Fig. 2 shows the realization flow of the electronic map interest point marking method that the preferred embodiment of the present invention provides, and details are as follows:
In step S201, initialization two-dimensional matrix, point of interest record set and annotation threshold values;
As embodiments of the invention, two-dimensional matrix is used for simulating display window, the point of interest record set is used for writing down interest point information, but the annotation threshold values satisfies the maximal value of the element that the annotation zone of annotation condition comprised in two-dimensional matrix for the constraint circulation time, the initial value of annotation threshold values m can be set to 1, can have only a point of interest possibility annotation in the annotation zone.
In embodiments of the present invention, during initialization, all elements in the two-dimensional matrix is put 0, promptly without any mark, empty the point of interest record set, the annotation threshold value is set to initial value.
In step S202, the interest point information in the electronic map database is extracted in the point of interest record set;
In embodiments of the present invention, interest point information mainly contains longitude and latitude, type and the name information etc. of point of interest.
In step S203, from the point of interest record set, select symbol area to be arranged in the point of interest of display window, the symbol area of point of interest is done sign flag in two-dimensional matrix, and the delete mark zone is not arranged in the point of interest of display window from the point of interest record set;
In embodiments of the present invention, to each point of interest in the point of interest record set, calculate its symbol area, the if symbol zone is arranged in display window, and then sign flag is done in the corresponding region in two-dimensional matrix, otherwise deletes this point of interest from the point of interest record set.After the delete mark zone is not arranged in the point of interest of display window from the point of interest record set, can guarantee that the point of interest in the point of interest record set all is arranged in display window on the one hand, help to reduce the data volume of point of interest record set on the other hand, can discharge storage space, speed up processing.
The mark that the sign flag of point of interest in two-dimensional matrix can select any one can't eliminate in the annotation process, adopt in the embodiment of the invention the add up mode of a higher value of the element in the symbol area, for example the whole elements with corresponding region in the two-dimensional matrix add up 2000.
When there was priority in point of interest, as one embodiment of the present of invention, the point of interest that can be arranged in display window to the symbol area that point of interest writes down centralized recording carried out prioritization, preferentially obtains annotation to help the high point of interest of priority level.
In step S204, but analog mark is carried out at two-dimensional matrix in the annotation zone that point of interest is arranged in display window fully;
But the annotation zone of point of interest can be the zone of any direction around the point of interest symbol area.In embodiments of the present invention, with the right side of point of interest symbol area, zone last, left, four direction down is example, as shown in Figure 3, the right side, last, left, the following four direction of calculating point of interest symbol area can be placed the rectangular area Ri (i=0 of interest point marking information, 1,2,3), if rectangular area Ri in two-dimensional matrix, then carries out analog mark with the corresponding region of rectangular area Ri in two-dimensional matrix fully.In embodiments of the present invention, but but when being carried out mark, the annotation zone adopts the add up mode of a unit value of the element value that the annotation zone is comprised, but the element value that for example the annotation zone is comprised in two-dimensional matrix adds up 1.
In step S205, be docile and obedient preface and from the point of interest record set, extract the not point of interest of annotation, but the analog mark in the annotation zone of the current not annotation point of interest of detection in two-dimensional matrix;
In embodiments of the present invention, from the point of interest record set, extract in order and be arranged in the not point of interest of annotation of display window, be arranged in the analog mark of the annotation zone of display window fully but detect this point of interest at two-dimensional matrix, but the element value that the annotation zone of promptly current not annotation point of interest in two-dimensional matrix comprised.
In step S206, but judging what whether greatest member in the element that the annotation zone of current not annotation point of interest in two-dimensional matrix comprised had smaller or equal to the annotation threshold values, is execution in step S208 then, otherwise execution in step S207;
But, but just select this annotation zone to be this annotation zone of annotation point of interest not just when judging the greatest member have in the element that the annotation zone comprised smaller or equal to the annotation threshold values.
In step S207, but judging whether current not annotation point of interest has only an annotation zone, is execution in step S208 then, otherwise execution in step S210;
In embodiments of the present invention, if but point of interest has only an annotation zone that is arranged in display window fully, although should but the overlapping annotation of a plurality of points of interest may be arranged the annotation zone, can obtain annotation, but then preferential the selection should annotation zone this point of interest of annotation in order to guarantee this point of interest.
In step S208, but in two-dimensional matrix, should carry out the annotation mark to this point of interest in the annotation zone, and annotation is carried out to this point of interest in the zone corresponding with this simulation annotation zone in display window;
The annotation mark can be any one mark that can't eliminate in the annotation process, adopt whole elements in simulation annotation zone bigger value that adds up in embodiments of the present invention, and 2000 mode for example adds up.In the embodiment of the invention, when point of interest is obtained simulation annotation zone in the simulation display window after, adopt the mode of in display window, this point of interest being carried out annotation immediately, the annotation mark does not need to add in addition interest point information, also can write down simulation annotation zone earlier, during end to be detected together with the mode of point of interest annotation in display window.
In step S209, but cancel other annotation zone analog mark in two-dimensional matrix of this point of interest;
In embodiments of the present invention, but the mode that the element value that but the annotation zone is comprised owing to the analog mark employing to the annotation zone adds up, but the mode that therefore just can adopt element value that the annotation zone is comprised to successively decrease when cancelling analog mark for example subtracts 1 with the element value that the corresponding region comprised.In addition, because this point of interest is obtained annotation at display window, and cancelled its analog mark in two-dimensional matrix, therefore, as one embodiment of the present of invention, this point of interest can be deleted from the point of interest record set, thus the length of minimizing point of interest record set, the cycle detection speed of quickening point of interest.
In step S210, judge whether whole points of interest in the point of interest record set circulate to finish, be execution in step S211 then, otherwise return execution in step S205 that choosing not, the annotation point of interest continues to detect;
In step S211, according to the value of the element in the two-dimensional matrix before and after point of interest record set cycle detection, judge whether two-dimensional matrix changes, and is then to return execution in step S205, otherwise execution in step S212;
If two-dimensional matrix changes, represent that the rarest point of interest obtained annotation in epicycle circulation, but the analog mark in other annotation zone of this point of interest is cancelled, mean that other points of interest still may obtain annotation under current annotation threshold values condition, therefore return execution in step S205, once more the not annotation point of interest in the point of interest record set is carried out cycle detection, to give other not possible annotation zones of annotation point of interest searching.If two-dimensional matrix does not change, represent has no stomach for to put after the loop ends can obtain annotation, then execution in step S212.
In step S212, judge whether the annotation threshold values reaches the maximal value of setting, is then to finish, otherwise execution in step S213;
In embodiments of the present invention, the maximal value of annotation threshold values can rule of thumb be provided with, purpose is in order to make more point of interest can obtain annotation, for example but whole annotations zone of a point of interest all is overlapping annotation in the cycle detection, then obviously when annotation threshold values m=1, this point of interest has no chance to obtain annotation, if transfer big annotation threshold value, for example during m=2, then point of interest might be obtained annotation.
In step S213, transfer big annotation threshold values, return execution in step S205.
In the embodiment of the invention, can determine the amplitude that the annotation threshold values increases according to actual conditions, generally on the basis of original annotation threshold values, add 1, but expression when the situation of the possible overlapping annotation of 1 point of interest Duo in annotation zone than last round of circulation under, point of interest can be obtained annotation.
