Study On The Comparison And Selection Of Decoration Design Program Based On Grey Relational Analysis And BIM Technology

With the increasing level of the material living standards,people's pursuit of spiritual life is getting higher and higher,the quality requirements of their living environment requirements are also getting higher and higher.The phenomenon that “The sound of an electric drill,hammer,saw,sound sound pleasant;single households,large house,small house,household decoration” shows that people's enthusiasm for decoration is increasing.With the rise of“home decoration” heat,the quality requirements of people on the decoration design are also increasingly high.Currently,the interior decoration design mostly exists that you can not see what you want,the display of the program is two-dimensional graph,users and designers have the deviation of comprehension,causing a large number of decoration regret and decoration disputes between designers and users,the resource waste and environmental pollution of secondary decoration causing of the completed decoration program,Building Information Model is a milestone in the field of construction,it not just can realize the transition from two-dimensional graph to three-dimensional stereoscopic space graph,but also the visualization three-dimensional display of Building Information Model on decoration program design combined with Augmented Reality technology can allow users to virtual roaming in the decoration program,enhance the users' understanding of the renovation program,and meet the individual needs of users.Therefore,with the improvement of people's living standard,researches on the 3D visualization dynamic display of the decoration design and the scientific choice of design scheme become more and more urgent.Based on this,this paper is based on a large number of documents and related data,the main research is as follows:First of all,this paper puts forward some problems on decoration design program,and elaborates the research background and significance,determines the main contents of this paper and the framework based on the present research.Secondly,the following theories are introduced in detail: Building Information Model technology,Augmented Reality technology and relevant evaluation methods.Again,the use of Revit software builds the decoration design program model combined with AR technology to show the program.Finally,referring to the relevant literature and related books and standard,the evaluation index system of decoration scheme is established,and the grey correlation model is established to compare the scheme.The paper selects an actual case of the train case and decoration scheme with grey correlation model is established by analyzing the case,we finally choose the best decoration scheme,to verify the feasibility of the scheme and the applicability of the method.In short,the BIM technology,Augmented Reality technology and grey relational analysis is introduced into the selection of decoration design,this can not only meet the experience of 3D visualization and concretization of the decoration scheme for users,and reduce decoration disputes and decoration regret,and by means of quantitative analysis can help users make scientific decisions,in order to make the decoration scheme more scientific and reasonable explore a new way of thinking.
