The invention relates to an urban vector road network registration method based on local control in a GIS-T, which belongs to the technical field of intelligent traffic data acquisition, and the method comprises the following steps: 1) extracting a center line of a road and gravity center points of settlement places on the sides of the road as control points; 2) establishing a Delaunay triangularmesh; and 3) carrying out affine transformation which corresponds to a triangle. The method obtains discrete points on the center line of the road and the gravity center points of the settlement places on the two sides by adopting the programming method on the basis of comprehensive consideration of advantages and disadvantages of various vector road network registration methods, and can realize planar subdivision by establishing the Delaunay triangular mesh, and reduce the registration error by limiting the registration of a road network diagram in a single triangle of the triangular mesh for carrying out; and the method has strong implementation and high precision, does not need to carry out a large amount of pretreatment on the diagram, and can reduce the cost of a system and the complexity degree of the design of the system and improve the performances of the system.
