[0001] The present application relates to the field of map drawing technology, and in particular to a method, device, equipment and storage medium for generating map point names. Background Art

[0002] A map generally includes multiple regions, and each region needs to display the corresponding point name at its center. For example, if the map of City A includes District B, the point name "District B" needs to be displayed at the center of District B. Therefore, when drawing the map, the corresponding point name needs to be generated at the center of the region.

[0003] Currently, ECharts (Enterprise Charts, commercial-grade data charts) and other tools can be used for map drawing. However, since the edges of regions in maps are often irregular in shape, the center position calculated based on the edges of the regions is inaccurate, which makes it difficult to generate point names at the true center of the regions in the map. Summary of the invention

[0004] In order to facilitate the generation of a point name at the true center position of an area in a map, the present application provides a method, apparatus, device and storage medium for generating a map point name.

[0009] The target center point is determined based on the information of the corner points of the plurality of orientation quadrilaterals, and a corresponding point name is generated at the target center point.

For example, ECharts (Enterprise Charts, commercial data charts) and the like are used to draw an electronic version of the map; the map in this embodiment includes maps of different levels, and the levels can specifically be administrative levels. For example, the maps include national maps, provincial maps, municipal maps, district maps...; this embodiment takes the municipal map as an example to illustrate the map; the municipal map includes multiple district-level areas. For example, the municipal map includes area A, area B, area C..., and each area in the municipal map is also a region; it should be noted that if the map is a provincial map, then each city in the provincial map is also a region, and so on; the boundary of the region in the map is also the boundary of the region, and the boundary of the region is composed of multiple continuous boundary points.

It should be noted that, due to the irregularity of the regional boundary, the primary center point is generally not the actual center point of the corresponding region.

[0034] Specifically, the boundaries of the districts included in the city-level map are determined to obtain the regional boundaries, and then the longitude and latitude coordinates corresponding to each boundary point in the regional boundaries are determined, and the boundary longitude and latitude coordinate set contains the longitude and latitude coordinates corresponding to each boundary point in the regional boundaries; further, the center point of the corresponding district is calculated based on the boundary longitude and latitude coordinate set, and the center point is recorded as the primary center point.

[0041] S140, determining a target center point based on the information of multiple orientation quadrilateral corner points, and generating a corresponding point name at the target center point.

[0042] Among them, each orientation quadrilateral corner point information can construct a corresponding quadrilateral through the latitude and longitude coordinates of the first corner point, the latitude and longitude coordinates of the second corner point, the latitude and longitude coordinates of the third corner point, and the latitude and longitude coordinates of the fourth corner point, and the quadrilateral is recorded as an orientation quadrilateral; four orientation quadrilaterals can be constructed through the four orientation quadrilateral corner point information, and based on the four orientation quadrilaterals, a quadrilateral located at the true midpoint area of ​​the region can be further determined, and the quadrilateral is recorded as the target quadrilateral, and the center point of the target quadrilateral is recorded as the target center point; further, a point name corresponding to the region can be generated at the target center point.

[0043] Specifically, four orientation quadrilaterals are constructed according to the corner point information of the four orientation quadrilaterals corresponding to the four orientation coordinate sets, and the four orientation quadrilaterals have a common corner point, that is, the primary center point; then, a target quadrilateral located at the true midpoint area of ​​the region is determined through the four orientation quadrilaterals, and the center point of the target quadrilateral is determined as the target center point; further, a point name corresponding to the region is generated at the target center point.

[0044] It should be noted that, in this embodiment, a boundary longitude and latitude coordinate set is obtained based on the boundary of the region in the map, a primary center point is obtained based on the boundary longitude and latitude coordinate set; multiple orientation coordinate sets are determined based on the boundary longitude and latitude coordinate set and the primary center point; orientation quadrilateral corner point information corresponding to the orientation coordinate set is determined based on the orientation coordinate set and the primary center point; a target center point is determined based on multiple orientation quadrilateral corner point information, and a corresponding point name is generated at the target center point. Through the above implementation, regardless of whether the edge rule of the region boundary is or not, a preliminary center point, that is, a primary center point, can be generated based on the region boundary first; then, the longitude and latitude coordinates of each boundary point on the region boundary (that is, the boundary longitude and latitude coordinate set) are divided into different orientations based on the primary center point, so as to obtain orientation coordinate sets corresponding to different orientations, and then a target quadrilateral located at the actual center position of the region is generated based on each orientation coordinate set, and then the center point of the target quadrilateral, that is, the target center point, is determined, and finally a point name is generated at the target center point, so that a point name can be generated at the true center position of the region in the map.

[0120] Embodiment 7

[0121] A method for generating a map point name is provided in Embodiment 7 of the present application. The method optimizes the "generating a point name at the target center point based on the target quadrilateral size and the point name size" in Embodiment 5. It should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments. The method includes:

[0122] S710: Obtain a boundary longitude and latitude coordinate set based on the region boundary in the map, and obtain a primary center point based on the boundary longitude and latitude coordinate set.

[0123] S720. Determine a plurality of azimuth coordinate sets based on the boundary longitude and latitude coordinate set and the primary center point.

[0127] S743: Obtain the size of the target quadrilateral based on the display screen size, the longitude and latitude span of the map, and the corner point information of the target quadrilateral.

[0128] S744A, determine whether the size of the point name exceeds the size of the target quadrilateral.

[0129] The point name size includes the character line width. With character line height The target quadrilateral size includes the actual width of the target quadrilateral on the display With actual height .

[0130] In an optional embodiment, if the character line width Larger than actual width and / or character line height Greater than actual height , it is determined that the point name size exceeds the target quadrilateral size.

[0131] In another optional implementation, if the character line width is determined Larger than actual width , and the character line width Greater than actual height and / or character line height Larger than actual width , then the size of the fixed point name exceeds the size of the target quadrilateral. It should be noted that the judgment method in this embodiment is to judge whether the characters of the point name can all be located in the target quadrilateral when the characters are arranged in the vertical direction when the overall length of the characters of the point name is horizontal and the overall length of the shape of the target quadrilateral is vertical.

[0132] S744B: If yes, reduce the size of the point name to obtain a new point name size.

[0133] The initial size of the point name is 16px. If the point name size is determined to exceed the target quadrilateral size, the point name size is reduced by 2px each time. For example, if the point name size is determined to exceed the target quadrilateral size, the point name size is reduced from 16px to 14px, which is the new point name size.

[0134] Specifically, if it is determined that the point name size exceeds the target quadrilateral size, it means that the characters of the point name will exceed the target quadrilateral. At this time, the point name size of the point name is reduced to obtain a new point name size, and then return to execute step S744A.

[0135] S744C: Otherwise, generate a point name corresponding to the point name size at the target center point.

[0136] If it is determined that the point name size does not exceed the target quadrilateral size, it means that the characters of the point name do not exceed the target quadrilateral, which means that the target center point of the target quadrilateral is suitable for generating a point name corresponding to the point name size.

[0137] Specifically, if it is determined that the size of the point name does not exceed the size of the target quadrilateral, a point name corresponding to the size of the point name is generated at the target center point of the target quadrilateral.
