Application of multi-source heterogeneous point cloud fusion technology in ancient building information preservation

doi:10.13474/j.cnki.11-2246.2020.0307

Abstract

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.

Key words: ancient architecture, 3D laser scanning, low-altitude aerial photogrammetry, multi-source heterogeneous point cloud fusion, information retention
