The method is a construction method of hierarchical detail models of conifer plant canopy. When the projection width of conifer in an image space is bigger than a pixel value, column models are used for describing conifer, and the column models are automatically processed by polygonization according to the distance so as to be expressed as prisms with different numbers of seamed edges.
