Research on Landscape Feature Extraction of Urban Parks Based on Digital 3D Scanning Technology

为了提高城市公园景观建筑结构的特征提取精度,本研究基于三维测量技术,提出了一种采用贴近摄影测量的建筑景观特征提取方法。该方法通过无人机对目标建筑进行了三维测量,并利用线性特征提取技术,提取了建筑结构特征。结果显示,该研究设计的建筑结构特征提取技术可有效提取景观建筑结构中的飞檐等特殊结构特征,并可根据特征提取结构,区分不同的建筑区域。

In order to improve the feature extraction accuracy of architectural structures in urban park landscapes,this study proposes a feature extraction method for architectural landscapes using close photogrammetry based on 3D measurement technology.The method carried out 3D measurements of the target building by UAV,and extracted the architectural structure features by using the linear feature extraction technique.The results show that the architectural structural feature extraction technique designed in the study can effectively extract special structural features such as flying eaves in the landscape architectural structure,and can distinguish different architectural areas according to the feature extraction structure.
