description The invention discloses a regular house roof automatic extraction method based on remote sensing image spectral information. Firstly, spectral value information of pixel points in a collection area is classified, edge points are searched, then under the limitation of the fitting degree, edge lines fit a plurality of straight lines, the edge lines intersect to generate corner points, if the corner points are edge points, the corner points are reserved and are connected pairwise to generate pseudo edge lines, the pseudo edge lines are divided into three types according to the attributes of the points on the pseudo edge lines, and the pseudo edge lines are divided into three types. The method comprises the following steps: for pseudo side line points of which the spectral values are within a roof prior spectral range and which are edge points, reserving the pseudo side lines, and dividing the pseudo side lines into two types according to the relation between the lengths and included angles of the pseudo side lin
