Description

Technical Field

[0001] The utility model belongs to the field of indoor navigation, and in particular relates to an indoor virtual guidance system based on a light tag guide belt and a light tag guide belt. Background Art

[0002] Nowadays, navigation technology has become an indispensable part of people's daily life. However, traditional digital maps have limitations in indoor navigation, especially in complex building environments. Buildings will block GPS signals, causing GPS signals to be unstable, resulting in low positioning accuracy and inability to achieve cross-floor navigation. Therefore, traditional GPS digital maps are not suitable for complex indoor navigation. In the current social context, people's demand for indoor positioning and navigation is growing, but traditional digital map technology often cannot meet the needs of indoor navigation in complex building environments.

[0003] At present, common indoor positioning and navigation technologies are divided into the following categories:

[0004] (1) Indoor positioning and navigation technology based on Bluetooth

[0005] Bluetooth-based indoor positioning technology is a technology that uses Bluetooth technology to achieve indoor positioning and navigation. This technology uses information such as the strength and arrival time of Bluetooth signals by arranging Bluetooth beacons or Bluetooth access points inside buildings to determine the location of mobile devices and provide corresponding navigation services. However, there are some problems with Bluetooth-based indoor positioning technology: First, its stability is poor and it is easily interfered by noise, especially in complex indoor environments, which seriously affects the accuracy of positioning. Second, the cost of Bluetooth devices and components is high, which increases the cost of deployment and maintenance, and limits its application in places with limited budgets. In addition, security issues cannot be ignored. The openness of Bluetooth signals may lead to data leakage or malicious tampering. Therefore, security measures need to be strengthened during deployment.

[0006] (2) Indoor positioning and navigation technology based on QR code

[0007] The core of this technology is to establish a location mapping relationship between the real world and a virtual scene that simulates the real world through a QR code. When a user scans a QR code with a terminal device, the terminal device reports the user's physical location information to the background based on the above mapping relationship. At the same time, the user selects his destination in the terminal device (such as a mobile phone), and the terminal device also reports the destination to the background. The background provides the user with a virtual guide service in the virtual scene based on the user's location and the destination he selected. However, the indoor positioning and navigation achieved by this technology is related to the location and number of QR codes posted, and the accuracy is difficult to guarantee.

[0008] In summary, there is an urgent need for a safe, stable, low-cost and highly accurate indoor positioning and navigation solution. Utility Model Content

[0009] In order to solve the above problems existing in the prior art, the utility model provides an indoor virtual guide system based on a light label guide belt and a light label guide belt.

[0010] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0011] An indoor virtual guide system based on a light tag guide belt, comprising: a light tag guide belt, a mobile terminal device and a background server;

[0012] The light tag guide belt is laid on an indoor road; the light tag guide belt is printed with guide arrows, and a light tag is arranged at a fixed interval; a two-dimensional code is printed on the light tag; the two-dimensional code is associated with the physical location of the light tag where it is located;

[0013] The mobile terminal device is communicatively connected to the backend server; wherein, the user uses the mobile terminal device to scan the QR code to report his current location together with his selected destination location to the backend server; the backend server provides the user with a virtual guide service through the mobile terminal device.

[0014] Optionally, a protective layer is provided on the surface of the light label guide belt.

[0015] Optionally, numbers are also printed on the light labels; the numbers printed on the light labels on different light label guide belts are different, and the numbers printed on the light labels on the same light label guide belt are the same.

[0016] Optionally, the system further includes: an environment perception sensor; the environment perception sensor is connected to the background server.

[0017] Optionally, the system further includes: an image acquisition device; the image acquisition device is connected to the background server.

[0018] Optionally, the mobile terminal device includes: a smart phone.

[0019] Optionally, the mobile terminal device includes: a tablet device.

[0020] The utility model also provides a light tag guide belt, which is laid on an indoor road; the light tag guide belt is printed with guide arrows, and a light tag is arranged at a fixed interval; a QR code is printed on the light tag; the pattern of the QR code is associated with the physical position of the light tag where it is located, so that the user can obtain his current position by scanning the QR code.

[0021] Optionally, a protective layer is provided on the surface of the light label guide belt.

[0022] Optionally, numbers are printed on the light labels; the numbers printed on the light labels on different light label guide belts are different, and the numbers printed on the light labels on the same light label guide belt are the same.

[0023] The utility model provides an indoor virtual guide system based on a light tag guide belt, including a light tag guide belt, a mobile terminal device and a background server; wherein the light tag guide belt is laid on an indoor road; a guide arrow is printed on the light tag guide belt, and a light tag is provided at a fixed interval; a QR code is printed on the light tag; the QR code is associated with the physical location of the light tag where it is located. In this way, when a user scans the QR code using a mobile terminal device, his current location can be reported to the background server together with the destination location selected in the mobile terminal device, and the corresponding background server provides the user with a guide service between the two locations. Therefore, the use of light tags for positioning gets rid of the problem of limited use of traditional GPS signals indoors, and realizes accurate indoor positioning and navigation.

[0024] Among them, since the light tags on the light tag guide belt are set at fixed intervals, when establishing the association relationship between the QR code and the physical position of the light tag where it is located in the early stage, as long as the association relationship between a QR code on the light tag guide belt and the physical position is established, the association relationship between other QR codes on the light tag guide belt and the physical position of the light tags where they are located can be determined accordingly without the need to associate them one by one. Therefore, the implementation method of the embodiment of the utility model to map the indoor environment of the real world into the virtual world is relatively simple, and there is no need to consider the posting position and number of QR codes. In addition, since the light tags on the light tag guide belt are set at fixed intervals, it is equivalent to dividing the indoor roads according to the fixed path length granularity. Therefore, the positioning and navigation accuracy of this system is actually determined by the size of the path length granularity, so it can achieve indoor positioning and navigation with high accuracy. When the path length granularity is set to less than one meter, the positioning accuracy is even not inferior to the indoor positioning and navigation technology based on Bluetooth. Furthermore, the cost of the system is much lower than that of the indoor positioning and navigation technology based on Bluetooth, and the stability and security of the system provided by the utility model are also better than those of the indoor positioning and navigation technology based on Bluetooth.

[0025] In summary, the indoor virtual guide system based on the optical tag guide belt provided by the utility model realizes safe, stable, low-cost and highly accurate indoor positioning and navigation.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention is further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0034] In the field of navigation, outdoor navigation has been applied on a large scale, with outstanding performance in product maturity and scientific design, covering multiple scenarios in people's daily life. However, their limitations are mainly reflected in the fact that they are mainly for outdoor navigation and cannot achieve indoor-level precise navigation. In terms of indoor navigation, indoor positioning and navigation technology based on Bluetooth and indoor positioning and navigation technology based on QR codes have their own defects, making it difficult to meet the requirements of security, stability, accuracy and low cost at the same time.

[0035] In order to solve the above problems, the present invention provides an indoor virtual guide system based on light label guide belts. Figure 1 The system includes: an optical tag guide belt, a mobile terminal device and a background server.

[0036] The light label guide belt is laid on the indoor road; the light label guide belt is printed with guide arrows, and a light label is set at a fixed interval, and the light label is a laser-printed label. A QR code is printed on the light label; the QR code is associated with the physical location of the light label where it is located.

[0037] The mobile terminal device is connected to the backend server in communication, and the mobile terminal device includes: a smart phone or a tablet device. The user uses the mobile terminal device to scan the QR code and report his current location and the selected destination location to the backend server; the backend server provides the user with a virtual guide service through the mobile terminal device.

[0038] In actual applications, users can easily enter the 3D guidance interface provided by mobile terminal devices by scanning the QR code on the light tag guide strip. In this interface, users can independently select indoor destinations. The backend server provides users with virtual guidance services through mobile terminal devices based on the destination location selected by the user and the physical location of the QR code scanned by the user, thereby providing users with an efficient, intuitive and convenient indoor navigation experience. Users can obtain accurate road guidance in real time and easily find their destinations.

[0039] Among them, the mobile terminal device is mainly used to provide a user interface, receive user operation instructions, and send the user's selection and operation instructions to the background server.

[0040] The backend server is used to provide the construction and rendering of the virtual environment, and display it on the user interface through the mobile terminal device, thus forming a three-dimensional guide interface.

[0041] It is understandable that based on virtual guide technology, users can view the virtual guide map inside the building in real time on mobile terminal devices, including real-time location identification, path planning, building layout and other information, thereby achieving efficient and convenient indoor navigation experience. In addition, virtual guide technology can also provide personalized navigation services in combination with the special layout and functional requirements of the building. For example, in a shopping mall, users can not only get accurate store navigation, but also realize intelligent shopping route planning based on personal preferences and shopping lists.

[0042] Regarding navigation, the specific implementation method of the background server navigating according to the destination location and the location where the user is when scanning the QR code has been implemented in the relevant prior art, and there are many implementation methods. A simple implementation method is to pre-set the navigation path between the physical locations associated with each two QR codes, so that when the background server obtains the user's destination location and the location where the user is when scanning the QR code, the navigation path between the two locations can be directly pushed to the mobile terminal device, and the mobile terminal device provides navigation services according to the navigation path in its three-dimensional guide interface. The principle of this implementation method is simple, but for indoor environments such as relatively fixed (no traffic factors) and scenarios where the route does not change much, it can efficiently and accurately meet the user's navigation needs. The complex implementation method is similar to Amap and Baidu Maps, which perform intelligent navigation path planning between the destination location and the location where the user is when scanning the QR code, thereby pushing the optimal navigation path to the mobile terminal device, and the corresponding mobile terminal device provides navigation services according to the optimal navigation path in its three-dimensional guide interface. It is understandable that, unlike outdoor navigation scenarios, map data for indoor navigation scenarios is relatively simple, and does not require identification of actual roads, nor does it require matching information such as road features and indoor landmarks with map data. The present utility model embodiment does not limit the navigation method.

[0043] When mobile terminal devices provide navigation services in their three-dimensional guidance interface, the augmented reality (AR) technology used can combine virtual navigation instructions with actual road scenes, so that the navigation route presents a three-dimensional spatial layout, achieves accurate navigation, and can display the remaining distance in real time, fully displaying the surrounding environment. Users can see the real-time road scene on the mobile phone screen, intuitively understand the layout of the entire building, obtain the route to the destination from the first-person perspective, obtain a three-dimensional spatial navigation experience, and obtain arrow instructions, remaining distance and other related navigation information when needed, thereby providing users with a more intuitive and easier-to-understand navigation experience.

[0044] When actually building the system, you can use the MAYA modeling software teaching building model, and use PR (Adobe PremierePro) and AE and other software tools to render the scene demonstration video. The effect is as follows Figure 3 , Figure 4 In addition, you can also use MAYA, 3DSMAX, AE and other software tools to import real-life materials and render augmented reality demonstration videos of virtual guides. The effect is as follows Figure 5 , Figure 6As shown. The implementation method of virtual environment construction and rendering is already a mature prior art, and the embodiments of the utility model will not be repeated. After completing the construction and rendering of the virtual environment, a light label guide belt is laid on the indoor road of the teaching building, and then the QR code on the light label guide belt is associated with its physical location, so that virtual guidance can be performed based on the teaching building model.

[0045] When laying light label guide strips on the indoor roads of the teaching building, one light label guide strip can be laid on one road. When laying, it is preferred to use a light label guide strip with a light label spacing of 1 meter (m) to accurately distinguish the classroom doorways that are closer, but of course it is not limited to this.

[0046] In addition, when associating the QR code on the light tag guide belt with its physical location, for areas without landmarks (such as classroom doors), batch operations can be performed during association. For example, for a corridor without key points (doors, fire hydrants, etc. are usually key points), after laying the light tag guide belt in the corridor, it is only necessary to manually associate the physical location of one of the QR codes, and the physical locations of the remaining QR codes can be obtained based on their relative distances from the QR code, thereby achieving batch association. For example, assuming that the QR code associated position at the entrance of a corridor is the entrance to the west corridor on the second floor of Building C, the physical locations of other QR codes on the same light tag guide belt can be associated with the entrance to the west corridor on the second floor of Building C + 1m, the entrance to the west corridor on the second floor of Building C + 2m, the entrance to the west corridor on the second floor of Building C + 3m, etc., and so on. After the QR code association is completed, multiple locations can be selected in the teaching building for testing to ensure the accuracy of the association.

[0047] The utility model provides an indoor virtual guide system based on a light tag guide belt, including a light tag guide belt, a mobile terminal device and a background server; wherein the light tag guide belt is laid on an indoor road; a guide arrow is printed on the light tag guide belt, and a light tag is provided at a fixed interval; a QR code is printed on the light tag; the QR code is associated with the physical location of the light tag where it is located. In this way, when a user scans the QR code using a mobile terminal device, his current location can be reported to the background server together with the destination location selected in the mobile terminal device, and the corresponding background server provides the user with a guide service between the two locations. Therefore, the use of light tags for positioning gets rid of the problem of limited use of traditional GPS signals indoors, and realizes accurate indoor positioning and navigation.

[0048] Among them, since the light tags on the light tag guide belt are set at fixed intervals, when establishing the association relationship between the QR code and the physical position of the light tag where it is located in the early stage, as long as the association relationship between a QR code on the light tag guide belt and the physical position is established, the association relationship between other QR codes on the light tag guide belt and the physical position of the light tags where they are located can be determined accordingly without the need to associate them one by one. Therefore, the implementation method of the embodiment of the utility model to map the indoor environment of the real world into the virtual world is relatively simple, and there is no need to consider the posting position and number of QR codes. In addition, since the light tags on the light tag guide belt are set at fixed intervals, it is equivalent to dividing the indoor roads according to the fixed path length granularity. Therefore, the positioning and navigation accuracy of this system is actually determined by the size of the path length granularity, so it can achieve indoor positioning and navigation with high accuracy, and when the path length granularity is set to less than one meter, the positioning accuracy is even not inferior to the indoor positioning and navigation technology based on Bluetooth. Moreover, the cost of the system is much lower than that of the indoor positioning and navigation technology based on Bluetooth, and the stability and security of the system are also better than those of the indoor positioning and navigation technology based on Bluetooth.

[0049] In one embodiment, the surface of the light label guide belt is provided with a protective layer, so that the two-dimensional code on the light label guide belt can be prevented from being damaged or contaminated. The protective layer can be a layer of waterproof and anti-fouling tape, but is not limited thereto.

[0050] In one embodiment, numbers are also printed on the light labels; the numbers printed on the light labels on different light label guide belts are different, and the numbers printed on the light labels on the same light label guide belt are the same.

[0051] It is understandable that when there are many indoor roads, if a different QR code is printed for each light tag, the number of QR codes will be large, which is not conducive to the mass production of light tag guide belts. Therefore, in order to reduce the number of QR codes, by printing different numbers on the light tags on different light tag guide belts, the reuse of QR codes on different light tag guide belts can be achieved. Since in practice, mobile terminal devices will take images when scanning QR codes. Therefore, when the user uses a mobile terminal device to scan the QR code, the mobile terminal device can also obtain the number printed on the light tag at the same time. Based on simple image recognition technology, the number printed on the light tag can be identified. Therefore, when the QR code is associated and the QR code is scanned in actual navigation, the light tags with the same QR code and different numbers can be distinguished, so that the light tags are actually one-to-one corresponding to the physical location.

[0052] In one embodiment, the system further includes: an environment perception sensor; the environment perception sensor is connected to a background server.

[0053] Here, the environment perception sensor may include: a temperature sensor, a humidity sensor and / or a sensor for sensing light intensity, etc. The environment perception sensor is used to sense indoor environment information, so that the background server can refer to the environment information when constructing and rendering the virtual environment, so that the video presented during the virtual guide is more in line with the real-time environment.

[0054] In one embodiment, the system further comprises: an image acquisition device; the image acquisition device is connected to a background server, so that the background server can introduce real-time real scene information when constructing and rendering a virtual environment.

[0055] In summary, the indoor virtual guide system based on the optical tag guide belt provided by the utility model realizes safe, stable, low-cost and highly accurate indoor positioning and navigation.

[0056] The indoor virtual guide system based on the light tag guide belt provided by the utility model can be applied to places such as shopping malls, airports, hospitals, etc., providing a more intelligent and efficient indoor navigation solution for people's life and work.

[0059] In one embodiment, numbers are also printed on the light labels; the numbers printed on the light labels on different light label guide belts are different, and the numbers printed on the light labels on the same light label guide belt are the same.
