Abstract The relation between the local coordinate system can be solved and the practical 3D coordinate system with the 3D datum transform model, and then by using the relation between the center coordinate of shield tail and link can be obtained, finally,the coordinate of the center of shield head can be solved based on the center of link and the distance of jack. The results show satisfactory when it is used in shield guiding in practice.
Key words ：
3D datum transformation
