摘　　要：血管三维模型是诊断心血管疾病的重要辅助参考,但表面存在的较多噪声会对诊断产生一定影响,需进行网格平滑。根据现有网格平滑算法,保留清晰特征和减小体积收缩仍具有挑战性。因此,本文提出一种组合平滑算法,并将其应用于人体不同组织结构的三维模型中进行验证。结果表明:该算法结合曲面重建与联合双边滤波,可实现去除噪声,并保持特征,减轻收缩。Three-dimensional vascular model is an important auxiliary reference for the diagnosis of cardiovascular diseases, but the surface noise will have a certain impact on the diagnosis, and grid smoothing is needed.According to existing mesh smoothing algorithms, it is still challenging to retain clear features and reduce volume shrinkage.Therefore, a combinatorial smoothing algorithm is proposed in this paper, and it is applied to the three-dimensional models of different human tissue structures for verification.The results show that the algorithm can achieve noise removal, feature preservation and shrinkage reduction by combining surface reconstruction and bilateral filtering.
