| 摘 要： | 针对单一测绘手段难以获取古建筑表面完整空间信息的问题，本文提出了采用多源异构点云融合技术实现古建筑完整空间信息留存的方法。该方法首先采用由整体到局部的扫描策略实现古建筑主体激光点云数据采集，然后采用低空航空摄影测量技术完成扫描盲区的影像数据采集，最后基于光束法平差理论完成点云数据生产，实现了多源异构点云数据融合。试验表明，该方法能够满足古建筑信息留存的需要，在古建筑保护领域具有较好的推广和借鉴价值。

| Abstract: | Multi-source heterogeneous point cloud fusion technology is proposed in this paper, aiming at solvingthe problem that it is difficult to obtain the complete spatial information of the ancient building. This method first uses the whole-to-local scanning strategy to realize the 3D point cloud data collection. The low-altitude aerial photogrammetry technology is used to complete the scan of the blind zone image data collection. Data production has realized multi-source heterogeneous point cloud data fusion. Experiment shows that this method can well meet the needs of retaining digital information of ancient buildings, and has a good promotion and reference value in the field of ancient building protection. |
