Research On Texture Reconstruction Of 3D Model Surface Based On Multi View Images

With the development of society and the advancement of science and technology,virtual reality has gradually entered people's lives.As an important research direction of virtual reality,3D reconstruction has attracted a large number of scholars to study and research it.At present,the realism of graphics is still the research difficulty of 3D reconstruction technology.Mapping the image captured by the camera to the surface of the 3D model with texture mapping to add texture information to it is one of the effective methods to solve the above difficulties.This method is the 3D model surface texture reconstruction technology studied in this paper.The texture reconstruction technology can effectively enhance the detailed features of the 3D model surface without increasing its geometric complexity,and can greatly improve the reality of the 3D model reconstruction.It is widely used in various fields.Therefore,the main research contents of this subject are as follows.The main research cont ent of this subject is based on the texture reconstruction of the 3D model surface in a large indoor scene,so it is difficult to achieve full coverage of the reconstructed area using a texture image.Therefore,multiple guns need to be used to simultaneou sly capture images from multiple perspectives in an indoor scene,then stitch and fuse to generate an indoor panoramic image,and finally use the panoramic image for texture reconstruction.Using this method can realize the surface texture reconstruction o f 3D model based on multi-view images in large scenes,and can get better reconstruction effect.This article first studies in-depth research on mainstream texture reconstruction algorithms and implements it in the experimental environment of this topic.Aiming at the texture distortion stretching,texture distortion,texture loss,texture map and 3D geometry existing in indoor large scenes model features do not match.The method is improved by inserting layers inside the 3D geometric model and adding perspective projection transformation to the texture reconstruction algorithm.The perspective projection transformation can transform the texture image from the camera's frustum space into a real three-dimensional space,so that the texture image restores its own depth information,and then combined with the layer's sense of suspension,it can present a highly realistic t he three-dimensional scene is more in line with the visual experience.Finally,the OSG three-dimensional rendering engine was used in combina tion with Open CV and Open GL,and the C ++programming language was used to implement it,and the practicability was verified.The experimental results show that the improved method effectively solves the above problems,greatly enhances the authenticity o f the 3D reconstruction model,and can obtain better texture reconstruction effects.Moreover,the method in this paper greatly improves the efficiency of texture mapping.Reduces texture reconstruction time and also consumes less system resources.
