摘　　要：介绍了旋转多基线数字近景摄影测量系统的技术特点和具体的实施方案,提出了基于旋转多基线交向摄影方式进行一种无需二次控制的、非接触的、快速便捷的滑坡监测方法.通过对滑坡监测的关键流程阐述及现场试验,分析了不同摄站数、基高比和交会角对其精度的影响规律,实验证明了该方法的可行性,精度可以达到毫米级.Briefly describes the technical characteristics of rotating multi-baseline digital close-range pho- togrammetry system and a specific implementation plan in this paper, and proposed a no secondary control, non-contact, fast and convenient for landslide monitoring method based on rotating multi-baseline Intersect the direction of photography. By describing key processes for landsiide monitoring and field test, we can analyzed the impact of different photo station number, the base-height ratio and tile contact angle on the aeeucacy. The experiment proved the feasibility of the method and the accuracy can reach a millimeter.
