The general attribute modeling methods of these two modes, once the known attribute boundary information is relatively large and complex, such as containing thousands of known attribute drilling boundary information sets and dozens or even hundreds of different attributes and these attributes are When the space is interleaved and distributed, it will lead to a large amount of human-computer interaction workload in the early stage, or even a human-computer interaction workload that is almost trapped in an endless loop.

Abstract
The invention discloses an uncertainty probability field attribute distribution modeling method and system. The modeling method comprises the following steps that (1) on the basis of known attribute boundary information, a whole space required to perform attribute space distribution modeling is subjected to geometric space modeling and description, and a whole field space is built; the second to eight steps are omitted; (9) an attribute boundary point set with the maximum probability in each type of attribute is subjected to vectorization; two-dimensional and three-dimensional vectorization boundaries of each type of attribute are obtained; an uncertainty probability field attribute distribution model is generated, and the like. The invention provides the modeling method and system with the advantages that on the basis of the known attribute boundary information, a unified distribution probability field of different attributes in the region space is built; then, the space distribution boundary of the complicated attributes in an attribute space body is automatically determined through the maximum probability of the unified distribution probability field; finally, different attribute space distribution is calculated through space vectorization iteration.
