Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Various specific embodiments of a method for generating a guidance prompt identifier according to an embodiment of the present invention are described in detail below.
The embodiment of the invention provides a method for generating a guidance prompt identifier, which can be applied to respective navigation equipment, a vehicle-mounted navigator and a mobile terminal with a navigation function, and comprises the steps of S101-S104, as shown in FIG. 1.
S101, receiving an intersection guide prompt instruction, and determining the information of an entrance and an exit of an intersection;
s102, dividing an angle area corresponding to a preset guide direction;
s103, determining the relation between the out-of-route information and the angle area, and obtaining a preset guiding direction corresponding to the out-of-route;
s104 synthesizes guidance prompt marks including an entry route and an exit route.
In the guiding process, the position of the vehicle and the distance to the next intersection need to be continuously determined, so as to determine the display and elimination timing of the intersection prompt guide picture, generally, when the vehicle reaches a certain distance from the intersection ahead in the driving direction, an instruction for displaying the intersection guide prompt is automatically sent out, and in step S101, when the instruction for displaying the intersection guide prompt is received, the guide prompt of the road direction needs to be displayed when the instruction for displaying the intersection guide prompt is received, so as to give a user a prompt about the driving direction of the next intersection.
In one embodiment, in step S102, a guiding direction with a certain angle is preset as needed, and the corresponding angle area is divided according to the guiding direction to divide the intersection angle area, where the preset guiding direction may be preset 8 directions, 10 directions, 12 directions, 18 directions, 24 directions, 36 directions, and the like, each of which is a preset picture, or may display drawing data of the guiding direction, and the preset guiding direction is, for example, twelve o' clock direction of a clock, the preset guiding direction is 12 directions, which are 0 (360) degree, 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, 180 degrees, 210 degrees, 240 degrees, 270 degrees, 300 degrees, and 330 degrees, and the intersection is divided according to the above directions into 12 areas, each area corresponds to a certain angle interval, and each area may respectively correspond to a central line, and twelve areas are evenly allocated, as shown in fig. 2, or an uneven allocation method may be adopted, and only one guiding direction needs to be uniquely allocated for each angle area.
In one embodiment, in step S103, it is necessary to determine the relationship between the obtained exit route information and the divided angle regions, so as to obtain the guiding directions corresponding to all or part of exit routes at the intersection; the entrance, the guide exit and the background exit of the intersection form all related roads of the intersection, wherein the angle relationship between the entrance, the guide exit and the background exit is determined, and the relationship between the exit and the preset guide direction is determined, wherein the direction of the entrance can be matched with the preset guide direction, the entrance can be matched to the most similar angle area according to the actual road, the entrance can be forcibly converted into the upward straight direction, and when the entrance direction and the position of the angle area are determined, the angle areas corresponding to other exits can be determined.
In one embodiment, in step S104, the entry of the intersection and the guiding direction corresponding to each departure are obtained, and a guiding prompt identifier including the entry and the departure is synthesized, where the guiding prompt identifier may be a guiding prompt picture synthesized by combining a plurality of single-direction pictures into one guiding prompt picture with an intuitive intersection prompt function, or may be another presentation form with a guiding prompt function obtained by drawing according to corresponding data, such as a vector diagram.
By adopting the method, not only the entering way and the guiding leaving way can be displayed, but also other background leaving ways can be displayed under the condition of prompting the crossing guiding route, wherein the entering way and the guiding leaving way can be highlighted, and can be distinguished from other background leaving ways by adopting other modes, so that more visual direction display is brought to a user, the distribution condition of the road condition of the crossing is more clearly displayed, clear direction guide is brought to the user, and the condition of walking by mistake caused by wrong distinguishing of the direction of the crossing is reduced.
In one embodiment, in step S103, the method includes:
s201, determining a reference direction according to the direction of an entry road;
s202, judging whether the relative angles of the outgoing paths are distributed in different angle areas, if so, turning to S203, and if not, turning to S204;
s203, extracting guide marks corresponding to different angle areas of the relative angle distribution of the outgoing path;
s204, extracting a guide identifier corresponding to the angle area where the guide escape way is located.
The reference direction can be right above or other standard directions; all the drop-out ways correspond to the preset angle areas, the relation between the distribution of the drop-out ways of the current intersection and the distribution of the preset angle areas is compared, whether each drop-out way uniquely corresponds to one angle area or not is confirmed, and when each drop-out way uniquely corresponds to one angle area, the corresponding guide directions of all the drop-out ways of the intersection can be displayed; when one angle area corresponds to a plurality of exit ways, the direction of the entrance way and the direction of the guide exit way can be only displayed for guiding, or the angle area of the guide exit way can be obtained first, and the guide directions of two adjacent left and/or right exit ways within a certain angle range are forcibly converted into the guide directions corresponding to the adjacent angle areas.
In one embodiment, in step S103, the method includes:
on the basis of the steps, when the same angle area comprises a plurality of outgoing paths, the number of the outgoing paths is further judged; when the outgoing path is a two-way path or a three-way path, converting the relative angle of the outgoing path into an adjacent angle area according to a preset algorithm; and extracting the guide identification corresponding to the angle area after the relative angle conversion of the outgoing path.
In real life, most angles of actual road conditions are not accurate, and if the angles are displayed strictly according to the angles, a plurality of intersections are very close to a preset angle model but cannot be displayed, so that the non-conforming angle directions need to be finely adjusted through a special algorithm to be in accordance with a twelve o 'clock mode, and simple guides of most intersections can be displayed in the preset angle mode (such as the twelve o' clock mode).
In one embodiment, the determined exit route is a bifurcate route, and the two exit routes are converted by using the preset algorithm if the same angle region includes two exit routes.
The preset algorithm is a fine adjustment algorithm, fine adjustment precisions A and B are preset, the fine adjustment precision is a preset angle range, and the fine adjustment algorithm is characterized in that two separation paths are respectively arranged to different directions according to the difference of angles, so that the two separation paths conform to a twelve o 'clock model and are displayed according to the twelve o' clock model. For example, the setting direction is twelve o 'clock direction, two drop paths are present in the twelve o' clock angle area, a drop path a [0], a [1] is identified, and preset fine adjustment precisions A and B are obtained, wherein A is used for adjusting the angle of the smaller drop path, B is used for adjusting the angle of the larger drop path, A can be +/-2 degrees, +/-3 degrees, etc., B can be +/-10, +/-12, etc., when the angle of the drop path a [0] is in the A range and the angle of the drop path a [1] is in the positive range of B, a [1] is adjusted to one o 'clock direction, if the angle of the drop path a [1] is in the negative range of B, a [1] is adjusted to eleven o' clock direction.
In one embodiment, the determined exit is a three-way exit, and the three exit are included in the same angle area, and are converted into two-way exit conditions according to different conditions, and then the guidance directions of the three-way exit are converted by adopting the preset algorithm.
For the three-way road, the road condition which does not conform to the twelve o' clock model is divided into two cases: and the preset algorithm can respectively set the three escape routes to different directions according to the difference of angles, so that the three escape routes conform to the model of the standard direction and are displayed according to the preset direction.
And marking the outgoing paths a [0], a [1], a [2], and obtaining the preset fine adjustment precisions A and B of the corresponding angle areas, wherein A is used for adjusting the angle deviated from the smaller outgoing path, and B is used for adjusting the angle deviated from the larger outgoing path.
Take the preset direction as twelve o' clock direction as an example: the method for generating the guidance prompt identifier comprises the following steps:
and traversing each drop-out path and counting the angle area corresponding to each drop-out path.
Judging that the angles of the two outgoing paths are the same, if so, not processing; if not, the next step of judgment is carried out
If the angle of two outgoing paths is very close to the straight line, the processing is not carried out, because the deviation of one angle is possibly large due to the path cutting, and the two outgoing paths are actually closer to the straight line.
If the angle of the left fork and the right fork deviates from the straight direction obviously, the central fork is close to the straight direction, and the angle value is directly and forcibly changed to meet the twelve o' clock direction; then, it is assumed that a [0], a [1] are in the same direction, and the processing flow is as a fork, except that if a [2] is in the adjacent clock direction, and one of a [0], a [1] needs to be adjusted to the clock direction of a [2], then the direction of a [2] needs to be adjusted again.
For the situation that three drops fall in the same clock direction at the same time, if the center fork is 0 degree, the left fork and the right fork are forced to conform to the clock model as long as the deviation is more than 1 degree; if the left bifurcation is 0 degree, the center bifurcation and the right bifurcation are forced to conform to the clock point model as long as the center bifurcation and the right bifurcation have little point deviation other than 0 degree; if the right branch is 0 degrees, the center and left branches are forced to conform to the clockwork model as long as there is a slight deviation other than 0 degrees. The general principle is to set the one closest to the hour direction and then adjust the other two hour directions to conform to the twelve hour model.
In one embodiment, the step S104 synthesizes guidance prompt identifiers including an entry route and an exit route, specifically:
at least 2 guiding prompt identifiers, namely a driving guiding direction and a background guiding direction, are preset in each guiding direction, the attributes of an entrance way, a guiding exit way and a background exit way of the intersection are determined, and the driving guiding direction or the background guiding direction corresponding to the guiding direction is determined and obtained according to the attributes; acquiring a driving guide direction corresponding to an entrance road and a guide escape road and a background guide direction corresponding to a non-guide escape road; and combining the driving guide direction and the background guide direction to generate a guide prompt identifier, as shown in fig. 4.
