Research And Implement On Indoor Space Information Visualization

Large data boom accelerated the development of visualization technology and get more attention,and the visualization technology gets rapid development.However,the development of indoor spatial information visualization technology is lagging behind.Compared with the outdoor space,indoor space has features like micro-space,high sensitivity to the scale,which can not use technology used in outdoor space.Although there are many kinds of indoor spatial information visualization technology including indoor GIS technology,virtual reality,image recognition and so on,there are many problems such as single application scene,complex use,high cost,weak stability and poor universality.Based on the problems above,this paper presents a new visualization system of indoor spatial information,which is based on the common indoor spatial plane map,and builds a set of indoor spatial map editing tools based on system definition and algorithm design.The system can draw personalized vector indoor space electronic map,and can be further excavated JSON structure data containing the indoor space information.Compared with other technologies,the system has advantages of a lightweight painting tool,drawing process cloud storage,drawing elements can be searched,drawing results can be excavated and other features.The design and implementation of the system makes the visualization of indoor spatial information data easy to achieve,and can help other technical research.The tool take a large-scale shopping center indoor space plane electronic map as an input,and successfully developed a web-based application,through the result of the indoor space map using the application,shows that the system has advantages of simple to use,low cost,versatility,high accuracy,and high reusability.
