随着第四次全国文物普查的全面推进，古建筑的部件级建模技术成为古建筑数字化任务中的关键议题。针对传统单一数据源采集方法在古建筑三维建模中存在的局限性，提出了一种基于无人机倾斜摄影测量、三维激光扫描仪与手持式三维激光扫描仪的多源数据融合采集方法。通过实地应用验证，该方法能够全面获取古建筑的几何与纹理信息，有效提升建模精度和效率。针对实际古建筑的建模结果表明：多源数据融合采集方法可以充分发挥各类设备的优势，实现古建筑数字化保护的高精度要求。

With the comprehensive advancement of the Fourth National Cultural Relics Survey, the component-level modeling technology for ancient architecture has become a key issue in the digitization of historic buildings. Addressing the limitations of traditional single-source data acquisition methods in ancient architecture 3D modeling, a multi-source data fusion acquisition method based on UAV oblique photogrammetry, terrestrial laser scanning and handheld 3D laser scanning was proposed in this paper.Through practical application and verification, the geometric and texture information of ancient buildings can be comprehensively obtained by this method which effectively improves modeling accuracy and efficiency. The modeling results of actual ancient buildings demonstrate that the multi-source data fusion acquisition method can give full play to the advantages of various equipment types to achieve the high-precision requirements for digital preservation of ancient architecture.
