| Abstract: | Section of tunnel monitoring is an effective way to obtain the real deformation of tunnel. Through the high precision automatic measurement of segment and the ellipse fitting algorithm, the geometric parameters of ellipse of tunnel can be obtained. Considering effect of segment surface disruptors, process date error steps is added. Through the test of the engineering example, the algorithm can prove effective and reliable. |
