Research shows that in scenes such as world games and the meta universe, in order to make the constructed world map more vivid and bring immersive experience to users when constructing the world map, art developers are usually required to set objects in each scene through a scene development tool and in combination with a manual editing mode according to actual requirements of each scene in the map, and set specific rendering details such as materials of each object, and the process usually consumes a large amount of labor cost and time cost, so that the construction efficiency of the world map is low.

Based on the research, the map construction method can screen the map based on the screening conditions corresponding to the attribute features of the map elements, and can determine the target area meeting the screening conditions, so that the target area in the map can be quickly positioned according to the development requirements of the user; and adding the target scene elements which accord with the scene element distribution characteristics in the target area according to the scene element distribution characteristics corresponding to the target area aiming at each determined target area, so that the scene elements can be automatically added in the target area, and the added scene elements all accord with the scene element distribution characteristics, thereby rapidly constructing the map on the premise of ensuring the map quality and improving the construction efficiency of the map in the world.

To facilitate understanding of the present embodiment, a map construction method disclosed in the embodiments of the present disclosure is first described in detail, and an execution subject of the map construction method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, where the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, or a server or other processing devices. In some possible implementations, the mapping method may be implemented by a processor invoking computer readable instructions stored in a memory.

Referring to fig. 1, a flowchart of a map construction method provided in the embodiment of the present disclosure is shown, where the method includes S101 to S103, where:

s101: acquiring an initial map and at least one group of screening conditions corresponding to the initial map; each group of screening conditions comprises at least one screening condition, and each screening condition corresponds to one attribute feature of the map elements in the initial map.

S102: and aiming at each group of screening conditions in the at least one group of screening conditions, determining a target area to be edited which meets the group of screening conditions.

S103: and aiming at each determined target area, adding target scene elements which accord with the scene element distribution characteristics in the target area according to the scene element distribution characteristics corresponding to the target area so as to construct a scene map corresponding to the initial map.

The following is a detailed description of the above steps.

For S101, the map elements are elements included in the initial map, or elements constituting the initial map, such as land, river, and the like, and the attribute features include at least one of a height feature, a shadow feature, an orientation feature, a category feature, an edge feature, and a gradient feature.

The height feature is used for representing the height of the map element, and the corresponding screening condition can be, for example, the height is higher than 100 meters, so that the map element with the height higher than 100 meters can be determined from the initial map; the shadow feature is used for representing the shadow of the map element, and the corresponding screening condition can be that the shadow area is larger than 10 square meters, so that a shadow area with the shadow area larger than 10 square meters can be determined from the initial map; the orientation feature is used for representing the orientation of the map element, and the corresponding screening condition may be, for example, map elements whose orientations are east and whose left and right are respectively spread by an angle of thirty degrees (i.e., 60 ° north to 30 ° east), so that the map elements meeting the orientation angle requirement can be determined from the initial map; the category features are used to characterize categories of the map elements, such as land, river, etc.; the edge feature is used for representing the edge of the map element, and the corresponding screening condition can be that the edge of the map element of which the type is the target type is obtained from the initial map; the gradient feature is used for representing the gradient of the map element, and the corresponding screening condition can be that the gradient is 20-50 degrees, so that the map element meeting the gradient requirement can be determined from the initial map.

In practical application, the screening conditions can be combined by a user at will according to requirements, and each group of combined screening conditions can screen the area of the initial map from the dimension of at least one attribute feature, so that the target area to be edited, which meets the screening conditions, is obtained.

Therefore, by setting various attribute characteristics for the user to carry out free combination and parameter setting, the target area meeting the requirements in the initial map can be quickly and accurately positioned according to the development requirements of the user, and the construction efficiency of the map in the world is improved.

For example, taking development requirements as an example for editing in a basin in an initial map, a set of screening conditions that can be obtained according to the development requirements includes: the height is less than 0 meter (namely below sea level), and the gradient range is 0-10 degrees (namely the terrain is flat and the fluctuation is small). And screening the initial map according to the set of screening conditions, namely determining the basin to be edited from the initial map.

In a possible implementation manner, after the target area to be edited which meets the set of screening conditions is determined, an area optimization strategy can be further obtained; and adjusting the area range of the target area based on the area optimization strategy.

Here, the region optimization strategy includes target parameters for adjusting the region range, such as a minimum area threshold, and the region to be adjusted can be determined by the target parameters in the region optimization strategy.

Specifically, the area range of the target area may be adjusted by:

mode 1, deleting a target region whose area is smaller than a minimum area threshold of a region included in the region optimization strategy.

Here, since the target area is determined according to the screening condition, some areas with a smaller area may be determined from the initial map, and these areas often do not meet the actual development requirement, so that the minimum area threshold of the area may be set, and the target area that does not meet the area requirement of the area may be deleted.

For example, taking the minimum area threshold of the region as 1 square meter as an example, the target region with an area smaller than 1 square meter may be deleted.

And 2, adjusting the included non-target area in the maximum area range corresponding to the target area to be the target area.

Here, due to the uncertainty of the map elements in the initial map, when a target area is determined according to a screening condition, a non-target area may exist in a maximum area range corresponding to the target area, where the maximum area range corresponding to the target area indicates an area including the target area and having a maximum area, which is formed by an area edge of the target area.

For example, a schematic diagram of the target area before adjustment may be as shown in fig. 2a, a shaded area is a target area, a blank area is a non-target area, and the schematic diagram of the target area after adjustment may be as shown in fig. 2b, where in a maximum area range corresponding to the target area, after the included non-target area is adjusted to the target area, the maximum area range corresponding to the entire target area is the target area.

In this way, the target area after the area range is adjusted can be tidier, so that the scene element can be added to the target area in the following process.

Here, the scene element may be a ground surface material map of the target area, and the ground surface material map may be rendered on the ground surface of the target area to better show regional features of the target area.

For example, taking the target area as the basin as an example, a surface texture map corresponding to the basin may be added to the surface of the target area, so that the display effect of the target area is more realistic, and an immersive world-wide tour experience is provided for a user.

In addition, the scene element can also be a model of various organisms, such as prefabricated models of organisms such as flowers, grasses, trees, sparrows and the like, wherein the prefabricated models comprise rendering parameters of the scene element, and after any scene element is added in the target area, the scene element can be rendered according to the rendering parameters in the prefabricated models corresponding to the scene element; the scene element distribution characteristics may include homogeneous scene element distribution characteristics, and/or heterogeneous scene element distribution characteristics.

For example, the homogeneous scene element distribution characteristic may be that a distance between a root of a tree a and a root of a tree B is greater than a first preset value, where the first preset value may be a sum of half of a lateral length of a crown of the tree a and half of a lateral length of a crown of the tree B, that is, the crown of the tree a and the crown of the tree B in the target area do not intersect; the different scene element distribution characteristics may be that a distance between a root of the tree C and a grass root of the grass D is greater than a second preset value, the second preset value may be a radius of the root of the tree C, that is, the grass D may be placed at any ground surface position other than the root of the tree C.

Therefore, by setting the scene element distribution characteristics, the distribution of each scene element in the target area can be ensured to meet the actual condition, and the constructed scene map can be more vivid.

In one possible implementation, as shown in fig. 3, the target scene element may be added by:

s301: determining the type of the scene element to be screened corresponding to the area type of the target area, and randomly adding the scene element to be screened in the target area according to the type of the scene element to be screened.

Here, the area type of the target area may be determined by the attribute feature corresponding to the screening condition, for example, the area type of the target area may be determined to be a high-altitude area, a low-altitude area, or the like according to the height feature; when the type of the scene element to be screened corresponding to the area type of the target area is determined, the type may be determined according to a preset mapping relationship between the scene type and the type of the scene element to be screened, for example, the scene element to be screened distributed in the target area where the scene type is a high altitude area may be a mountain plant.

Specifically, when the scene elements to be filtered are randomly added to the target area according to the types of the scene elements to be filtered, the position information of each scene element to be filtered in the target area may be randomly generated, and the parameter values of the rendering parameters corresponding to each scene element to be filtered are randomly generated within a preset parameter range, where the number of each type of scene element to be filtered may be randomly generated within the preset parameter range, or may be set by a user, for example, the user may set 5 trees and 10 grasses to be randomly generated within the target area.

S302: and screening the scene elements to be screened in the target area based on the scene element distribution characteristics, and determining the target scene elements which accord with the scene element distribution characteristics in the scene elements to be screened.

In a possible implementation manner, when the scene elements to be filtered are filtered, the at least two scene elements to be filtered in the target area may be filtered based on the attribute information of the at least two scene elements to be filtered and the scene element distribution characteristics.

Here, the attribute information of the scene element may be represented by the rendering parameter, for example, if a tree height in the rendering parameter is 5 meters, the attribute information of the tree a may represent that the tree height is 5 meters, and when the at least two scene elements to be filtered are filtered, if the at least two scene elements to be filtered are the same kind of scene elements, the at least two scene elements to be filtered may be filtered by using a filtering condition corresponding to the distribution characteristic of the same kind of scene elements; if the at least two scene elements to be screened are scene elements of different types, screening the at least two scene elements to be screened by using screening conditions corresponding to the distribution characteristics of the scene elements of different types; and if the scene elements with the same type and the scene elements with different types exist in the at least two scene elements to be screened at the same time, screening conditions corresponding to the distribution characteristics of the scene elements with different types can be used for screening the scene elements with different types in the at least two scene elements to be screened, and screening conditions corresponding to the distribution characteristics of the scene elements with the same type can be used for screening the scene elements with the same type in the at least two scene elements to be screened.

For example, taking the scene elements to be screened as tree a, tree B, tree C, and grass a as examples, whether the tree a and the tree B, the tree a and the tree C, and the tree B and the tree C meet the screening conditions corresponding to the distribution characteristics of the same kind of scene elements, and whether the tree a and the grass a, the tree B and the grass a, and the tree C and the grass a meet the screening conditions corresponding to the distribution characteristics of the different kinds of scene elements may be respectively determined.

Specifically, when it is determined that the attribute information corresponding to the at least two scene elements to be filtered respectively does not meet the filtering condition corresponding to the scene element distribution characteristic, any scene element to be filtered in the at least two scene elements to be filtered may be deleted; or, according to a preset correspondence relationship between the importance degrees of the scene elements, deleting the scene element to be screened with the lowest importance degree of the at least two scene elements to be screened, for example, if the importance degree of the tree is high, the importance degree of the shrub is medium, and the importance degree of the grass is low, preferentially deleting the grass with the low importance degree of the at least two scene elements to be screened; or, the attribute information of the scene elements to be filtered may be adjusted according to the scene element distribution characteristics, so that the at least two scene elements to be filtered conform to the scene element distribution characteristics.

It should be noted that, after the scene element to be filtered is deleted (or the attribute information of the scene element to be filtered is adjusted), if the scene element to be filtered in the target region from which the scene element to be filtered is deleted (or the attribute information of the scene element to be filtered is adjusted) still does not conform to the scene element distribution feature, the process (deleting the scene element to be filtered and/or adjusting the attribute information of the scene element to be filtered) may be continuously performed until the scene element to be filtered existing in the target region conforms to the scene element distribution feature.

The map construction method provided by the embodiment of the disclosure can screen the map based on the screening condition corresponding to the attribute feature of the map element, and can determine the target area meeting the screening condition, so that the target area in the map can be quickly positioned according to the development requirement of a user; and adding the target scene elements which accord with the scene element distribution characteristics in the target area according to the scene element distribution characteristics corresponding to the target area aiming at each determined target area, so that the scene elements can be automatically added in the target area, and the added scene elements all accord with the scene element distribution characteristics, thereby rapidly constructing the map on the premise of ensuring the map quality and improving the construction efficiency of the map in the world.
