Description

Technical Field

[0001] This application relates to the field of augmented reality technology, and more specifically, to a navigation display method, a navigation display device, a navigation system, and an electronic device. Background Technology

[0002] The targets of navigation covered in this application include people and vehicles. Traditional navigation display methods can be divided into two types: portable and fixed display devices. Portable devices include head-mounted, handheld, and vehicle-mounted devices. The advantage is that the device can move with the user or vehicle. The disadvantage is that a display device terminal needs to be equipped for each target, and it cannot provide navigation for users without a display device terminal. Fixed devices mainly include fixed screens and traffic light types. The advantage is that the user being navigated does not need to be equipped with a separate navigation display device. Fixed screen methods generally use large screens installed in fixed locations for multiple users to share navigation information. The disadvantage is that they cannot be moved. Traffic light navigation primarily uses the shape, color, flashing codes, or combinations of codes of traffic lights to transmit signals. Users being navigated need to identify or decode the specific navigation direction from the display or combined codes of one or more traffic lights (e.g., using two multi-color traffic lights, displaying red and green to represent left and green and red to represent right, or using left and right arrow-shaped traffic lights to indicate left and right). When approaching a fork in the road, users need to determine the direction before choosing a fork. If a direction (e.g., right) has multiple forks, even if the direction (e.g., right) is given, users are still prone to choosing the wrong fork. Moreover, in scenarios where multiple users are simultaneously navigating to different destinations, this can be confusing, lacking flexibility and intuitive usability. Summary of the Invention

[0003] This invention discloses a navigation display method and apparatus, eliminating reliance on a user's independent navigation display device terminal and proposing an augmented reality navigation display method. It displays navigation information in real-time in front of multiple users and can move synchronously with them, overcoming the main drawbacks of both fixed and mobile traditional navigation display devices. It can also simultaneously navigate multiple users to different destinations. During navigation, users do not need to determine direction based on the displayed information and then choose a branch road; they only need to follow the guidance of the displayed segments to reach their destination. Even if there are multiple branches in a certain direction (e.g., to the right), this application can still unambiguously indicate the target branch road and can simultaneously indicate the respective target branch roads to multiple users. The navigation path described in this invention refers to a directed curve connecting the starting point and the destination via a passable road, with the navigable target as the starting point and the destination as the ending point. Different navigable targets can have different navigation paths. Traditional methods display navigation routes on the user's navigation terminal display device or shared large screen. This invention can display the entire navigation route or segments on the road. This navigation display method is intuitive and easy to understand, and it is not easy to confuse multiple users navigating at the same time.

[0004] Firstly, this application provides a navigation display method: A navigation display device is pre-installed at the navigation location, the display device being arranged along the road alignment and branching into multiple alignments at road intersections; the display device is used to provide shared navigation for one or more navigable targets, allowing different navigable targets to have different navigation paths; by controlling the display device to display segments on the current road preceding the navigation path of the navigable target, the navigable target is guided to continue traveling along the current road; by controlling the display device to display segments on the target branch road where the navigation path of the navigable target is located, the navigable target is guided to select the target branch road. The segments displayed on the display device in this application can be a part or all of the navigation path of the navigable target.

[0005] According to the navigation display method provided in this application, the navigation of each navigable target includes the following steps:

[0006] Step S1: Obtain the current location and destination location of the target being navigated to;

[0007] Step S2: Based on the current location and destination location, plan the navigation route;

[0008] Step S3: Control the display device to display the segments of the navigation path ahead of the current position of the navigable target.

[0009] According to the navigation display method provided in this application, this method generates a visual effect of display segment movement by alternately displaying different segments on the display device to provide navigation for the user. The display segment is one or more display units that are displayed together on the display device, and different display segments may have zero or more overlapping display units.

[0010] Secondly, this technical solution provides a navigation display device, comprising at least a display device and a display control module. The display device is shared by one or more navigable targets, pre-installed at the navigation location, arranged along the road alignment, and branching into multiple alignments at road intersections, allowing different navigable targets to have different navigation paths. The display device on the current road ahead of the navigable target's current position displays segments to guide the navigable target to continue on the current road. The display device on the branch roads where the navigable target's navigation path is located displays segments to guide the navigable target to select the branch road. The display control module is used to control the segmented display on the display device to realize the display guidance function.

[0011] The navigation display device according to this application includes the display device, the display control module, and further includes an acquisition module and a planning module; the display device includes one or more display units, each of which can be independently addressed and controlled to display and stop display; the display control module has the function of controlling the display of segments composed of one or more display units on the display device to display and stop display through addressing; the acquisition module is used to acquire the current position and destination position of the navigable target; the planning module is used to plan a navigation path based on the current position and destination position of the navigable target.

[0012] Thirdly, based on the navigation display device provided in the second aspect, this technical solution provides a navigation system based on passive positioning. In addition to the navigation display device, it also includes a passive positioning module. The passive positioning module uses a positioning device pre-installed at the navigation location to locate one or more navigable targets. The navigable targets can complete passive positioning without receiving external beacon signals. The passive positioning module sends the calculated position of the navigable target to the acquisition module of the navigation display device, which then completes the navigation display task. The navigation system based on passive positioning can achieve positioning and navigation for navigable targets without terminal positioning devices or terminal display devices.

[0013] Fourthly, based on the navigation display device provided in the second aspect, this technical solution also provides a navigation system based on active positioning. In addition to the navigation display device, it also includes an active positioning module and a communication module. The active positioning module is located on the terminal device attached to the navigable target and positions the navigable target, for example, by using its own sensor devices to measure the angle or distance of the navigable target relative to a known beacon in the ambient space, and determining its position in the spatial coordinate system through the principle of triangulation. The communication module is used to communicate with the terminal device attached to the navigable target. Matching communication modules exist on both the terminal device of the navigable target and the navigation display device. Communication methods include Bluetooth, Wi-Fi, UWB, etc. The active positioning module calculates the current position of the navigable target and sends the current position to the acquisition module of the navigation display device through the communication module, so that the navigation display device completes the navigation display task.

[0014] Fifthly, according to the navigation display method described in the first aspect, this technical solution provides an electronic device, including the display device, and further including a memory and a processor; the memory stores a computer program; the processor may be one or more, and is configured to implement the acquisition, planning, and control functions described in the first aspect by executing the computer program.

[0015] Sixthly, according to the navigation display device described in the second aspect, this technical solution provides an electronic device, which, in addition to the aforementioned display device, also includes a memory, a processor, and a positioning device; the memory stores a computer program; the processor may be one or more, configured to execute the computer program to implement the functions of the functional modules described in the second aspect or any possible implementation of the second aspect; the positioning device is used to implement the functions of the passive positioning module described in the third aspect, and can use information acquired by a camera or radar device pre-installed at the navigation location and a computing processor to calculate the position of the navigable target.

[0016] In a seventh aspect, according to the navigation display device described in the second aspect, this technical solution provides an electronic device, which, in addition to the display device, also includes a memory, a processor, and a communication device; the memory stores a computer program; the processor may be one or more, and is configured to execute the computer program to implement the functions of the functional modules described in the second aspect or any possible implementation of the second aspect; the communication device is used to implement the functions of the communication module described in the fourth aspect.

[0017] Eighthly, this technical solution provides a computer-readable storage medium storing computer program instructions that implement the functions of the second aspect's functional modules. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this application, and do not constitute a limitation of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Figure 1 The schematic diagram of the linear arrangement of display units (e.g., 11, 12, 13, 14, 15) in the navigation display device 1 provided in this application embodiment shows that the display units branch into multiple linear configurations at intersections based on the forking road segments; although Figure 1 The illustration only shows a single-column arrangement of display units; however, multiple columns of display units can also be arranged side-by-side. The light-emitting components of the display units can be LED beads, light bars, screen panels, or optical projection devices, etc. This application does not limit the shape, color, light-emitting material, or manufacturing process of a single display unit. The segments displayed on the display device described in this application can be a portion or all of the navigation path of the navigating target. This application does not limit the length of the display segments guiding navigation on the navigation display device; the shortest display segment can use only one display unit, and the longest can use display units from all roads on the navigation path simultaneously. Furthermore, this application provides an embodiment of "alternating display of different segments on the display device to produce a visual effect of segment movement": For example... Figure 1 As shown, at time T1, the segment composed of display units 11, 12, and 13 is displayed; at time T2, the segment composed of display units 12, 13, and 14 is displayed; and at time T3, the segment composed of display units 13, 14, and 15 is displayed. Visually, this presents a display effect where the display segments, composed of three display units, move from left to right. This application also provides another embodiment of "alternating display of different segments on the display device to produce a visual effect of moving display segments": at time T1, the segment composed of display units 11, 12, and 13 is displayed; at time T2, the segment composed of display units 11, 12, 13, and 14 is displayed; and at time T3, the segment composed of display units 11, 12, 13, 14, and 15 is displayed. Visually, this presents a display effect where the display segments move from left to right and the length of the display segments gradually increases (from 3 display units to 5 display units). In other embodiments of this application, each display segment may also be presented with more complex display effects, such as cyclic flashing, marquee, multiple colors, etc., which are not limited by this invention.

[0030] This embodiment provides a preferred method: each navigable target has a corresponding display segment for navigation guidance; when navigating each navigable target, only a small segment of the road along its navigation path is displayed at any given time as the navigation guidance display segment; the display segment is preferably one meter in length, and under the control of the display control module described in this application, it is always located in front of the navigable target's navigation path and moves synchronously with the navigable target to provide visual navigation; when the navigable target stops, the corresponding display segment also stops moving; when the navigable target moves, the display segment corresponding to that navigable target also moves at the same speed. In the preferred method provided in this embodiment, the acquisition module, planning module, and display control module described in this application can use multi-process parallelism, multi-threaded concurrency, or time-sharing processing to simultaneously track the position status of multiple navigable targets and control the display segments of the corresponding nearby locations to display, thereby realizing the function of the navigation display device providing navigation for multiple navigable targets simultaneously. In another embodiment, all display units on all roads along the navigation path of the navigation target can be displayed simultaneously, with the display devices providing exclusive navigation for the navigation target; or multiple sets of linear display devices can be arranged in parallel along the road, with each set of display devices navigating only one navigable target at a time. The navigation paths of different navigable targets can be distinguished by the different colors or display methods displayed by the display units on each set of display devices (e.g., different frequencies of marquee display). This invention does not limit the number of display devices installed on each road.

[0031] Figure 2 Examples of navigation display devices provided in this application, which are deployed in a right-angle turn configuration on one-way streets and at intersections respectively; Figure 3 and Figure 4 This application illustrates two embodiments of the navigation display device deployed at one-way intersections and two-way intersections, respectively, using a right-angle turn configuration. Figure 2 , Figure 3 In the middle, display device 1 is arranged in a cross shape at the intersection. Figure 4 The central display device 1 is arranged in a grid pattern at the intersection.

[0032] Figure 5 and Figure 6 This application illustrates two embodiments of the navigation display device deployed at one-way intersections and two-way intersections using rounded corners, respectively. Figure 6 To facilitate understanding by implementers of this application and to avoid confusion caused by multiple lines, only one direction of travel and the corresponding three branch roads are shown at the intersection of two-way roads. The layout of other directions of travel is similar.

[0033] exist Figure 3 , Figure 4 , Figure 5 and Figure 6 The document also illustrates an example of navigation display segments on display device 1 guiding target 3. Display segment 23 guides target 3 to its left fork in the road, display segment 24 guides target 3 to continue straight along the current road, and display segment 25 guides target 3 to its right fork in the road. It is important to emphasize that although directional terms such as "left" and "right" are used in the description, this is merely for the convenience of the implementer. The target does not need to determine direction to choose a fork in the road. Even when there are multiple forks in a certain direction (e.g., the right), the method of this application can still unambiguously guide the target fork in the road. Furthermore, to save equipment, even on two-way roads, the display devices can be deployed in the same layout as on one-way roads, i.e., only one linear display device is deployed on each road segment for bidirectional navigation. The display devices described in this application can be installed close to the road surface or directly above the road surface; this application does not restrict the specific installation location of the display devices.

[0034] Figure 7 This is a flowchart illustrating the navigation display method provided in this application embodiment. The function of the method can be implemented by a separately configured hardware module or a software program running on a processor. Specifically, the function of obtaining the current position of the navigable target can be implemented by a positioning device pre-installed at the navigation location to locate the navigable target and then sending the location to the acquisition module of the navigation display device, or it can be calculated by the positioning device carried by the navigable target and then sent to the acquisition module of the navigation display device via a communication module. The function of planning and generating a navigation path can be completed on the processor of the navigation display device, or it can be completed on the processor of the navigable target's terminal and then sent to the navigation display device via a communication module.

[0035] Figure 8 This is a block diagram of a navigation system based on passive positioning used to implement the navigation display method of this embodiment. In a preferred embodiment, the passive positioning module can acquire environmental imaging information by using imaging devices such as cameras or imaging radars pre-installed at the navigation location, and then use a processor to identify the target being navigated from the environmental imaging information and calculate its current position. In another embodiment, the passive positioning module can also be implemented by using multiple ranging radars installed at known coordinate locations to measure the distance to the target being navigated, and then determining its position in the spatial coordinate system using the principle of triangulation.

[0036] Figure 9This is a block diagram of a navigation system based on active positioning used to implement the navigation display method of this disclosure. The positioning of the navigable target is completed by the positioning module on the terminal attached to the navigable target, and then sent to the acquisition module of the navigation display device via a communication module. The positioning module can be implemented as a GPS positioning device using GPS beacon signals, or as a positioning device using beacon signals based on technologies such as UWB (Ultra-wide band), Wi-Fi, Bluetooth, infrared, RFID, ultrasound, or laser for positioning.
