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 present invention are shown in the drawings, it should be understood that the present invention may 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 visual use experience of users, contents such as some moving pictures and videos can be set at some positions in some electronic history maps and displayed when the users need the contents, so that the effect of dynamic display in the history electronic maps is achieved. In the display mode, contents such as a moving picture video and the like to be displayed in the historical map are preset and displayed when the user needs. However, in practical use, the historical map information in the above scheme is realized based on pre-recorded video or moving pictures, which makes it necessary to edit the moving pictures or video again when the historical map information needs to be adjusted, that is, when the dynamic information in the electronic historical map needs to be modified or adjusted, the convenience of the modification process is often poor due to the need to edit the video or moving pictures 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, where the method includes:

101. the target elements to be displayed are determined in the map.

The target element is part of image information required by the map in the display process.

In this embodiment, the target element to be displayed may be understood as an image to be displayed in a part of the total display content in the electronic map, for example, a mountain, a river, a city, a country, etc. Because the scheme of the implementation is used for displaying map information when a user uses an electronic map, that is to say, in the displaying process, it is generally required to determine what target elements the user wants to display, namely, the target elements to be displayed.

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

The target display mode is used for controlling target elements to execute display operation according to at least one non-repeated position in the map so as to enable the target elements to form a dynamic change display effect, the target elements are display elements for achieving the display effect of the target elements, and specifically, the target elements can be a point, a line or a plane capable of forming the display effect of the target elements. Of course, according to the different specific target elements, the specific corresponding target elements and the corresponding display modes are also different.

After the target elements to be displayed are determined, the display mode of the target elements is changed due to different forms of the target elements, for example, the display mode of a river and the display mode of a city may be different. In addition, in this embodiment, since the display mode is based on the change of the position output of the target element, the corresponding display mode needs to be acquired based on the determined target element in this step based on the target element determined in the foregoing step. In addition, in this embodiment, the presentation mode may be understood as that the control target element is displayed at least once in a non-repeated position in the map. Thus, the dynamic display effect of the target elements to be displayed can be realized through different 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, assuming that the target element is a footprint, the dynamic effect of "moving" the target element footprint can be formed by sequentially displaying the target element a at the position a, the position b, and the position c during the presentation 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 the subsequent user needs to adjust the dynamic display effect of the target element, the adjustment process of the dynamic display effect of the target element is simplified, and the mode of modifying the dynamic display effect is more convenient.

Based on this, the method for displaying the history information in the history map provided by the embodiment of the invention solves the problems existing in the prior art by determining the target element to be displayed in the map, then acquiring the corresponding target display mode according to the target element, and finally outputting the target element in the map according to the target display mode, thereby realizing the function of displaying the history information in the history map. In the above scheme, the target element is part of the image information required by the map in the display process, and the target display mode is realized by controlling the target element to execute the display operation according to at least one non-repeated position in the map, so that the target element can be displayed on the non-repeated position when the target element is output according to the target display mode, the target element can form a dynamic change display effect, the dynamic display function of the target element based on the position change display of the target element is realized, the content which the user wants to know can be prominently displayed, the problem that the user is influenced by the existing stiffer display mode to intuitively 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 based on the display effect of the target element realized by the display operation executed at least once at the non-repeated position, so that the dynamic display effect of the display mode does not relate to a moving picture or a video, but the change of the overall dynamic display effect of the target element can be realized based on the adjustment and the modification of different positions, thereby avoiding the problem of poor convenience in the modification process caused by the video or the moving picture reediting in the conventional map information display process, and being capable of adjusting the position of the target element for executing the display operation as required by a user, thereby improving the convenience of modifying the dynamic display effect of the map information.

In some embodiments, the target elements may include point elements, line elements, and plane elements. The punctiform element can be understood as a punctiform display image, for example a city displayed in punctiform form in a map; the line element can then be understood as a line-shaped display image, for example a river in the map represented by a line; the planar element is then understood to be a display image in the shape of a region, for example a country represented by a region in a map.

Because the types of the target elements may be any of the three types, the display modes required in the display process of the target elements may also be changed according to the specific types of the target elements, so the step 102 of obtaining the corresponding target display modes according to the target elements in the foregoing embodiment may specifically include, when executed:

and determining a display mode corresponding to the target element according to a corresponding relation as the target display mode, wherein the corresponding relation comprises each target element and a corresponding display mode, and the display modes comprise a punctiform element display mode, a linear element display mode and a planar element display mode. It should be noted that, before the step is executed in actual application, a corresponding display mode may be set for each different target element based on the corresponding display mode, and a corresponding relationship between the display mode and the type of the target element is recorded, so that it is ensured that when the step is executed, the display mode corresponding to the current target element can be directly obtained based on the corresponding relationship to be used as the target display mode.

In the above steps, since the target display mode is determined according to the type of the target element based on the preset corresponding relation, 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, and therefore the accuracy of the subsequent display based on the target display mode is ensured.

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

at this time, in step 103 of the foregoing embodiment, outputting the target element in the map according to the target exhibition mode may include:

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

then, selecting at least one coordinate different from the known coordinate to be output as a coordinate to be output according to a first selection rule from a coordinate set by the punctiform element display mode,

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 coordinates which are different from the used coordinates in 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 for selecting the coordinates from the coordinate set;

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

When the above steps are specifically performed, 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 may be randomly selected to form the coordinate set. Thus, when coordinates need to be selected to output the point element in this step, the point element may be selected from the coordinate set, such as coordinate 1, coordinate 2, or even coordinate N. In addition, when outputting the point element, in order to avoid that the coordinates of the current point element coincide with the coordinates already used, the coordinates selected for the point element are different from the coordinates already used, i.e. the influence in the previous moment is avoided. 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 includes a point element, the manner in which the point element is output may also be used as a range of coordinates of the selected output point element in a certain area based on the user's setting in some cases. Based on this, in step 103 of the foregoing embodiment, outputting the target element in the map according to the target exhibition mode may further include, when executed:

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

then, selecting at least two coordinates different from the position of the known used coordinate from a position area as coordinates to be output according to a second selection rule, 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 coordinates different from the position of the used 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 coordinates from the position area;

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 element, a function of selecting the coordinates of the point element output from the setting area can be implemented, so that the mode of selecting the coordinates to be output is more convenient, the coordinates of the points do not need to be set one by one in advance, only the location area is deployed, and thus, the problem of large workload caused by one-to-one setting of the coordinates when a large number of coordinates need to be set to output the point element is ensured.

In some embodiments, since the selection order can determine the output order of the subsequent target elements, since the difference in the selection order will directly affect the change of the output order of the target elements, thereby affecting the display effect of the target elements, the selection order may include: a reciprocating sequence and a cyclic sequence,

The reciprocating sequence is used for enabling the dot elements to realize reciprocating movement of the dot elements in a non-closed path after being output, and the circulating sequence is used for enabling the dot elements to realize movement of the dot elements in a clockwise direction in the closed path after being output.

Through the reciprocation sequence, as shown in fig. 2-D, the dot elements can be reciprocally output in order between the start points and the stop points of the path, that is, from the end point a to the end point B, so that the dot elements exhibit a reciprocal movement effect in the non-closed path. In addition, by the circulation order, as shown in fig. 2-E, the dot elements can be sequentially circulated and outputted according to the path, so that the dot elements exhibit a circulation effect in a closed path, wherein the circulation manner includes a clockwise direction and a counterclockwise direction. Therefore, based on the reciprocating sequence and the circulating sequence, the moving effect of the dot elements of different types is realized, and the requirements of users for displaying the dot elements based on different modes can be enriched.

In some embodiments, in some cases, the user may need to display a linear image, such as a river, a ridge, or the like, that is, need to display the linear element, where displaying the linear element may be performed by using an element that may represent the whole of the linear element, that is, a line element, on the one hand, and may also be performed according to a point element on the other hand.

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

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

In this step, since the first set includes coordinates covered when the line element is displayed, it is possible to ensure that the point element is output at the position of the line element on the basis of the output of the line element, thereby realizing the effect of displaying the point in the line, such as a water spray on a river or a ship on a river. Where a river may be understood as a line element and a water spray or a ship may be understood as a dot element.

In addition, the first set further comprises coordinates which are smaller than a preset distance from the coordinates covered by the line elements during display, so that the coordinates covered by the line elements can be displayed nearby the coordinates covered by the line elements during display of the line elements, the function of simultaneously giving consideration to display of the point elements during display of the line elements is achieved, and the display effect is enriched. And when the display effect of the linear element needs to be adjusted, the whole adjustment effect of the linear element can be realized by directly adjusting the linear element, so that when the whole of the linear element needs to be changed, the whole modification process can be simplified.

On the other hand, in some embodiments, when a line element is shown by a dot element, the dot element includes a first dot element and a second dot element; based on this, the outputting the target element in the map according to the target exhibition 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 element through the linear element display mode, sequentially selecting coordinates from a second set according to the selection sequence, and outputting the second point element according to the preset time interval. The linear element coordinate set includes coordinates for forming the linear element, and the second set includes coordinates of the linear element coordinate set and coordinates having a distance from the coordinates covered when the linear element is formed and displayed smaller than a preset range.

In this way, the first dot element is output to display the linear element, and the second dot element is used as the dot element displayed on the linear element, so that the effects of the linear element and the dot elements near the linear element are realized by the dot element, and when a small part of the display effects of the linear element needs to be adjusted, the first dot element at the corresponding position can be directly adjusted, and the local adjustment process of the display effects of the linear element is simplified.

In some embodiments, when the planar element needs to be displayed, different display modes are selected based on the specific setting mode of the planar element, wherein one display mode can be based on the whole display mode of the planar element, and the other display mode can be a mode of forming the planar element in a dot element mode.

Based on this, when the display effect of the planar element is achieved by the dot elements, the dot elements include a first dot element and a third dot element;

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

Since the third set includes coordinates forming the planar element, the first point element is output through the coordinates in the third combination, so that the display effect of the planar element by the first point element is realized, and meanwhile, the coordinates are selected again from the third set at intervals of time and the third point element is output, so that the effect of displaying the point element on the planar element is realized, for example, the capital is displayed in a country region, wherein the country can be the display of the first point element simultaneously output, and the capital is the display of one coordinate output selected in the country by the third point element.

Through the process, the planar elements are displayed by the first point elements, the specific point elements can be displayed in the planar elements, and the linear elements can be formed based on the combination of the third point elements, so that the display effect is enriched. In addition, as the planar element is formed by countless 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 the planar element, the target element further includes a planar element, where the planar element may be understood as a planar image preset by a user.

Based on this, the outputting the target element in the map according to the target exhibition mode in step 103 in the foregoing embodiment may specifically include:

outputting the surface element according to the surface element coordinate through the surface element display mode, sequentially selecting the coordinates from the fourth set through the selection sequence, and outputting the point element according to the preset time interval. The fourth set is coordinates covered by the surface element during display and coordinates with a distance smaller than a preset range from the coordinates covered by the surface element during display.

By the method, the planar elements can be displayed as a whole on the surface element, the display effect of the dot elements in the planar elements is realized by the dot elements on the basis of the planar elements, meanwhile, the dot elements can form the linear elements according to the coordinates and the output sequence, that is, the combined effect of simultaneously displaying the linear elements and the planar elements can be realized, and the display effect is enriched. In addition, since the planar element is displayed through the whole display of the surface element, the planar element can be directly modified through the surface element when the whole adjustment of the surface element is needed, for example, when the position is changed, and each point in the surface element is not needed to be adjusted, so that the adjustment and modification processes are simplified.

In some embodiments, the surface element comprises at least two sub-surface 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 output interval of the sub-surface elements is consistent with the output interval of the point elements and the line elements in the display process, the preset frequency in the step can be corresponding to the time interval of the point elements and the line elements.

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

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

Before outputting the target element in the map according to the target exhibition 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 correspondence, wherein the event correspondence comprises the historical event information corresponding to each target element. Because the position and the mode of each history event to be displayed are different, in this embodiment, different target elements may be set in advance according to the event correspondence, and a specific corresponding mode may be selected according to the actual needs of the user, which is not limited herein.

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

For example, when the history event information is a collar expansion, the target element may be a planar element, and when the planar element is displayed in this step, the event indicating that the collar expansion occurs in the history map is displayed in the form of a display of the planar element. For another example, when the history event is a zhaojun plug, the target element is a line element corresponding to a route for displaying the zhaojun plug, and the text of the zhaojun plug may be outputted in a manner of displaying the line element.

According to the method, the corresponding historical event information can be displayed according to the corresponding display mode based on the forms of different target elements, so that the effect of displaying the historical event 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 the present embodiment is applied to a map, there are cases where the user adjusts the display scale, such as zoom in, zoom out, etc., and since there may be differences between the contents displayed in 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 proportion of the map is changed or not;

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

Since the change of the display scale will directly affect the content to be displayed after the change, that is, the originally determined target element may need to be determined again, for example, when the display scale corresponds to each national right, the target element may correspond to the punctual element 1 of the capital of each right, and when the display scale is enlarged, the target element 2 corresponding to the province of the certain province of the right may need to be displayed. Therefore, by judging whether the user adjusts the display proportion through the above process and re-determining the target element based on the change mode after determining that the display proportion is adjusted, the method of the embodiment can realize the effect of adjusting the target element to be displayed after adjusting the display proportion, so that the method of the embodiment can meet the requirement that the display content changes with different display proportions, and enriches the use scene of the method of the embodiment.

In some embodiments, as can be seen from the description of the foregoing embodiments, when the display scale is changed, the target element needs to be redetermined, that is, the target element changes with the changing manner; in this embodiment, the target element includes a first target element and a second target element, where the first target element is an element before the change, and the second target element is an element after the change;

The re-determination of the target element according to the variation in the foregoing steps may be performed based on the specific implementation manner of the display scale adjustment, which includes the following aspects:

on the one hand, when the change mode is amplification and the first target element is a dot-shaped 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 amplification 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 still another aspect, when the variation is a 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;

in still another aspect, when the variation is a 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 foregoing processes performed in the foregoing aspects, the element adjustment rule may be understood as a rule preset by a user and in which case the target element needs to be reset only when the proportion is adjusted, and the specific setting manner and definition of the rule may be selected based on the actual needs of the user, which is not limited herein specifically.

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