Description

Technical Field

[0001] The present invention relates to the space guidance industry, and in particular to an underground space path-finding assistance system based on three-dimensional display of ground markers. Background Art

[0002] With the continuous acceleration of urbanization, urban populations are becoming increasingly dense, and land resources are becoming increasingly scarce. In order to meet the needs of urban development, the development and utilization of underground space has continued to expand, including underground parking lots, underground shopping malls, subway networks, underground integrated pipe galleries and other underground facilities. However, while these complex underground spaces bring convenience to people's lives, they also bring a series of difficult path-finding problems.

[0003] In the past, wayfinding in underground spaces mainly relied on traditional maps and simple signage. These maps are often not intuitive enough, and it is difficult for pedestrians to accurately grasp the complex three-dimensional structure and channel layout of underground spaces through maps. Markers play an important reference role in the wayfinding process, but the existing wayfinding assistance system is difficult to intuitively display the direction and distance of markers in terms of visual perception. The lack of significant reference objects can easily cause pedestrians to get lost. In view of the above technical problems, it is urgent to develop an underground space wayfinding assistance system based on the three-dimensional display of ground markers. Summary of the invention

[0004] The purpose of the present invention is to provide an underground space path-finding assistance system based on three-dimensional display of ground markers to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An underground space pathfinding assistance system based on three-dimensional display of ground markers, comprising:

[0007] Structural fixed frame;

[0008] A camera module, wherein the camera module is connected to the structural fixing frame;

[0009] An image transmitter, which is connected to the camera module and is used to transmit the image captured by the camera module to the central processing unit;

[0010] A display screen fixing frame, wherein the display screen fixing frame is connected to the structure fixing frame;

[0011] A high-definition display screen is embedded and fixedly connected to a display screen fixing frame, and is used to provide a three-dimensional ground marker display to help users identify directions.

[0012] Compared with the prior art, the beneficial effects of the present invention are: by displaying real-life images viewed from underground space installation nodes toward ground markers, an intuitive three-dimensional spatial reference is provided for users, enabling them to determine their position and direction of travel more quickly and accurately, effectively reducing the chances of getting lost in underground space, and improving path-finding efficiency. The present invention solves the problems of small visible range and limited information of traditional signboards, and poor signal and non-intuitive two-dimensional display of electronic maps in underground space, thereby providing an innovative and effective solution for path-finding in underground space.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] An underground space path-finding assistance system based on three-dimensional display of ground markers, in one embodiment of the present invention, includes: a structural fixed frame 1; a camera module 2, the camera module 2 is connected to the structural fixed frame 1; an image transmitter 3, the image transmitter 3 is connected to the camera module 2, and is used to transmit the image collected by the camera module 2 to a central processing unit; a display screen fixed frame 4, the display screen fixed frame 4 is connected to the structural fixed frame 1; a high-definition display screen 5, the high-definition display screen 5 is embedded and fixedly connected to the display screen fixed frame 4, and is used to provide a three-dimensional display of ground markers to help users identify directions.

[0018] In one embodiment of the present invention:

[0019] The setting of the pathfinding assistance system also follows the following principles: in underground parking lots, for multi-story parking lots, the entrances and exits of each floor, the intersections of passages in parking-dense areas, the forks leading to different parking areas, and the entrances and exits of the ramps connecting the upper and lower floors are all set as installation nodes; for the subway network, the forks of transfer passages of different lines in each transfer station, the entrances and exits from the platform to the station hall, and the forks in the station hall leading to different exit directions are set as installation nodes.

[0020] Underground parking lot: In a multi-storey parking lot, the entrance and exit of each floor are key locations for users to enter and exit the parking lot. Setting them as installation nodes can help users determine the starting and ending locations. The intersections of passages in areas with dense parking spaces and the forks leading to different parking areas can guide users to find the target parking space or the path to leave the parking lot during the parking process.

[0021] Underground shopping malls: The intersections of the passages in the concentrated store areas are the places where customers frequently pass by during the shopping process. Setting up installation nodes can facilitate them to shuttle between different stores. The stairs and elevator entrances and exits between different floors are the key to vertical transportation. The intersections leading to different functional areas of the mall (such as dining areas, entertainment areas, and shopping areas) can help customers quickly find the areas they want to go.

[0022] Subway network: The intersections of transfer passages for different lines in each transfer station, the entrances and exits from the platform to the station hall, and the intersections leading to different exit directions in the station hall are all places where passengers can easily get lost. Setting them as installation nodes can effectively assist them in transferring and exiting the station.

[0023] In one embodiment of the present invention:

[0024] The camera module is a high-resolution, wide-angle camera installed at each device installation node. Its shooting direction is toward the ground markers, and the acquisition viewing angle range covers the entire picture of the ground markers that can be seen from this node; the resolution of the high-definition display screen is not less than 1080P, with high contrast and wide viewing angle, ensuring that the displayed image can be clearly seen from all directions under different lighting conditions; the high-definition display screen also includes a brightness adjustment sensor, which automatically adjusts the brightness of the display screen according to the ambient light intensity of the underground space.

[0025] The camera module's shooting direction is toward the ground markers, and its acquisition viewing angle range should cover the entire ground marker that can be seen from this node, ensuring that users can see complete and accurate ground marker information, thereby determining their relative position in the underground space. In order to ensure the clarity of image acquisition, the acquisition equipment has an automatic cleaning function, including a timed automatic water spray to clean the lens and an automatic air drying system. Even in harsh environments such as underground dust, clear images can be continuously obtained.

[0026] In one embodiment of the present invention: the path-finding assistance system further comprises an image updating module, which regularly updates the display image, and the updating period is set according to the change of the ground markers and the use frequency of the underground space; the path-finding assistance system comprises a remote monitoring center, which is connected to the high-definition display screen 5 of each installation node through a communication network, and can remotely view the display status and equipment operation status of each node, and can remotely adjust the display content;

[0027] The system is equipped with an image update module, which can regularly update the display image. The update cycle can be set according to the changes in the ground markers (such as new buildings, marker removal, etc.) and the frequency of use of the underground space. It can ensure that the displayed image is always consistent with the actual ground marker situation, providing users with accurate path finding references. The system includes a remote monitoring center, which is connected to the display device of each device installation node through the network. In the remote monitoring center, the display status and equipment operation of each node can be remotely viewed, such as whether the display screen is working properly, whether the brightness is appropriate, and whether the camera collecting images is collecting normally. And the display content can be adjusted remotely. If a display image is found to be abnormal or needs to be adjusted according to the actual situation (such as temporary traffic control causing changes in the situation around the ground marker), it can be handled in time. When a display device failure is detected, the remote monitoring center can automatically issue an alarm and send the fault location and fault type information to the maintenance personnel for rapid maintenance to reduce the impact on the path finding assistance system.

[0028] In one embodiment of the present invention:

[0029] When the remote monitoring center detects a failure in a display device, it can automatically issue an alarm and send the fault location and fault type information to the maintenance personnel;

[0030] A user feedback device is set up in a conspicuous position in the underground space, and users can provide feedback on the use of the path-finding assistance system through voice, touch or keystroke. When users report problems such as unclear display images, inappropriate display brightness, or difficulty in path-finding, these feedback information will be transmitted to the remote monitoring center, which will optimize and adjust the system based on the feedback information, including adjusting the content of the displayed image (such as adjusting the image angle, zoom ratio, etc.), the brightness and angle of the display device, etc., to improve the system's path-finding assistance effect and user experience.

[0031] In summary, by displaying real-life images of ground markers viewed from underground installation nodes, users are provided with an intuitive three-dimensional spatial reference, allowing them to determine their position and direction of travel more quickly and accurately, effectively reducing the chances of getting lost in underground spaces and improving path-finding efficiency. This solves the problems of small visible range and limited information of traditional signboards, and poor signal and non-intuitive two-dimensional display of electronic maps in underground spaces, providing an innovative and effective solution for path-finding in underground spaces.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
