Online Display And Virtual Test Drive System Of Expandable Light Truck

With fierce competition in the automobile industry,more and more automobile manufacturers have adopted network marketing to increase channels of information transmission.As a result,the profit of enterprise can be maximized.However,there is a problem in automobile network marking that how to exhibit the real performance of the car using appropriate human-computer interaction and how to acquire the client feedback timely.This paper takes light truck as an example,which creates an automobile virtual model and designs an online display and virtual test drive system of expandable light truck.As a result,the performance of different cars can be exhibit online,breaking through the limitation of time and space and improving the user experience effectively.Meanwhile,the automobile manufacturers can acquire the user information from this system.This paper creates a virtual car model based on the CAD model of automobile and the real automobile in the physical world,which can truly reflect the information of automobile exterior interior decoration modeling,size data,material parameters,paint color,configuration parameters,fuel consumption and acceleration performance performance.As a result,the information transmission between the physical world and the virtual world is realized,and the performance of the car to users in the virtual space is displayed visually and conventiently.On the basis of desktop,the paper studies three human-computer interaction modes,including the interaction of external steering wheel devices,kinect motion sensor devices and voice interaction,which are studied to meet the interactive needs of different scenarios of online marketing and offline exhibition,and effectively improve the user experience of online and offline car viewing.Online display includes 3D model display and image modeling display.At the same time,two ways of online presentation,including 3D model display and image model display are studied in the paper,so that consumers can have a more comprehensive understanding of the automobile.Based on Unity 3D design platform,this study uses 3DMAX software for 3D model building,Photoshop for interactive interface design,MySQL database for data storage,C#for online display and virtual test drive system of expandable light truck.The four functions of building system includes user information management.automobile 3D exhibition and feature selection,virtual driving,and driving result reporting.Concretely,the user information management module stores the user's basic information and feedback information to the database through the user's registration and login,so as to facilitate the enterprise staff to access customers.The automobile exhibition includes 3D interior and appearance display,panoram-like demonstration,video introduction,word introduction,voice introduction,voice interaction,etc.Auto online display and selection module includes auto 3D model interior appearance display,panoramic display,text introduction,voice introduction,video introduction,voice interaction,car model selection,car paint color selection,engine model and cargo selection and test drive scene selection and other functions.The virtual test drive module enables users to drive virtual cars in various interactive ways according to the virtual model and optional parameters.The test drive report module can provide users with a test drive report including test drive time,test drive mileage,fuel consumption performance,acceleration performance and test drive space.The system can show a variety of cars by adding virtual car models and builds a new platform for users to fully understand the characteristics and performance of the automobile,and increases the communication channels between automobile manufacturers and users.The feasibility of the system is verified by the actual application.
