Research On Automobile Design Method Based On Modeling Image

As domestic auto industry is developing continuously,more and more companies started to study the self-owned brand.Nowadays,every auto company's technical gap is gradually reduced,the modeling of the appearance of the car is particularly important.Car modeling is an important part in the process of car design,when excellent car modeling program brings aesthetic experience to people,it also shows the vehicle brand's culture and genes.Excellent car shape needs to satisfy the market positioning and user's needs.The results of each series of vehicles will determine the value of their final creation.Along with the development of auto design,the relevant car modeling theory is constantly improved.Excellent car modeling methods can help designers more easily to integrate the vehicle gene,corporate culture and market demand into the modeling process.What is more important is that the excellent car modeling method can through a complete series processes to output excellent car design's results.This paper studies the image of automobile modeling from the view of semantics,combines the semantic difference scale with the automobile modeling,and deduces the automobile modeling method which is suitable for the automobile car stylist.Firstly,this paper sorted out the study results from two existing aspects of semantic and car modeling.It emphisises on analyzing the design plan which combines semantic with automotive modeling design.Through sorting and summarizing,this paper finds that the research method of automobile design method is lack in the art field,and most of the methods are not suitable for the use of art car stylist.Based on the existing research results,this paper summarizes the advantages and disadvantages of various forms of knowledge expression,puts forward to take mapping model with the semantic difference scale data as the input and take the heat map of auto modeling's key point as the output.Taking the side shape of SUV as the research object,the semantic difference scale was used to collect the semantic data of automobile modeling,and the data of key points of automobile modeling were collected by CAD method.Establishing the mapping model of the two sets of databases,completing the output of the heat map.Finally,the model of automobile modeling based on this model is proposed,and the new car development is simulated to verify the validity of the model.That means inputting the expectations of modeling in the input,through the model mapping to get hot spots,and through the help of the hot map to complete the modeling program.Thenstudying the modeling plan with the method of semantic difference scale,check the study results whether satisfy the shape expectations or not.If the expectation is fulfilled,the method is proved to be valid.If it is not meet,then continuing to modify the model,improve the design method.
