    摘要:

    为了解决传统系统噪声抑制能力差、容易出现孔洞缺失、文物图像再现质量差、细节不丰富等问题,设计了一种数字博物馆文物图像真实性再现仿真系统。将Visual C++和VTK当成系统设计平台,利用FSL总线完成对三维重建IP核与MicroBlaze软件间的连接,设计系统硬件结构图。引入聚类思想,通过点云双边滤波器滤除小尺度噪声。针对点云数据三角剖分过程中的孔洞现象进行填补处理。选用B样条函数最小二乘法进行曲面拟合,通过UV映射建立二维纹理坐标,把图像纹理映射至曲面网格,实现文物图像三维重建。结果发现:设计系统展示结果有逼真的细节纹理;得到的三维重建结果信息熵、平均梯度、信噪比和等效系数均较优。

    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.
