| Abstract: | According to the one-dimensional direct linear transformation,this paper proposes the inverse one-dimensional direct transformation formula and its solution method,and then uses a single digital image to obtain the height of buildings by the inverse one-dimensional direct linear transformation formula,which can provide the basis for three-dimensional data for the digital city construction.Finally,the feasibility of the algorithm has been verified by experiment. |
