[0047] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] The embodiment provided in the present application is an embodiment of a hand-drawing system for a temporary navigation path.

[0049] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0050] The embodiment of the present application provides a hand-drawing system for a temporary navigation path, including: a navigation terminal 11 and a server 12 .

[0051] The navigation terminal 11 is a terminal capable of touch screen operation, which can be a personal mobile terminal (including but not limited to smart phones, desktop computers, tablet computers, laptops, digital assistants, smart wearable devices, etc.), or a vehicle-mounted mobile terminal, but the present application is not limited thereto.

[0052] The navigation terminal 11 is configured to: after determining the starting position of the hand-drawn navigation and the exit position of the parking lot, map the detected touch screen information to the displayed electronic map of the parking lot to generate a hand-drawn navigation track.

[0053] Wherein, the hand-drawn navigation track starts from the starting point position.

[0054] The electronic parking lot map can provide the map information needed for hand-drawn navigation.

[0055] The starting position is determined by the positioning module in the navigation terminal 11. In order to ensure that the position located by the navigation terminal 11 can be used as the starting position of the vehicle navigation track, the navigation terminal 11 needs to be positioned in the vehicle to ensure that the position located by the navigation terminal 11 is consistent with the vehicle position.

[0056] The electronic map of the parking lot may be stored in the navigation terminal 11 or may be temporarily downloaded before hand-drawn navigation, but the present application is not limited thereto.

[0057] The parking lot exit location is provided by the parking lot electronic map. Before hand-drawn navigation, multiple parking lot exit locations can be obtained by querying the parking lot electronic map.

[0058] Touch screen information refers to information generated by touching the screen of the navigation terminal 11. In order to realize hand-drawn navigation tracks on the navigation terminal 11, the embodiment of the present application converts the detected touch screen information into hand-drawn navigation tracks in the parking lot electronic map.

[0059] In some specific embodiments, the navigation terminal 11 is configured to map the detected touch screen information to the displayed electronic map of the parking lot after determining the starting point position and the exit position of the hand-drawn navigation, and generate a hand-drawn navigation trajectory, including: determining the starting point position and the exit position of the parking lot of the hand-drawn navigation; generating hand-drawn navigation request information based on the starting point position and the exit position of the parking lot; transmitting the hand-drawn navigation request information to the server 12; in response to receiving the permission information fed back by the server 12 based on the hand-drawn navigation request information, generating a hand-drawn interactive interface based on the electronic map of the parking lot; detecting the touch screen information based on the hand-drawn interactive interface, and mapping the touch screen information to the displayed electronic map of the parking lot, to generate a hand-drawn navigation trajectory.

[0060] The server 12 is a device that provides hand-drawn navigation services. The server 12 is wirelessly connected to the navigation terminal 11 to provide services for the navigation terminal 11 to generate hand-drawn navigation tracks.

[0061] In this specific embodiment, the navigation terminal 11 first generates hand-drawn navigation request information based on the starting point location and the parking lot exit location, and requests the server 12 to provide hand-drawn navigation service. When receiving the permission information fed back by the server 12, the navigation terminal 11 generates a hand-drawn interactive interface based on the parking lot electronic map, and the hand-drawn interactive interface includes the parking lot electronic map. The touch screen information detected in the hand-drawn interactive interface can generate a hand-drawn navigation track.

[0062] The server 12 is a device that provides hand-drawn navigation services. The server 12 is wirelessly connected to the navigation terminal 11 to provide services for the navigation terminal 11 to generate hand-drawn navigation tracks.

[0063] The server 12 is configured to: determine the entrance position and each exit position of the next target intersection in the electronic map of the parking lot based on the trajectory trend of the hand-drawn navigation trajectory, obtain the shortest path distance value from the corresponding exit position of the target intersection to the exit position of the parking lot based on the each exit position of the target intersection and the exit position of the parking lot, transmit the shortest path distance value of each exit position of the target intersection and the entrance position of the target intersection to the navigation terminal 11, and trigger the navigation terminal 11 to display the shortest path distance value of each exit position before the hand-drawn navigation trajectory reaches the entrance position of the target intersection.

[0064] When the hand-drawn navigation track is drawn between two intersections, it can be determined that the track trend of the hand-drawn navigation track is the next intersection in the moving direction of the hand-drawn navigation track.

[0065] With respect to the hand-drawn navigation track, each intersection includes an entrance and multiple exits. The entrance position is the first position passed by the hand-drawn navigation track, and the exit is the position to be passed by the hand-drawn navigation track. Since there are multiple exits, there are also multiple possible passing positions to be determined. For this reason, in an embodiment of the present application, the navigation terminal 11 is provided with the shortest path distance value from each exit to the parking lot exit position for the user to refer to and select when drawing the hand-drawn navigation track. For this reason, when the navigation terminal 11 draws the hand-drawn navigation track entering the passage between two intersections, before entering the entrance of the next intersection, the shortest path distance value of each exit position of the next intersection is always displayed, so that the user can quickly select the exit position of the hand-drawn navigation track at the next intersection through the shortest path distance value of each exit position of the next intersection, thereby improving the efficiency of hand-drawing.

[0066] In some specific embodiments, the navigation terminal 11 is configured to, in response to receiving permission information fed back by the server 12 based on the hand-drawn navigation request information, display a hand-drawn interactive interface generated based on the parking lot electronic map, and also includes: generating a hand-drawn tool icon at the starting point of the parking lot electronic map on the hand-drawn interactive interface.

[0067] Since the display area of ​​the navigation terminal 11 is too small, the area for displaying the hand-drawn interactive interface is limited. In order to avoid confusion in the hand-drawn navigation track, the track width of the hand-drawn navigation track is limited. Too thin a track width can easily cause an unrealistic feeling when drawing. For this reason, this specific embodiment provides a hand-drawn tool icon (such as a hand icon or a brush icon) to increase the interactive area between the hand-drawn navigation track and the touch screen information, so that the user can use the hand-drawn tool icon as a gripper to draw the hand-drawn navigation track. This improves the feeling of human-computer interaction.

[0068] In some specific embodiments, the navigation terminal 11 is configured to map the touch screen information to the displayed electronic map of the parking lot and generate a hand-drawn navigation trajectory, including: when the touch screen information is mapped to the hand-drawn tool icon, activating the hand-drawn tool icon to move with the touch screen information; and generating the hand-drawn navigation trajectory in the electronic map of the parking lot based on the movement trajectory of the hand-drawn tool icon activated by the touch screen information.

[0069] In this specific embodiment, when the touch screen information is mapped to the hand-drawing tool icon, the hand-drawing tool icon is activated so that the hand-drawing tool icon can move along with the touch screen information, so that the user can feel the feeling of using a brush to draw a hand-drawn navigation track, thereby improving the user experience.

[0070] In some specific embodiments, the navigation terminal 11 is configured to generate the hand-drawn navigation trajectory in the parking lot electronic map based on the moving trajectory of the hand-drawn tool icon activated by the touch screen information, including: when the touch screen information moves from a static state to a sliding state, calculating the sliding speed value within a preset sliding time; and determining the drawing speed value of the hand-drawn tool icon in the parking lot electronic map based on the sliding speed value.

[0071] For example, the hand-drawing tool icon stays at the starting position of the vehicle, and after the hand-drawing tool icon is activated, the screen is quickly swiped in the hand-drawing interactive interface; or, when the touch screen information is in a static state and the drawing speed value is greater than zero, when the touch screen information moves from a static state to a swiping state again, the swiping speed value within the preset swiping time is recalculated, and then the new drawing speed value of the hand-drawing tool icon in the electronic map of the parking lot is determined.

[0072] In this specific embodiment, the user can change the drawing speed value as needed, thereby improving the user experience.

[0073] In some specific embodiments, the navigation terminal 11 is further configured to: when the touch screen information changes from the sliding state to the static state, determine that the hand-drawn tool icon still draws the hand-drawn navigation trajectory in the parking lot electronic map based on the drawing speed value.

[0074] Since the area of ​​the hand-drawn interactive interface is limited, the distance of a screen swipe is limited. In order to ensure that the hand-drawn navigation track can be drawn quickly, this specific embodiment provides a static drawing method. That is, after a screen swipe, the touch screen information is in a static state, and the hand-drawn navigation track is still drawn according to the drawing speed value obtained when the screen is swiped. Not only does it break through the drawing restrictions of the hand-drawn interactive interface, but it also still ensures the drawing speed, thereby improving the user experience.

[0075] In some specific embodiments, the navigation terminal 11 is further configured to: when the touch screen information changes from the sliding state to the static state, when the hand-drawn navigation trajectory is still drawn to the entrance position of the target intersection according to the drawing speed value, suspend drawing of the hand-drawn navigation trajectory.

[0076] That is, when the touch screen information is static and the hand-drawn navigation track is still drawn according to the drawing speed value, when the drawing reaches the entrance position of the target intersection, the drawing of the hand-drawn navigation track is suspended so that the user can make a judgment and choose which exit to continue drawing. When the user determines the exit, the drawing can be resumed by swiping the screen. This improves the user experience.

[0077] In the embodiment of the present application, the service end 12 provides the navigation terminal 11 with a quick service for drawing a hand-drawn navigation track, and provides the shortest path distance value of each exit position of the next target intersection under the track trend of the hand-drawn navigation track. The navigation terminal 11 maps the touch screen information to the displayed parking lot electronic map through human-computer interaction, and draws the hand-drawn navigation track with reference to the shortest path distance value of each exit position of each target intersection, thereby improving the efficiency of hand-drawing. By drawing the hand-drawn navigation track, users can quickly and conveniently draw navigation maps according to actual needs and personal preferences, which improves the flexibility of navigation and improves the user experience.

[0078] The present application also provides a method embodiment that is based on the above embodiment. The explanation based on the same name meaning is the same as that of the above embodiment, and has the same technical effect as the above embodiment, which will not be repeated here.

[0084] In the embodiment of the present application, the service end 12 provides the navigation terminal 11 with a quick service for drawing a hand-drawn navigation track, and provides the shortest path distance value of each exit position of the next target intersection under the track trend of the hand-drawn navigation track. The navigation terminal 11 maps the touch screen information to the displayed parking lot electronic map through human-computer interaction, and draws the hand-drawn navigation track with reference to the shortest path distance value of each exit position of each target intersection, thereby improving the efficiency of hand-drawing. By drawing the hand-drawn navigation track, users can quickly and conveniently draw navigation maps according to actual needs and personal preferences, which improves the flexibility of navigation and improves the user experience.
