In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
In some environments with poor signals, when the navigation function is realized by using signals such as GPS, bluetooth, WIFI signals, 2G/3G/4G/5G, etc., the situation with poor accuracy of navigation may occur.
In the embodiment of the application, the current position of the user, namely the first starting point position, is obtained by acquiring the image information of the current environment of the user and identifying the first marker information in the image information, namely, signals such as GPS, Bluetooth, WIFI signals and 2G/3G/4G/5G are not required to be utilized when the position of the user is positioned; in addition, when navigation is performed, navigation is performed by using the navigation route information carrying the second marker information, and signals such as a GPS, a Bluetooth, a WIFI signal and a 2G/3G/4G/5G signal do not need to be used, so that in environments with poor signals such as the GPS, the Bluetooth, the WIFI signal and the 2G/3G/4G/5G signal, accurate navigation can still be achieved through the acquired navigation route information carrying the second marker information, and the technical problem that the navigation accuracy is influenced by environmental interference of the navigation signal is solved.
Fig. 1 is a schematic diagram illustrating a first implementation flow of a navigation method provided by an embodiment of the present application, where the method is applied to a terminal and can be executed by a navigation device configured on the terminal, and the navigation device is suitable for a situation that an environment with poor communication signals needs to be implemented to improve navigation accuracy. The terminal comprises terminal equipment such as a smart phone, a tablet personal computer, a Personal Digital Assistant (PDA), a learning machine and an electronic watch. The navigation method may include steps 101 to 104.
In step 101, image information of an environment where a user is currently located is acquired, and first marker information in the image information is identified.
In practical applications, when a user needs to acquire navigation data, a start position and an end position are generally acquired first, so as to determine navigation route information from the start position to the end position according to the start position and the end position.
In the embodiment of the application, the current position of the user is obtained by acquiring the image information of the current environment of the user and identifying the first marker information in the image information, so that the mobile terminal can still accurately position the current position of the user in the environment with poor communication signals and no communication signals or in the environment with indoor environment interference on the communication signals and greatly reduced navigation accuracy.
Identifying first marker information in the image information comprises performing target detection on the image information, classifying a foreground and a background at a pixel level, removing the background, and retaining one or more target objects, namely one or more pieces of first marker information.
In some embodiments of the present application, the method for detecting the target includes performing target detection on the image information by using a trained convolutional neural network model, and obtaining a detection result.
The trained convolutional neural network model is obtained by training according to each sample picture in the database and the detection result corresponding to each sample picture, wherein the detection result corresponding to each sample picture is used to indicate all target objects contained in the sample picture, that is, all first marker information, and the first marker information may be target objects which can play a role in identification and do not move frequently, for example, fixed buildings in channels such as railings and windows, and ornaments, characters and patterns which do not move frequently in the channels, the characters and patterns may be specific characters and patterns printed on a wall, and the specific characters and patterns printed on the wall may be characters or patterns in a billboard of a merchant, and the like.
Optionally, the training step of the convolutional neural network model may include: acquiring a sample image and a detection result corresponding to the sample image; and detecting the sample image by using a convolutional neural network model, adjusting parameters of the convolutional neural network model according to a detection result until the adjusted convolutional neural network model can detect all target objects in the sample image, or the accuracy of the target objects in the sample image is detected to be greater than a preset value, and taking the adjusted convolutional neural network model as a trained convolutional neural network model. The parameters of the convolutional neural network model may include the weight, deviation, and coefficient of the regression function of each convolutional layer in the convolutional neural network model, and may further include a learning rate, iteration times, the number of neurons in each layer, and the like. At present, the conventional Convolutional Neural Network models include an RCNN (region based Convolutional Neural Network) model, a Fast-RCNN model, and the like. The fast-RCNN model is evolved on the basis of the RCNN model and the fast-RCNN model, and compared with the RCNN model and the fast-RCNN model, the fast-RCNN model still cannot realize real-time detection of the target object, but has higher target detection precision and target detection speed compared with the RCNN model and the fast-RCNN model, so that in some embodiments of the application, the fast-RCNN model is preferred to the convolutional neural network model.
It should be noted that the above target detection method is only exemplified herein, and is not meant to limit the scope of the present application, and other methods capable of achieving target detection are also applicable to the present application, and are not listed herein.
That is to say, in the embodiment of the present application, after the image information of the current environment where the user is located is obtained, and the first marker information in the image information is identified, the first starting point position of the user may be determined through the first marker information.
In some embodiments of the present application, determining a first starting point location from the first marker information comprises: and matching the first marker information with third marker information carried in a pre-stored navigation map, and taking a position corresponding to the third marker information successfully matched with the first marker information as the first starting point position.
For example, a user picks up a mobile terminal such as a mobile phone and the like provided with a camera to photograph surrounding objects, so as to complete acquisition of image information of the current environment of the user, and then identifies first marker information in the image information, matches the first marker information with third marker information carried in the pre-stored navigation map, and takes a position corresponding to the third marker information successfully matched with the first marker information as the first starting point position, so as to determine the current position of the user by using the first marker information and the navigation map.
The pre-stored navigation map may be a pre-acquired offline navigation map, the navigation map may be a video navigation map composed of a plurality of picture frames, and the navigation map carries third marker information. Under the conditions that the communication signal is weak and the communication signal is absent, or the navigation accuracy is greatly reduced when the communication signal is interfered by an indoor environment, the current position of the user can be determined by acquiring the image information of the current environment of the user, and matching the first marker information in the image information with the third marker carried in the off-line navigation map acquired in advance.
In step 103, the end position input by the user is obtained.
In practical applications, when a user needs to acquire navigation data, a start position and an end position generally need to be acquired first, so as to determine navigation route information from the start position to the end position according to the start position and the end position.
In the embodiment of the application, the acquiring of the destination position input by the user comprises the step that the user inputs the destination position to the mobile terminal in a voice or text input mode, or the destination position is directly input in a navigation application interface by selecting the map position in the navigation map.
After the current position (first starting point position) of the user and the end position input by the user are obtained, a navigation path from the first starting point position to the end position can be obtained through calculation according to the used passing path between the first starting point position and the end position, and second marker information related to the navigation path is arranged at the corresponding position of the navigation path.
In the embodiment of the application, the current position of the user, namely the first starting point position, is obtained by acquiring the image information of the current environment of the user and identifying the first marker information in the image information, so that GPS, Bluetooth, WIFI signals, 2G/3G/4G/5G signals and the like are not required to be utilized in the user position location; in addition, when navigation is performed, navigation is performed by using the navigation route information carrying the second marker information, and signals such as a GPS signal, a Bluetooth signal, a WIFI signal and a 2G/3G/4G/5G signal do not need to be used, so that accurate navigation can be still achieved through the acquired navigation route information carrying the second marker information in environments with poor signals such as the GPS signal, the Bluetooth signal, the WIFI signal and the 2G/3G/4G/5G signal.
In some embodiment modes of the present application, as shown in fig. 2, the step of matching the first marker information with third marker information carried in a pre-stored navigation map and taking a position corresponding to the third marker information successfully matched with the first marker information as the first starting point position may include: step 201 to step 202; so as to reduce the data volume of the first marker information matched with the third marker information carried in the pre-stored navigation map.
In step 201, a second starting point position is obtained according to the received wireless signal, where the second starting point position is used to indicate a position where the user is most likely to be located currently.
Since accurate continuous navigation may not be achieved only in the case of poor signals such as GPS, bluetooth, WIFI signals, and 2G/3G/4G/5G signals, but coarse positioning of the starting point position may be achieved, a second starting point position may be obtained according to the received wireless signal, where the second starting point position is used to indicate a position where the user is most likely to be currently located.
In step 202, the first marker information is matched with third marker information within a preset distance range from the second starting point position, and a position corresponding to the third marker information successfully matched with the first marker information is taken as the first starting point position.
After the second starting point position is obtained, the matching range of the first marker information and the third marker information can be narrowed according to the second starting point position, and the first marker information is matched with the third marker information within a preset distance range from the second starting point position, so that the accurate current position of the user is obtained.
In an embodiment of the present invention, the matching range between the first marker information and the third marker information is reduced by screening out third marker information within a preset distance range from the second starting point position, and matching the first marker information with the third marker information within the preset distance range from the second starting point position.
In some embodiments of the present application, the preset distance range may be a circular range with a radius of a preset distance, and the preset distance may be determined according to an actual application scenario, for example, if the application scenario is indoor navigation, since there are more third markers within a unit distance (e.g., 10m) of the indoor navigation, the preset distance may be set to be smaller, for example, set to 100m to 300 m; if the application scenario is outdoor navigation, since the number of the third markers involved is small within a unit distance (e.g., 10m) of the outdoor navigation, the preset distance may be set to be larger, for example, 300m to 1000 m.
Optionally, if the first marker information is matched with third marker information within a preset distance range from the second starting point position, and the third marker information successfully matched with the first marker information is not matched, the preset distance range is expanded by one time until the preset distance range is expanded to a maximum preset multiple.
The maximum preset multiple can be determined according to an actual application scene, for example, if the application scene is indoor navigation, the maximum preset multiple can be set to be larger, for example, 5 to 10 times; if the application scene is outdoor navigation, the maximum preset multiple may be set to be smaller, for example, set to be 3-5 times.
The first marker information contained in the image information of the environment where the user is currently located may include a plurality of pieces of sub-marker information, and the third marker information carried in the navigation map stored in advance may also include a plurality of pieces of sub-marker information, and it is possible that the sub-marker information in the first marker information is successfully matched with the plurality of pieces of sub-marker information in the third marker information, so that the current location of the user cannot be really determined.
Therefore, in some embodiment modes of the present application, the matching the first marker information with third marker information carried in a navigation map stored in advance, and taking a position corresponding to the third marker information successfully matched with the first marker information as the first starting point position includes: matching the sub-marker information in the first marker information with sub-marker information in third marker information in sequence, screening out third marker information uniquely matched with the first marker information, and taking a position corresponding to the third marker information uniquely matched with the first marker information as the first starting point position.
For example, matching a first one of the first marker information with all of the sub-marker information in the third marker information; and if only one piece of sub-marker information in the third marker information is successfully matched with the first sub-marker information in the first marker information, taking the position corresponding to the third marker information successfully matched with the first sub-marker information in the first marker information as the first starting point position.
If there is a successful match of sub-marker information of the plurality of third marker information with the first sub-marker information of the first marker information, matching all sub-markers in each third marker information except the sub-marker successfully matched with the first sub-marker information in the first marker information with the second sub-marker information in the first marker information, if the sub-marker information in the plurality of third marker information is successfully matched with the second sub-marker information in the first marker information, continuing the next round of matching until there is only one successful matching of the sub-marker information in the third marker information with the sub-marker information in the first marker information, and taking the position corresponding to only one third marker information which is successfully matched with the first marker information as the first starting point position.
In the above embodiments, after the image information of the current environment of the user is acquired and the first marker information in the image information is identified, the step of determining the first starting point position according to the first marker information is all obtained by the mobile terminal through self-processing, which may consume more data processing resources of the mobile terminal, and therefore, in some embodiments of the present application, as shown in fig. 3, the step of determining the first starting point position according to the first marker information may include steps 301 to 303.
In step 301, a second starting point position is obtained according to the received wireless signal, and a starting point identifier is added to a corresponding position of a map displayed on a navigation application interface, where the second starting point position is used to indicate a position where a user is most likely to be located currently.
Since accurate continuous navigation may not be achieved only in the case of poor signals such as GPS, bluetooth, WIFI signals, and 2G/3G/4G/5G signals, but coarse positioning of the starting point position may be achieved, a second starting point position may be obtained according to the received wireless signal, where the second starting point position is used to indicate a position where the user is most likely to be currently located.
In step 302, a movement instruction triggered by the user on the navigation application interface to the starting point identifier is obtained, and the starting point identifier is moved.
In step 303, the position corresponding to the moved start point identifier is determined as the first start point position.
For example, as shown in fig. 4, the mobile terminal acquires a second starting point position according to the received wireless signal, adds a starting point identifier 41 to a corresponding position of a map displayed on the navigation application interface 40, then, after the user views surrounding markers through eyes, finds a position where the mobile terminal is located around the starting point identifier 41 on the map displayed on the navigation application interface, and after finding a position where the mobile terminal is located 42 on the map displayed on the navigation application interface, moves the starting point identifier 41 to the position 42, so that the mobile terminal determines the position corresponding to the moved starting point identifier as the first starting point position, thereby reducing the data processing amount of the mobile terminal for calculating the first starting point position.
Optionally, as shown in fig. 5, in some embodiments of the present application, in the step 104, navigating according to the navigation route information includes: step 501 to step 503.
In step 501, displaying the navigation route information in a navigation application interface in a text description mode;
in step 502, according to a navigation starting instruction triggered by a user on a navigation application interface, current movement direction information and current movement distance information of the user are acquired;
in step 503, the current movement direction information and the current movement distance information of the user are fitted to the navigation path in the navigation route information described in the text, and the text description matched with the current movement direction information and the current movement distance information of the user is highlighted on the navigation application interface.
For example, as shown in fig. 6, navigation route information 61 like "go straight from the current position by about 20m, see a left turn of a marker a, go straight by about 50m, have a marker B on the right hand side, go straight by about 10m, have a marker C on the right hand side, go straight by about 100m, and have a destination on the left hand side" is displayed in the form of text description on the navigation application interface 60.
Because the mobile terminal cannot be positioned by means of the communication signal under the condition of poor communication signal, when navigating, the current movement direction information and the current movement distance information of the user are required to be acquired so as to fit the current movement direction information and the current movement distance information of the user with the navigation path in the text description navigation route information, and the text description 'straight line 20 m' matched with the current movement direction information and the current movement distance information of the user is highlighted on the navigation application interface.
It should be noted that the manner of highlighting the text description matching with the current movement direction information and the current movement distance information of the user may be a manner of using a different font color, a different font, a different size and/or bolding the text description.
Optionally, in some embodiments of the present application, in the step 104, the obtaining navigation route information according to the first starting point position and the ending point position includes: acquiring a passing path communicating the first starting point position and the end point position; and calculating a navigation path from the first starting point position to the end point position according to the passing path, and obtaining navigation route information containing the navigation path.
In this embodiment, the navigation route information includes a navigation path and second marker information associated with a position corresponding to the navigation path, so that after the navigation path from the first starting point position to the end point position is calculated according to the transit path, the second marker information associated with the position corresponding to the navigation path is further acquired, and then the navigation route information including the navigation path and the second marker information associated with the position corresponding to the navigation path is acquired.
When the navigation paths from the first starting points to the end points are calculated, the route a, the route b, the route c and the route … … can be marked on the navigation application interface according to the distance sequence of the navigation paths for the user to select.
Optionally, in some embodiments of the present application, in the step 104, acquiring navigation route information according to the first starting point position and the ending point position, further includes: displaying a starting point identifier corresponding to the first starting point position, an end point identifier corresponding to the end point position and a passing path communicating the first starting point position and the end point position at a corresponding position of a map displayed on a navigation application interface; and receiving a path planning operation from a first starting point position to a final position triggered by a user on a map displayed on the navigation application interface, acquiring a navigation path according to the path planning operation, and acquiring navigation route information containing the navigation path.
That is to say, after a first starting point position and an end point position are obtained, the mobile terminal displays a starting point identifier corresponding to the first starting point position and an end point identifier corresponding to the end point position on the navigation application interface, and displays all traffic paths communicating the first starting point position and the end point position, so that a user can directly perform path planning on a map displayed on the navigation application interface as required.
The first starting point position and the end point position form a business circle, the time from the first starting point position to the end point position is abundant, and if a user wants to stroll from the first starting point position to the end point position, a path from the first starting point position to the end point position can be planned according to a strolling route.
In the embodiment of the application, the navigation path can be independently planned by the user, so that the navigation path can be personalized more, and the personalized requirements of the user can be met more.
