All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application are within the scope of the protection of the present application.
The terms "first," "second," and the like in the description of the present application, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. In addition, "and/or" in the specification means at least one of the connected objects, and the character "/", generally means a relationship in which the associated objects are one kind of "or".
The navigation method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 shows a flowchart of steps of a navigation method according to an embodiment of the present application, the method being performed by an electronic device, the method comprising:
step 101, a first input of a user is received.
In this step, the first input may be an input of a fixed key of the electronic device by the user, a specific gesture input by the user, a pressing input of the electronic device by the user, or the like.
For example, as shown in fig. 4, an input when the user presses the power key PU1 of the electronic device is taken as a first input by the user. Of course, the first input may also be implemented by the user pressing other fixed keys, which is not limited in the embodiment of the present application.
Step 102, responding to a first input, displaying a shooting preview interface, and displaying initial path information in the shooting preview interface; wherein the initial path information is generated based on the initial location information and the real-time location information of the electronic device.
In this step, initial position information of the electronic device may be first acquired, and after the electronic device responds to the first input, a shooting preview interface is displayed on a display screen of the electronic device, and real-time position information of the electronic device is continuously acquired, so as to generate initial path information according to the initial position information and the real-time position information of the electronic device. Wherein the initial path information indicates a corresponding initial path.
In this embodiment of the present application, the shooting preview interface may be a preview interface of a camera program when shooting an image or a video, for example, a user may synchronously display initial path information during a process of recording the video in real time; the initial path information may also be displayed during the picture taking process. The initial path information may be displayed in a form of a small window superimposed in the photographing preview interface, and a user may adjust the size and display position of the window based on the need. The initial path information can be displayed in the shooting preview interface with a certain transparency, so that the image content in the shooting preview interface is prevented from being blocked.
For example, as shown in fig. 5, in response to the first input, an image display area b3 and a route display area a3 exist on a photographing preview interface of the display screen, a photographed image may be displayed through the image display area b3, an initial route corresponding to the initial route information may be displayed in the route display area a3, or a current traveling direction may be displayed in the display area b3, and the current traveling direction may be indicated by an arrow.
Step 103, receiving a second input from the user.
In this step, the second input may be an input of a fixed key of the electronic device by the user, a specific gesture input by the user, a pressing input of the electronic device by the user, or the like.
For example, as shown in fig. 4, when the user clicks the power key PU1 again, the operation of clicking the power key PU1 by the user may be regarded as the second input by the user.
Step 104, responding to the second input, displaying a navigation route; the navigation route is generated based on the initial path information, and the navigation route is used for indicating to return to an initial position corresponding to the initial position information.
In this step, the electronic device stops shooting the image in response to the second input, and displays the navigation route on the display screen of the electronic device. The navigation route is a route obtained by processing the initial path information, for example, the original initial path may be shortened, so that the user can quickly realize the return. The navigation route is used for indicating the initial position of the electronic equipment corresponding to the returned initial position information. The navigation route not only can navigate the user on the ground, but also can navigate the user in an underwater scene or an air scene. It should be noted that, when the electronic device responds to the second input, the image may be continuously captured and the navigation route may be displayed, so that the normal capturing action is not affected.
For example, as shown in FIG. 5, when the user clicks the power key again, the display interface of the electronic device automatically jumps from FIG. 5 to the display interface shown in FIG. 6. Fig. 6 is a schematic diagram of an interface after model entry in the embodiment of the present application, as shown in fig. 6, after the image acquisition is stopped, a selection window a4 is displayed on the display screen, the display content in the selection window a4 is "entry ended", whether a navigation route is displayed, and two option buttons of "yes" and "no" are displayed, and when the user selects "yes" or "no", the corresponding operation is performed. Wherein clicking on both the yes and no option buttons may be accomplished by pressing the display directly, by clicking on a virtual key or by pressing an entity key, e.g., by pressing the up volume key to select the yes option button and by pressing the down volume key to select the no button. If the user clicks the yes option button, the electronic device responds to the input corresponding to the yes option button, and the display screen interface shown in fig. 6 automatically jumps to the display screen interface shown in fig. 7 so as to display the navigation route L2 on the display screen of the electronic device, so as to guide the user to return. If the user clicks the No button, the navigation route is not displayed, and the shooting preview interface can be continuously displayed.
In the embodiment of the application, under the condition that the first input of the user is received, the electronic equipment responds to the first input, initial path information generated based on initial position information and real-time position information of the electronic equipment is displayed in a shooting preview interface, the initial path information represents an active path of the user in the shooting process, the user can observe the moving direction and the moving distance of the user in real time through the initial path information, under the condition that the user needs to return, the second input of the user is received, then a navigation route indicating to return to the initial position is displayed in response to the second input, and the navigation route can be obtained by processing the initial route so as to better and faster guide the user to return. In the embodiment of the application, accurate navigation can be realized without GPS positioning, the accuracy of underwater navigation can be improved, and the safety of a user during underwater activities is ensured.
In some embodiments of the present application, before step 101, further comprising:
step 105, displaying a calibration interface, wherein the calibration interface comprises a first calibration identifier and a device identifier, the first calibration identifier indicates a calibration gesture, and the device identifier indicates a current gesture of the electronic device.
In this step, in order to ensure the accuracy of navigation, it is necessary to calibrate the electronic device for posture before entering the navigation route. The calibration interface is displayed on the display screen of the electronic device first, wherein the calibration interface comprises a first calibration identifier and a device identifier, the first calibration identifier indicates a calibration gesture, and the device identifier indicates the current gesture of the electronic device. By changing the relative positions of the first calibration mark and the device mark, the calibration of the gesture of the electronic device can be realized.
As shown in fig. 2, the electronic device includes an inertial measurement sensor 11 (Inertial Measurement Unit, IMU), and the electronic device obtains posture information of the electronic device through the IMU11, and generates a device identifier indicating a current posture of the electronic device according to the posture information of the electronic device.
An IMU is a device that integrates a plurality of sensors for measuring and monitoring acceleration, angular velocity and direction of an object. Typically, IMUs consist of accelerometers, gyroscopes, and magnetometers, which measure linear acceleration, angular velocity, and magnetic field information of an object to derive the direction and position of the object in space. The IMU is widely applied to the fields of navigation systems, aerospace, unmanned aerial vehicles, robots and the like.
As shown in fig. 4, a model input button a1 and a model import button b1 are arranged on a display screen of the electronic device, and the model input can be selected by clicking the model input button a1 on the display screen. When a user opens a shooting function of the electronic device or clicks a model input button a1 on the display screen, the user can perform shortcut operation by directly touching the display screen and through virtual keys or entity keys of the electronic device, wherein the entity keys comprise a power key PU1, a volume up key PU2 and a volume down key PU3. Fig. 3 is an interface schematic diagram of the electronic device for calibration according to the embodiment of the present application, and as shown in fig. 3, after the shooting function of the electronic device is turned on and the model is selected for input, the calibration interface is displayed on the display screen of the electronic device. At this time, the displayed calibration interface includes a first calibration mark b2 and a device mark a2, where the display parameters of the first calibration mark b2 and the device mark a2 are different, the device mark a2 is, for example, an ellipse filled with red, the first calibration mark b2 is, for example, a blue ellipse, and the device mark a2 and the first calibration mark b2 may be in other shapes or other colors. The first calibration flag b2 indicates a calibration gesture, and the device flag a2 indicates a current gesture of the electronic device.
Step 106, receiving a third input from the user to the electronic device.
In this step, since the device identifier and the first calibration identifier are used to guide the user to perform the posture calibration operation on the electronic device, in the case where the posture information of the electronic device is changed, the relative position of the device identifier and the first calibration identifier is also changed accordingly. Therefore, the third input to the electronic device by the user is, for example, an operation of performing posture calibration on the electronic device by the user.
In response to the third input, the display parameters of the device identification are updated, step 107.
In this step, the electronic device responds to the third input, acquires real-time posture information of the electronic device through the IMU11, and obtains display parameters of the device identifier representing the current posture of the electronic device according to the real-time posture information of the electronic device. The display parameters are, for example, a display position parameter, a display direction parameter, a display area parameter, and the like of the device identifier.
And step 108, displaying calibration success prompt information under the condition that the display parameters of the equipment identifier are matched with the display parameters of the first calibration identifier.
In the step, the display parameters of the equipment identifier are continuously updated until the calibration is successful under the condition that the display parameters of the equipment identifier are matched with the display parameters of the first calibration identifier, and a calibration success prompt message is displayed on the calibration interface.
For example, as shown in fig. 3, the electronic device is, for example, a mobile phone, when the display parameter of the device identifier a2 is not matched with the display parameter of the first calibration identifier b2, generating guide information c2, guiding the user to move the electronic device according to the guide information c2, so as to change the gesture of the electronic device, and generating prompt information d2 when the display parameter of the device identifier is matched with the display parameter of the first calibration identifier, where the prompt information is, for example, indicated as "calibration is successful", so as to realize completion of calibration of the electronic device. In fig. 3 (301), the guidance information c2 is indicated as "the mobile phone needs to rotate leftwards", the guidance information c2 in fig. 3 (302) is indicated as "rotate rightwards", the mobile phone orientation is changed ", and the prompt information d2 in fig. 3 (303) is indicated as" calibration is successful ". According to the guidance information c2, the user moves the electronic device until the display parameter of the device identifier a2 matches the display parameter of the first calibration identifier b2, and the blue gesture frame b2 changes to the green gesture frame b2, at which point, as shown in fig. 3 (303), the prompt information d2 indicates "calibration is successful", that is, indicates that the electronic device calibration is completed. After the electronic device calibration is completed, the calibration interface shown in fig. 3 automatically jumps to the display screen interface shown in fig. 4.
In some embodiments of the present application, step 102 includes:
and step 1021, controlling a camera of the electronic device to acquire images, and acquiring coordinate information and posture information of the electronic device corresponding to each frame of image.
In this step, as shown in fig. 2, the electronic device further includes a camera 12 and a pressure sensor 13. After the electronic device calibration is completed, the electronic device controls the camera 12 to acquire a plurality of frame images, and acquires coordinate information and posture information of the electronic device corresponding to each frame image. Wherein the coordinate information of each frame image is generated based on the pose information of each frame image and the coordinate information of the previous frame image. And the coordinate information of each frame of image corresponds to the real-time position information of the electronic equipment shooting each frame of image. The coordinate information includes plane coordinate information and depth coordinate information, and the posture information includes gyroscope data information and acceleration information.
In the step, after the electronic equipment completes the posture calibration, the initial position information and the initial gyroscope data information of the electronic equipment are acquiredWherein the initial position information includes initial plane coordinate information and initial depth coordinate information. Wherein the initial coordinates of the initial position information characterization are expressed, for example, (x 0 ,y 0 0), the pressure value of the pressure sensor is 0 when the user has not launched water on shore because the depth coordinate information is obtained from the pressure value transmitted by the pressure sensor, so the initial depth coordinate information is 0. When controlling a camera of an electronic device to acquire an image, the electronic device measures gyroscope data information and Acceleration (ACC) information of the electronic device corresponding to each frame of image through an inertial measurement sensor 11. And determining plane coordinate information of each frame of image according to the gyroscope data information, the acceleration information and the coordinate information of the previous frame of image of each frame of image. The plane coordinate information comprises longitude information and latitude information, and the plane coordinate information corresponding to the first frame image is obtained by updating the initial position information through the posture information of the first frame image.
For example, the plane coordinate corresponding to the n-1 th frame image is P n-1 ＝(x n-1 ,y n-1 ) The gyroscope data information is thatThe gesture coordinate is +.>Therefore, the plane coordinate corresponding to the nth frame image is P n ＝(x n ,y n ) The gyroscope data information is-> Acceleration information isThe gesture coordinate is +.>Wherein n is a positive integer, and the gesture coordinate is a gesture or direction of the electronic device in a three-dimensional space. The specific formula is as follows:
Wherein Δt is the time interval of image acquisition, v n-1 Indicating the corresponding speed of the n-1 frame image.
Further, the electronic device can determine depth coordinate information corresponding to each frame of image by acquiring the pressure value transmitted by the pressure sensor 13. And the coordinate axis of the depth coordinate information corresponding to each frame of image is perpendicular to the plane of the plane coordinate information.
For example, the depth coordinate information corresponding to the nth frame image is Z n The pressure value transmitted by the pressure sensor is P n Z is then n ＝cP n Where c is the conversion coefficient of the pressure value and the depth coordinate information, and is determined under the same water area.
For example, as shown in fig. 4, when the electronic device completes the gesture calibration, a prompt text c1 may be displayed on the display screen, where the prompt text c1 is, for example, "clicking a power key to start to enter a model", through the prompt text c1, a user may use the power key PU1 of the electronic device as an input to the electronic device by the user, the electronic device responds to the input, controls a camera of the electronic device to collect an image, and obtains coordinate information and gesture information of the electronic device corresponding to each frame of image, and the display screen interface shown in fig. 4 automatically jumps to the display screen interface shown in fig. 5.
Sub-step 1022 displays the initial path information in the photographing preview interface according to the coordinate information and the pose information corresponding to each frame of image.
In this step, the electronic device generates initial path information and displays the initial path information on the display screen according to the coordinate information and the posture information corresponding to each frame of the image.
For example, as shown in fig. 5, an image display area b3 and a route display area a3 exist on a photographing preview interface of a display screen, a photographed image may be displayed through the image display area b3, and an initial route and a current traveling direction corresponding to the initial route information are displayed in the route display area a 3.
In the embodiment of the application, the camera of the electronic equipment is used for collecting the images, and the initial path information is displayed in the shooting preview interface according to the coordinate information and the gesture information corresponding to each frame of image, so that the purpose of guiding the current travelling path of the user can be achieved, and the user can sense the condition of the current travelling path.
In some embodiments of the present application, after the step of displaying the shooting preview interface in step 102, the method further includes:
step 109, a fourth input is received from the user.
In this step, the user may perform a marking operation on the travel route during model entry of the electronic device or during image acquisition. The fourth input of the user can be realized by clicking a mark button on the display screen by the user or by clicking a virtual key or a physical key with mark operation input. For example, as shown in FIG. 4, the user may double-click the volume up key PU2 quickly to effect a fourth input by the user.
In step 110, in response to the fourth input, marking information is displayed in the shooting preview interface, where the marking information is used to mark the location information of the electronic device corresponding to the fourth input, and the marking information is displayed on the initial path indicated by the initial path information.
In this step, the electronic device displays one piece of mark information in the photographing preview interface each time in response to the fourth input. The marking information is used for marking the position information of the electronic equipment corresponding to the fourth input, and the marking information is displayed on the initial path indicated by the initial path information. The mark information includes position information and shape information of the mark. And under the condition that the initial path comprises the first mark information and the second mark information, the navigation route also comprises the first mark information and the second mark information, the first distance on the navigation route is smaller than the second distance on the initial path, the first distance is the navigation distance between the positions corresponding to the first mark information and the second mark information on the navigation route, and the second distance is the distance between the positions corresponding to the first mark information and the second mark information on the initial path. The navigation route is planned through the marking information, so that the route of the user returning to the initial position can be shortened, and the navigation time is saved.
As shown in fig. 7, the mark points S1, S2 … … and Sm indicated by the mark information are, for example, triangular, five-pointed star or other shaped icons, which the present application is not limited to. And (3) connecting all the marking points in a straight line to obtain a route from S1 to Sm, taking the route from Sm to S1 as a navigation route L2, and displaying the navigation route L2 on a display screen to guide a user to return to an initial position, wherein m is a positive integer, and m is the number of the marking points.
In some embodiments of the present application, after step 104, further comprising:
step 111, a fifth input is received from the user.
In the step, after the user returns to the initial position according to the navigation route, the navigation route can be exported in the storage space of the image for viewing, and the marking point represented by the marking information on the navigation route can be selected according to the requirement of the user.
In response to the fifth input, the third marking information on the navigation route is deleted or the fourth marking information is displayed on the navigation route, step 112.
In this step, the electronic device deletes the third marker information on the navigation route or adds the fourth marker information on the navigation route in response to the fifth input. The third mark information is, for example, mark information on the navigation route, and the fourth mark information is, for example, added mark information or new mark information formed by moving a mark point indicated by the existing mark information.
In other embodiments, the navigation route between two pieces of mark information may be deleted by selecting a route between two pieces of mark information, but when deleting the navigation route between two pieces of mark information, if at least one piece of mark information corresponds to the last frame of image, the navigation route between two pieces of mark information is deleted directly. If the two pieces of mark information do not exist, the coordinates of the two mark points are directly connected by a straight line, so that the purposes of simplifying a route and saving return time are achieved.
For example, as shown in fig. 8, the display screen of the electronic device includes a delete control w1, an add control w2, and a modify control w3, and the delete control w1 or the modify control w3 is clicked to delete or modify the marker information by selecting the marker information on the navigation route. The user may also select at the location of the navigation route without the tag information and add the tag information by clicking on the add control w 2.
Step 113, updating the navigation route based on the deleted third mark information or the displayed fourth mark information.
In this step, the navigation route is updated based on the deleted third flag information or the displayed fourth flag information, and a new navigation route is formed.
Fig. 12 shows a flow chart of steps of some embodiments of the present application, the method comprising:
step 201, a sixth input of a user is received.
In this step, the user may navigate the user's destination using the preset route stored in the electronic device as a navigation route.
For example, as shown in fig. 9 (901), the user selects on shore from a plurality of preset route models including an M-type three-dimensional model M1, a pacific three-dimensional model M2, an atlantic three-dimensional model M3, and the like.
Step 202, in response to the sixth input, displaying preset path information, a direction identifier, a second calibration identifier and a device identifier.
In the step, the electronic device responds to the sixth input, a preset route model selected by a user is imported, and before preset path information, direction identification, second calibration identification and device identification are displayed, the electronic device displays a first calibration identification and a device identification in a preview picture by acquiring gesture information of the electronic device, and calibrates the electronic device through the first calibration identification and the device identification.
For example, as shown in fig. 9 (902) and 9 (903), after the electronic device imports the selected preset route model, the electronic device needs to be calibrated, so the first calibration identifier b5 and the device identifier a5 are generated on the display screen interface. And calibrating the electronic equipment through the first calibration mark b5 and the equipment mark a5, and moving the electronic equipment according to the prompt information c5 displayed on the display screen until the display parameters of the first calibration mark b5 and the display parameters of the equipment mark a5 are matched, thereby completing the calibration of the electronic equipment. The prompt information c5 is, for example, "rotate and translate the mobile phone, calibrate the initial position".
In some embodiments of the present application, after the electronic device completes calibration, the preset path information, the direction identifier, the second calibration identifier, and the device identifier are displayed on the display screen according to the preset route model. The direction identifier indicates a navigation direction of the electronic device, the second calibration identifier indicates a calibration gesture associated with the preset path information, and the device identifier indicates a current gesture of the electronic device. The second calibration mark may be the same as or different from the first calibration mark.
For example, as shown in fig. 9 (903), the electronic device displays a corresponding preset path L3 in the route display area d5 according to the preset route model. And the direction mark f5 is displayed, the direction mark f5 is displayed in a fixed area of the display screen, and the direction mark f5 is, for example, a three-dimensional object model. As shown in fig. 13, the direction indicator f5 is a shark model, and because the shark model is a three-dimensional object model, the user can feel the travelling direction more intuitively and truly on the display screen, and the direction of the shark head of the shark model is taken as the navigation direction. The head pointing direction of the shark model may represent a right walk, a left walk, an up walk, a down walk, a forward walk, or a backward walk in the navigation direction.
In some embodiments of the present application, after the preset route model is imported, parameters of a preset route in the preset route model may be set according to a user requirement, so as to set the parameters of the preset route as target parameters, and after the electronic device is calibrated, preset path information, a direction identifier, a second calibration identifier, and a device identifier of the preset route with the target parameters are displayed. The target parameters include the total length of the route, the length of each sub-route, the angle at which each sub-route turns, the origin coordinate information and the destination coordinate information of the route.
For example, as shown in fig. 10 (1001), in the case where the route model of the preset route selected by the user is an M-type route model, the M-type route recorded by the M-type route model is a route in the depth direction, the guide information a6 is displayed on the display screen, and the parameter of the M-type route is set as the target parameter according to the display guide information a 6. The M-type route model comprises a first sub-route, a second sub-route, a third sub-route and a fourth sub-route, wherein one end of the first sub-route is a starting point of a departure stroke, and one end of the fourth sub-route is a finishing point of the departure stroke. The guide information a6 is, for example, "please set the total length of the M-type path". The lengths of the first sub-route and the fourth sub-route may be set to be the same, the lengths of the second sub-route and the third sub-route are the same, and the length of the first sub-route is a preset multiple of the length of the second sub-route, and an angle at which the first sub-route turns to the second sub-route, an angle at which the second sub-route turns to the third sub-route, and an angle at which the third sub-route turns to the fourth sub-route may be set, so that a preset route having a target parameter is obtained.
As shown in fig. 10 (1002) and 10 (1003), after setting the parameter of the preset route as the target parameter, the electronic device needs to be calibrated, and after the electronic device is calibrated, the guide information b6 is generated on the display screen, for example, "after clicking the power key to start recording, the generation of the path" is started, and the user clicks the power key to display the preset route L6 with the target parameter, the direction identifier f6, the device identifier c6 and the second calibration identifier d6 on the display screen, so as to guide the user to move according to the preset path information.
Step 203, updating the display state of the direction identifier based on the travel direction corresponding to the preset path information and the current travel direction of the electronic device.
In the step, the direction identifier indicates the navigation direction according to the preset path information, and when the user is navigated, the display state of the direction identifier is updated based on the travel direction corresponding to the preset path information and the current travel direction of the electronic device, and the display state of the direction identifier is the indication direction of the direction identifier.
For example, as shown in fig. 9 (903), the direction identifier f5 indicates the navigation direction of the electronic device, the navigation direction indicated by the direction identifier f5 may be obtained by making a difference between the current location information of the electronic device and the location information of the target route model, and when the direction of the user is incorrect or correct, a prompt message is generated to display the prompt message on the display screen, and the direction of the direction identifier f5 is changed to indicate the navigation direction, and when the traveling direction of the user is different from the direction corresponding to the preset path information, the prompt message is, for example, "adjust direction, go to the upper left", and when the traveling direction of the user is the same as the direction corresponding to the preset path information, the prompt message is, for example, "direction is correct, please go straight", etc.
Step 204, updating the display state of the device identifier based on the current gesture of the electronic device and the calibration gesture associated with the preset path information.
In this step, the display state of the device identifier may be updated by comparing the current gesture of the electronic device with the calibration gesture associated with the preset path information, so as to navigate the user. The display state of the device identifier specifically characterizes the relative positional relationship between the display parameters of the device identifier and the display parameters of the second calibration identifier. And by adjusting the display state of the equipment identifier, and under the condition that the display parameters of the equipment identifier are matched with the display parameters of the second calibration identifier, the electronic equipment is shown to shoot according to the gesture of the electronic equipment when the electronic equipment is recorded according to the preset route model. Wherein, step 204 and step 203 are implemented without timing difference, and can be performed simultaneously; step 204 may also be performed first, and then step 203 may be performed; step 203 may also be performed first, followed by step 204.
For example, as shown in fig. 11, when the matching state of the display parameter of the device identifier a5 and the display parameter of the second calibration identifier b5 is as shown in fig. 11 (1101) at the time of navigation, the presentation information c5 appears as "the mobile phone needs to rotate rightward". When the matching state of the display parameter of the device identifier a5 and the display parameter of the second calibration identifier b5 is as shown in fig. 11 (1102), the occurrence prompt information c5 is "the mobile phone needs to rotate leftwards". When the matching state of the display parameter of the device identifier a5 and the display parameter of the second calibration identifier b5 is as shown in fig. 11 (1103), the occurrence prompt information c5 is "the mobile phone needs to rotate upward". When the matching state of the display parameter of the device identifier a5 and the display parameter of the second calibration identifier b5 is as shown in fig. 11 (1104), the occurrence prompt information c5 is "the mobile phone needs to rotate downward".
