The Design And Realization Of3D Indoor Map

People are always chasing for more convenient life, and this wish is graduallycoming true with the appearance of computer and the development of relatedcomputer technologies. Map software is so popular that it has become fledged patterncombining with the resources to position and with a variety of service supported bymega-data technology. The development of Indoor map is relatively later than that ofordinary map. Indoor map just get explosive growth around the year of2010.However, due to various reason, the indoor map didn’t achieve widespread use likenormal map. At home and aboard, many companies have tried various forms anddeveloped various types of products, showing the characteristics of diversificationand personalized.At present, the indoor map also combined with all kinds of emerging technology,continually expanding function and application field. Combined with various indoorpositioning technology, indoor map has more application fields. The typicalapplication scene is that in a large mall, providing information of nearby store andpreferential or bargain information, but can also navigate in indoor. However, indoormap application is far more than these, through a combination of the big datatechnology, the store can analyze customer’s demand and develop marketing strategyby using the data of a large number of customer’ stay time, route. After years ofcontinuous development, the application field has more and more applied intopeople’s life at the present than in the past when it is mostly applied into theproduction field. We can believe that the future that can be expected, the indoor mapstill has much development space. This paper is aiming to discuss an attempt andexperiment of indoor map. The indoor map, as a kind of map, using various geographic information mark asthe major function, but there are some differences between that and general map. Firstfrom the marking scale, indoor map marking scale was significantly smaller than thelatter, the scale of former is about a few meters, while the latter is about a dozen totens of meters. This increased of data quantity, on the other hand also increasedediting and maintenance work of Indoor map. In addition, the indoor map and thelatter also has the obvious difference in marker information. According to its specificuse scene, there are huge difference between them in the label content. Furthermore,there are huge different in vertical superposition of display content between theindoor map and the latter. Due to the existence of superposition in vertical directionof floors in multi-storey buildings and the presence of many vertical structure, therepresentation methods of map usually cause some confusion, which needrepresentation specifically designed for the indoor map. Finally, according to thespecific requirements, the indoor map may need more tracking updates. Stores inMALL need more frequent update. Depending on the exhibition of the museum, themotion trend and the architect layout need frequently change and so on, which haveincreased the difficulty and cost of maintenance. Maintenance method has greatdifference between indoor and general map. These differences in the presence of anindoor map, brings some obstacles to the development of the indoor map, on the otherhand also shows that, for the indoor map we still have more development space toattempt to.Compared with ordinary maps, the development of indoor map more depend oncommercial and public demand. Although the indoor map can bring convenience,because of its cartograph method is different from that of the general mappingmethod, it need much more time cost and the human cost. In addition, the indoor mapalso contain more information, has relatively short exploration history and data accumulation, which will increase the cost. For the reason above, currently indoormap exploitation basically target on large public facilities (airports, museums,libraries, schools), and large commercial or business premises (large mall, MALL,hospital, factory, office building). For the building that take the vast majorityproportion, residential construction, and mixed residential buildings and smallbusiness premises and public places, will probably not be in the eyes of the mapdeveloper in the next10years or even decades. This not only involve cost problem,but also involve the privacy and anti-terrorism issues.On the basis of a number of reasons, this paper take the target softwareapplication scene at fixed map display monitor in large MALL. Through appropriateextension, this application can also be used at a variety of map demand of other largebuildings, and run on the handheld terminal, but these are not in the scope of thispaper. This paper mainly focus on how to realize the indoor3D map, how toreasonably and effectively to combine, manage and display each data, and make apractice of the implementation of the path search in the3D indoor map.The realization of the indoor map, refer to the building that is located in JilinCity Fengman Economic Development Zone, opened in December28,2014, JilinEurasian commercial complex commercial building, Jilin Eurasian Commercialcomplex.This building have9floors in total, with the ground height of38meters, and7floors above ground and two underground floors.7floors above ground and B1as abusiness area, basement2as a parking lot. The mall has a total construction area of281868square meters. Jilin Eurasian commercial complex is a integrated shoppingand entertainment center in clothing, cosmetics, jewelry, food and beverage timeout,fitness and entertainment as a whole. And both banks, cinema, tea, wine, Coffee hall,beauty shop, hair salon, body shop, pharmacy, book bar, laundry, business negotiation, everywhere highlight the life function, strong affiliated cultural exchange functionand information collection function of Eurasian commercial complex.There are lots of realization methods of indoor map, according to detailedprocedure. The realization process of this paper uses the following tools from datacollection to the final programming implementation. This implement uses Photoshopin Image processing, and SketchUp as3D modeling tool, SQLite as the database, andusing SQLite Expert as the database management tools, programming in Unitycombined with the NGUI plugin for creating user interface. C#uses as mainprogramming language, there may involve a part of Javascript and a small amount ofruby.The realization of the process, we follow the steps and methods.1data collection: through a geographical survey to get the actual data, includingthe floor and store information.2collation of data: the establishment of model and the corresponding database.3Programming: including the structure of the program to the final realization ofideas.This paper will make detailed description the on some key points of datapreparation process and programming operation.
