Abstract

The invention provides a three-dimensional building modeling method. The method comprises: house individual-floor individual-household graphs are read from a house property database, two-dimensional single-property-right body house fundamental planes are extracted from the house individual-floor individual-household graphs, and assignment of attribute values of the two-dimensional individual-property-right body house fundamental planes are carried out; according to the attribute values of the two-dimensional single-property-right body house fundamental planes, fundamental plane stretching is carried out to construct three-dimensional individual-property-right body houses; house combination is carried out on the three-dimensional individual-property-right body houses to construct a three-dimensional building model; a house table is read from the house property database, and house right state attributes are read according to the house table and assignment is carried out on the three-dimensional building model; and according to the corresponding right state attributes, display pattern rendering is carried out on the three-dimensional building model, a three-dimensional building model is outputted and applied. With the method, full utilization of the property graph information can be realized and the three-dimensional building model can be constructed rapidly, so that a defect of complicated building complex management by the two-dimensional building table can be overcome.

Description

technical field [0001] The invention relates to a method in the modeling field, in particular to a three-dimensional real estate modeling method. Background technique [0002] The unified registration of real estate has brought opportunities for the integration of real estate data. The difficulty of real estate data integration lies in the unified management of different dimensions of real estate data, that is, how to effectively manage two-dimensional land data and three-dimensional building and structure data in a unified manner. At present, in the pilot work of real estate unified registration that has been carried out, the data management method is still applied to the real estate management method, such as: the floor plan of the real estate and the hierarchical household diagram are stored as binary stream fields, and the role of real estate graphics is only for viewing. The use of data The rate is lower than that in the form of maps used in cadastral data management. ...
