Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to 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 invention to those skilled in the art.

In order to meet the convenient and intuitive use experience of a user, contents such as a certain moving picture video and the like can be arranged at certain positions in certain electronic history maps and displayed when the user needs, so that the effect of dynamic display in the history electronic maps is realized. In this display method, contents such as moving picture videos to be displayed in the history map are preset and displayed as needed by the user. However, in actual use, the history map information in the above scheme is implemented based on a pre-recorded video or moving picture, so that when the history map information needs to be adjusted, the moving picture or video needs to be edited again, that is, when the dynamic information in the electronic history map needs to be modified or adjusted, the convenience of the modification process is often poor due to the fact that the video and the moving picture need to be edited again.

In view of this, an embodiment of the present invention provides a method for displaying history information in a history map, as shown in fig. 1, the method includes:

101. and determining the target elements to be displayed in the map.

The target elements are partial image information required by the map in the display process.

In this embodiment, the target elements to be displayed may be understood as images that need to be displayed in a part of the entire display content in the electronic map, such as mountains, rivers, cities, countries, and the like. Since the scheme described in this embodiment is used to display the map information when the user uses the electronic map, that is, it is generally necessary to determine what target element the user wants to display currently, i.e., the target element to be displayed.

102. And acquiring a corresponding target display mode according to the target elements.

The target display mode is used for controlling a target element to perform display operation in the map according to at least one non-repeated position so as to enable the target element to form a dynamically-changing display effect, the target element is a display element for realizing the display effect of the target element, and specifically, the target element may be one point, one line or one surface capable of forming the display effect of the target element. Of course, according to the difference of the specific target elements, the specific corresponding target elements and the corresponding display modes are also different.

After the target elements needing to be displayed are determined, the display mode of different target elements is changed due to different forms, for example, the display mode of rivers is possibly different from the display mode of cities. In addition, in the present embodiment, since the presentation mode is a dynamic change of the target element based on a change in the position output of the target element, it is necessary to acquire a corresponding presentation mode based on the target element determined in the above step in this step. In addition, in this embodiment, the display manner may be understood as displaying the control target element at least once in a non-repetitive position in the map. Therefore, the dynamic display effect of the target elements to be displayed can be realized through the difference of the display positions.

103. And outputting the target elements in the map according to the target display mode.

After the display mode of the target element is determined, how to control the target element to output is actually determined, so that the dynamic display effect of the target element is realized. For example, as shown in fig. 2-a, if the target element is a footprint, then a dynamic effect of "moving" the footprint of the target element may be created by sequentially displaying the target element a at position a, position b, and position c during the presentation process described in this embodiment. The mode based on the embodiment is actually based on the adjustment of the display mode when the target element is output to realize the dynamic change of the target element, so that the position and the display mode of the target element can be directly adjusted when a subsequent user needs to adjust the dynamic display effect of the target element, thereby simplifying the adjustment process of the dynamic display effect of the target element and being more convenient and faster in the mode of modifying the dynamic display effect.

Based on this, for the problems in the prior art, the method for displaying historical information in a historical map provided by the above embodiment of the invention determines the target elements to be displayed in the map, then obtains the corresponding target display mode according to the target elements, and finally outputs the target elements in the map according to the target display mode, thereby realizing the function of displaying the historical information in the historical map. In the above scheme, because the target element is partial image information required by the map in the display process, and the target display mode is realized by controlling the target element to perform display operation according to at least one non-repeated position in the map, the target element can be displayed on the non-repeated position when the target element is output according to the target display mode, so that the target element forms a dynamically-changed display effect, a dynamic display function of the target element based on position change display of the target element is realized, the content which the user wants to know can be highlighted, the problem that the existing rigid display mode influences the user to visually know the required content is solved, and the display effect of the historical map is obviously improved. Meanwhile, the display mode of the historical information in the historical map is the display effect of the target element realized by performing display operation on the target element at least once non-repeated position, so the dynamic display effect does not relate to a dynamic image or a video, and the change of the whole dynamic display effect of the target element can be realized based on adjustment and modification of different positions, thereby avoiding the problem of poor convenience of the modification process caused by re-editing of the video or the dynamic image in the conventional map information display process, and only needing to adjust the position of the target element for performing display operation when required by a user, so the convenience of modifying the dynamic display effect of the map information is improved.

In some embodiments, the target elements may include point elements, line elements, and planar elements. A dot element may be understood as a dot display image, such as a city displayed in dots on a map; a linear element may be understood as a linear display image, such as a river represented by a line in a map; the area element may be understood as a display image of a shape of a region, for example, a country represented by a region in a map.

Based on this, since the type of the target element may be any of the three types, and therefore, the display manner required in the display process of the target element varies according to the specific type of the target element, the obtaining the corresponding target display manner according to the target element in step 102 of the foregoing embodiment may specifically include, when executed:

and determining a display mode corresponding to the target element according to the corresponding relation as the target display mode, wherein the corresponding relation comprises each target element and the corresponding display mode, and the display modes comprise a point element display mode, a linear element display mode and a planar element display mode. In practical applications, before the step is executed, corresponding display manners may be set for different target elements based on the different target elements, and the corresponding relationship between the display manners and the types of the target elements is recorded, so that it is ensured that the display manner corresponding to the current target element can be directly obtained as the target display manner based on the corresponding relationship when the step is executed.

In the above step, since the target display mode is determined according to the type of the target element based on the preset corresponding relationship, it is ensured that the target display mode finally determined in the process of obtaining the display mode is the type of the corresponding target element, thereby ensuring the accuracy in the subsequent display based on the target display mode.

In some embodiments, the display mode adopted in the display process based on the target element is implemented based on the output position of the target element, so that the subsequent display mode is different based on the specific category of the target element, specifically, when the target element comprises a point element;

in this case, the step 103 of the foregoing embodiment may output the target element in the map according to the target display manner, and the execution may include:

firstly, determining the used coordinates according to the position of the displayed content in the map, wherein the used coordinates are the coordinates for displaying the displayed content at the previous moment;

then, through the point-like element display mode, at least one coordinate different from the position of the known using coordinate is selected from the coordinate set according to a first selection rule to be used as a coordinate to be output,

Then, setting an output queue for the coordinates to be output according to the selection sequence, wherein the coordinate sequence in the output queue is consistent with the coordinate sequence of the selection sequence, the coordinate set is constructed by at least two coordinates preset in the map, the first selection rule is used for selecting the coordinates different from the used coordinates from the coordinate set according to a preset time interval, the first selection rule comprises the selection sequence, and the selection sequence is used for determining the sequence of selecting the coordinates from the coordinate set;

and finally, sequentially outputting the point elements in the coordinates to be output according to the output queue.

When the above steps are executed specifically, in order to achieve the effect of selecting the coordinates to be output from the coordinate set, different coordinates may be preset and the coordinate set may be formed, and as shown in fig. 2-B, a plurality of coordinates are randomly selected to form the coordinate set. Thus, when coordinates are required to be selected to output the point element in this step, the coordinates may be selected from the set of coordinates, such as coordinate 1, coordinate 2, or even coordinate N. In addition, when outputting the point elements, in order to avoid the coordinates of the current point element coinciding with the coordinates already used, the coordinates selected for the point element are different from the coordinates already used, i.e. to avoid the internal influence exhibited at the previous moment. In addition, in the selecting process, when the coordinates of the point elements to be output are multiple, a corresponding output queue can be set according to the selecting sequence, so that the point elements are sequentially output according to the output queue, the effect of sequentially outputting the point elements according to the coordinates of the selecting sequence is formed, and the dynamic change effect of the point elements is realized.

In some embodiments, when the target element comprises a point element, the manner of outputting the point element may also be based on a user's setting in a certain area as a range of selected output point element coordinates in some cases. Based on this, the outputting the target element in the map according to the target displaying manner in step 103 of the foregoing embodiment may further include, when executed:

firstly, according to the position of the displayed content in the map, determining the used coordinate;

then, selecting at least two coordinates different from the position of the known using coordinate from a position area as a coordinate to be output according to a second selection rule in a dot element display mode, wherein the position area is an area preset in the map, the position area at least comprises two coordinates, the second selection rule is used for selecting the coordinate different from the position of the using coordinate from the position area according to a preset time interval, the second selection rule comprises the selection sequence, and the selection sequence is used for determining the sequence of selecting the coordinate from the position area;

then, setting an output queue for the coordinates to be output according to the selection sequence, wherein the coordinate sequence in the output queue is consistent with the coordinate sequence of the selection sequence;

Based on the above steps, as shown in fig. 2-C, by selecting the coordinates to be output in the location area, such as coordinates 1, 2 to N, as the coordinates of the subsequent output point elements, a function of selecting the output coordinates of the point elements from the set area can be realized, so that the manner of selecting the coordinates to be output is more convenient, the point coordinates do not need to be set one by one in advance, only the location area is deployed, and thus the problem of a larger workload caused by setting the coordinates one by one when a large number of coordinates are required to be set to output the point elements is ensured.

In some embodiments, since the selection sequence can determine the output sequence of the subsequent target element, the change of the output sequence of the target element will be directly affected due to the difference of the selection sequence, so as to affect the display effect of the target element, and therefore, in practical applications, the selection sequence may include: the reciprocating sequence and the circulating sequence are carried out,

Through the reciprocating sequence, as shown in fig. 2-D, the point elements can be output back and forth in sequence between the start point and the end point of the path, namely from the end point a to the end point B, so that the point elements can present a reciprocating movement effect in the non-closed path. In addition, through the circulation sequence, as shown in fig. 2-E, the point elements can be sequentially and circularly output according to the paths, so that the point elements can present a circular effect in the closed path, wherein the circular manner includes clockwise direction and counterclockwise direction of the clock direction. Therefore, based on the reciprocating sequence and the circulating sequence, the moving effect of different types of point elements is realized, and the requirements of users for displaying the point elements based on different modes can be enriched.

In some embodiments, in some cases, what the user needs to show may also be an image of a line type such as a river, a ridge, etc., i.e., a line element needs to be shown, where the showing of the line element may be performed by using an element that can characterize the entirety of the line element, i.e., the line element, on the one hand, and may also be performed by the dot element in its entirety on the other hand.

Based on this, the process of displaying the linear elements can be performed based on the following two ways, respectively:

on one hand, when the target element further includes a line element, the outputting the target element in the map according to the target showing manner in step 103 of the foregoing embodiment may include, when executed:

In this step, since the first set includes the coordinates covered when the line element is displayed, it is ensured that the point element is output at the position of the line element on the basis of the output of the line element, thereby achieving the effect of displaying the point in the line, such as water splash on a river or a ship on a river. Where a river is to be understood as a line element and a water bloom or vessel as a point element.

In addition, the first set also comprises a coordinate which is less than the preset distance from the coordinate covered by the line element during displaying, so that the point element can be displayed near the coordinate covered by the line element during displaying, the function of displaying the point element can be realized during displaying the line element, and the display effect is enriched. Moreover, when the display effect of the linear elements needs to be adjusted, the overall adjustment effect of the linear elements can be realized by directly adjusting the linear elements, so that when the overall of the linear elements needs to be changed, the overall modification process can be simplified.

On the other hand, in some embodiments, when a line element is shown by a point element, the point element includes a first point element and a second point element; based on this, the outputting the target element in the map according to the target displaying manner in step 103 of the foregoing embodiment may further include:

and selecting coordinates from a linear element coordinate set to output the first point elements in the linear element display mode, sequentially selecting the coordinates from a second set according to the selection sequence, and outputting the second point elements according to the preset time interval. The linear element coordinate set comprises coordinates for forming the linear elements, and the second set comprises the coordinates of the linear element coordinate set and coordinates with a distance smaller than a preset range from the coordinates covered when the linear elements are displayed.

In this way, the linear element is displayed by outputting all the first point elements, and the second point elements are used as the point elements displayed on the linear element, so that the linear element and the point elements near the linear element are realized by the point elements.

In some embodiments, when the planar element needs to be displayed, different display manners are selected based on the specific arrangement manner of the planar element, one of the display manners may be based on the entire planar element, and the other display manner may be that the planar element is configured in a point element manner.

Based on the above, when the display effect of the planar element is realized by the point element, the point element includes a first point element and a third point element;

in the foregoing embodiment, the outputting the target element in the map according to the target displaying manner in step 103 may include:

Since the third set includes coordinates forming the planar element, outputting the first point element through the coordinates in the third combination realizes the effect of displaying the planar element with the first point element, and simultaneously selecting the coordinates again at time intervals from the third set and outputting the third point element, realizes the effect of displaying the point element on the planar element, for example, displaying the capital in a national region, wherein the "country" may be displayed by outputting the first point element at the same time, and the "capital" is displayed by outputting one coordinate selected by the third point element in the planar element of the "country".

Through the above process, the planar element can be displayed by the first point element, and the specific point element can be displayed in the planar element, and the linear element can be formed based on the combination of the third point elements, so that the display effect is enriched. Moreover, since the planar element is formed by the infinite number of first point elements, when the display effect of the planar element needs to be partially adjusted, the first point elements of the portion needing to be adjusted can be directly adjusted, so that the whole adjustment is not needed, and the process of adjusting the dynamic display effect of the planar element is simplified.

In some embodiments, when the display effect of the planar element needs to be achieved through a surface element, the target element further includes a surface element, wherein the surface element can be understood as a planar image preset by a user.

Based on this, in the foregoing embodiment, the outputting the target element in the map according to the target displaying manner in step 103 may specifically include, when executed:

and outputting the surface elements according to the surface element coordinates in the surface element display mode, sequentially selecting the coordinates from a fourth set according to the selection sequence, and outputting the point elements according to the preset time interval. And the fourth set is the coordinates covered when the surface element is displayed and the coordinates, the distance between the coordinates covered when the surface element is displayed and the coordinates covered when the surface element is displayed is smaller than a preset range.

By the method, the planar element can be displayed as a whole, the display effect of the point-shaped element in the planar element can be realized through the point element on the basis of the planar element, meanwhile, the point element can form the linear element according to the coordinate and the output sequence, namely, the combined effect of simultaneously displaying the linear element and the planar element can be realized, and the display effect is enriched. In addition, since the planar element is displayed integrally through the planar element, the planar element can be directly modified through the planar element when the overall planar element needs to be adjusted, for example, when the position changes, each point in the planar element does not need to be adjusted, and therefore the adjustment and modification processes are simplified.

In some embodiments, the bin elements comprise at least two sub-bin elements;

It should be noted that the preset frequency in this embodiment may correspond to the time interval in the foregoing embodiment, or may be different, and the specific situation may be determined based on the display effect required by the user. For example, when the user needs to make the output intervals of the point elements and the line elements consistent in the display process between the sub-surface elements, the preset frequency in this step may be made to correspond to the time intervals of the point elements and the line elements.

Specifically, as shown in fig. 2-F, transition may be performed from the sub-surface element a to the sub-surface element B, and since the display sequence of each sub-surface element is set according to the display order in the display process, accuracy of the sequence between the sub-surface elements in the display process can be ensured, and meanwhile, since the sub-surface element displayed at the previous time is implemented in a gradual change manner when the sub-surface element displayed at the previous time passes through the sub-surface element at the next time, a relatively smooth transition manner is implemented, so that a sensory effect of a user is better, and an abrupt feeling caused by a sudden change is avoided.

In some embodiments, when the method described in the foregoing embodiment is applied to a map scene of historical events, the target element in the foregoing embodiment may actually be understood as a historical event that needs to be presented, and thus, the target element corresponds to at least one piece of historical event information;

before outputting the target element in the map according to the target showing manner in step 103 in the foregoing embodiment, the method further includes:

and determining the historical event information corresponding to the target elements according to event corresponding relations, wherein the event corresponding relations comprise the historical event information corresponding to each target element. Since the positions and manners of each historical event to be displayed are different, different pieces of historical event information may be set as corresponding target elements in advance based on the event correspondence in the embodiment, and the specific corresponding manner may be selected based on the actual needs of the user, which is not limited herein.

Further, in the foregoing embodiment, the outputting the target element in the map according to the target display manner in step 103 may specifically include:

For example, when the historical event information is a territorial expansion, the target element may be a planar element, and when the planar element is displayed in the step, the event of the territorial expansion is displayed in a display form of the planar element when the occurrence of the territorial expansion in the historical map is represented. For example, when the historical event is shoujun who shows the course of shoujun.

According to the method, the corresponding historical event information can be displayed according to the corresponding display mode based on different target element forms, so that the effect of displaying the historical events while displaying the target elements is ensured, and the display effect of the historical information in the historical map is richer.

In some embodiments, since the method described in this embodiment is applied to a map, there are cases where a user adjusts a display scale, such as zooming in, zooming out, and the like, and since there may be differences in displayed contents of different display scales, before outputting the target element in the map according to the target display manner in step 103 of the foregoing embodiment, the method further includes:

judging whether the display scale of the map changes;

and re-determining the target element according to the change mode.

Since the change of the display scale directly affects the content to be displayed after the change, that is, the originally determined target element may need to be re-determined, for example, when the display scale corresponds to the administrative rights of each country, the target element may correspond to the dot element 1 of the capital of each administrative right, and when the display scale is enlarged, the dot element 2 corresponding to the province of a certain province of the administrative right may need to be displayed. Therefore, whether the display scale is adjusted by the user is judged through the process, and after the display scale is determined to be adjusted, the target element is re-determined based on the change mode, so that the method of the embodiment can realize the effect of adjusting the target element to be displayed after the display scale is adjusted, the method of the embodiment can meet the requirement that the display content under different display scales changes along with the change of the display content, and the use scene of the method of the embodiment is enriched.

In some embodiments, based on the description of the foregoing embodiments, when the display scale changes, the target element needs to be determined again, that is, the target element changes with the change manner; in this embodiment, the target elements include a first target element and a second target element, where the first target element is an element before change and the second target element is an element after change;

therefore, the step of re-determining the target element according to the change mode can be divided into the following aspects based on the specific implementation mode when the display scale is adjusted, wherein the following aspects include:

on one hand, when the change mode is amplification and the first target element is a dot element, determining whether the first target element needs to be adjusted to the second target element according to an element adjustment rule, wherein the element adjustment rule comprises element adjustment modes corresponding to different display proportions;

on the other hand, when the change mode is enlargement and the first target element is a linear element, determining whether the first target element needs to be adjusted to the second target element according to an element adjustment rule;

in another aspect, when the change mode is reduction and the first target element is a planar element, determining whether the first target element needs to be adjusted to the second target element according to an element adjustment rule;

on the other hand, when the change mode is reduction and the first target element is a linear element, determining whether the first target element needs to be adjusted to the second target element according to an element adjustment rule;

In the processes performed in the foregoing aspects, the element adjustment rule may be understood as a rule that is preset by a user and needs to reset the target element only when the adjustment ratio is reached, and the specific setting manner and the definition of the rule may be selected based on the actual needs of the user and are not specifically limited herein.

Through the above modes, the first target element can be adjusted to the second target element by selecting the corresponding mode under different change modes, so that each change mode can find the corresponding target element adjustment process, and the accuracy of re-determining the target element is ensured.
