| Abstract: | Adoption Direct Linear Transform(DLT) method analyses and resolves stereo pair which gathered by general digital camera,accordingly obtains the surface three-dimensional space coordinate.Then the Triangulated Irregular Net(TIN) can be created by the surface three-dimensional space coordinates.Consequently the contour can be drawled up based on the TIN. |
