摘　　要：工程岩体稳定性主要受节理发育特征控制,岩体节理信息提取与分析对于工程设计、地质工程评价和施工安全具有重要意义。针对当前岩体节理信息提取存在工作量大、劳动强度高、作业风险性强且效率低的问题,提出了一种基于多旋翼飞控平台区域岩体节理信息提取方法。分析了系统的软硬件组成,阐述了无人机航拍调查、区域岩体环境三维虚拟重构、节理裂隙信息提取等数据处理流程,并分析总结了多旋翼无人机开展节理岩体数据采集、基于航拍视频的节理岩体模型虚拟重构、岩体节理信息提取与分析3项关键技术,同时验证了系统的精度。依托黑沟矿区露天边坡节理裂隙调查工作进行了技术验证,现场试验表明:所提出的节理裂隙信息提取方法操作简便、准确度高,为快速提取岩体节理信息提供了参考。The stability of engineering rock mass is mainly controlled by the characteristics of joints.The extraction and analysis of rock mass joint information are of great significance to engineering design,geological engineering evaluation and construction safety. Aiming at the problems of a large workload,high labor intensity,high operational risk,and low efficiency in current rock joint information extraction,a technique for extracting regional rock joint information based on multi-rotor flight control platforms is proposed. The software and hardware components of the system are analyzed,the data processing flows of UAV aerial survey,three-dimensional virtual reconstruction of regional rock mass environment,and joint information extraction are discussed,besides that,three key technologies of multi-rotor UAV for joint rock mass data acquisition,virtual reconstruction of joint rock mass model based on aerial video,and extraction and analysis of joint information are analyzed and summarized.At the same time,the accuracy of the system is verified.Based on the investigation of joint and fissure of slope in Heigou mining area,the technical verification is carried out.The field test results show that the method of extracting joint information proposed in this paper has the advantages of simple operation and high accuracy,which provides a reference for rapid extraction of rock mass joint information.
