| Abstract: | This paper describes the method for testing of tunnel portal.The method collected the 3D coordinate of the tunnel portal circle firstly.Then the 3D coordinate of the tunnel portal center was calculated.The data processing is divided into 3 steps as 3D plane fitting,coordinate transformation and flat circle fitting.An engineering example proves that this method is reliable and practical. |
