The invention discloses an aerial photograph non-stereoscopic collection mapping method which comprises the following steps: taking image data (stereo image pairs), camera parameters, elements of exterior orientation and DSM data as input data; forming at least two display windows (namely a left window and a right window); respectively loading the stereo image pairs in the left window and the right window (namely a left image and a right image); drawing a roof polygon pgn1 on the left window, and querying the DSM data so as to obtain the Z coordinate value of each vertex of the pgn1; converting each vertex coordinate of the pgn1 into geodetic coordinates by virtue of a collinearity equation and a Z value, thereby obtaining a polygon PGN under the geodetic coordinate system, and converting the PGN into the right image by virtue of the collinearity equation, thereby obtaining a polygon pgn2; visually inspecting whether the pgn2 is matched with the roof in the right image by an operator, if not, moving the vertex coordinate of the pgn2 so as to be matched with the roof; and calculating to obtain the corresponding result polygon under the geodetic coordinates by virtue of the pgn1 and pgn2 according to the forward intersection principle after matching. The method disclosed by the invention has the advantages of high precision and high operating efficiency.
