Abstract:In order to solve the problems of poor noise suppression ability, easy hole defect, poor reproduction quality of cultural relics and lack of detail, a digital museum relic image reproduction simulation system is designed. Visual C++ and VTK are used as the system design platform, and the connection between the 3D reconstruction IP core and the MicroBlaze software is completed by using the FSL bus, and the system hardware structure diagram is designed. A clustering idea is introduced to filter out small-scale noise through a point cloud bilateral filter. The hole phenomenon in the process of triangulation of point cloud data is filled. The B-spline function least squares method is used to fit the surface. The two-dimensional texture coordinates are established by UV mapping, and the image texture is mapped to the surface mesh to realize the three-dimensional reconstruction of the cultural relics image. The results show that the design system shows the result with realistic detail texture; the obtained three-dimensional reconstruction results have better information entropy, average gradient, signal-to-noise ratio and equivalent coefficient.
