【摘 要】三维数字模型可以模拟复原场地三维景观，提取场地信息，帮助风景园林师深化对场地的观察和理解。小型无人机。感具有成本低、灵活性高及时效快等特点。以南京城东羊山公园为实例，借助小型固定翼无人机和瑞士Pix4Dmapper软件，通过像控点采集，影像预处理，点云加密和点云滤波处理后，实现了公园三维实景数字模型的构建。结果表明，该方法获取的公园三维点云模型，点云密度较高，模型分辨率较清晰，细节表现丰富，可用于场地的景观展示及后续场地规划设计分析。%Three-dimensional digital model could simulate the landscape of three-dimensional space and extract site information, which could help landscape architects intensify observation and understanding of the site . Smal UAV remote sensing has many advantages such as low operation cost, high deployment flexibility, quick acquisition and so on. We took Yangshan park as the research site, located in Nanjing east. Employing the smal fixed-wing UAV and the Swiss Pix4Dmapper software, the data processing chain was presented, which included colecting GCPs, image pre-processing, point cloud densification and point cloud filtering. We evaluated accuracy of the real three-dimensional digital model of the park. Results showed that three-dimensional point cloud model achieved by this

method had high model resolution and rich in details, which could be used for site planning, landscape displaying and subsequent site design analyzing.
