Abstract: The present invention discloses a method for splicing vector polygon regions with holes, comprising the steps of: acquiring any two vector polygon regions A1 and A2 to be spliced, the outer frame P1 of A1 and the outer frame P2 of A2; judging whether P1 and P2 have overlapping parts; storing the connection relationship of the non-overlapping edges and the non-overlapping edges of P1 and P2 in a data table T; performing intersection on the overlapping edges of P1 and P2 and storing the overlapping edges in the data table T; traversing the data table T, finding the connection relationship of edges, and constructing the splicing of vector polygon regions. According to the scheme, the present invention has the advantages of wide application range, high splicing efficiency and the like, and has high practical value and popularization value in the technical field of vector graphics splicing.
