Construction And Application Of Indoor Map Model For Parking Guidance

At present,with the rapid development of economic,the pace of car into families continues to accelerate.And the Urban commercial center group has been diversified,and car shopping is also expanding.The demand for parking spaces from customer is growing.In order to meet the growing demand for parking spaces,the modern indoor parking has development to maximization,multi-storey,multiple parking spaces.However,the large parking lot has complex terrain,the empty spaces are hard to find,and the line is not clear.That causes that it is difficult to find a suitable parking space in a short time.At the same time,the lack of indoor parking related app is becoming serious.Parking dfficult problem has become a prominent issue in the city's commercial center.The reason why the existing technology or application of parking guidance is not perfect,the key issue is the map modeling of the indoor parking lot.The map thematic data system of indoor parking lot is not perfect,the level is not clear enough,the standardization production process of the map is not mature,and the lack of the integration of static information and real-time dynamic information is getting serious.It is not conducive to the realization of parking related services when there is no strong parking data system to support.However,the relevant research of indoor GIS is more mature,but thematic map for parking based on real-time parking is still relatively rare,and the thecnological process of thematic map is not yet perfect and is lacking of relevant technical support.Therefore,aiming at these problems,we design a thematic map model of indoor parking lot based on parking guidance which can solve the parking difficult problem effectively.Based on the analysis of characteristic of indoor parking lot and the demand for parking spaces from customer,we design a thematic map model of indoor parking lot based on parking guidance.The thematic map is no longer based on single app lication,it is designed based the combination of the specific characteristics of the indoor parking lot map elements as well as the demand for parking guidance.it includes the basic elements of the parking space information,multi layer navigation data,the information of the parking recommendation,positioning field information.The thematic map of indoor parking lot can be used in multi tier,multi floor,diversified parking map display,multi storey indoor navigation,and real-time path planning and other parking guidance related applications.To a certain extent,it can solve the problem of "parking difficulty".Meanwhile,we design a complete thecnological process of the thematic map which includes layer digitizing,automatic correction of layer,construction of navigation data,and the construction of parking space recommend.It makes up the lack of thecnological process.Besides,we design a modeling tool to improve the speed and accuracy of the thematic map making.The modeling tool is an plugin of ArcMap,which is easy to install and easy to operate and can help users to automate the process of making thematic maps.In order to verify the validity of the designed map model,we realize the indoor navigation of parking lot based on the navigation data,also we realize the real-time parking space recommond based on parking recommend data.At the same time,the experimental results are demonstrated.
