For above-mentioned purpose of the present invention, feature and advantage can more be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization under the situation of intension of the present invention.Therefore the present invention is not subjected to the restriction of following public embodiment.
The schematic flow sheet of the embodiment of a kind of air navigation aid of the present invention as shown in Figure 1.With reference to figure 1, described air navigation aid comprises:
Step S1: electronic chart draw navigation object from the departure place to the benchmark route of destination;
Step S2: the current location information of determining described navigation object;
Step S3: determine that based on the current location information of described navigation object described navigation object is with respect to the angular deflection parameter of described benchmark route;
Step S4: when described angular deflection parameter during greater than angle threshold, writing time parameter, wherein, described time parameter identifies described angular deflection parameter greater than time that angle threshold continued;
Step S5: when described time parameter greater than very first time threshold value and less than second time threshold, send indication information to the user, wherein said indication information is used to indicate on the direction that described navigation object revert to described benchmark route;
Step S6: when described time parameter greater than described second time threshold, redefine navigation way based on current location information and the described destination of described navigation object.
Particularly, in the present embodiment, described navigation object is automobile, and the guider that the embodiment of the invention provides has been installed on this automobile, provides navigation way for the user drives a car.In actual applications, after the user opens described guider, described guider will obtain the position at the current place of automobile (being described navigation object) automatically by built-in gps receiver, and this position namely can be used as the departure place usually.Then, the user imports the destination at the display of guider, and wherein said destination can be concrete road name and the road trade mark (for example No. a tunnel 211, crossdrift), also can be specified place (for example Four Seasons Hotel).
Need to prove that in the present embodiment, described guider has calculated a bar navigation route according to above-mentioned definite departure place and destination.Further, guider will be drawn a benchmark route according to departure place and destination on electronic chart, it is the straight-line segment of two-end-point with departure place and destination that this benchmark route is one, identified the direction from the starting point to the destination, just described benchmark route is indicated the direction (being step S1) of described navigation way.As can be seen, the benchmark route here is not the navigation way from described departure place to the destination that guider calculates, and what in fact described benchmark route was represented is the direction of navigation, namely arrives the direction of destination from the departure place.In actual applications, the colouring discrimination of the described benchmark route that shows on the guider display is in navigation way, so that this benchmark route of user discrimination.
Then, measure the satellite of known location by the built-in gps receiver of guider to the distance between the described gps receiver (being navigation object), and then just can determine the particular location of described navigation object in conjunction with the data of a plurality of satellites, then the display by described guider is presented at (being step S2) on the electronic chart with the current location information of described navigation object.Wherein, the principle of work of described gps receiver is technology as well known to those skilled in the art, does not repeat them here.
Further, in the present embodiment, described current location information comprises the coordinate information of described navigation object on electronic chart.The current location that it will be appreciated by those skilled in the art that generally the described navigation object that gets access to by gps receiver represents that by gps coordinate described gps coordinate is to be based upon in the coordinate system of real world, is represented by longitude and two parameters of latitude.Guider need convert described gps coordinate to local Gauss plane coordinate, to realize the correct coupling of gps coordinate in electronic chart.The process that concrete gps coordinate converts local Gauss plane coordinate to is technology as well known to those skilled in the art, does not repeat them here.
Then, determine that based on the current location information of described navigation object described navigation object is with respect to the angular deflection parameter (being step S3) of described benchmark route.
This step comprises: at first, according to the current coordinate information on described electronic chart of described navigation object, determine the line of described navigation object and described departure place and the angle angle between the described benchmark route.
Particularly, with reference to figure 2, suppose that here the A point is the destination for departure place, B point; AB straight-line segment 00 is that benchmark route, the AB segment of curve 01 of described departure place to destination is the navigation way of described departure place A to destination B.The navigation object (not shown) is current by way of the C point from the A point, and namely described C point is the current location of described navigation object, can determine the coordinate information that described C is ordered on electronic chart.At this moment, described C point and the described departure place A line AC of ordering and the angle angle between the described benchmark route are α.Because each Points And lines section on electronic chart all has coordinate information, and utilizes the angle calculation function of guider, those skilled in the art can calculate this angle angle [alpha], and its computation process is not given unnecessary details at this.
Then, determine that based on described angle angle described navigation object is with respect to the angular deflection parameter of described benchmark route.In the present embodiment, preferably directly with the above-mentioned angle angle [alpha] that calculates as the angular deflection parameter of described navigation object with respect to described benchmark route, but in actual applications, be not limited to this.Because the coordinate information on the electronic chart error may occur in computation process, therefore also can determine described angular deflection parameter based on the angle angle [alpha] plus-minus error that calculates.
Correspondingly, in step S4, when described angular deflection parameter during greater than angle threshold, writing time parameter, wherein, described time parameter identifies described angular deflection parameter greater than time that angle threshold continued.
In the present embodiment, setting described angle threshold is the right angle, namely when the line AC of described navigation object current location (being the C point) and described departure place A and the angle angle [alpha] between the described benchmark route are spent greater than 90, determine that then current described navigation object has departed from the direction (direction of destination in other words) of described benchmark route, but this moment, described navigation object may be necessary temporarily to depart from the direction of described benchmark route, in practical situation, near navigation object may need to enter advanced road, for example highway, highway section such as overhead.Therefore, need further consider time factor, determine that the direction that described navigation object begins to depart from described benchmark route works the time that is continued.
Continuation is with reference to figure 2, and is current during by way of the C point at navigation object, and described angle angle [alpha] is greater than 90 degree, this moment the opening entry time parameter.Then, described navigation object continues to advance and arrives C ' point, and at this moment, the line AC ' that described C ' point and departure place A are ordered and the angle angle between the described benchmark route are α ', suppose described angle angle [alpha] ' also greater than 90 degree.As can be seen from Figure 2, when navigation object advances to from the C point the process of C ' point, greater than 90 degree, namely in parametric t during this period of time, described angular deflection parameter is all greater than angle threshold all the time for angle angle between the line of described navigation object and departure place A and the described benchmark route.Need to prove that the angle threshold that present embodiment sets (90 degree) only is reference value, in actual applications, also can set other angle value as described angle threshold.
Then, when described time parameter greater than very first time threshold value and less than second time threshold, send indication information to the user, wherein said indication information is used to indicate on the direction that described navigation object revert to described benchmark route (being step S5).
In the present embodiment, threshold value of the described very first time and second time threshold can be determined based on the length of described benchmark route.Usually, if the distance between departure place and the destination is more far away, namely the length of described benchmark route is more long, can determine that then the time of described very first time threshold value and second time threshold is more long.And if the close together between departure place and the destination, namely the length of described benchmark route is shorter, can determine that then the time of described very first time threshold value and second time threshold is shorter.In other embodiments, described very first time threshold value and second time threshold also can be determined based on the length of navigation way.Further, described very first time threshold value is less than described second time threshold,
The described time parameter t that obtains according to above-mentioned steps S4, if described time parameter t is greater than the very first time threshold value that sets and less than second time threshold, though think that described navigation object has departed from the direction of benchmark route, but side-play amount is also little, therefore guides the user that described navigation object is revert on the direction of benchmark route by send indication information to the user.Wherein, mode from indication information to the user that send can be directly described indication information to be presented on the display of guider, perhaps by the described indication information of player voice broadcast, but is not limited thereto.
In the present embodiment, described indication information can be turning information, as navigation object is left or bend to right to be returned on the direction of benchmark route as described in indicating; Can also be directional information, as navigation object westwards travel along the West Road, Nanjing etc. with on the direction that is returned to the benchmark route as described in indicating; Can also be information of place names perhaps, indicate Four Seasons Hotel etc. that described navigation object reaches 500 meters, the place ahead being returned to the direction of benchmark route, but described indication information be not limited thereto.Indication information can in time guide navigation object to come back on the direction of described benchmark route (as the AB straight-line segment 00 among Fig. 2), so just needn't recomputate navigation way, thereby reduce the calculated amount of guider.
Further, as described in step S6, when described time parameter greater than described second time threshold, redefine navigation way based on current location information and the described destination of described navigation object.
In the present embodiment, particularly, think that described navigation object has departed from described benchmark route far away this moment, in this case, may need to take a long time if will be again guide the user that described navigation object is revert on the direction of benchmark route again by indication information.
Therefore, in the present embodiment, when definite described time parameter t greater than described second time threshold, then redefine navigation way according to current coordinate information and the described destination coordinate information on described electronic chart on described electronic chart of described navigation object.In other words, be exactly guider will be that terminal point recomputates a bar navigation route with described destination (being original destination B) with the current location of described navigation object as starting point.Wherein, the described process that recomputates navigation way is technology as well known to those skilled in the art, does not repeat them here.
Need to prove, in actual applications, when described time parameter greater than very first time threshold value and less than second time threshold, guider will send indication information, indicate described navigation object to revert on the direction of benchmark route.If but the user is not when following the guide of described indication information, may cause described navigation object further to depart from the direction of described benchmark route, thereby away from the destination.At this moment, will recomputate navigation way according to current location and the destination of described navigation object according to the technical solution of the present invention guider, navigation object just can arrive the destination according to new navigation way like this.
The embodiment of the invention also provides a kind of guider, as shown in Figure 3 be the structural representation of the specific embodiment of a kind of guider of the present invention.
With reference to figure 3, described guider 1 comprises: drawing unit 11, be used for electronic chart draw navigation object from the departure place to the benchmark route of destination; Position determination unit 12 is for the current location information of determining described navigation object; Angle parameter determining unit 13 determines that for the current location information of the navigation object of determining based on described position determination unit 12 described navigation object is with respect to the angular deflection parameter of described benchmark route; Time parameter determining unit 14 is used for when the definite angular deflection parameter of described angle parameter determining unit 13 during greater than angle threshold, the opening entry time parameter, and wherein, described time parameter identifies described angular deflection parameter greater than the time of angle threshold; Indicating member 15, the time parameter that is used for determining when described time parameter unit 14 is greater than very first time threshold value and less than second time threshold, send indication information to the user, wherein said indication information is used to indicate on the direction that described navigation object revert to described benchmark route; And computing unit 16, the time parameter that is used for determining when described time parameter unit 14 is greater than described second time threshold, redefines navigation way based on current location information and the described destination of described navigation object.

Then, measure the current location information of described navigation object by described position determination unit 12, and it is presented on the electronic chart.Described current location information comprises the coordinate information of described navigation object on electronic chart.The current location that it will be appreciated by those skilled in the art that generally the described navigation object that gets access to by gps receiver represents that by gps coordinate described gps coordinate is to be based upon in the coordinate system of real world, is represented by longitude and two parameters of latitude.Guider need convert described gps coordinate to local Gauss plane coordinate, to realize the correct coupling of gps coordinate in electronic chart.The process that concrete gps coordinate converts local Gauss plane coordinate to is technology as well known to those skilled in the art, does not repeat them here.
