摘要
传统危岩监测方法存在效率低下、数据不全面等弊端,且单一倾斜摄影技术无法满足全面数据采集的高标准要求。鉴于此,提出了一种融合实景三维与站式三维点云数据的空地多源数据融合技术。利用该技术成功构建了高精度三维模型,并在此基础上进行了落石解译关键特征提取和岩壁落石运动的模拟分析。结合公园建设的实际需求,提出了针对性的落石防护措施。结果表明,精细三维模型可显著提升岩壁细节特征识别能力,为落石解译关键特征提取和危岩落石运动特性分析提供精确数据支持。研究成果不仅提升了危岩监测的自动化水平和精确度,而且为相关领域的研究和实践提供了技术参考。
The traditional monitoring methods for dangerous rock have drawbacks such as low efficiency and incomplete data,and the single-source oblique photography technique cannot meet the high standards of comprehensive data collection.To address these problems,we proposed an air-ground multi-source data fusion technology integrating 3D real scene and station-based point cloud data.Utilizing this technology,we successfully constructed high-precision 3D models and further conducted extraction of key features for rockfall interpretation and simulation analysis of rockfall motion on the rock walls.Considering the practical needs of park construction,we proposed targeted protective measures.The results indicate that the fine 3Dmodels significantly enhance the ability of recognizing detailed features of the rock walls,providing accurate data support for the key features extraction of rockfall interpretation and the movement feature analysis of dangerous rocks.The findings of this study not only improve the automation level and accuracy of dangerous rock monitoring,but also offer new technical references for research and practice in the related fields.
