The invention will now be described in detail with reference to exemplary embodiments, some examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same reference numerals in different drawings represent the same or similar elements, unless otherwise indicated. The schemes described in the following exemplary embodiments do not represent all schemes of the present invention. Rather, these are merely examples of systems and methods of various aspects of the present invention that are set forth in the following claims.
The navigation system according to the embodiment of the invention may be mounted on or applied to a vehicle. The vehicle may be an internal combustion engine vehicle using an internal combustion engine as a driving source, an electric vehicle or a fuel cell vehicle using an electric motor as a driving source, a hybrid vehicle using both of them as driving sources, or a vehicle having another driving source. It should be appreciated that the navigation system according to the present invention may be applied in other scenarios besides being mounted on or applied to a vehicle. For example, the navigation system may be included in a cell phone, personal Digital Assistant (PDA), wearable device, computer, tablet computer, or the like.
FIG. 1 is a schematic diagram of a navigation system according to an embodiment of the invention. As shown in fig. 1, the navigation system 10 may include a navigation device 100 and a display device 200. The navigation device 100 may be connected and communicate with the display device 200 by wire or wirelessly. As shown in fig. 1, the navigation device 100 may include a map display unit 110, a trajectory acquisition unit 120, a route point identification unit 130, a point of interest recommendation unit 140, and a route planning unit 150. In an exemplary embodiment, the display device 200 may be a touch display device that may both display information to a user and allow the user to input information thereon via a finger, a stylus, or the like. The display device 200 may be implemented using LCD (liquid crystal display) technology, LPD (light emitting diode polymer display) technology, OLED (organic LED) or OEL (organic electroluminescence) technology, or the like.
The map display unit 110 may provide a map for display on the display device 200. The map display unit 110 may acquire map data from a local or remote location. In some embodiments, the navigation device 100 may include or be connected to a map database, and the map display unit 110 may acquire map data from the map database. The map display unit 110 may transmit a map to be displayed to the display device 200, so that the display device 200 may display the map to the user. In some embodiments, the map display unit 110 may set the current location of the user as the center of the displayed map. In some embodiments, when the display device 200 displays a map to a user, the user may adjust the center, scale, direction, etc. of the displayed map by performing zoom, slide, drag, rotate, etc. actions on the display device 200.
The trajectory acquisition unit 120 may receive an initial trajectory (first trajectory) drawn by a user on the display device 200 on which the map is displayed. The initial trajectory is a navigation-assisted trajectory, indicating that the user desires a navigation path to extend along the initial trajectory. The user may draw a continuous line, a discrete point, etc. on the display device 200 using a finger, a stylus, etc. to form a track. Discrete lines and points represent the user drawing the track in a jumping manner. The trajectory acquisition unit 120 may receive the trajectory drawn by the user from the display device 200. In an exemplary embodiment, the display apparatus 200 may display a user-drawn trajectory on a map. Thus, the user can intuitively observe the track drawn by the user.
Fig. 2 is a schematic diagram of a navigation system showing a map according to an embodiment of the present invention. As shown in fig. 2, the navigation system according to the embodiment of the present invention displays a map on which a user draws a trajectory.
According to some embodiments of the present invention, the trajectory acquisition unit 120 may also receive a user confirmation of the drawn trajectory, for example from the display device 200. After the user draws a track on the display device 200, the user can confirm the drawn track by touching a corresponding button on the display device 200. Thereby, the trajectory acquisition unit 120 will acquire the trajectory confirmed by the user from the display device 200. In some embodiments, the user may supplement, modify, delete, etc. the track he draws before confirmation.
According to an embodiment of the present invention, the trajectory acquisition unit 120 may also convert the image coordinates of the pixels of the initial trajectory into map coordinates on a map. It should be appreciated that the trajectory drawn by the user is a collection of a series of pixels, each having corresponding image coordinates. In order to correlate the drawn trajectory with the displayed map, it is necessary to convert the image coordinates of the pixels in the trajectory into map coordinates. Accordingly, the trajectory acquisition unit 120 may map the trajectory received from the display device 200 into a map coordinate system to obtain map coordinates of all pixel points in the drawn trajectory.
According to some embodiments of the present invention, the trajectory acquisition unit 120 may also identify a start pixel and an end pixel of the trajectory drawn by the user. In some embodiments, the trajectory acquisition unit 120 may also receive a drawing order of the pixels in the trajectory, for example from the display device 200. In some embodiments, the track acquisition unit 120 may identify a start pixel point and an end pixel point of the track according to the drawing order of the pixel points in the track. In some embodiments, the track acquisition unit 120 may further identify a start pixel point and an end pixel point of the track according to a selection of a user. For example, the user may select one pixel point to be drawn as a start pixel point and another pixel point as a stop pixel point on the display device 200.
The waypoint identification unit 130 may determine the navigation start point according to the drawn trajectory. As described below, the path planning unit 150 will plan a navigation path starting from a navigation start point. According to some embodiments of the present invention, the path point identifying unit 130 may determine the navigation start point according to the start pixel point of the drawn initial trajectory. In some embodiments, the path point identifying unit 130 may set the map coordinates of the starting pixel point as the navigation start point.
According to some embodiments of the present invention, the path point identifying unit 130 may also determine the navigation start point according to a pixel point closest to the map coordinates of the current location of the user. In some embodiments, the path point identifying unit 130 may set map coordinates of a pixel point closest to the current position of the user in the initial trajectory as the navigation start point. In some embodiments, the path point identifying unit 130 may acquire map coordinates of the current location of the user and determine whether at least one pixel point of the initial trajectory exists within a predetermined range around the current location of the user. If the route point identification unit 130 determines that at least one pixel point of the initial trajectory exists in a predetermined range around the current position of the user, map coordinates of the pixel point nearest to the current position of the user are set as the navigation start point. In some embodiments, the waypoint identification unit 130 may also determine the navigation origin based on the user's selection. For example, the user may select one pixel point in the initial trajectory on the display device 200, whereby the route point identifying unit 130 may set the map coordinates of the selected pixel point as the navigation start point.
The point of interest recommending unit 140 may search for a plurality of first points of interest within a predetermined range around the ending pixel point of the initial trajectory. In an exemplary embodiment, the categories of points of interest may include dining, shopping, accommodation, entertainment, finance, life services, real estate, travel, and the like. In some embodiments, the point of interest recommendation unit 140 may search for the first point of interest according to the point of interest category selected by the user, for example, the point of interest category selected by the display device 200. In some embodiments, the point of interest recommendation unit 140 may also search for the first point of interest according to the user's point of interest preference. The point of interest recommendation unit 140 may obtain the user's point of interest preferences locally or remotely. The user's point of interest preferences may be set by the user or generated based on the user's historical data (e.g., travel data, search data, etc.).
The point of interest recommending unit 140 may provide the first point of interest searched to the user. In an exemplary embodiment, the point of interest recommending unit 140 may transmit the searched first point of interest to the display device 200 to display a plurality of first points of interest to the user. In some embodiments, the point of interest recommendation unit 140 may rank the first points of interest searched according to the distance to the termination pixel point; and providing the first points of interest to the user in a near-to-far order. In the drawing process, there may be a deviation between the end pixel point of the trajectory drawn by the user and its intended destination due to factors such as resolution, operation accuracy, and the like. In this case, searching for and recommending points of interest around the drawn track to the user may provide more accurate navigation.
The path planning unit 150 may receive the first point of interest selected by the user as a navigation end point. In an exemplary embodiment, the path planning unit 150 may receive a user selection of the first point of interest from the display device 200. For example, while a plurality of first points of interest are displayed on the display device 200, the user may select by touching the corresponding points of interest on the display device 200. In some embodiments, if the selection of the first interest point by the user is not received within the predetermined time, the path planning unit 150 may take the interest point closest to the termination pixel point as the selected first interest point, or the map coordinates corresponding to the termination pixel point in the map as the selected first interest point.
The path planning unit 150 may plan a navigation path from the navigation start point to the selected first point of interest according to the drawn trajectory and the selected first point of interest. In an exemplary embodiment, the path planning unit 150 may plan a plurality of different navigation paths from the navigation start point to the selected first point of interest. In some embodiments, the path planning unit 150 may estimate travel times according to the respective navigation paths, respectively, and output the estimated travel times and/or travel distances.
In an exemplary embodiment, the path planning unit 150 may transmit the planned one or more navigation paths to the display device 200 to display the navigation paths to the user. In some embodiments, the display device 200 may also receive and display the estimated travel time and/or travel distance from the path planning unit 150. The user may select, confirm or modify the navigation path on the display device 200, as described below.
According to some embodiments of the present invention, the path point identifying unit 130 may also identify turning pixels in the drawn trajectory. Turning pixels in the mapped trajectory may correspond to turning points in the map. In some embodiments, the path point identifying unit 130 may identify turning pixel points according to the curvature of the drawn trajectory, and obtain map coordinates of the turning pixel points from the trajectory acquiring unit 120. In some embodiments, the path point identifying unit 130 may acquire map coordinates of each pixel point in the drawn trajectory from the trajectory acquiring unit 120, and identify turning pixel points according to deflection angles between the map coordinates of the pixel points.
According to some embodiments of the present invention, the point of interest recommending unit 140 may search for a plurality of second points of interest within a predetermined range around the turning pixel point for each turning pixel point, and provide the second points of interest to the user. In some embodiments, the point of interest recommendation unit 140 may search for the second point of interest according to the user selected point of interest category or the user's point of interest preference, as described above. In an exemplary embodiment, the point of interest recommending unit 140 may transmit the searched second point of interest to the display device 200 to display the plurality of second points of interest to the user.
In an exemplary embodiment, the second interest points searched around the turning pixels may include roads of different grades and roads of different orientations, in addition to the above-mentioned. For example, when a planar intersection exists at a turning pixel point, the point of interest recommending unit 140 may provide the user with different roads at the intersection for selection by the user. For example, when an overpass exists at a turning pixel point, the point of interest recommending unit 140 may provide roads of different layers to the user for selection by the user. For example, the point of interest recommending unit 140 may provide the user with different level roads (e.g., main road, auxiliary road, branch road, etc.) and/or road entrances and exits near the turning pixels, so that the path planning unit 150 may determine whether the planned navigation path needs to enter or leave, for example, a specific road according to the user's selection.
According to some embodiments of the present invention, the path planning unit 150 may receive the second point of interest selected by the user. In an exemplary embodiment, the path planning unit 150 may receive a user selection of the second point of interest from the display device 200. In some embodiments, if the user's selection of the second interest point is not received within a predetermined time, the path planning unit 150 may take the second interest point closest to the turning pixel point as the selected second interest point, or take the map coordinates corresponding to the turning pixel point in the map as the selected second interest point.
According to some embodiments of the present invention, the path planning unit 150 may further plan a navigation path according to the drawn trajectory, the selected first interest point and the second interest point, wherein the navigation path reaches the selected first interest point from the navigation start point through the selected second interest point. The path planning unit 150 plans other aspects of the navigation path as described above.
According to some embodiments of the present invention, the path point identifying unit 130 may further output a hint signal when it is determined that there is no pixel point of the initial track within a predetermined range around the current position of the user. According to an embodiment of the present invention, the hint signal may include: prompting that the current position of the user is not near the drawn initial track; and prompting the user to redraw the track. The waypoint identification unit 130 may transmit a prompt signal to the display device 200 so that the display device 200 may prompt the user in a graphic, text, voice, or the like manner. After the waypoint identification unit 130 outputs the hint signal, the trajectory acquisition unit 120 may receive the trajectory redrawn by the user. The redrawn track may be completely replaced, partially replaced, or added to the original track.
According to some embodiments of the present invention, when the display apparatus 200 displays one or more planned navigation paths, the display apparatus 200 may instruct the user to confirm one navigation path, select one navigation path from a plurality of navigation paths, or reject all navigation paths. In some embodiments, the display device 200 may also instruct the user to make corrections to a certain planned navigation path, as described below.
According to some embodiments of the present invention, when the user refuses the navigation path on the display device 200, the navigation device 100 may re-plan the navigation path or instruct the user to modify the navigation path. The user rejection of the navigation path indicates that the user is dissatisfied with the planned navigation path.
