摘要
针对传统基坑监测方法安全性低、耗时长,效率低,不能及时反映基坑边坡变形情况,该文提出了使用近景摄影测量技术进行基坑监测的一种全新方法,该方法实现了无接触测量,不仅工作强度低、安全方便、效率高,同时可快速获取任何空间点的三维坐标,通过实测数据验证了该方法的技术可行性和精度可靠性。
Because the traditional foundation pit monitoring method is a time-consuming,low efficiency and inefficient,it cannot reflect the deformation of foundation pit slope in time. This paper presents a new method for foundation pit monitoring using photogrammetry technology. The method realizes the non-contact measurement,which not only has low work intensity,safety and convenience operation,and high efficiency,but also can quickly acquire the 3 D coordinates of any point of any spatial point. The measured data validates the technical feasibility and accuracy of the method.
