[0017] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0018] In driving scenarios, a driver's attention needs to be divided among different actions. The external driving environment requires focused attention, while the content on the navigation map also requires some attention. However, every time a driver looks down at the map while driving, it consumes a certain amount of their attention. When the driver shifts their gaze from the driving environment to the map, there is a significant safety risk.
[0019] The above scenario presents a contradiction: the higher the vehicle speed, the longer the driver needs to focus on the driving environment, but the navigation map will still provide the driver with as much information as possible. Therefore, when the vehicle is traveling at high speed, the driver needs to pay more attention and shift their gaze for longer when looking at the map, resulting in obvious safety risks.
[0020] This disclosure proposes a method for processing map information, which can dynamically adjust the display density of map information in a navigation map based on vehicle driving information. For example, when the vehicle is traveling at low speed or on a low-speed road, high-rich information is provided in the map; when the vehicle is traveling at high speed or on a highway, low-rich information is provided, thus providing useful information to the driver while ensuring the driver's safety as much as possible.
[0021] Figure 1 This is a flowchart illustrating a map information processing method provided according to an embodiment of this disclosure, such as... Figure 1 As shown, the method includes the following steps:
[0022] Step S102: Display the original map on the vehicle's display interface, wherein the original map includes the initial marked objects.
[0023] The display interface can be any screen on an in-vehicle system located within the vehicle. This interface can be used to display the original map or the target map to users in the vehicle, such as the driver, allowing the driver to obtain map information by viewing the map on the interface. Optionally, the vehicle can include various in-vehicle systems that provide screen display functionality, such as an instrument panel display system, a head-up display (HUD) system, a reversing assistance system, a multimedia control system, or a main control system for human-machine interaction control of various systems within the vehicle. The display screens of these various in-vehicle systems can be located directly in front of the driver's seat, at the bottom of the windshield, or on the side of the vehicle interior for the driver to view. Furthermore, the display screen can even be located on the back of the front seats, or on the ceiling or side of the rear passenger area for rear passengers to view. The vehicle's display interface in this application can be any screen from the various types of system screens mentioned above, and all of these display screens can present the original map and the target map described in this application. Optionally, the original map in this step and the target map in subsequent steps can be navigation maps used to provide navigation information to the driver.
[0024] It should be noted that the original map may be a map generated in the previous moment according to the map information processing method of the present disclosure embodiment. Since the driving state of the vehicle has changed at the current moment, the original map generated in the previous moment can be adjusted into a target map and displayed on the display interface using the map information processing method provided in the present disclosure embodiment, thereby realizing the dynamic updating of the map in the display interface.
[0025] Optionally, the initial labeled objects included in the original map and the target labeled objects included in the target map can be elements within the geographical scope of their respective maps, such as points of interest (POIs). Those skilled in the art will understand that a point of interest on a map is an information point in a navigation map; in a geographic information system, a point of interest can refer to a house, a mailbox, a shop, a school, etc. Optionally, each point of interest can include four aspects of information: name, category, coordinates, and classification. This allows the name of the point of interest to be displayed at the location corresponding to its coordinates on the digital map, thus marking the point of interest on the digital map.
[0026] Step S104: During the vehicle's operation, acquire driving information that characterizes the vehicle's driving status.
[0027] It should be noted that the aforementioned driving information can be used to describe the vehicle's driving status during operation, such as the vehicle's speed, whether the driving status is safe, and whether the vehicle is traveling on rural roads or highways. Those skilled in the art will understand that the type and amount of information a driver needs to focus on on the map differs depending on the vehicle's driving status. Therefore, adjusting the status of the marked objects on the map displayed on the vehicle's interface according to the vehicle's driving status can provide the driver with a more tailored visual map. As an optional embodiment, the driving information may include at least one of speed information and road information, where speed information represents the vehicle's speed and road information represents the type of road the vehicle is traveling on.
[0028] Step S106: Determine the target display density corresponding to the vehicle's driving information.
[0029] The solution provided in this disclosure can dynamically adjust the target display density of marker objects in the navigation map displayed on the interface based on different driving states of the vehicle. It should be noted that the target display density and standard display density in this application can be parameter values characterizing the density of marker objects distributed on the map, used to describe the proportional relationship between the number of marker objects in the map displayed on the interface and the area of the map displayed on the interface. The area of the map can be represented by the area of the actual geographical region represented by the map, or by the screen area used to display the map on the display interface. For example, if the size of the display interface on the screen is 50cm × 30cm, and 40% of the area of the display interface is used to present the map, then the areas of the original map and the target map can be determined to be 600cm². 2 (50cm×30cm×40%), if the target density is 0.05 particles / cm². 2 The target display density indicates that it is desired to present about 30 target objects in the target map, so as to achieve the requirement that the distribution density of target objects in the area of the original map matches the target display density.
[0030] For example, in driving scenarios where drivers need to focus a lot of attention on the environment, the display interface can provide drivers with navigation maps with a lower target display density. In driving scenarios where the vehicle is in a safer state, drivers can focus more on the navigation map, so the display interface can provide drivers with navigation maps with a higher target display density and richer details. This function can be achieved by adjusting the target display density of the map.
[0031] Step S108: Determine the target identification objects located within the area of the original map based on the target display density, wherein the distribution density of the target identification objects within the area of the original map matches the target display density.
[0032] Step S110: Display a target map including target identifiers in the display interface, wherein the target map is obtained by replacing the initial identifiers in the original map with the target identifiers.
[0033] Optionally, both the original map and the target map can be navigation maps displayed to the driver. It should be noted that there are multiple adjustment methods available for the markers in the original map, depending on the specific circumstances. For example, if the initial number of markers in the original map exceeds the required display density, new markers can be added to obtain the target markers. Conversely, if the initial number of markers in the original map is less than the required display density, some markers can be removed from the initial number to obtain the target markers. Both methods involve adjusting the original map based on the initial markers.
[0034] As an optional embodiment, when adjusting the marker objects in the original map based on the display density, the target marker objects located within the area of the original map can be determined in the following way: obtain the marker object set corresponding to the original map, wherein the marker object set includes marker objects located within the geographical area corresponding to the original map; determine the target marker objects from the marker object set according to the target display density, so that the distribution density of the target marker objects within the area of the original map matches the target display density.
[0035] Optionally, the set of identified objects can consist of all identified objects within the geographical area corresponding to the original map. In this optional embodiment, all identified objects within the area of the original map can be placed into a set of identified objects. The number of target identified objects can be obtained by multiplying the area of the original map by the target display density. Then, identified objects that meet the required number can be selected from the set of identified objects, and the selected objects can be used as target identified objects.
[0036] As an optional embodiment, when adjusting the original map displayed in the display interface, the following method can be used: clear the initial marker objects in the original map to obtain a blank map; add the target marker objects to the blank map to obtain the target map; and display the target map in the display interface.
[0037] In this optional embodiment, in order to adjust the initial marker objects in the original map, the initial marker objects used as a reference can be discarded, and the number of target marker objects that meet the target display density can be directly determined from the geographical area corresponding to the original map. In this optional solution, the initial marker objects in the original map can be cleared first, and then the target marker objects selected from the marker object set can be directly marked on the original map to obtain a target map in which the number of target marker objects matches the target display density.
[0038] As another optional embodiment, when adjusting the original map displayed in the display interface, the following method can also be adopted: compare whether each object in the initial identifier object is repeated with each object in the target identifier object, keep the repeated objects in the initial identifier object and the target identifier object in the original map, delete the objects included in the initial identifier object but not included in the target identifier object from the original map, add the objects not included in the initial identifier object but included in the target identifier object to the original map, and thus obtain the target map. At this time, each object included in the target map is the target identifier object, thus achieving the purpose of updating the original map to the target map.
[0039] It should be noted that the set of labeled objects can be a collection of all labeled objects within the geographic area corresponding to the original map. For example, there may be several different types of points of interest within the geographic area corresponding to the original map, and all of these points of interest constitute the set of labeled objects.
[0040] In addition, controlling the number of target identification objects to match the target display density can include a variety of schemes. For example, the difference between the density of target identification objects in the target map and the display density can be no greater than a preset threshold, or the number of target identification objects can be determined to be less than the number required by the display density as a match.
[0041] Since the target display density is determined based on driving information used to describe the vehicle's driving status, steps S106 to S110 dynamically adjust the density of marker objects in the navigation map on the display interface according to the vehicle's driving status. By adding or removing marker objects in the original map, target marker objects that meet the target display density are marked on the target map and presented to the driver, allowing the driver to view a map that meets their information density requirements under different driving conditions.
[0042] Through the above steps, the technical objective of providing drivers with navigation maps that match the vehicle's driving status can be achieved. This solves the technical problem that drivers cannot quickly retrieve effective information from navigation maps while the vehicle is traveling at high speed, thus improving the efficiency of drivers retrieving information from navigation maps.
[0043] As an optional embodiment, in order to determine the target display density corresponding to the vehicle's driving information, the following steps can be taken: obtain the standard display density corresponding to the display interface; determine the display density coefficient based on the driving information; and determine the target display density based on the standard display density and the display density coefficient.
[0044] Optionally, the standard display density can correspond to the display density of marked objects on the map when the vehicle is stationary, or it can correspond to the display density of marked objects on the map displayed when the vehicle is in a specific driving state. By selecting a standard display density, target display densities can be defined based on this standard density for different driving states of the vehicle. For example, if the current driving state of the vehicle is safer than the driving state corresponding to the standard display density, the standard display density can be appropriately increased to obtain the target display density. In this case, more marked objects can be displayed on the target map for the user to read. If the current driving state of the vehicle is more dangerous than the driving state corresponding to the standard display density, such as a higher speed or a more unsafe road, the standard display density can be appropriately reduced to obtain a smaller target display density. This guides the display of fewer marked objects on the target map, preventing the map from becoming too cluttered and requiring more effort from the user. It should be noted that the value of the standard display density can be set by the navigation map developer or by the navigation map user. Generally, the user of the navigation map is the driver of the vehicle.
[0045] Furthermore, the range of values for the display density coefficient can vary depending on the definition of standard display density. For example, if standard display density is defined as the display density of objects marked on the map under the safest driving conditions, then the range of values for the display density coefficient can be determined as [0,1], with the specific value determined based on driving information. The safest driving conditions refer to the driving state when the vehicle is parked and stationary. Alternatively, if the display density of objects marked on the map corresponding to other standard driving conditions is defined as standard display density, then the range of values for the display density coefficient can be greater than 1. When the current driving state is determined to be safer than the standard driving state based on driving information, the specific value of the display density coefficient can be greater than 1. When the current driving state is more dangerous than the standard driving state, the specific value of the display density coefficient is between 0 and 1. It should be noted that when the vehicle's speed is higher, the driving state is generally considered more dangerous; or when the speed limit of the road the vehicle is traveling on is higher, the driving state is generally considered more dangerous. At this point, the driver needs to focus more on observing the external environment. Therefore, reducing the display density of markers on the target map can reduce the driver's attention expenditure on the navigation map, thereby reducing the driving risks caused by the driver looking down at the map.
[0046] Selecting a reasonable target display density for the target map can be achieved by determining a reasonable display density coefficient. As an optional embodiment, a vehicle speed coefficient can be determined first based on the speed information included in the driving information, wherein the vehicle speed coefficient is negatively correlated with the vehicle's driving speed; then, a road coefficient can be determined based on the road information included in the driving information, wherein the road coefficient is negatively correlated with the average driving speed of vehicles corresponding to the road type; finally, a display density coefficient can be determined based on the vehicle speed coefficient and / or the road coefficient.
[0047] In this optional embodiment, the display density coefficient can be determined solely based on the vehicle speed coefficient, solely based on the road coefficient, or jointly based on both the vehicle speed coefficient and the road coefficient. By setting the vehicle speed coefficient to be negatively correlated with the vehicle's speed, the vehicle speed coefficient can be reduced as the vehicle's speed increases, thereby reducing the display density coefficient. The physical meaning of this scheme is that when the vehicle's speed increases, the driver is expected to pay more attention to the external driving environment. By reducing the display density of markers on the navigation map, the driver can easily see the information on the map, quickly browse the map and obtain the information they need, and then look back to continue paying attention to the external driving environment, greatly improving safety. Similarly, the physical meaning of setting the road coefficient to be negatively correlated with the average vehicle speed corresponding to the road type is that when the average vehicle speed of the road the vehicle is traveling on increases, the driving environment is considered more dangerous. Therefore, by reducing the information density in the navigation map, the driver can reduce the time and effort spent looking at the navigation map. The road type can include highways, expressways, ordinary roads, internal roads, etc., with the average vehicle speed corresponding to each of these road types decreasing sequentially.
[0048] It should be noted that the negative correlation between the speed coefficient and vehicle speed can be linear. For example, a function can be constructed based on the speed coefficient and vehicle speed, where the speed coefficient is the function value and the vehicle speed is the independent variable, and the speed coefficient decreases as the vehicle speed increases. Alternatively, the negative correlation can be represented by dividing the speed into different intervals, with each speed interval corresponding to a speed coefficient, and the speed coefficient corresponding to the interval with the higher the average speed being smaller.
[0049] Figure 2 This is a schematic diagram of the vehicle speed coefficient value table provided according to the optional embodiments of this disclosure, such as... Figure 2 As shown, the vehicle speed coefficient is generally negatively correlated with the vehicle's speed. The vehicle's speed can be divided into four ranges: 0-30km / h, 30-60km / h, 60-120km / h, and above 120km / h. By collecting the vehicle's speed information, the vehicle's speed can be determined, and the vehicle speed coefficient corresponding to the current speed range can be used to determine the display density of the marked objects on the map.
[0050] Optionally, when determining the display density coefficient based on the vehicle speed coefficient and the road coefficient, it can be based on the following formula:
[0051] Display density coefficient = vehicle speed coefficient * vehicle speed weight + road coefficient * road weight
[0052] The above formula balances the impact of vehicle speed and road type on display density, thus providing a display density coefficient that reflects the vehicle's current driving state. It should be noted that the speed and road weights can be set according to the driver's personal preferences, and an optimal weighting that aligns with the driver's habits can be obtained through driver testing.
[0053] As an optional embodiment, the target identifier object can be determined from the identifier object set by the following steps: obtaining the identifier object priority corresponding to the vehicle; determining the target identifier object from the identifier object set based on the target display density and the identifier object priority.
[0054] As the vehicle's speed increases, the navigation system can provide the driver with a target map with a lower density of marked objects. At this time, based on the priority of the marked objects, it can select to hide some of the lower priority marked objects within the original map range, and retain another part of the higher priority marked objects in the original map, to obtain a target map with reduced display density presented to the driver.
[0055] Furthermore, the priority of the marked objects can be determined based on how useful they are to the driver. By presenting high-priority marked objects in the target map and hiding low-priority marked objects that are less useful to the driver, the efficiency of the driver in viewing the map can be improved, helping the driver to find useful information as soon as possible, reducing the time the driver spends looking at the map, and improving road safety.
[0056] As an optional embodiment, in order to obtain the priority of the identification object corresponding to the vehicle, the vehicle's usage scenario can be obtained first, and then the priority of the identification object corresponding to the vehicle can be determined based on the usage scenario.
[0057] Based on this optional embodiment, priority rules that are more in line with the driver's driving scenario can be determined first, so that the target objects in the subsequently generated target map are the objects related to the driver's driving scenario, thereby improving the efficiency of the driver's map retrieval.
[0058] As an optional embodiment, the vehicle's usage scenario can be obtained through at least one of the following methods:
[0059] Method 1: Display a scenario selection interface, respond to the target command received by the scenario selection interface, and determine the vehicle usage scenario based on the target command. Optionally, the scenario selection interface can be displayed on the vehicle's central control system display screen, or on a terminal device that displays the original map and the target map. The scenario selection interface can be set to select from multiple optional vehicle usage scenarios and scenario buttons, allowing the driver to select the usage scenario that meets their needs based on their own judgment and generate the target command. Optionally, vehicle usage scenarios can include types such as heading to a destination, driving, sightseeing, parking, or conducting financial business. The above vehicle usage scenarios are only illustrative examples and do not constitute a limitation of this disclosed solution.
[0060] Method 2: Collect vehicle location information, determine the corresponding usage area based on the location information, obtain second-level identifiers within the usage area, and finally determine the usage scenario based on the second-level identifiers. In this method, vehicle location information can be collected via GPS signals. The usage area can be selected according to the driver's needs. For example, when the driver enters the destination for this driving trip into the navigation map, a certain geographical area around the destination can be selected as the usage area, and the usage scenario can be determined based on this. Alternatively, the area between the departure point and the destination can be designated as the usage area. Based on the types of multiple second-level identifiers within the usage area and the number of second-level identifiers matching each type, the usage scenario for this driving trip can be formulated. For example, when a large proportion of the second-level identifiers in the usage area are financial points of interest, the usage scenario for this trip can be formulated as conducting financial business.
[0061] As an optional embodiment, the target identifier object is determined from the identifier object set based on the display density and identifier object priority, which can be achieved by: selecting a first identifier object from the identifier object set based on the identifier object priority; and selecting the target identifier object from the first identifier object based on the display density.
[0062] Based on the method provided in this optional embodiment, it is possible to first exclude the first identification objects within the geographical range of the original map that do not meet the driver's priority requirements for identification objects, select the first identification objects that meet the requirements, and then control the number of the first identification objects according to the target display density requirements, filter out some of the first identification objects, obtain the target identification objects, and control the density of the target identification objects obtained by dividing the number of target identification objects by the size of the target map to match the above-mentioned target display density.
[0063] As an optional embodiment, when selecting the first identifier object from the identifier object set according to the identifier object priority, the following method can be adopted: determine at least one conflict subset from the identifier object set, wherein each subset of the conflict subset includes at least two identifier objects from the identifier object set and there is a geographical overlap between the at least two identifier objects; select a priority identifier object from each subset of the conflict subset according to the identifier object priority; and select the priority identifier object and the identifier objects in the identifier object set other than the conflict subset as the first identifier object.
[0064] This optional embodiment solves the problem of unclear display caused by overlapping marker objects in the display interface. For example, when a marker object is a point of interest (PO), different floors of the same building within the original map's geographical area may have different businesses. In the navigation map, each business is a PO, and thus several POs can be marked at the building's location on the map. If all these POs are marked on the navigation map, they will obscure each other. This optional embodiment divides overlapping marker objects into a conflict subset, and then selects the highest-priority marker object from each conflict subset based on the marker object's priority, resulting in multiple high-priority marker objects. These high-priority marker objects, along with marker objects not included in the conflict subset, can then be used as the first marker object, ensuring that all first marker objects are within the original map's geographical area and do not conflict with each other.
[0065] Figure 3 This is a schematic diagram of point-of-interest (POI) anti-collision processing provided according to optional embodiments of this disclosure, such as... Figure 3 As shown, when the identified object is a point of interest (POI) on the map, without anti-collision processing, the map will display multiple overlapping and interfering POIs. This makes it very difficult for the driver to view the map, as they cannot obtain useful information about the overlapping POIs. If the driver zooms in to observe carefully, there will be a significant driving safety risk. The state of POIs after classifying geographically overlapping POIs into a conflict subset and processing them based on the priority of the identified object is shown in the figure. At this point, there are no overlapping POIs on the map, and the map retains only useful information that is clear and easy for the driver to understand.
[0066] Figure 4 This is a flowchart of a target map generation process provided according to an optional embodiment of this disclosure, such as... Figure 4 As shown, the original map can be adjusted to the target map using the following steps:
[0067] First, vehicle speed and location information are collected. Optionally, vehicle speed information can be obtained through the vehicle's speed sensor, and location information can be obtained based on the vehicle's GPS signal. Second, the vehicle's speed is parsed from the speed information, and the corresponding road and environmental information is determined based on the location information. To determine the road information, the road ID currently being traveled by the vehicle can be determined based on the location information, and then information related to that road, such as road type, can be read based on the road ID. Additionally, points of interest within a certain radius around the vehicle's current location can be obtained, and these points of interest can be analyzed to obtain environmental information. Third, a vehicle speed coefficient can be determined based on the driving speed, and a road coefficient can be determined based on the road information. Then, the display density is determined based on the vehicle speed coefficient, road coefficient, and corresponding weight values. Fourth, the usage scenario can be determined based on the environmental information, and then the priority of the labeled objects can be determined based on the usage scenario. Fifth, based on the display density and the priority of the labeled objects, target labeled objects can be selected from all labeled objects within the geographical range of the original map, ensuring that the target labeled objects meet both the display density and the labeled object priority. Finally, the initial labeled objects in the original map can be replaced with the target labeled objects to obtain a target map labeled with the target labeled objects.
[0068] Figure 4 The proposed solution addresses the following drawbacks of related technologies where the content and amount of map display information remain almost unchanged:
[0069] First, vehicles on the road pose safety risks. For drivers, finding a precise location or name on a map requires their gaze to be off the road for a certain period of time. When the information density of the map remains constant, the time the gaze is off the road can be considered fixed. In low-speed driving conditions, the emergency braking distance of a car is short, and the risk of gaze shift is relatively small. In high-speed driving conditions, the emergency braking distance of a car becomes significantly longer, posing a higher safety risk.
[0070] Secondly, drivers are more likely to take the wrong route. In high-speed driving conditions, drivers pay more attention to the road. For safety reasons, the time spent paying attention to the map screen is significantly reduced, and complex map information is more likely to cause drivers to make mistakes.
[0071] Secondly, there is a lack of contextual recommendations for drivers. Highway driving has distinct scenario characteristics (highways, urban expressways, etc.), and the map only displays the original information normally without providing any recommendations.
[0072] According to embodiments of this disclosure, a map information processing apparatus for implementing the above-described map information processing method is also provided. Figure 5 This is a structural block diagram of a map information processing apparatus provided according to embodiments of the present disclosure, such as... Figure 5As shown, the map information processing device includes: a first display module 52, an acquisition module 54, a first determination module 56, a second determination module 58, and a second display module 60. The map information processing device will be described below.
[0073] The first display module 52 is used to display the original map on the vehicle's display interface, wherein the original map includes initial marker objects;
