision.It can meet the needs of digital storage,computing,analysis and reproduction of realistic scenes and has considerable research value because of its ability to provide the function about scene visualization and virtual reality.The method of reconstructing objects or scenes based on images has become a hotspot in the field of 3D reconstruction because of its advantages such as low cost,simple operation and strong realism.The application scope and realism of the 3D model reconstruction method have been the goal of 3D reconstruction technology,and it is an important research topic in the field of computer vision.To solve these problems,the method of 3D reconstruction based on image texture information is designed and implemented.The method of detecting the vanishing point from the image texture information is proposed and the method of texture restoration of object surface based on texture element is proposed,which improve applicability of the vanishing point detection and the effect of three-dimensional reconstruction.In the realization of the vanishing point detection method,the implicit 3D structure information in the image of regular texture element is analyzed,and the vanish point calculation is carried out by using the straight fitting of the texture element to enlarge the range of the image for vanishing detection.In the process of recovering the texture of object surface,the segmentation of the two-dimensional image based on the texture element is proposed,the partial image of the best texture element is searched for image splicing,and then the texture mapping is carried out by using the perspective transformation method,which effectively reduces shape deformation,jagged fuzzy and so on,on the surface of 3D model texture,and significantly improves the effect of model recovery.The results of 3D reconstruction experiment based on image texture information show that it is feasible to calculate the vanishing point and implement the model reconstruction by regular texture element,and the texture recovery method based on texture element can recover the texture of strong realism and high quality on the surface of 3D model.
