针对传统边坡地质灾害调查存在效率低下、人员危险性高、野外时间长等不足，利用地面三维激光扫描技术方法，采集沿黄公路3处典型地质灾害隐患点的两期三维数据，研究三维激光扫描监测地质灾害隐患点的可行性，并且利用纹理映射技术实现地质灾害隐患点的实际状况数字化存档。两期三维数据对比分析的结果表明，三维监测成果的精度与原始点云密度及点间距息息相关，地面三维扫描技术相对于传统方法能够获取更加全面的监测数据，可以在精度需求较高的地质灾害调查与监测领域推广应用。

In view of the disadvantages of the traditional slope geological hazard investigation, such as low efficiency, high risk of personnel and long outfield time, this paper uses the ground 3 D laser scanning to collect 3 D data of three geological hazard hidden points on the Road along the Yellow River in two phasets, studies the feasibiling of 3 D laser scanning monitoring geological hazard hidden points, and uses texture mapping technology to realize the actual condition of geological hazard point digital archive. The results of the comparative analysis of the two phases of 3 D data showed that the precision of the 3 D monitoring results is closely related to the original point cloud density and point spacing, the 3 D scanning technology compared with traditional method can obtain more comprehensive monitoring data, which can be popularized and applied in the field of geological disaster investigation and monitoring with high precision.
