Automatic recognition method of doors and windows fan area based on convex hull algorithm

Abstract

Abstract:In the computer aided design of doors and windows, the computer only accurate positioning of fan region in the original frame position to further the design of the plastic window. Based on the design software of a door and window, the concept of convex hull in computational geometry is applied to identify the fan regions in the design of plastic steel doors and windows. The convex hull algorithm is used to analyze the frame coordinates to form a convex hull.Using Delaunay triangulation algorithm for convex hull analysis all triangle region The triangulation network is analyzed and merged, and all the fan regions are finally obtained. The convex hull algorithm can overcome the traditional plastic window cannot identify shaped window design software fan area faults, thus greatly expand the scope of design software.

Open-source Architecture and Development Application of Door and Window Parameterized Design System

“…Our enterprises need for rapid design of window type, window type and reduce the repeated design process planning design dimensions necessary and relevant design information. [2] In order to reduce the cost of the enterprise in the design and production, shorten the product design cycle, parametric design and manage-men t of product repetitive features are imperative. At present, computer-aided design is widely used in various companies.…”
