SuperMap Underground Parking Lot Solution integrates map, positioning and navigation. The parking lot application based on this solution can solve the difficulty in parking, finding cars and car management in the indoor parking lot through the pipeline system of the PC client and the parking system of the mobile client. It is an economical, efficient and reliable mobile GIS application solution, which can be applied to underground parking lots of campuses, office buildings, high-speed railway stations, airports, communities, etc.
Nowadays, more underground parking lots are put into use, which alleviates parking difficulties in a way. However, underground parking is still faced with challenges such as inconspicuous marking, difficulty in parking and finding a car for vehicle owners, uneven parking space resources, lack of information between supply and demand, and low management efficiency. How to make reasonable use of parking space resources, keep abreast of parking space information, and help people to park and find their cars?
SuperMap mobile GIS products provide a parking lot intelligent car search solution. With the characteristics of 2D&3D integration, navigation GIS integration, virtual and reality integration, and indoor and outdoor integration, it integrates map collection and production, real-time location positioning, path analysis, and navigation. This solution will car owners to quickly find parking space and the car.
The Basis for Car Finding and Management: Parking Lot Maps
The parking lot map is the basis for car search and parking management, focusing on the display of small areas, large scales, high precision, and refined internal elements. SuperMap mobile GIS provides an integrated solution for map collection and editing and produces the parking lot navigation map through original data collection and data production.
We can make parking lot map data through SuperMap iDesktop/iDesktopX. There are various sources of parking lot maps, such as maps in CAD format, raster maps scanned from paper maps, maps in GIS format, and maps in BIM format, among which GIS format maps can be collected through SuperMap iTablet or purchased.
These maps of different formats can form a 2D&3D integrated underground parking lot map following the steps of attribute editing, style setting, stair setting, path editing, and coordinate system setting. When the POI, road network, etc. in the map change, it supports adding, deleting, and modifying directly on the mobile terminal, one-click editing, and real-time updating, which improves the map update efficiency and reduces the update cost.
In this map, different colors indicate free parking spaces, occupied parking spaces, reserved parking spaces, oversized parking spaces, charging pile parking spaces, etc. Users can preview the parking space map in the parking lot in real time, get an overview of the multi-floor parking lot, check the parking space status, and quickly find and confirm a suitable parking space.

High Accuracy and Performance: Parking Lot Location Positioning
Due to its own limitations, satellite positioning cannot be used in indoor or underground environments. Therefore, in the positioning of the underground parking lot, it is necessary to use indoor wireless positioning technology to assist to solve the problem of weak satellite signal and failure of penetrate the buidling when reaching the ground. Common indoor wireless positioning technologies include Wi-Fi, Bluetooth, infrared, ultra-wideband, RFID, ZigBee, ultrasonic, and AR positioning. SuperMap provides a variety of indoor positioning methods, commonly used are Bluetooth positioning and AR positioning.
1. Bluetooth positioning: It is necessary to deploy a Bluetooth transmitter, that is, a Bluetooth Beacon. After receiving a strong signal broadcast by the transmitter through a mobile phone, tablet, etc., we can determine the location of the mobile device in the room. The Bluetooth Beacon is powered by batteries. Powered by two AA batteries, the battery power of the Bluetooth Beacon can last for 3-4 years, and the positioning accuracy is 1-3 meters.
2. AR positioning: It is based on visual-inertial odometry positioning, which can accurately sense the movement of equipment in the room. There is no need to deploy additional hardware equipment or collect a number of fingerprints. The positioning accuracy can reach the decimeter level only by configuring the coordinate system of the indoor map. It not only ensures positioning accuracy, saves the cost of hardware deployment and maintenance, but also saves a lot of time and cost of location point acquisition.
The underground parking lot can adopt the method of the mobile terminal acceleration sensor and parking lot hardware equipment auxiliary calibration to complete the indoor positioning and navigation of vehicles. The acceleration sensor on the mobile end and the displacement cumulative correction algorithm on the software end are used to complete the real-time positioning of the vehicle between the junction nodes. Once the vehicle reaches the junction node, the junction positioning and calibration camera will take photos to identify the vehicle and calibrate the vehicle in real time according to the position of the camera to ensure the accuracy of positioning and navigation.
Intelligent navigation for car search in parking lot
Intelligent Car Search in the Parking Lot Supports both Driving and Walking
SuperMap mobile GIS has comprehensive functions, including a seamless connection between indoor map and outdoor map display, free switching of 2D and 3D maps; multi-floor display and free switching, free viewing of floor information; unlimited waypoint settings; path analysis and path navigation across floors; indoor path guidance, clear voice guidance.
When navigating in the parking lot, SuperMap mobile GIS indoor navigation provides two ways of driving and walking to find a parking space and a car. The user browses the parking lot map and selects the location where to park. People can navigate from the entrance to the selected parking space. After the parking, the current parking space information is recorded through real-time positioning, manual entry, QR code scanning of information points, and parking space probes. Then, people can turn on the walking navigation and navigate from the current parking space to the parking lot exits such as elevators and gates. After returning to the parking lot, people can turn on the walking navigation again to quickly find the parking space.
In addition to the above mobile terminal functions, a server management system can be built to support equipment status management, operation management, vehicle management, parking space management and data statistics query. In addition, it can be used for user management, such as monthly/yearly users, temporary users, and parking space users, and can pass through the green channel directly, saving parking time. It can also provide a pick-up buffer service. In underground parking lots with tidal characteristics, such as schools and office buildings, registered vehicles are oonly allowed to enter. After the camera at the entrance gate identifies the information, the vehicle enters the pick-up and check-in queue, which ensures the good order of car's management.
