Description
Technical Field
[0001] The present invention relates to the technical field of positioning and navigation, and in particular to an underground parking navigation system and method. Background Art
[0002] An underground parking lot refers to a building built underground for parking various sizes of motor vehicles. It is mainly composed of parking spaces, passages, ramps or mechanical lifting rooms, entrances and exits, and shunting yards. With the improvement of my country's economic level, more and more people choose to buy vehicles in order to meet the convenience of travel. However, due to urban development and increasing population density, there is less and less idle land in the city. Traditional ground and underground parking lots can no longer meet the needs of the increasing number of vehicles, so "difficulty in parking" has become a major problem for urban travel.
[0003] Chinese Patent Authorization Publication No. CN 108734990 A discloses an underground parking lot navigation system and method. The system includes a user terminal and a satellite navigation positioning enhancement system. After the user terminal enters the target underground parking lot, if the user terminal cannot obtain a satellite signal, the user terminal connects to the satellite navigation positioning enhancement system and obtains a satellite navigation signal from the satellite navigation positioning enhancement system. The user terminal determines the user terminal's real-time location based on the satellite navigation signal. The user terminal generates and displays the user terminal's real-time location within the target underground parking lot, or generates and displays a navigation path for the user terminal to the target parking space, until the user terminal arrives at the target parking space. When the user returns to the parking lot to retrieve the car, they operate the car search function on the user terminal. The embodiments of the present invention overcome the defect in the prior art that users need to manually download a parking-specific app and parking data when navigating in an underground parking lot, thereby achieving rapid positioning and navigation for users in underground parking lots.
[0004] The above-mentioned existing technical solutions have the following shortcomings: during use, the above-mentioned technical solutions can achieve basic navigation purposes, but lack real-time dynamic data support, which is inconvenient for real-time parking space status monitoring and dynamic path optimization and adjustment, and has certain optimization space. Therefore, it is necessary to design an underground parking navigation system and method to solve the above-mentioned problems. Summary of the Invention
[0005] The purpose of the present invention is to provide an underground parking navigation system and method to solve the problems raised in the above background technology, such as lack of real-time dynamic data support, inconvenience in real-time parking space status monitoring and dynamic path optimization and adjustment.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: an underground parking navigation system, comprising a user terminal and an indoor map system, wherein the indoor map system is placed in a target underground parking lot; After entering the target underground parking lot, the user terminal queries the vacant parking space information from the indoor map system, including the parking space number, location and distance, etc. According to the starting point of the user terminal and the target parking space, the indoor map system plans the optimal navigation path.
[0007] During use, it can effectively solve the problems of difficulty in parking and finding parking spaces in underground parking lots. Through docking with the indoor map system, real-time location perception and correction, intuitive navigation presentation and other functions, the indoor map system provides navigation path planning and navigation function implementation, and combines parking space input information to achieve efficient and accurate parking navigation services, providing users with convenient and efficient parking navigation services, improving users' parking experience in underground parking lots, and reducing the time spent looking for parking spaces.
[0008] Furthermore, the indoor map system includes a parking space information input module, which is responsible for collecting and updating parking space status information, including parking space number, location and occupancy status.
[0009] When the parking space information input module based on the above-mentioned indoor map system is used, the latest available parking spaces can be viewed through the user terminal and directly navigated to the target location. The system guides vehicle diversion based on real-time data to avoid congestion, thereby reducing the need for manual inspections, reducing operating costs, and enhancing user experience. That is, by automatically detecting parking space occupancy, the lag of traditional manual inspections or static maps is avoided. At the same time, when the user enters the target parking lot, the system can push the latest list of available parking spaces to reduce blind detours.
[0010] Furthermore, the parking space information input module also includes a camera, which is placed in the target underground parking lot and is used to identify and obtain parking space status information.
[0011] When the camera based on the parking space information input module is used, the camera captures the parking space image and uses image processing technology to identify whether the parking space is occupied. When a vehicle parks in the parking space, the camera can capture the vehicle outline and thus determine that the parking space status is "occupied". Conversely, when the parking space is empty, it is judged to be "free", thereby reducing the frequency and cost of manual inspections and realizing the automation and intelligence of parking space management. At the same time, users can quickly query the location of free parking spaces through the user terminal, saving time in finding parking spaces.
[0012] Furthermore, the indoor map system is also used for path planning, which uses the shortest path algorithm to plan the navigation path based on the starting point location data and parking space information.
[0013] When using the above-mentioned path planning technology based on the indoor map system, it can dynamically receive the parking space status data provided by the parking space information input module, and integrate the user's starting position and target parking space position information in real time to improve parking efficiency. At the same time, the system calculates the shortest feasible path from the current vehicle position to the target parking space in real time, avoiding the lag of traditional fixed route navigation.
[0014] Furthermore, the indoor map system is also used to present navigation information, and presents the planned path and real-time location information to the user terminal through a display screen.
[0015] When the above-mentioned navigation information technology based on the indoor map system is used, it can dynamically receive the parking space status data provided by the parking space information input module, and integrate the user's starting position and target parking space position information in real time to improve parking efficiency. At the same time, the system calculates the shortest feasible path from the current vehicle position to the target parking space in real time, avoiding the lag of traditional fixed route navigation.
[0016] Furthermore, the user terminal includes a location sensing module, and the location sensing module adopts vehicle navigation, and the vehicle navigation obtains vehicle location data in real time.
[0017] When the above-mentioned location perception module based on the user terminal is used, it can provide high-precision positioning guarantee, improve the navigation experience, and shorten the positioning time.
[0018] Furthermore, the position sensing module is also used to perform correction processing on the acquired position data. The correction algorithm is implemented based on technologies such as map matching and historical trajectory analysis, and the corrected vehicle position information is presented to the user in real time, including displaying the vehicle's current position, distance to the target parking space, and other information on the navigation interface; When using the above-mentioned location data technology based on the location perception module, the correction processing effectively reduces the impact of GPS signal errors on navigation and improves the accuracy of vehicle position. It can assist users to understand the current position of the vehicle more accurately and avoid getting lost or taking the wrong route. At the same time, it can present the corrected vehicle position information in real time, including the current position, distance to the target parking space, etc., so that users can intuitively understand the navigation status and improve driving safety and convenience.
[0019] The present invention provides an underground parking lot navigation method, comprising the following steps: S1. After the user drives the vehicle into the target underground parking lot, he opens the mobile phone APP and connects to the indoor map system of the parking lot; S2. The indoor map system obtains the current status (free / occupied) of all parking spaces through the parking space information input module, and pushes a list of available parking spaces to the user terminal, including information such as the parking space number, location, and distance from the entrance. The user then views the available parking spaces recommended by the system or manually selects a specific parking space. S3. Based on the user's selected target parking space and the vehicle's current starting position, the system generates an optimal driving route using a shortest path algorithm, avoiding obstacles and congested areas. S4. The position sensing module continuously obtains the real-time position of the vehicle and corrects the positioning error through the correction algorithm. The navigation interface dynamically updates and displays the corrected current position of the vehicle, the remaining distance, and key path prompts such as turns and ramps. If the user deviates from the route, the system automatically replans the route; S5. Drive into the target parking space according to the navigation prompts. After successful parking, the system will automatically mark the parking space as "occupied".
[0020] Compared with the existing technology, the beneficial effect of the present invention is that the underground parking navigation system effectively solves the problems of difficulty in parking and finding parking spaces in underground parking lots. The underground parking navigation system of the present invention is mainly composed of two core parts: the user terminal and the indoor map system. The indoor map system is deployed in the target underground parking lot and is responsible for the collection, update and path planning of parking space information. The user terminal serves as the interactive interface between the user and the system to realize functions such as position perception and navigation information display. That is, through the above-mentioned docking with the indoor map system, real-time position perception and correction, intuitive navigation presentation and other functions, the indoor map system provides navigation path planning and navigation function implementation, and combines parking space input information to realize efficient and accurate parking navigation services, providing users with convenient and efficient parking navigation services, improving users' parking experience in underground parking lots, and reducing the time of finding parking spaces.
