摘　　要：徽州廊桥是祖先留给人类社会的宝贵财富,其数字化展示与传承一直是社会广泛关注的热点.但目前的数字化展示效果与真实建筑差距较大,难以还原其历史、文化与艺术价值.为更好更真实地展现徽州廊桥的空间数字化展示效果,研究首先运用多源数据融合技术获取与处理数据.并从粗配准与精细配准两个角度设计采样一致性初始配准优化算法与迭代最近点优化算法,由此可得基于三维建模的多源数据融合优化(optimization algorithm for multi-source data fusion based on 3D modeling,3D-MFO)算法.研究结果表明,在廊桥、村落与树木三组数据的配准全过程中,3D-MFO算法的耗时分别为48 s、76 s与138 s.在徽州廊桥建模展示后,超过80%的观赏者对该数字化展示表示满意.综上所述,研究提出的3D-MFO算法具有较好的性能与应用效果,有利于徽州廊桥的数字化展示与推广.Huizhou corridor bridge is a precious treasure left by its ancestors to human society,and its digital display and inheritance have always been a hot topic of widespread concern in society.However,there is a significant gap between the current digital display effect and real architecture,making it difficult to restore its historical,cultural,and artistic value.To better and more realistically display the spatial digital display effect of Huizhou corridor bridges,the study first uses multi-source data fusion technology to obtain and process data.And from the perspectives of coarse registration and fine registration,the sampling consistency initial registration algorithm and iterative nearest point optimization algorithm are designed and improved,thus obtaining the optimization algorithm for multi-source data fusion based on 3D modeling(3D-MFO).The research results indicate that the 3D-MFO algorithm takes 48 seconds,76 seconds,and 138 seconds in the entire registration process of three sets of data:bridges,villages,and trees.After the modeling and display of the Huizhou corridor bridge,over 80%of viewers express their satisfaction with the digital display.In summary,the proposed 3D-MFO algorithm has good performance and application effects,which is beneficial for the digital display and promotion of Huizhou corridor bridges.
