Abstract: A 3D reconstruction system is developed with VTK and MC.Since rendering or storage cost of object is proportional to the number of triangles in mesh,too complex and detailed model will cause system overload in storage,transmission,computing and real-time rendering of mesh.Merging vertexes can reduce the number of triangles in mesh and hash mapping of the mesh can reduce over-duplicated storage of vertexes.

摘要: 使用VTK工具包和MC重建算法开发了一套医学影像三维重建系统,并着重对实时性进行研究。由于重建后图像数据的处理时间和存储代价与三角形网格中三角形数量成正比,过于复杂和细节化的网格会给图像数据的存储、传输、计算和实时绘制等带来负担,故采用了顶点合并的三角形网格简化方法来减少三角形数量。另外,网格存储中存在公共顶点的大量重复存储,故提出了三角形网格的哈希映射存储方法,消除了顶点的重复存储。
