| Abstract: | According to the mathematical definition of area objects,they were divided into 2 types such as simple and multiply connected object.The main skeleton of different kinds of area objects were extracted with the automatic extraction technology based on triangulation of Delaunay.The results showed that the algorithm had good extraction effect on main skeleton of area objects,and the interpolation results basically fitted to the requirement of interpolation. |
