Abstract

In this paper we propose a new method for convergence measurement of tunnel. We achieve this using Electro-optical distance meter and Image processing technology. Image processing make possible to calculate correct point of target in tunnel automatically. And we can get 3-D information of target positions easily by personal computer. In experiment we verified possibilities of this method, and usefulness of user-interface of this system.
