The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The terms "including" and "having," and any variations thereof in the description and claims of this application and the above-described drawings, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed.
In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.
Next, a head-mounted display device for assisting navigation provided by an embodiment of the present application is described in detail. Fig. 1 is a schematic structural diagram of a head-mounted display device for assisting navigation according to an embodiment of the present disclosure, where the head-mounted display device includes a processor 11, a wireless communication component 12, a satellite positioning component 13, an image collector 14, and a storage component 15; the storage unit 15 stores therein a map and a theoretical environment image.
The wireless communication part 12 determines the position of the intelligent terminal device in the set reference coordinate system through the network signal.
The wireless Communication section 12 may employ a 4G (the 4Generation Mobile Communication Technology, fourth Generation Communication Technology) module or a 5G (5 th-Generation Mobile Communication Technology, fifth Generation Communication Technology) module. In the embodiment of the present application, the specific form of the wireless communication section 12 is not limited.
The satellite positioning section 13 determines the position of the head-mounted display device through two-way communication with a satellite.
In consideration of practical application, the signal strength of the network signal and the positioning signal is easily affected by the external environment, for example, in a mountain forest with luxuriant vegetation, the signal strength is often weak due to the shielding of vegetation, so that accurate positioning is not facilitated.
In practical applications, the processor 11 may be connected to the wireless communication unit 12 and the satellite positioning unit 13, respectively, and the processor 11 may detect the strength of the network signal received by the wireless communication unit 12 and detect the strength of the satellite signal received by the satellite positioning unit 13. In case the signal strength of the network signal or the positioning signal does not meet the set signal strength requirement, the satellite positioning component 13 may be controlled to perform a periodic positioning at set time intervals and mark positioning data on the map.
The signal strength requirements may include a signal strength minimum, and in particular implementations, respective corresponding signal strength minimum values may be set for the network signal and the positioning information. In the case where the signal strength of the network signal is smaller than the corresponding signal strength minimum value, or the signal strength of the positioning signal is smaller than the corresponding signal strength minimum value, the cycle time for the satellite positioning section 13 to perform positioning may be reduced.
The value of the set time interval may be smaller than the value of the original cycle time of the satellite positioning component 13. For example, the cycle time of the satellite positioning is originally 5 minutes, the set time interval may be 1 minute, the satellite positioning unit originally performs positioning once every 5 minutes, and the satellite positioning unit may perform positioning once every 1 minute if the signal strength is weak.
The positioning data may comprise positioning coordinates and a positioning time.
The satellite positioning component 13 is deployed on the head-mounted display device, the positioning frequency of the head-mounted display device is increased by reducing the cycle time of the positioning performed by the satellite positioning component 13, and even if the positioning fails due to weak signals, the user can deduce the current approximate position of the user based on the positioning coordinates and the positioning time of the markers, so that the off-line map can be used for determining the path to be traveled.
The processor 11 is connected to the image collector 14, and is configured to obtain an actual environment image of an environment where the head-mounted display device is currently located, which is collected by the image collector 14; and matching the actual environment image with the theoretical environment image to determine the direction identifier, so that a user can determine a feasible route according to the map marked with the positioning data and the direction identifier.
In this embodiment of the application, the theoretical environment image may be an image of an environment where the user is currently located, and a direction of the environment where the user is currently located, for example, a direction of the south, the west, and the north, etc., is identified according to the theoretical environment image.
Taking the night environment as an example, the theoretical environment image may include a theoretical starry sky image; accordingly, the actual environment image includes an actual starry sky image.
In a specific implementation, the processor 11 may match the acquired actual starry sky image with the theoretical starry sky image to determine a target starry image included in the actual starry sky image and used for directing the direction; the target star may include a north star or a south cross, among others.
The north star is used to indicate the direction of true north and the south cross is used to indicate the direction of true south.
The processor 11 can determine the direction according to the target star image, and can display a direction identifier on a visual interface of the head-mounted display device in order to facilitate the user to know the direction of the current environment.
The head mounted display device may be AR glasses, AR helmets, and the like. Taking AR glasses as an example, the direction markers may be displayed on the lenses of the AR glasses.
The direction mark can adopt an arrow to point to the east, south, west, north and other directions, or show which direction the front of the user is in a text form. In the embodiment of the application, the specific form of the direction identifier is not limited, so that a user can intuitively know the direction of the current environment.
Taking the daytime environment as an example, the theoretical environment image may include a plant image.
Considering that different plants have different growth conditions in different directions, the direction can be determined based on the growth difference of the plants. For example, the south-facing plants tend to flourish more strongly than the north-facing plants.
In a specific implementation, the processor 11 may match the obtained actual environment image with the plant image to determine a target plant included in the actual environment image; and determining the direction according to the plant type and the branch and leaf density of each target plant in the actual environment image, and displaying the direction identification on a visual interface of the head-mounted display equipment.
The plant categories may be used to distinguish different plants, and the plant categories may include sunny plants and juveniles. Wherein the content of the first and second substances, the plant of the yang-exposing type may include sunflower, herba Lagenariae Seu Calvatiae, canna, and rhizoma Polygoni Cuspidati.
Plant images of different plant types can be stored in the storage part 15 of the head-mounted display device, and by matching the collected actual environment image with the plant images stored in advance, which types of plants are contained in the actual environment image can be determined.
Since the branch and leaf density of plants in different plant categories are different in different directions, after the plant category is determined, the direction can be determined based on the branch and leaf density of the plant.
Taking AR glasses as an example, the direction markers may be displayed on the lenses of the AR glasses.
In order to facilitate the user to intuitively know which plants are contained in the current environment, the processor 11 may display the category information of the target plants on a visual interface of the head-mounted display device, for example, display the plant categories corresponding to the plants in different positions on the lenses of the AR glasses.
Considering that animals are often present in mountain areas, some animals may be aggressive or toxic, and the user may threaten the safety of the user by touching the animals by mistake.
Some animals have a color similar to that of plants in mountain forests, e.g., snakes and insects. The user often cannot accurately recognize the information by the naked eye alone. Even if the user is able to identify the presence of an animal, the specific category of the animal may not be known.
Therefore, in the embodiment of the present application, the theoretical environment image may include an animal image, and the processor 11 may match the acquired actual environment image with the animal image to determine the target animal included in the actual environment image; and displaying the category information of the target animal on a visual interface of the head-mounted display device.
Taking AR glasses as an example, for example, animal categories corresponding to animals at different positions may be displayed on lenses of the AR glasses. For animals with aggressivity or toxicity, prompt messages can be displayed on the lenses of the AR glasses, so that the attention of a user can be attracted, and the danger caused by the fact that the user touches the animals by mistake is avoided.
According to the technical scheme, the head-mounted display equipment for assisting navigation comprises a processor, a wireless communication part, a satellite positioning part, an image collector and a storage part; the storage unit stores a map and a theoretical environment image. The wireless communication section relies on network signals to perform positioning functions, and the satellite positioning section relies on positioning signals to perform positioning functions. The processor is respectively connected with the wireless communication component and the satellite positioning component, under the condition that the signal strength of the network signal or the positioning signal does not meet the set signal strength requirement, the network signal or the positioning signal of the environment where the head-mounted display device is located is influenced, and the received signal is weak, at the moment, the processor can control the satellite positioning component to perform periodic positioning according to the set time interval, and mark positioning data on a map. By marking the positioning data on the map, the user can deduce the current approximate position of the user according to the positioning data marked on the map when the positioning of the network signal and the positioning signal fails, thereby determining the walking route. The processor is connected with the image collector and can acquire an actual environment image of the environment where the head-mounted display device is currently located, wherein the actual environment image is acquired by the image collector; the actual environment image is matched with the theoretical environment image, so that the direction of the current environment of the head-mounted display device can be determined. In order to facilitate the user to intuitively know the direction, a direction mark can be set. The user can determine a feasible route according to the map marked with the positioning data and the direction identifier. In the technical scheme, the head-mounted display device marks positioning data on the map in time when detecting that the signal is weak, so that a user can know the self walking route conveniently. And based on the analysis of the actual environment image, the direction of the environment in which the user is currently located can be determined. Even if the signal is unstable or the positioning fails, the reference route and the direction can be provided for the user, so that the user is prevented from losing the direction in the current environment, and the navigation reliability of the user in the mountain area is effectively improved.
In the moving process of the head-mounted display device, a region with a stronger signal may move to a region with a weaker signal, so that the positioning is inaccurate or fails. Therefore, in the embodiment of the present application, the time interval at which the satellite positioning component performs positioning can be adjusted based on the movement situation of the head-mounted display device and the change situation of the signal strength.
In a specific implementation, an acceleration sensor may be disposed on the head-mounted display device. The acceleration sensor is connected with the processor 11, and can transmit the acquired acceleration data of the head-mounted display device to the processor 11.
The processor 11 is used for determining the motion state of the head-mounted display device according to the acceleration data; in the case that the head mounted display device is in a moving state and the duration of time during which the signal strength of the network signal or the positioning signal does not meet the set signal strength requirement reaches the set time threshold, the satellite positioning component 13 may be controlled to perform periodic positioning at set time intervals.
In the embodiment of the present application, a prompting component connected with the processor 11 may be disposed on the head-mounted display device.
In the case that the head-mounted display device is in a moving state and the duration of the time that the signal strength of the network signal or the positioning signal does not meet the set signal strength requirement reaches the set time threshold, the processor 11 may control the prompting component to perform the alarm prompting.
The value of the duration may be set based on the actual demand, for example, it may be set to 5 minutes.
The head-mounted display device is in a moving state in 5 continuous minutes, the strength of the positioning signal of the head-mounted display device does not meet the set signal strength requirement, the situation that the user is moving to the area with the weaker signal and does not tend to move to the area with the stronger signal is indicated, and in order to avoid that the user always moves to the area with the weaker signal, the processor can control the prompting component to give an alarm prompt so as to attract the attention of the user.
The prompting component can be a voice player or a vibrator, etc.
Considering that in practical applications, the user may be going to visit alone, in order to increase the interest of the journey, the processor 11 of the head-mounted display device may control the visual interface of the head-mounted display device to play the set virtual image.
The virtual image may be an image of a person familiar to the user, or an image of a cartoon character liked by the user. Through playing the virtual image on visual interface, can increase the enjoyment of journey to when visiting the region that some scenery are close or the region that the user is not interested in, the user can watch the virtual image, avoids the user to produce aesthetic fatigue.

In some areas with more vegetation coverage or complex terrain, the signal strength of the network signals and the positioning signals are susceptible to being weakened.
The signal stability of the positioning signal is higher compared to the network signal. In the embodiment of the present application, in order to avoid the situation that the signal strength suddenly weakens or disappears in a short time to cause the positioning failure, the satellite positioning component may be controlled to perform the periodic positioning according to the set time interval and mark the positioning data on the stored map when the signal strength is detected not to meet the set signal strength requirement. The value of the set time interval is smaller than the time interval of the original satellite positioning component for periodic positioning.
The positioning data may comprise positioning coordinates and a positioning time.
By positioning more frequently and marking the positioning data on the map, even if the subsequent signal is weaker and cannot be positioned, the user can still deduce the current approximate position according to the positioning data marked on the map, so that the subsequent travelling path is determined by using the off-line map.
